the stock opo charger outputs 2A-5V
i have another charger which is rated 5.2V-2A
i know that it's overvoltage can do harm (while extra amps can't), and i belive using it once would be negligable, but i ask myself if there could be any long-term effects to using it daily...
what do you think?
the phone adapts automatically, use the app "ampere" to see if he is carrying on this loaded voltage you use (do not recommend similar chargers)

HI everyone, hope thats the right forum
I have in my possession an iphone 4 charger, and since i dont have a dedicated G2X charger i was wondering if it is possible to charge the LG phone with Iphone charger?
thanks!
Well I thought iPhones use same charger as ipods which has a lot wider plug than an android charger. But if that's changed and it fits than plug it in and find out.

I don't see it working unless you have some sort of an adapter. The G2x uses a micro USB port, and the iPhone uses a proprietary port.
please see bellow what charger i have. just need to plud the USB cord in the charger, since it have USB input.
so, technically it should work, but will this affect the battery in the long run? i mean, maybe the voltage\current values are different.
If it is a USB adapter then it should conform to USB standards and would then work. I think most of the previous responses assumed you meant a charger with the iPhone tip.

The idea itself will not work, you can pick one up from Amazon or eBay for pretty cheap.

Actually it's likely it won't work. Compare the amps on the G2x charger vs. the iPhone one (and just about any other generic USB charger). All the one's I have are different, lower, and don't work with the G2x. One of them, for some odd reason, makes the touchscreen not work at all when plugged in.

That is not correct, iphone charger will work technically, however it will reduce your battery life over time due to iphone charger are 1amp while g2x charger is 0.7Amp. Amps must meet to properly charge at the pace selected by manufacturer and battery specs. Lower amp takes time to charge, higher amp will charge fast but will reduce life.

Mine is rate for 1AMP.

How does it even fit? The ports are totally different. Perhaps an adapter?

DON'T DO IT!!!! your phone will suddenly become just like everyone else's and you won't be able to do anything about it! your technology will become dumbed down, and you will becomea victim of conformity!
HEED MY WARNING!!!
Don't worry, using that iPhone charger/adapter won't turn your Android phone into an iPhone.
The iPhone charger/adapter is a 5 volt USB adapter, it will work. The battery will charge normally, there's a charge regulation circuit in the phone and protection circuitry in the battery which will ensure that the battery won't be screwed. I use a variety of USB power adapters which range in their current rating which is the maximum current the device is capable of supplying at the rated voltage (although the cheap adapters' output voltage decreases as the current output (load current) increases. The LG power adapter I have is rated at 4.8 Volts and 1 Ampere output. I use that, a USB port on my computer which is rated at 5 Volts and 1/2 Ampere (500 ma), and other 5V power adapters. I also use a variety of micro USB cables some of which are just for supplying power, not data, and they work too.

thanks for the informative reply Core Memory.
didnt think using iphone charger will turn my android into iphone
so, bottom line - it is safe to use that charger.
Thanks!!

Yes, it's totally safe. I've got a service manual for an LG phone which is substantially the same as the G2X and Optimus 2X which shows the battery charge circuitry. That circuitry regulates battery charging. Here's some more info regarding the battery:
90% = 4.05V +/- 0.05V
60% = 3.83V ditto
30% = 3.72V ditto
10% = 3.64V ditto
OFF = 3.42V
The battery voltage decreases according to the load current (milliamps) over a period of time. The higher the load current during a specific period of time, the quicker the battery voltage decreases; that's why it is important to have everything except the cell radio and the operating system off when the phone is in standby. There will be some background processes, etc., which are necessary too. Bluetooth, GPS, and WiFi quickly drain the battery. Automatic updating should be turned off always. If you're not expecting any calls, turn the phone off. Setup your phone to reroute received phone calls to your home or work phone, if the call is important they will leave a message, then pick up the messages at your convenience. Use a ROM and kernel which are known to have good battery life.
ive been useing the iphone dock to charge my g2x and it works fine lol no issue
I have note2 right now which have to go. But I'll keep my office charger which is 2A.
Can I safely use it to charge n5?
Sent from SGH-i317m
Using chargers with a high power (A) is no problem, the phone will not "take" more than it needs.
Sorry for the poor english ^^
The issue is if charging IC can handle 2A current or not. I dying wanna fry it lol
I would think it should not be an issue while 2A ICs are widely used in our days, but "better be safe then sorry".

