I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!
----
in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.

Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
Hi,
I've got my phone with samsung's charger of 1A (bought it from an open store locally - it was the cheapest), so I ordered a Sony Ericsson charger of 1.5A which charges up much faster..
My question is, could it goes even faster?
I've seen some Galaxy Note 2 and S 4 charger of 2A like these:
http://www.ebay.com/itm/2A-USB-Wall...S_Cell_Phone_PDA_Chargers&hash=item5658d7a0bd
http://www.ebay.com/itm/OEM-2A-USB-...l_Phone_PDA_Chargers&var=&hash=item51aabf953a
Could our phone handle it and charge it with the whole 2A power? could it ruin the battery with that high Ampere?
I'm asking this because I've ordered a docking station like this:
http://www.ebay.com/itm/261247762140?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Which says 1.6A, so I was thinking perhaps theres stronger chargers out there for it..
Thanks!
im not sure about this but i believe the charger that comes with the phone is a 2 amp charger
It can handle 2A through USB port.
Via the charging dock, it can take 1.8A. Is that dock you are linking to an original part?
I have two DK26 docks and both say 1.8A, not 1.6A. Although if you connect a 2A charger to the dock, it'll be fine, it just won't be using the whole 2A input.

The Dock I've linked is a chinese copy, not the original, the one says 1.6A on description on Ebay, Does your original DK26 dock comes with charger too? What input and output is it says on each one? (picture could help much)
Also, how do you know it can handle 2A through USB? is that for sure?
Thanks for both!
The docks come barebone. No chargers included.
The charger included on the box of the phone is rated at 1.5A.
I have a Nexus 7 2A charger and an old Nokia 1.2A charger aside from the included 1.5A charger. All work fine either via USB or via the dock.
I can't notice any mayor difference on charging times, though. 1.2A charges almost as if not as fast as the 2A one. Iphone's 1A chargers do seem to take like 4 hours to charge the phone compared to the standard 2.5h I get from other higher rated wall chargers.
There are no 2A Sony chargers as of now.

I'm using a 2A as my car charger works perfect.

It should handel 2.A but I won't remand it. I don't think it's good for battery. But one thing is pretty sure. The phone will heat more up as the charging circuit have to dissipate more excess power. Can not affirm it as I don't exactly know it's made but I'm just saying...
"I know that my English isn't perfect, but I still hope it's comprehensible." Send over the cool Xperia Z
The downside would be possibly shortening the usable life of your battery, because the higher amp charging will likely heat the battery to a higher temp.
There's no free lunch.
To me, waiting a bit longer for charging is worth it to ensure the longest charge cycle life, particularly since the battery is sealed into the device. If it was a cheap and easy replaceable battery, maybe.
Amps don't matter unless it is lower than the specification
Think about your car battery having 700amps but your car stereo is fused for 20amps. Your car stereo gets its power from the battery directly. There is no power regulation. Your device will take only what it needs. It won't effect the life of your battery. Think about the charger you plugged into the wall socket. A wall socket can generate enough current to melt metal. Lower power draw is cooler but really just make sure the voltage rating matches and the amp rating isn't too low. USB should be 5 volts anyways. The big issue with amperage, can the charger handle the draw? Example would be a 3000watt car amp drawing power from a 18 gauge speaker wire. It might work but the wire will heat up since it isn't designed to carry that much current.
In short for USB the charger amperage can be higher than the device needs but probably no less than 1/2 the rated amps for the device.
As above, you could plug in a 200A charger and the phone will still only draw the same current as from a 2A charger.
The amount of current drawn by the device is firmware controlled to protect the battery from heat damage.
The stock charger is 1.5A so the phone must draw no more than that.
It's all about cables too. I have a 2 amp TomTom charger hooked up to a 3 metre long USB cable but it charges slower than the standard 'in the box' charger Sony supply at 1.5 amp.
More cable and wrong core rating = more energy lost or wasted. I actually had to ask a sparky about this one, but it's true. Cable length, rating and core make all the difference.
For instance.
If you hooked up a 3 amp charger (I had one for an old phone) to a cable that can only handle 1 amp then you will only get 1 amp into the device, probably melt your cable too over time.
Honestly, the best bet is to use as near as dammit to the original rating on the included in the box charger. Electricity is a funny thing, it can screw your phone up in ways only time and noting the battery life will show.

