Hi, would a regular charger be better to use vs the turbo charger for the longevity of the battery? Would a regular charger work ok with this phone?
Thanks

With the turbo charger the device gets pretty warm
Hard to say but I don't think the turbo charger would damage the battery since it actually only ships with it. I would be surprised if it is a problem.
The way I understand it is that the turbo charger will step down as the battery reaches a fuller charge.
You can use the turbo charger on older devices without issue as the circuitry will account for this.

I don't think Qualcomm would design a charger that would speed up the life of a battery because that would give them a bad reputation. I've used the quick charger since I got my Nexus until today because now I use my TYLT qi charger. I have noticed no negative effects of using it, and as stated the chip set is what dictates the charging speed. The chip will not let the battery get too hot assuming the chip is working so I would not worry.

Also forgot that if the battery gets too hot charging will stop as Pilz mentioned above. I have seen this before on my SGS5 with wireless charging as it can generate a good amount of heat. I would imagine the Nexus 6 is the same.
Okay. A quick lesson on chargers may be in order.
What you'd consider a regular 2A charger, is actually a "Quick Charge 1.0" charger, which charges at 5V @ 2A, for a total of 10W of power. A Quick Charge 2.0 charger, which Motorola calls a "Turbo Charger" charges at 5V, 9V, and/or 12V @ up to 3A each, for a total of 15, 27, of 36W respectively. Thus, in theory, a QC2.0 could charge up to (almost) 75% faster than a QC 1.0 charger. That's where that number that's being touted around comes from. The reality, so far though, is far different.
The Moto charger does actually charge at all three voltages (whereas most QC 2.0 charger only seem to charge at 5V and 9V), but it charges @ 1.6A in 5V mode (8W), 1.6A in 9V mode (14.4W), and 1.2A in 12V mode (14.4W). Thus, in the top two modes, it charges at just under the equivalent of a 3A "normal" (QC 1.0) charger, then drops down to about 80% of a standard 2A charger when the battery gets close to full.
With more power (watts) comes more heat, so yes, the battery does appear to get a lot warmer than with your normal charger. However, it's still well within the "normal" range that your battery was designed to handle. It may feel warm (or even hot) to you, but trust me, your battery is fine. In fact, there are safeguards in place to protect your battery. If you battery ever gets too hot, your phone will shut down and stop charging altogether. Some owners of a Tylt Vu can attest, since that particular charger has a reputation of wireless charging problems that caused the phones' safeguards to kick in. You should know though, that by the time that safeguard even kicks in, the phone will become MUCH too hot to touch. If you THINK that the phone is too hot, then it isn't. Believe me, the blisters on your fingers will let you know when a battery REALLY reaches a dangerous temperature. If you're able to hold onto the phone for more than a few seconds, then the battery is certainly not in any danger.
In a normal QC 2.0 charger, will that small amount of excess heat reduce the life of your battery? Technically, yes, but the same can be said about charging it with that 2A charger, vs. the 500mA USB port on your computer. It may reduce the life by a month or so, and still last more than double the 1 or 2 years that you're likely to own your phone. In short, don't worry about it. Your battery will likely still last MUCH longer than you'll need it.
Thnx for all the input!

Very nice, thanks for this :good:
@jt3 Thanks for the explanation. I would think the voltage somehow plays a part in this, right? As you pointed out, if you look at straight watts, our Quickcharger is only putting out 44% more power versus a last gen phone. Also, since our charger supports both 9v and 12v at 14.4W, that further points to the idea that voltage plays a part here. I would assume it affects the efficiency of the charge? Otherwise why not just build this with 5v and 3 or 4 amps?

