[Q] Can blackberry charger be used on milestone?

This may be a dumb question. I read in another thread that a charger with less current output may not harm a phone, but it will just take longer to charge. I'm wondering if a blackberry charger rated at 5.0V, 750mAh can work safely on the milestone? The original milestone charger is rated at 5.1V, 850mAh. I haven't tried it yet though...

I use my girlfriend's charger to charge my Milestone all the time. The way I see it, so long as the output is not greater than the Motorola-shipped one, then I should be fine.

I used a friend's Nokia charger multiple times - and it's rated 5V and 1200mA - no damage either.
The Milestone is designed to be content with Moto's 850mA charger - so if a charger CAN deliver more - it doesn't mean the Milestone does receive more.
On the other hand - I did no longterm tests to see if the Milestone CAN charge quicker with a more powerful charger.
Long story short - as long as the charger doesn't exceed 5V (which will be hard to accomplish using an unmodified USB cable - you don't have to worry about anything.
If it fits -> plug it in ;-)

If it's a USB/micro-USB charger, it will work. The current rating on the charger is the maximum it's capable of supplying. It's up to the device how much of that will be drawn.

Well, I have a few experience with charges on my Milestone. In this case, it has no problem for you Milestone...but it will take more time to charge then other charger.

I have posted this before in another thread..
As long as its a USB-Port, you can charge everything that is charged via USB. They are all (basically) the same. Its like plugging your device into the USB-Port in you computer. You wouldnt worry about plugging something in there. Same applies to Car-Chargers.

My neighbor lost his n900 becouse he pluged his phone on a Car-Charger....he didn't saw that the Car-Charger is 12v....
In my option, it important to check the volts before plug it on your phone and yes, you need to worry about plugging something in there...

mh. 12v is very uncommon. Idk, at least here in Germany (more or less whole european union) you dont have to worry about voltages. There is even a EU-Law that all phone charges can be used for every phone (USB-Based).
Sorry i dont know about the situation in T&B.

Either the Charger was violating the USB specifications (if he used a USB cable) or it coincidental used the same plug as Nokia used for their old phones.

I think that is OK, I had used BlackBerry chargers, ZTE chargers and Alcatel.. Different specs, but works OK (some of them slower than others, but are OK).
I think that there is no problem with that, just take a look to charge a phone using the PC and micro usb data cable.. Every coputer give to you different voltages and amp, but always works!

Errrm, no.
USB always has to give 5V - more than that can cause serious damage.

The only problem with diffwrent chargers could be the current dofference, but with lower current capable chargers lile the motorola v8

Using different chargers question please

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.
Sent from my GT-N7100 using xda app-developers app

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.

Fast(er) AC Charger Recommendations

Greetings! I was wondering what is the maximum rated input current of the Xperia Z. There's no indication of it's rated input current anywhere on the phone. The supplied charger is rated at 1.5A and I was wondering if a higher amperage charger above 5V 1.5A (such as of those catered to tablets/ipad) would charge the battery at a faster rate before investing in one.
Anyone with any experience using a higher amperage charger on the Z could advice on any notable improvements in charging time as well.
Thanks!

Used a Nexus 7 charger rated at 2A and it charged fine with no detrimental effects. Charging time is about 1.5, hours from 10% to full.

While increasing the Amps will result into fast charging... the bad part is that it kills your battery life overall.

I've tried Sony charger rated output 1500mA
and Galaxy tab charger 2A
phone on, screen off
in 10 minutes charge, both added , just the same, 10% juice.
may try it longer next time.

Great findings! I guess it's safe to say that there is no notable reduction in charging times even with the provision of higher amperage chargers, and that the Xperia Z's power management IC can only take in 1500mA at max.

Charging at higher amperage would generate more heat and this increase in heat would degrade the battery cells at an increased rate, thus reducing the lifetime of the battery in the long run
Well unless you value your charging time (or loss of usable time) more than the cost of premature replacement of battery, then quick charging is for you. Personally, given a choice, I'd rather not charge at a higher current unless necessary, especially when time is the essence. (;

Erm I'm fairly sure that whatever amp you use the phone will only draw a set amount I used a 2500mah charger with my old phone for two years no difference in charging time nor degraded battery life or iverheating , just meant I had one charger for everything lol

That's correct, it's impossible to over-charge or charge too quickly a device by using a charger with a higher current rating than the original charger. Current flow is a RESULTING property of a particular voltage applied across a particular resistance. Applying too much voltage will usually be detrimental, but you cannot SUPPLY too much current. The device will draw as much as it needs unless it is limited by the charger's maximum current rating first.
I've been using an old Blackberry charger rated at much less than 1000mA. It might take a bit longer to charge, but I love the long, supple lead that comes with it.

Can someone explain me this...
My Xperia Z came with (1) Power plug-adapter with USB port + (2) USB to Micro-USB cable + (3) Docking station.
The (1) has Output = 1500 mA written on it, the (3) has 1800 mA on it.
Questions:
Can the USB cable transfer more than 500 mA? From reading USB page on Wiki, looks like it can do 1500 mA - 5000 mA when not transferring data so I should not worry about the cable?
What is the point of including a 1800 mA docking station + 1500 mA power plug? Does the station only charge at 1500 mA when connected with that plug or am I missing something?

