Hey guys, I am planning to buy a new charger for my phone.
I am confused between 1A and 2A charger.
Will charging my phone with a 2A charger have any effect on the battery life, Heard from someone that the 2A charger will kill my battery, Is it true?
Please advice!
thanking in advance :good:

It's not true. You may use a charger with 2A output but it's really enough 1A for One V. 2A charger might be useful if you will decide to use it for other devices that requires more powerful output.
No way you can reach 1A power consumption on this device, even if using navigation, bluetooth and streaming simultaneously at the brightest screen setting. And even if you plug a 2A charger, it will still draw just as much as it needs (max around 0.5A), so don't re-invent the wheel and use a factory spec charger - 1A.

Hi,
I've lost my charger, and I don't know if I can charge it with a charger with 5v - 1A or not, what I do know is that charging with USB is 5v - 500mA.
What's the power of the SE Arc original charger?
On the charger it says output 5V 1A
Is that what your looking for
It's Exactelly what I'm looking for thank you very much
The original SE charger for the arc is the GreenHeart charger EP800. It has got an output of 5V; 850mA.
As far as I know, there's no SE charger with an output of 1A. I've seen chargers with 500mA, 700mA and the 850mA.
My charger got fried during a power surge while holidaying in India so after asking around on the forum, I bought a Nokia AC-10N charger with an output of 5V, 1200mA. I've been using it without any problems. Pretty happy with it. Charges the phone much faster.
Thank you, that helps very much, but I heared charging the phone with higher voltage or higher Amperage can charge it faster, but it lowers the battery life on the long terme, it's appreciated to charge it with lower power in order to preserve battery life

Totally true on all counts. You can really use ANY usb charger to charge your Arc, but the higher the mA the faster it will charge. And the higher the mA, the less overall life your battery will have. If it's normally supposed to be good for 5000 recharges, it might drop to 4000 recharges (just numbers pulled out of thin air).
The "Normal" standard for USB power is 0.5A (or 500mA). The iPad for example uses 1.0A, or twice as much as standard. Now in the iPad's case, it refuses to charge with anything less. I don't know if that's true for the Arc or not...if so, and the SE charger is rated at 850mA, then that's probably as low as you'd want to go just to be on the safe side.
Personally, I'm willing to use the iPad's charger and charge a bit faster for a bit lower useful battery lifetime. A new battery I can buy....time spent waiting for my phone to be charged I can't get back
The amperage rating on a charger defines the maximum current the charger is capable of supplying. A 1A charger doesnt force 1A down the throat of whatever's connected to it, if you connect something can only manage to pull a maximum of 500mA then it will only get 500mA.
Consumer power supplies are generally constant voltage. E.g. a 5V charger will supply 5V to anything connected to it. The amount of current that the device will draw at 5V is the amount it was designed to draw, up to the limit that the charger can supply. If the charger cant supply enough, generally you just get slower charging (though some poorly designed devices will just refuse to charge at all). What *will* tend to destroy your device quickly is a voltage mismatch, e.g. connecting a 5V phone to a 12V charger.
You can get constant current power supplies. These ramp up the voltage in order to force the required current out regardless of what's attached to it (even if that's a human being). They are scary.

Exactelly what I was thinking, thanks.
Now I think I can charge my Arc with 1A without any problem, since it's gonna take only 850 mA from it
i am thinking about if my E975 is limited when it comes to how many amps it can charge with bcs i recently brought a 2A charger also tried it out on my Google Nexus 7 2013 and i don't feel like it charges that much faster then my original LG charger with a 3meter flat OEM kable.
the charger i brought is said to charge with 2A while the original LG is only 1.2A shouldn't i be feeling a difference?

No, you shouldn't. You can plug it into a 10 Amp charger, but the phone will only draw the amount it needs. Remember, it's not the charger pushing the current to the phone, it's the phone pulling it from the charger. The charging current is determined by the phone - each Li-Ion or Li-Po battery has a controller curcuit. The important thing is for a charger to be able to provide what a device wants to draw - otherwise, it would charge slowly, or not at all. So, a charger should be rated for not less than X Amp. More amp rating won't hurt, but it won't increase the actual current...
oh this is very useful. I also had the same question.
mine came with a 750mA (.75A) charger. As I left my charger at home during the holidays, I had to make due with one that I bought from a nearby tech store. I was very happy with the charger that I bought as it charges my phone really fast. I found out that my new charger was also a 2A model.
so I guess, in my experience, I noticed a big improvement in charging speeds comparing the 750mA with the new 2A charger. But I guess coming from a 1.2A charger, it only makes little difference.
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.
I will buy a power bank of TP-Link 10400 capacity and 2A output. Is the output any good for our device or the power bank has to be 3A like the charger ?
It will charge your phone, it just won't charge it quite as quickly as the original charger does.

Anything will charge it, but the output will dictate how long it will take.
A computer only outputs about 450mA (0.450A) but takes ages in doing so.
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.