Yes and no. The reason for changing the voltage instead of the current has to do with something called Joule Heating, and if you thought my last post was technical and complicated, you just dropped down the rabbit hole.
Think of it like a garden hose. Voltage would be the diameter of the hose. Current would be the rate in which water flowed through the hose. If, say, you wanted to fill your dog's water bowl, and for some insane reason, you want it to take exactly 30 seconds to do so. You could either get a larger diameter hose, and turn down the flow of water, or get a smaller diameter hose and turn up the flow. In the end, the dog's bowl gets filled in the same amount of time. (Electrical Engineers will likely gripe and say that the diameter of the hose is more accurately Resistance, rather than Voltage. Yeah, well... shut up! This is my story! Seriously, I'm being a bit inaccurate, but it makes it easier to picture this way.)
Same thing here. By cranking up the voltage (volts), they can turn down the current (amps) to achieve the same power (watts). In the case of the 12V vs. 9V on the Turbo Charger, it's the same exact power, which doesn't seem to make sense, and furthermore (as you said), why not just keep it 5V and raise current to 3A, since that's also (more or less) the same amount of power? Okay, remember that dog bowl? what happens when you really crank the water flow and point it toward that dog bowl? It splatters, and because of this, a measurable amount of water actually ends up outside of the bowl -- wasted. Same thing here. By cranking up the current, you lose more in the form of heat. By dialing that down (but keeping the power the same, by raising the voltage), you can reduce the heat generation at the same power level.
So... The "tl;dr" of it all is that a 12V charger, pushing (around) 15W of power generates less heat than that 5V, 3A charger would, even though the power is the same. The heat generated isn't huge at these small numbers, but we're talking REALLY confined spaces, with no fans or really any form of ventilation. A few degrees here and there can really make a difference.

Last nite, I played dead trigger until battery warning indicated 4%.
But I still keep playing and suddenly the screen went black.
I think the battery is totally dried out at that time. So I used the following
charger but failed to charge even after 10min. Here's the charger:
1. 3rd party 5V 3A charger,liteon brand.
2. old nokia 0.5A charger.
3. original samsung note2 charger.
all those 3 charger works normall on my n10 before last nite.
and suddenly i think maybe i can try out the original charger of n10.
And it works!
So i wonder if samsung or google put special charger on the adapter?
Before we know anything furthur.pls put ur n10 charger in safe place.
I think most tablet chargers output a voltage of 12v. That might of kicked your battery back to life.

I've confirm the voltage of my n10 adapter. Which printed "5V 2A".
It probably just needed a certain amount of minimum battery voltage to function and show charging. I doubt if the OEM power supply is special in any way. The charging circuit is really inside the N10.

when i plug in the non-n10 charger, even after 10min,n10 is not able to boot. Only flaahing the battery charging symbol for 1 sec.
when i plug in the original charger, n10 can be boot instantly.
thats why i think it is very weird about the original charger. but other chargers still works well when n10 battery is NOT completely dried out.

Yeah, that is very strange indeed. It does draw in the 1800mA range from the battery during boot up. Are you using the same micro-USB cord all the time? It was reported that there are big differences in charging rate with different brands of cords.
This was covered in another thread recently.
Basicially the Samsung chargers have 2 pins shorted together to get full charging power of around 1.5A with the n10. Using other chargers will get you around 500ma output.
My guess is if you left your tablet on the "other" chargers overnight it would come on just fine. They simply don't output enough juice to power the tablet when the battery is that low.

Had you left the other chargers on long enough, the tablet would have booted fine. I've run into this. I have an old(er) Samsung Tab 2 10.1 charger I use with my N10 (now along with a Pogo cable) and my N10 charges rapidly. That, coupled with the two wires shorted out in Samy's setup for the larger amp's.....also, in my job, I work with other chargers all the time and use them all the time across multi platforms, to include my N10, and it charges fine (albeit much more slowly).

