I bought a portable charger/power bank, 6000mAh, 5.3V 1000mA
but i just found that my charger (EP800) has 5V, 850 mA
I read it somewhere that using a higher amperage charger should be just fine since my phone will still only use as much amperage as it is designed for, and using a higher voltage could possibly fry my battery.
But my portable charger is only 0,3V higher, is it ok? how bad can it goes?
do batteries have any tolerance of using higher voltage?

I bought my G2X used and it didn't come with an AC charger. I've been using another charger I have from a LG phone (STA-U12WD) that is 5.1V and 0.7A. Was looking for a replacement and I read on an Amazon review that the original charger is a STA-U13WV 4.8V and 1A.
Can someone check their charger for me? Thanks.
You'll want both a high amperage and high voltage. Look for a 5 volt (or 5.1) and 1 amp charger.
Think of it like a water hose. Voltage is the pressure, amperage is the width of the hose. So higher width and higher pressure gets the most water. Also note that lowering the width of the hose increases the pressure.

hey redmonke, do you own the original charger? Can you check the model #?
and if you recommend a charger with higher amperage or voltage what are the limits?

I have the original charger that came with my T-Mobile G2x:
Model #: STA-U13WV, Output 4.8v, 1.0a
In my car I use a 5 volt 2 amp charger (though I'm not sure if it's 5 volt split across 2 outputs or if it's for one output, I'll need to test when I get back from university) . Look for 5 volt 1 amp on Amazon with good reviews.
I currently use a cheap 5 volt 700mA charger and it's alright, though it's not the fastest.

thanks man!
I use an apple charger. I also have a charger that can charge a battery and has a USB output of 5.2v @ 800Mah. I'm a little concerned of the 5.2v, I don't want to use it and 6 months later my phone stops charging or worse.
Hello everyone,
So I have been trying to find the answer to what I am wondering but to no avail. I know that when using a charger that did not come with the phone it needs to have to same voltage to not hurt the battery, but I am unsure of the amps. I know for normal powering of things the charger needs to supply the same amount of amps or higher so that the item can pull enough power from the charger. However, phones do not need a certain amps to be powered by the charger. So I want to know if I can use any changer that has 5 volts, but varying amps. This is because I read that if you use a charger with lower amps it is better for the battery as it is not charging as fast increasing the life span of the battery, is this true?
Example: I have a LG G2 which uses a charger with 5V and 1.8A , but I want to use my nexus wireless charger that is 5V and 1.2A
Thanks for any assistance!
Already, I thought the Xperia Z charger felt weird. It stated 1.5 amps as the maximum output amperage. Also, for that amperage the phone seems to charge quite slow, especially when compared with four other USB charges, of 1 and 2.1 amps.
So, tonight I decided to take a multimeter to the charger(with my USB breakout cable) and the voltage measured just 4.90 volts(measured using a high quality multimeter). I was just wondering if someone else on this forum could take their charger (EP880 or your regional variant) and check their voltages, as a voltage below 5v seems quite unusual on USB spec chargers, and it seems odd that Sony would design a charger that would raise the voltage under load.
Tried many chargers to power my Raspberry Pi (notoriously picky with power units). Measured the voltage over the TP pins on the Pi. The voltages ranged from 5.00V (Nokia AC-50E) to 4.75V (Sony XZ charger). Only the Sony charger manages to power the Pi without reboots and crashes, despite the lower voltage.
Both the Nokia and the Sony are made in China by Salcomp. Both are rated 1.5A. I guess they are identical on the inside. I am now charging my XZ with the Nokia charger and running my Pi with the Sony charger.
E: The Sony charger never had any problems charging my phone.
I use a 5v and 2A power bank charger. it's a lot faster
USB is strictly 5.0 Volts with a absolute maximum of 5.5 Volts if I'm not mistaken but it is not the voltage that applies charge to any device. It's the amperage.
Official EP880 Charger has perfectly fine 5.02V but only charges with 1A and not as stated 1.5A

I have a bunch of USB wall chargers lying around. Some are 800mA, some 1A, some 1.4A, or 2A or more. As long as the voltage is the same, can higher amp output easily cause damage to a device's battery? Is there a general safe range to consider?

I've never had any issues using other chargers with my phone. However it is recommended to use chargers from named brands such as Samsung, HTC etc as these have been tested for the Battery Charging Specification 1.1 or above to work with other devices.
Will any chargers that supply higher volt / amp combinations charge faster than standard or does it need to support dash or warp charge? I don't necessarily need the warp charge but faster than my current op2 would be great.
Anyone? Does higher amperage equal faster charging or does it have to be warp charge compatible?
There's communication somewhere along the path that allows dash/warp charge to happen. A charger can supply a high enough amperage, but your phone may not be able to utilize it without communication from the charger/cable. I'm not exactly sure how/what the process is, but I know it's not as simple as using a high amperage charger.

Any USB-C power delivery charger will do a rapid charge, just not Warp.
