Is there any problem in not using the travel adapter for appropriate output (1.8A, 5V) instead directly charging with USB cable to an output of 2.1A, 5V?
Yes, you can use an adapter that puts out 5 Volts at 2.1 amps instead of the LG charger that came with the phone.

Will the extra Ampere(ie. 2.1A) cause any battery burning or damage? I'm using the dual SIM variant that doesn't support Quick Charging. Model Number: H818P.
No, the phone will only draw as much current as it needs. The power supply can't force more current through than the phone wants to accept.

What if as a contradictory case I'm plugging it to an output of just 1A, 5V?

The phone will charge at a much slower rate at 1A. It's even possible that the phone will slowly discharge at 1A, especially if you are using/playing with the phone.

need a quick help here. i accidentally left my charger at work overnight, and someone decided that its his/her's now ....ive searched around and cant find place to buy the original charger that came with the m8. HTC's website doesnt have it. amazon doesnt. even ebay dont carry it.
i need of a charger. currently using a LG G2 charger thats rated 1.8a 5v .....but with a super slow cable.
is the LG charger okay to use? will it damage my m8 in the long run?
i am also buying this cable on amazon. buy or dont buy?

yes, i know there is a quickcharge 2.0 coming out. seeing as the cable is only $5 ...im thinking it will do for now.
thanks in advance
HTC charger outputs 5V and 1.5A. As long as output voltage is same, you can use different chargers. Ampere value just affects charging time. Higher ampere means faster charge. In long term, it can shorten your battery's life, but I don't think 0.3A can cause an observable affect

I use all sorts of chargers. They are pretty much standard now as far as micro usb goes. As said some are higher rated some are lower. I don't think there is any that will damage the phone as long as its designed for charging and is 5v.
I too use multiple chargers and cables and the only issue I've had is a double length cable that works for charging but won't allow connections to the pc
XDA app on m8 running venom
I charger capable of delivering more current will not damage your phone since the phone won't draw more current than it wants.
Hello Everyone
I'm little curious
Just wanted to ask that is it safe to use a 2.1A charger on 1.8A phone ?
Because most of the car chargers come with either 1A or 2.1A..
Since our G3's comes with a 1.8A chargers..
Is extra 0.3A too high ?
Will it affect the battery life ?
I was reading some articles but didn't get the answer :silly:
On the other hand I also read that..
Too low current (using a 1Amp charger for a tablet designed to charge with 2 Amp charger) causes less damage, but slows down the charging cycle which may deteriorate the battery charging levels or performance in the long run.

Did anyone notice from his/her personal experience ?
So the question is which is safe-er ?
To use 1A or 2.1A charger when 1.8A is not available ?
it's not a problem, cause it s the phone that dictate the charging current ( that is in Ampere and not milliAmpere , 2.1A = 2100mA)

Ops !
typing mistake :silly:
I have used a range of different ones 0.5, 1, 1.2, 1.5, 1.8, 2.0, 2.1 max, different brands too) for my G3 for the past 6 months, no detectable adverse effect on phone or battery.

Charger is not a current source, it's voltage one. Meaning voltage will be 5 volts, and current will change depending on load.
The current is dictated by resistance of charger, phone and cable. 2.1 A marking simply means that it won't output more than that regardless of resistance.
And yeah, phones do regulate their charging current, so it's absolutely safe to use any charger.
Plus...if battery dies...it is replaceable.
What about ..
Too much current, like using a 2 Amp charger on a phone which is designed for 0.8 Amp or 1 Amp charging may heat up the battery, may hurt the circuitry or may make it misbehave because of static charge build up.

Well, either the quote is more than 3 years old, or the one who wrote this is an idiot.
read:
https://en.wikipedia.org/wiki/Battery_charger#Mobile_phone_charger
https://en.wikipedia.org/wiki/Power_supply#AC-to-DC_supply
basically, the charger is an AC-DC converter. Charging current is determined by phone, but it can't exceed the maximum current specified by charger's manufacturer - mainly because trying to draw more current from it will make voltage drop below acceptable level.
Samsung phones have a user-controllable charger chip, which is able to drop the current till voltage stabilizes, etc etc etc. I'm 146% sure that other manufacturers use something like that too.
So the G4 comes supplied with a 1.8A output charger, and I am wondering whether it is okay to use another charger I have, which has a 2.1A output? As in will it damage the battery over time?
I have heard the G4 supports quick charging so I'm guessing in that case it would be okay.
Thanks in advance.
It's fine. The phone will charge at whatever current it deems safe, even if you had a 100A supply available.

Would it charge faster?
Maybe a little.
I get about 1600mA with the stock charger. And about 1900mA with my Quick Charge 2.0 charger, which can provide the equivalent of >2.1A. I don't have any good-quality normal 2.1A chargers available to try.
So the largest benefit you could see would be about 20%, if the phone charged as quickly as it does from a QC 2.0 charger. I doubt it would charge that quickly, personally.

The default charger for my Xperia M shows an output current of 850mA. My doubt is whether it's safe to charge my phone(Xperia M) from the 2.1A output port of a power bank? Or should I only opt for a power bank with a 1A output port.
PS: The voltage rating is the same so no issues with that.
Do whatever you want, but you should avoid using the 2.1A port, since it can make the battery wear out faster.

So, that means I should go for a power bank which has at least one port with 1A rating right?
One of the power banks that I was considering had 2.1A rating for both output ports. I'll avoid that then.

Yes, you should go for it.
1 Amp would be good. 2 amp no problem

1 amp/2amp. It doesnt make a difference according to Sony Xperia M. There is a return line in usb port, like in every other electronic devices. The phone will use the amp it needs, and returns the remaining current to power bank itself. An optimal requirement of our device is 1amp. Even if you provide 2 amp the phone will return the remaining amp to power bank., So dont worry about battery wear and tear.
Recommended Stable and safe chargers (according to my study)
MTT Dual port 2.1 amp charger
MTT airpower 15000 mah.
These charger and power bank is safe in all way..stable current.

OK I'll go for a dual output one(1A, 2.1A) for the time being.
Hello xda,
I've recently bought a 2.4A 5V charger for my tablet. I don't know the current ratings for this tablet. So is it safe to use the 2.4A output of the charger? It has the original battery on it.
I use one regularly.

I use one all the time as otherwise it takes 'forever' to charge my P605. It still takes quite awhile but probably two times faster than a 1A charger. I think the Note limits the input voltage to some extent.

Thank you for your reply. I've measured the currents while charging my tablet. When I use 2.4A output it is drawing around 300mA current which is nonsense. I think there is a compatibility problem with the adapter and the tablet. However when I use the 1A output it directly draws a stable 1A current. Now I am using this output to charge my phone and my phone's adapter to charge my tablet, which gives 1.3A. My phone is note 2.
So my problem is solved. Again thank you for replying

I'm using a RaVpower iSmart which has a 5V/2.4A and a 5V/3.0A port. the 3A port is very slow to charge but the iSmart 2.4A charges faster. I guess it may be the charger type, sensing/negotiating the maximum battery charge rate correctly could be the difference. Wish I had a way to test that theory.