Should still work fine. Voltage is the same and the device will only draw as much amperage as needed. May have something to do with the circuitry in the charger? It may have been bad. As long as you don't supply more volts you are OK. More amps is also OK. Not enough amps will lead to burning up the charger unless the device is smart enough to realize its on a low amp charger (like the n10) and kick down so as not to over draw (ie - over drawing from the USB port which is a .5amp (500mAmp) or 1amp (1000mAmp)...someone correct me on the number here please)
The whole reason manufacturers tell you not to use someone else's charger is so you don't plug in, say, a 12 volt charger into a 5 volt item. That would pop something. That or some cheap charger poorly built could allow "dirty" power through causing problems. Both issues voiding warranties
Not sure if it's been mentioned, but depending on the usage of the tablet, you might not be able to charge it quicker than the power usage. For me, if I'm playing a demanding game at 1.7Ghz and max brightness, neither USB or Pogo can charge the tablet, and battery still drops (slower, but still drops).

Never seen anything burn up because of low amperage., power or watts generate heat and power(watts)=voltage x current.
Did you ever see a PS(charger is inside the N10) with a USB port that supplies anything but 5V? I haven't.
Current (amps) does the charging.
No USB charger will provide anything more than 5.1 volts. If the charging block has a USB plug look at the rating. Amperage for smaller devices may be 1a or even less. Newer big smartphones have bigger batteries and need more current to charge. My old Thunderbolt charger is 1A, the charger Motorola provides for my Maxx HD is 1.5A, the Samsung charger for my Galaxy Tab 2 7.0 is a 2 amp charger, so is the charger for the iPad that some frickin' jerk ripped off from my house. The Xoom escaped that problem by having a separate charge plug, not using the USB system, it 12 volts at 1.5 amps. See the pattern? A tablet of any kind has an even bigger battery and needs even more current to charge. The reason the N10 may lose charge even when plugged in is that the charger can't deliver the current needed to run the device and charge the battery simultaneously.
As I see it, Samsung and Google need to supply a slightly higher amperage power block to compensate for the use/charge balance problem. Our solution would be to turn it off and charge the device every night or even leave it plugged in when not in use.
Another thing is the surface area for current transfer. The USB points are tiny, the POGO Pins, dedicated to charging would be able to handle more current because they have more surface area.
Any one who knows better may correct me, I just ordered an N10 today from Google so my information here is what I have read here and what I know from years in the electronics field..

You don't need more current to charge a bigger battery, it's all about how long it will take to charge to full.
Some have stated that they've seen a 3A battery drain with certain games. The 9Ah battery would last approx. 3 hours which exceeds the max rate of the charging circuit and the PS. Even on a fully charged battery at that rate doesn't last that long.
AFAIK for any tablet to be able to draw 2A from any 5V charger (that can supply the needed amperage) the data pins (middle two pins from the use cable) have to be at 2.5V. Otherwise even if the charger is with correct specifications 5V/2A the tablet might not charge at all, or charge at a lower rate.

I forget the actual brand/model of the actual charging chip but if you poke around in the N10 files you can find it but it's specs are list as 2.5A max but N10's code limits it to 2.1A. This isn't the PS wall wart commonly called the "charger".
The recommended charging current for any lithium ion or lithium polymer is 0.7C. What that actually means is a current 0.7 x max capacity in mAh. For most phones e.g. my Galaxy Note 2 with a capacity of 3100 mAh this means a current at about 1.7A.
The battery Nexus 10, on the other hand, could very well be charged at a whooping 6.3A current.
In USB Battery Charging Specification 1.2 the maximum current a USB port can supply for charging purposes can be as high as 5A.
With the Perseus kernel for Note 2 you can actually specify the max limit for how much current the phone will draw from any charger.
So in theory.. it should be possible to charge the Nexus 10 with a 5V 5-6,3A charger.. and that would probably be very quick!
For the record: I havn't seen many (any?) chargers with more that 2.3A