The charging chip it self support higher current by default, but the manufacturer chooses the charger depending on different factors, design of the phone, capacity of the battery and also their stock chargers available... they will choose the best charger to match... in most cases it will be rated lower than what the charging chip is capable of...
the charging chip has it's limits also... using regular USB cables will only provides the standard current... I've used same amperage chargers as the orignal but with different cable and charging was slower... when I switched to the original cable charging was faster and had the same time as original charger ( same amperage )
When you use the original cable and higher current charger then you will have faster charging...
My Xperia arc came with socket charger rated at 950mA and a car charger rated at 1200mA... and the car charger is really faster but only when I use the original cable, when I used a longer cheap cable the charging was actually slower... even when I'm charging non-Sony devices ( like my Note 2 ) when I use original cable ( wether Samsung or Sony one ) charging is always faster... I don't know why it might be a way to protect the standard usb cable from over-current as the standard USB current is 500mA, so the charger will normally send the usual current unless the device requested higher current then it will negotiate with the charger to send higher current the original cables might have something like impedance between some pins so the phone will detect them as original then they will negotiate the charger to send higher current or the charger might actually use the other pins to send higher current but the phone will only use these pins when it detect the original cable... if not then it will not use these pins and will have regular 500mA charging... I've always faced this when dealing with other cables... now when I want longer cable I just use USB extension cable with the original cable and it will work !

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Can now make some docks/charging clips using sugru and a usb cable
Not sure why the dock would be rated at 1800, unless they've fitted it with some circuitry, a simple micro usb to prongs would do.
I charge mine using the adapter that came with my note tablet which is 2a and also with the 2a output of an external battery pack.

Yes, they're right to write the 1.8A there.
because, not all microUSB survive to deliver more than an amps. They maybe melt. especially the cheap one that have very small and loose contact area.
the pogo pins too... Not so easy deliver 1.8A with pogo pins...
that's why intel processor, have 1000+ pins, but almost 300pins are for power supply only (GND and VCC). Although the chip is only 1.25volts, but the current sometimes about a hundred amps (Core 2 Extreme, Core i7)

Wrong. If you connect a 2.1A supply, you'll see no difference.
Charging rate is set by the phone, as long as the power supply feeding it doesn't "brown out" under the load.
2.1A, 3.1A - doesn't matter, the phone will draw less (I'll need to drain my battery down a bit to determine how much less, it's often less than whatever the wall charger is rated.)
There is a possibility that when it sees voltage on the pogo pin connectors, it increases charge current to a different value than on AC via the USB port. The ext charger handling in the pm8921 driver is really convoluted and difficult to read.

[Q] Quick Charge 2.0 confusion

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.

@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand

Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.

Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.

I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people

Any good replacement charger?

Hello,
I lost the charger that came with my LG G2, and the genuine one costs quite a lot in my country,
So I wonder if there is anything I can buy on eBay that is safe and charges just as quickly?
(I need EU plug btw)
Thanks

i have both stock and this one

using original lg usb cable it charges the same as the original LG charger... and it has 2 ports for charging, which is only a bonus...
it's cheap, build quality is ok and it works well for me (i also use it to charge my tablet)
if you're in European Union - shipping is fast (it took 3-5 days for it to arrive from Cz to Croatia)
i also recommend this shop for other tech stuff, i already bought some hardware for my PC from that shop, and the quality of service (especially shipping) is great...

Try Ikea usb charger - nice choice for universal home charger
http://www.ikea.com/us/en/catalog/products/10291881/
It give 2.4mah for one usb port (for my device max ~1850mah)

Thank you!
By the way, if the stock charger was 1.8 amp (if I remember right), and I get a higher amp charger (2 amp for example), does the LG G2 know to lower the amp or, higher amp than what was intented might hurt the battery?

the one i recommended above (3.1 amp) automatically adjusts to connected device(s)...
or if you use a custom kernel like dorimanx' - you can manually adjust the current input (from 500mA to 2000mA) - i have it set on 1600mA and have no problem whatsoever...

Thanks, I have another question:
Will a quick charge 2.0 charger damage the LG G2 battery? Or it can work with it

Just an FYI, I bought a refurbished G2 recently and it came with a 5 volt 2 amp(2000mah) charger. I think you can get any generic charger that has those specs.
I tried a lower power one and as expected, it attempted to power up and shut off.

Belkin makes good one's...try them!

I used a p3 killawatt to measure the draw and the charger drew only about 1000 mah. So any charger that falls in that range should work.

Using genuine iphone charger with the usb for a while try it

Any good quality charger with at least 1.5A output current will do the job well. Tested, no issues.

Can't believe this thread is still alive and on top

So why they make the genuine charger 1.8A?

Thanks, but I wanted specific ones of high quality that you may know of

Did some further testing. With the phone powered off, the phone draws about 1700 mah or 1.7. So a 1.8 mah charger would be about the max of its capabilities. It also charges the phone in 2 hours.
With the phone turned on, I guess it charges at a slower rate.

Just look for a brand name with 1.5A - 2.0A current output. I'm using different chargers and they all produce similar results - Sony 1.5A charger from SRS X3 Bluetooth speaker; Samsung 2.0A charger from Galaxy Tab 4; the LG 1.8A one that came with the phone; etc. Charging time is about 2h on idle / screen off, as mentioned above.