One of the big concerns I had with the proprietary Dash Charging system is whether I'd be able to use previously purchased power banks.
I've been testing my OP3 with the RAVPower 26800mAh powerbank along with the Anker USB-C to USB 2.0 cable.
The powerbank is capable of outputting 2.4a, which produces a quick charge on other devices.
On the OP3, I get between 30 and 57% charge / h (measured using the Battery Monitor Widget app), which is acceptable to me.
It's not Dash Charging speed, but it'll work in case you were wondering.
MI Charger
I have a MI 16,000 mAh portable charger with an output of 3.6A. I am getting a pretty awesome speed on 1 min per percent charge. After charge battery drain is lower compared dash charger.
quote from Android central
"For the first time, OnePlus is including a fast charging system on the OnePlus 3. Rather than go with another standard like Qualcomm's Quick Charge, OnePlus made its own "Dash Charge" system. Dash Charge promises a 60% charge on your OnePlus 3 in just 30 minutes, which is just as fast as any other system — the only catch here is you'll have to use the Dash Charger in the box and the included cable.
Your OnePlus 3 will charge just fine off of other chargers — whether they're Quick Charge 3.0, Nexus Rapid Charge or something else — but you just won't get Dash Charge speeds."
I have the oneplus power bank, I'll see how it charges using the cable that came with the phone.

Seemed like a good choice as outputting 3.6A would be good enough for me. Would you be able to point me a link where to purchase it from? Many thanks.
are you sure the 3.6a isnt a maximum of all the ports on the bank?
usually if they have multiple ports they say a maximum load for all being X, but I've only ever seen a maximum amperage of 2.4a on a port (few and far between) most 2.1a as stated per port.
even then they charge my OP3 at 1.2a using oneplus's cable, same as my s5 beforehand.
there is a great app on the store called Ampere which tells you your current charging/discharging amps

You can use OPPO VOOC Powerbank,
It charge as fast as at least 3.5A
It would not be charging at 3+amp
Unless your using a dash charger your never going to be able to charge over 2amp using any other charger

No offense but this is a flawed theory, did you forget what site you're on? That's what development is for, to boldy go where no one has gone before, so contrary to your belief, I'm sure its possible, can and will happen.
OP3 is only able to charge at 1.5A max with everything except the dash charger and cable, from my tests.

No it is not a flawed theory. The phone does not have the quick charging components in the phone but instead in the charger and cable. Only VOOC and DASH chargers will quick charge this phone. It's not theory it's fact. Anyways fast charging does deteriorate the battery a bit faster than normal charging so it's not good to use it all the time

You said with conviction that "the phone will 'NEVER' take more [than] 2 amp unless its a dash charger"
The VOOC charger is in fact 'not' a dash charger and it charges above 2 amps. So very simply, your postulation is wrong. I took notice that you quickly changed your stance but forgot how convinced you seemed to be.
All of this leads me to believe that there are other chargers even beyond the VOOc and the Dash that can/will fast charge the One plus 3
What's the easiest way to test what amperage a non-Dash charger is charging at? I'm curious to know if some of my Quick Charge adapters will provide 2.4A. I've only done a very brief test with my QC3 car charger, but it gave me 3% in about 4 minutes. That's about what I was getting on a QC2.0 phone, and that's perfectly acceptable in my books.

Huh? that's my first comment lol and VOOC and DASH are exactly the same technology and have their specific patent. As far as I know, it will only charge with those specific chargers since it is not only the charging brick holding some proprietary charging solution but also the cable. I have a USB-C cable that can withstand over 4A but will not work even when plugged to the DASH charger. Now yes there may be a charger that quick charges this phone but it'd be very unlikely that it does exist since the cable and brick would have to have the exact specifications as the DASH/VOOC chargers.