Sure the charging rate is way under what it should be but as they use larger and larger capacity cells the only solution is a removable cell to charge by other means.
Hi everyone.
I recently got the Xperia Z and noticed the original charger packs a 1500mAh speed (which got me confused because I thought AMP referred to charging speed), but anyhow. I also bought a power bank (external backup battery) and the thing has 2 ports, 5V 1AMP and another 5V 2.1AMP. So I was wondering if the Z can take the 2.1AMP speed without damaging the battery. What do you guys think?
Thanks.
You won't harm it instantly no. Over time, yes.
The battery lives better if you charge it slowly, I charge mine with 500mA when I go to bed. I'd use the 2ma if you were really rushed.
My Stock charger is 1800mA btw. (Dock)
The phone will automatically limit the charging current (amperage), so the battery won't be charged too fast even if you use a 2A charger. I do not know at what amperage the XZ limits the current, but I suppose it's somewhere around the 1500mA of the standard charger.
On the other hand, charging with very low currents may also damage the battery. I read somewhere that prolonged use of a charger with less capacity than around 0.5c (c=the capacity of the battery; 2330mA) might be bad for the battery. Therefore it isn't recommended to only use the USB port of your computer (500mA).
So, for repeated use over long periods of time, a charger with a capacity of over 1165mA (0.5c) is recommended.
Well I don't know what to believe anymore :x
You can safely charge with almost any trusted-brand MicroUSB charger. As long as it's not broken or a cheap chinese knock-off or anything like that. It will output only as much as the phone will accept.
EDIT: 2.1AMP (as you state it) is 2100mA (milliamperes). That's it's current output. It does not refer to "speed" per se, but a battery will charge faster with a higher output charger. A 1000mAh battery will charge from 0 to 100% in one hour if you use a 1000mA charger. Or in half an hour with a 2000mA charger. That's the theory.
In reality, phones and batteries will have safety circuits that limit the charging current so that the battery won't get damaged. It simply will not charge faster than what's safe. If, say, our XZ is limited at 1500mA, then it won't let in more than 1500mA. No matter if the charger is rated at 1500mA or 2000mA. The phone will, however, accept less than 1500mA, but when the current sinks below a certain limit, the phone won't charge at all. That lower limit might be somewhere around 400mA. If your computer's USB port gives out considerably less than 500mA (which is the norm), then there might be something wrong with the port and the phone won't accept it.
For comparison, the Samsung Galaxy S II won't charge at any higher than 700mA. No matter if you connect it to a 700mA or a 2000mA charger, it will only take 700mA and that's it. The stock SGSII wall charger is 750mA.
The XZ, having a bigger battery, will charge at higher than that. I'm guessing 1400-1500mA because the stock charger is 1500mA.

Awesome then, thanks a lot for your help
Let's face it. It's always best to go with the original charger. If you use a non standard charger the best practise is to use one that has a similar amperage. That said, my Power Bank case puts out 1amp via the dock pins, so... And it's made for the Xperia.

Ride it like you downhill it.
After looking up a bit on USB car chargers, many people seem to recommend the Scosche Dual USB Car Charger (reVOLT 12W + 12W). Each USB port outputs 2.4A of power to charge any device (there's a known issue with this charger for some non Apple devices, you should use charge-only USB for those), but our HTC One stock charger outputs only 1A.
I am afraid a fast car charger like this one will easily overheat my battery, charging it much faster than usual and degrading its lifespan. Should I worry about this or can I order this charger and not worry about it?
I'm confused because a lot of people recommend car chargers like this one (with more output power than what the stock charger of your device gives you) and no review mentions the issue I'm raising here. Is this a non-issue?
Would appreciate more information on this topic from more knowledgeable people in this area.

I'm no expert here but it is my understanding that the phone will take what it requires to charge no matter if you have a 1A or a 2A charger meaning that you will be wasting the power delivered by the charger. I don't think it will affect the battery nor will make it charge faster as I think the internal logic of the phone would not permit so. It could also be the case that HTC limited the power output on the charger but not on the phone meaning that in this case it will charge faster, and I think degrading battery life. Anyway, if you have someone with a higher amp charger you can test this yourself by measuring the time it takes to fully charge with the original charger and the other one. It will not really have an impact in battery life if you just try.
I guess I didn't respond to your question actually! Sorry