I charge mine with my xz charger 1.5a no problem
The charging block that comes with the Nexus 5 is 5.0 volt, 1.2 amp.

While AFAIK there's no 1.5A ICs, than its 99% safe to say they using 2A nominal IC.
Thanks guys

If using a different charger was a problem they would have made the connection something other than micro USB.

Not really. Charging current depends on IC installed, not the connector itself.

From what I understand, you could use a 10A charger and still be fine. The handset will not take any more than it needs. Basically, the charger doesn't push current, the phone pulls it.

Thats correct and nothing else. No way to destroy a phone with too much A because it just takes as much it needs. The 2A on an charger is just the maximum power output. It is physical impossible to PUSH the ampere in the device.
Moved from general sorry
I just bought a Anker 24W / 4.8A Dual-Port Car Charger. I bought this to replace a cheap $2 charger that I did not want to use on my nexus 5
I just tested the anker charger and it puts out 5.24v-5.29v. I know that does not sound like much but all my other chargers AC wallwarts, and even the cheap $2 car charger all put out 4.95v-5.02v.
Should I go a head and use this anker car charger or should I return it? Thanks.
That's just how much the charge puts out. The phone may not accept that much input.

Typically there is a boost/buck or other relatively efficient voltage regulator in the phones that manages the battery charging, so the 5% "over-voltage" that you are seeing shouldn't be an issue.
I'm guessing you measured that with no load -- most wall-warts run a little high without load, and then a little low at full load, so they can claim good regulation (+/-5%, for example) and a high current capacity. The change is due to internal resistance of the supply, something that you can compensate for, but can't ever get rid of.

Only when talking current. Voltage is completely different.

No I measured with a load. I have a voltage current usb meter.

I just did another test. This time with my phone almost at 95% full. I got 5.33v while sucking down 332mha.
Im sending it back. I tested every charger brick and several other devices in my home. nothing came even remotely close to 5.3v
USB specs are 5.0v +-0.25% so I should see no more then 5.25v.
If I'm not mistaken the brick says 1.5 outout and my htc one charger had 1. Is it gonna charge faster or something? This could be a dumb question.

Yeah its a 1.5 and it it should charge faster
Sent from my HTC6525LVW using xda app-developers app
Yes and the new bundled charger supports QuickCharge 1.0
is there any downside to using a charger that outputs more than 1.5a?
no downside to too many, just too few. more amperage, higher possible current (at the same voltage)

Is there a permanent downside to using one with too few amps? Or just the obvious one that the phone won't charge fast (if at all)

No, it will just be less current. In some cases this may mean the phone won't charge at all (for example, a low current power adapter while you are using a hotspot would most likely still drain your battery slowly). Low current won't cause damage but your phone may take longer to be able to turn on when it fully depletes and has to recharge.
Real world example: my phone ran out of battery while I was in my car and I tried to use a cigarette port charger and then immediately power it back on as I had done numerous times at home with the A/C adapter. Unfortunately the car adapter was lower current so it took about 10 minutes for my phone to charge back to a point where it would power on. During this time I was blindly driving around haha.
Hi,
The Nexus 5 charger that included in the box had 5v 1.2A power output. Is it okay to use charger or power bank with higher power output such as 5v 2.1A or 5v 3.6A. Will it cause any harm to our phone?
Thank in advance.
2.1 will be fine. Nexus 5 is physically limited to I think 1.5 so 2.1 will only deliver 1.5
It is possible to burn out the circuit with too high a rating but I don't know if 3.6 would be enough. I wouldn't risk it though
Holy crap that is a lot of voltage. If it does work, your battery capacity would gradually worsen faster than a trickle charge. I purposely use a .5 A charger for overnight when I sleep because it helps the battery last longer over time.

Since the nexus 5 is limited internally to a specific current capability, a higher amp charger will do nothing past what its rated at. Heck, you can even get a 10 amp charger and still be fine. Your device will inly use what it needs.