Same question. Really interested in the Oneplus Power Bank charging results. Please.
Everything I can find says that the only way we can "quick" charge is with the official OP Dash charger?
anything else we use will only do normal/slow charge?
As far as I know, this is correct. Dash Charge and Quick Charge are entirely different technologies that are used to accomplish a similar goal.
I believe that you can still use the QC charger, but as a normal charger. Just like Dash Charger when plug other phone in, it just turn into normal charger. But there is a potential problem here, Dash Charge works by pumping a lot of amps and keep the voltage the same, while Quick Charge doing it vise-versa, and QC is a technology develop by Qualcomm, meaning the SoC itself in the OP3/3T would support it, it just the rest of the hardware do not. If for whatever reason, the QC charger still provide more voltage than 5V, it could damage the phone. I don't know what is the max voltage the 3T can take before it get damage. If you want an official answer, get it from OP.
USB C plugs will work from what I've read, but nothing will quick charge but the Dash chargers--just normal chargers. Which is fine for me honestly, I use a regular charger at home (overnight) and keep the dash charger with me for work/etc where I need to pump juice faster.
That's dumb....I was hoping for quick charge 3.0 support plus dash charging. GAH! I might get a dash car charger then....I use my phone a lot. I like being able to charge fast while I use GPS. I use GPS a ton. And my new portable charger....QC 3.0.... That part of it is useless now.... grrrrr, but is this verified?
Maybe we all should contact Anker, and ask for Dash Charge support. What I very want is the multi ports car charger with at least one Dash Charge. But such charger do not exist anywhere.

Would love to see some 3rd party support.. in principle the idea of moving this function outside the phone seems appealing... but I hate only having 1 vendor to buy from... and I'm not even clear.. can I use the Dash charger to charge my non-OP devices? (ie. reducing the # of gizmos I have to travel with).

Yes but it won't "dash" charge them.
I asked the same sort of question here: http://forum.xda-developers.com/showpost.php?p=69856748&postcount=5
I've been using an anker QC 3.0 charger on the OP3T and it charges fine.
it doesn't get hot, doesn't say it's fast charging but it seems to charge at a reasonable rate nonetheless.

Thanks for that.
I'm interested in knowing if the voltage/amps/whatever are going to mess with the OPO battery that's not rated for the Q3.0.
Does anyone know if USB-PD charging would on the 3T? I ask this because as a nexus 6P user i have a number of charging accessories, and USB-PD is baked into the USB-C standard. So logic would dictate assuming the 3T conforms to the standard it should be able to charge at 5V 3A, which would be slower than dash charge, but quicker than the average charger.
Have a good one!
I have a 7 port anker usb3 hub that has 2 charging ports and a 2amp 12v wall wart. It charges just as fast as the OP3T charger. Full charge from 50% after work in under an hour.

I have an old quick charge 2.0 car and wall charger. I know they won't work with dash but I'm just double checking to make sure they're safe and won't damage my OP3T. Seeing as how the phone accepts 4a (I think) I'm pretty sure 2.4 in will be fine. Thanks in advance!
same Q, I have a QC 2.0 and normal charger, not sure if putting 2.0 or normal charge apart from the dash charge?
It's be ok to use lower rated charger (lower amperes). Any charger that is rated 4.0A and below should be fine. The most important thing is your usb cable should support the amps it is transferring. Make sure they are rated 2.0A and above.

If I am not mistaken, most of the newer usb cables are rated at 2.1-2.4A for charging. But if you want to be safe I would suggest you take notice of what the cables are rated at. For me personally, I always follow the rules of not using lower rated cables on higher rated input.
Any high quality charger will work just fine with OnePlus, although Dash Charge will turn on ONLY will OnePlus/OPPO dash charger and official USB cable. So you are limited to lower (non dash charge) speed.
QC 1/2/3, Turbo charge, Super charge, Dash charge.. adapters are safe to use with any phone, fast charging will not engage if the phone doesnt support it.
I recommend checking this spreadsheet: https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/edit#gid=0
Cool beans, sounds like I'm good to go. I'm using whatever cable the charger came with and a USB C adapter from Aukey. Works just fine! Not really too concerned about dash charge since it's sitting bedside or in the car for road trips. Thanks!
so just curious if i use a regular quick charge charger it will charge but at lower rate then dash charge

Yep. The only way to get dash charge is to have a dash charger and a OPO cable. They do the conversion in the charger and push 4a to the phone vs quick charge which depends on the phone to do the step up. You'll basically be charging at 2.4a or whatever your quick charge puts out.