You definitely aren't expert, neither am I, but there are couple things:
You were right about that, that device should pull only as much as it needs.
But he won't waste power (in ideal world). As the phone pulls only 1A from 1A or from 2A charger, he still be pulling 5Vx1A = 5W.
Now, to the original question.
Basically every device pulls as much as it can / needs. The Amps on charger says about how much can it deliver maximum.
The question is, how is constructed htc charging circuit. Whether it relays on maximum from charger, or it has internal limitor..
I will try to make an example to make it clearer:
Imagine, that you have a tube made of glass and a reservoir full of water. Tube is your phone and reservoir is charger.
Now, 2 situations can ocur:
1, Tube is made of very thin glass and it relays, that there won;'t be bigger pressure (more water) in reservoir. If there would be more, tube would crack.
2, Although tube is made of thin glass, it has some mechanism included, let's say pressure regulator on the beginning to reduce the pressure.
Now the question is, which of these cases is our phone about.
In short, the HTC One will pull only 1A out of your charger, regardless of whether it's 2A or 100A. The only way you can make it pull more than 1A is by installing a custom kernel like ElementalX or Bulletproof and ticking on 'Enable USB fast charge' which is disabled by default because it shortens the battery's life.

You definitely aren't expert, neither am I, but there are couple things:
You were right about that, that device should pull only as much as it needs.
But he won't waste power (in ideal world). As the phone pulls only 1A from 1A or from 2A charger, he still be pulling 5Vx1A = 5W.

What I meant to say is that it would be wasting a 2A charger whilst the phone only seems to require 1A, not meaning that the charger will still be delivering at maximum capacity (2A).
Guess none of us could answer his question as we still don't know how the phone handles the charge.
Subjective answer from an anonymous noob, but I charge my phone with a 2.1A wall charger (built into a power board) and there's no perceptible change in charge rate. I've also used a cheap portible charger, a lithium 800mA, and that battery gets HOT like my m7 is pulling 1A just because it detects it's not limited to usbs 500mA (the power dialog reports AC charging mode).
So it seems to me to be a simple 2 mode as shown as a status in the power dialog, either usb or AC. But, I haven't actually measured or tested anything; this is all just casual observation and assumption.
Can I blow up my USB device?
There is a huge variance, then, between normal USB 2.0 ports rated at 500mA and dedicated charging ports which range all the way up to 2100mA. This leads to a rather important question: If you take a smartphone which came with a 1A wall charger, and plug it into a 2A iPad charger, will it blow up?
In short, no: You can plug any USB device into any USB cable and into any USB port, and nothing will blow up — and in fact, using a more powerful charger should speed up battery charging.
The longer answer is that the age of your device plays an important role, dictating both how fast it can be charged, and whether it can be charged using a wall charger at all. In 2007, the USB Implementers Forum released the Battery Charging Specification, which standardized faster ways of charging USB devices, either by pumping more amps through your PC’s USB ports, or by using a wall charger. Shortly thereafter, USB devices that implemented this spec started to arrive.
Fast forward to 2013 and the HTC One. It is equipped with a USB 2.0 port and when no data is transferred it will accept a charge up to 1A with a minimal standard of 500mA. When you buy a charger that says 2A output, this normally means a max of 2A for the charger. When it comes to charging the phone, the phone will only pull enough power it can from the charger and not more.

Now a days Car charger is so essential for us. But when we chose A Car charger for our device its not match, so it s harmful for us & its some time cases to damage our device.
Most of the time The power out put of the car its 12V or 24V. and The Charger give different out put for different device. And its a major thing about the charger whats Ampere given output. Avantek Car charger give us different option ; I think its give different out for our device. Avantek take also help auto adjust to the device. So its protect the device.
I Use Avantek Car Charger for my family & You can also try it for your device.

After looking up a bit on USB car chargers, many people seem to recommend the Scosche Dual USB Car Charger (reVOLT 12W + 12W). Each USB port outputs 2.4A of power to charge any device (there's a known issue with this charger for some non Apple devices, you should use charge-only USB for those), but our HTC One stock charger outputs only 1A.
I am afraid a fast car charger like this one will easily overheat my battery, charging it much faster than usual and degrading its lifespan. Should I worry about this or can I order this charger and not worry about it?
I'm confused because a lot of people recommend car chargers like this one (with more output power than what the stock charger of your device gives you) and no review mentions the issue I'm raising here. Is this a non-issue?
Would appreciate more information on this topic from more knowledgeable people in this area.

Yes, fast usb car chargers may harm your device. Because if device get power more than its capacity then it would be definitely harm your costly devices. So please purchase a perfect and valuable charger for your devices long life.
Also quick note using a charger that charges your device faster will decrease the life of your battery, remember slow charging is best for the battery and that goes for all batteries
To answer conclusively as I have before:
I've had many many many phones and this is what I've learned over the years through experience and a lot of searching. Our phones are designed for whatever rating it is on the stock charger, which is 1A. However we have chargers that support more current. Which leads us into the next part.
Phones will only "pull" what is it rated for. It controls the final pressure valve in the water metaphor. In this example. Our phones are rated 1A Max @ stock kernel. "Extra power" isnt and cannot used up due to this rating. hence no extra loss except on your wallet. Fast charge raises the rating and limits vary from kernel to kernel. I've used my phone with a 2.4a charger + fast charge enabled before and its fine. Its a little warm (more on that in next paragraph) I'm on "dirty unicorns" ROM and I haven't gotten around to checking the limits
Regardless.. Whether it is detrimental to your phone battery is personal choice as having the % below 40 and heat is #1 enemy to batteries. Our batteries are designed for 5 years max anyway. If you want to play it safe, get a 1A charger and a max 6ft cable as more = less current. Make sure this cable is not from eBay or has sufficient guage size as the copper in some eBay cables can be thinner than your hair. This is important.
If you're looking for unpractical long term savings. Keep your phone room temperature within its temperature rating. Keep charge above 40%, optimally around 80% as lithium batteries degenerate when kept near 100% for too long. (See how frail our current battery designs are? There are higher battery tech our there, but due to cost none are in phones)
I've had horrible horrible power efficiency Roms before and as worst, it just stays on one % value without dropping (no fast charge, 1a charger)
Charging only cables are useless because since 4.3 kernels, android supports iPhone chargers as well.
In addition, car chargers have built in voltage regulators in them, our 12v car source can actually range from 8v to 30v depending on conditions. 8v on crank, and during cold days, 14.4 alternator running, 24v on car boosts. Most car 12v ports are unregulated and Most car chargers operate around 11-15v and give off excess power as heat. Given this, in truly exceptional cases, unless you deliberately overload the charger, we're still good as 5v from a GOOD charger are pretty stable for the phone. Monoprice sells good chargers with good electronic internals for a very good price. Bad chargers pass off this electrical noise to your phone.
TL-Dr.. no difference between 2.4a and 1a. Phone takes what it is rated for(1a). Extra isn't used. Fast charge kernels can increase this rating at a slight warming of phone. In all cases, heat / below 40% = more detrimental to battery life than current speeds. Get a good cable with good gauge size. (Copper width)
If you need further proof, google the terms I have presented or search XDA. There has been many "conclusive" posts on this matter and you'll find many of them say this same exact thing.
Phew.. What a long post.

Smart IC Powerful USB Car charger will determine the electric current which your phone needs
Sold by HAWEEL and Fulfilled by Amazon
ASIN: B00Z65KBVM
HTC m7 can take max 1.5A but it seem to not work with many chargers, in such case it falls back to 1A.
But if youre using the phone for GPS navigation, then charging faster will just make it more hot (hot from usage + even more hot from charging) and it will stop charging anyway (because of the heat).
Also, heat is biggest enemy of batteries, the hotter it gets while charging the worse it is for the battery.
Hello! I m using a generic 2.5 mAh 5.0v Charger is it going to hurt my Battery or Mobile OR not????
You can use any micro usb charger, kernel will limit the current.
i'm using "generic" (connectIT) dual usb 2.1/3.1A charger without problem...
btw edit the thread name - charger is spelled wrong (just to help other people with searching in the future)
from the first day on my purchases using g2, more than a year.
It's common sense that higher current = more heat = faster li-ion/lipo degeneration. If you occasionally need a 2+mAh charge, it won't really hurt your battery too much. However, for everyday charging, stick with ~1mah in order to preserve your battery. I personally use an 1mah(5w) iphone charger because it's got the cleanest output out of all the readily available chargers. In my car I have a 2.1mah charger in case I need a quick top up.
Fyi, the phone will only draw a max of ~2mah regardless of what charger you use.

Yes, the phone will only draw as much current as it's designed to. You could hook it up to a 50a charger if you wanted and it would still draw less than the 2a limit regardless. The only thing that's important is the voltage which happens to be 5v on nearly all modern phones.

Hard to believe a word from you considering you can't even get the current unit right. It's amp aka A. Not mAh, which is both wrong in unit and scale (that's milliamp * hour, that's for capacity).
A typical USB BC compliant charger can supply up to 5V 1.5A, of course there are 5V 2/2.1A chargers around.
The charger only limits the maximum power a device can draw, it has nothing to do with the actual charging process if the device can't draw more than said maximum.
As for you your other baseless claims, typical Li-ion based batteries can at least charge at 1C, that is 1000mA=1A (of course this is actual charging current, which is approximately 1.2x the supplied current on a 5V charger) for a 1000mAh battery, 2A for 2000mAh battery and so forth. There's NO such thing as occasional "2+mAh" is safe. 1C is always safe and that actual number is tied to your battery capacity (5V2.5A would be perfectly safe for a 3000mAh/3.8V battery even if the phone actually took that current).

LoL That's Right
I've just come over from a Samsung s8 plus that was unfortunately stolen without insurance and couldn't quite bring myself to fork out another insane price for another one. Purchased this OP5 carrier free @ my local o2 here in England (as i had a £150 voucher).
As a consequence, I have accumulated a large amount of both Quick Charge and Samsung adaptive fast chargers.
It seems that the OP5 charges very quickly on these which relieved me, I would say def on a similar level to QC 2.0 and the Samsung.
of course the Dash charge is just ridiculously quick.
i was reading that the OP5 does not support quick charge and only dash charge.
I beg to differ?

I'd be hesitant to use a QC adapter with the OP5. You're taking a risk of damaging the battery, or worse, the phone. There are most likely slight difference in the charging logic between the two adapters. I'd email OP support to get more info.

seems to work just fine, i doubt an adaptive fast charger will cause damage as it will act like a regular usb charger. will ask- cheers
Different charger wont damage anything people.
Lithium based charging system is more complicated as acid or Ni based battery, but simple.
1 rule for the power supply, it need to keep the power output the more stable as possible. So use high qality charger, samsumg are just fine. I'm using a HTC.
You can take any charger you want @ 5v. from 0A to 4A. You can use a 100A, but the phone will draw only waht it need, and the wire gauge will limit the power draw.
Let say the wire is too small, the voltage will drop, the chip will detect it and reduce the demand.
dash charging or fast charging are just brand name, the physics is the same. The power supply has a higher wattage, because the device can take it.
And the USB wire has a higher gauge compared at standard.
Use dash chager on a old phone, and you wont have any benefit if the phone draw only 700mA.
Or simply take a desk adjustable power supply, set it @ 5v4A, plug OP usb cable or any big gauge USB, and OP5 will show ''dash charging''.
Conclusion.
Depends of the voltage/amp/gauge, not the branding.
** BTW , even with cheap power bank, power supply or any supply, I really doubt it will damage anything. On my wife op3, we use any bank ( even the budwizer one), we plug it with iphone supply, 120voutlet with the usb option, dash, kindle supple, etc. annnnddd it still working juste fine. She has, ebay cable also.
Well all the stuff is in the charging brick on the dash charger. All the heat it's dealt with in the brick. That means the brick from Sammy doesn't and more heat then the phone could safely handle may do damage over time? IDK but the we all know heat kills electronics.
I use a quick charge (the one of got for my Nexus 6P) on my op5 but only at my couch so I pull it off the charger when full, don't let it sit on charge when 100%
You can let it sit on charge at 100%. Phone will disable charging anyway.
i actually think OP have stealthily allowed the qualcomm quick charge to work as it charges almost exactly as the s8 did on the sammy brick. i used a non quick charge old LG brick and that charged waaay more slowly.
honestly someone charge using a quick charge or sammy adaptive fast charge brick and tell me if im right or wrong ...

I only have my dash and 1 Sam qc brick rest are cheap but with dash block it obviously says dash charging, with the qc it just says charging, and with the 3rd party bricks it says charging slowly. So hope that helps
Just download an app like ampere and monitor the current using the different chargers, then you will see if it's more efficient or not.
It might charge quickly using those other chargers but the heat won't be transferred to the charger like it is with Dash charge
Likely it is QC2.. only with dash charger it will go further and faster
any 3rd party cables that are dash charge compatible?, read somewhere its based on the thickness of the wire ...

But this is just plain wrong, dash charging has nothing to do with QC quick charge. It's as different as it can be!
QC quick charge:
The brick highers the voltage to more than 10v. This way, less amps go through the cable, the the wires can remain thin.
(P=U*I) --- e.g. --- Power = Volts * Amps --- example: 5v * 2a = 10w / 10v * 2a = 20w
This way, you can have a greater power while the amps remain the same, while using a normal, thin cable.
The voltage regulator/BCM in the phone takes the voltage down to safe levels for the battery. This creates alot of heat inside the phone, which is bad for the battery.
Dash charge:
Dash charging transfers the BCM to the charger, little to no heat is generated inside the phone!
The BCM controls the flow to the battery by altering the voltage.
U = I*R --- e.g. --- I = U/R --- e.g. --- Charging amperage = Voltage / Internal resistance of battery --- e.g. --- When the voltage is pushed up, the flow into the battery gets higher.
Remember, this is all done in the power brick, so the voltage of the electricity going through the cable is lower (3-6v I would say).
This translates to a higher current (amps), So the cables have to be thicker! That's why dash charging only works with official oneplus cables (and some OPPO cables, but those are all Micro usb).
In other words, there is no way dash charging works with other powerbricks!
I hope this clears up all the misunderstanding surrounding quick charging techniques.
Cheers!

yes i agree but it seems like the OP5 allows qualcomm quick charge (or some form of it) to work as ive checked and a quick charge brick charges much quicker than a regular non quick charge brick.
this seems like great news as the phone has a versatility between both techs. makes commercial sense for OP to allow QC (albeit at the same level as a S8 from my experience) to work as their dash tech limits brick and cable usage.

Yes, you are right, it could be possible (although unlikely) that oneplus has adopted 2 fast charging protocols in the oneplus 5.
I was just saying it can't dash charge using a samsung adaptor/cable.
I you want, I can try to hijack some cable to read out the voltage when the oneplus5 is being charged with a samsung adaptor.
That would be very interesting to see !!
Can't seem to get it to charge as fast as the OP5 charger, will post ampere reading here in a bit.

That's impossible, read my post above to see why
I checked the voltage while charging the OP5 with a QC charger It stays at about 5 volts, so there seems to be no QC capability in the OP5.
There is no QC functionality for the OP5. Regular charging, just draws power like a phone with neither QC or Dash. You can still get a relative fast charge from a higher output brick. (output 5v 1.2a-2a) Higher the amps, the faster the charge. Of course this is dependent upon cable quality and charge logic.
