What's the side effect of using 2A output powerbank on the cellphone ?
From my experience, the output of cellphone adaptor usually between 500mAh-1Ah. Well, except phone with bigger screen (which i don't have).
What i notice is, the back of the phone are usually hotter compare if i charge my phone using phone adaptor or via usb.
I am kinda worry with this excess heat. Heat is not good for electric components.
It will shorten the lifetime of the battery

Seriously ?
Yes, if the phone is not designed for 2A

What about a phone that's designed for 750mAh and it's being charge with 1.2A powerbank ? Since the common minimum powerbank output are 1.2A.
Even that would be harmful there are 500mA powerbanks available which would be ok

I see. Thank you.
What about the opposite. 1.5A capable cellphone that's being charge with 750mAh charger ?
I think it would be fine. Just the time it needs to charge the phone is longer. What do you think ?
That would be perfectly ok, you're right it just takes longer to charhe

it does not work with my touchpad (HP). If i not charge with 2A output is no charge

Guys can someone tell me a good charger for my i9000. My original charger was bricked and now im using chines charger but it get lot of time to charge...
If someone help me i definitely HIT THANKS....
Buy an original charger.

You just need one with a higher output current. I forgot what current the OEM one has, but you want one that has an equal or higher current output. Don't worry about overcharging your phone. It has a chip that limits the maximum current it can receive.
Hello,
the caracteristic of original are: 5V - 0.7A
But some china's power supply marked 1A rely deliver less...
If you can buy an original!

Yeah, if you buy a no-name Chinese USB supply then you either get your phone plugged straight into the mains or the circuits and components of nightmares.

As far as safety, current doesn't matter. At 500mA you'll be charging pretty slowly though.
i use 2A charger from TomTom and working fine even with working GPS navigation and still can charge to 100%.

hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks
In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.
I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.
Go here to find out how to test your charging rate:

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".

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.
Samsung offers two wireless charging pads. One is mini and the other is standard size. Is it just the size that is the difference? Does one charge faster than the other?

It looks like the mini only does 1amp charging while the standard does 2amp charging. In short, the standard will charge your phone faster.

Where did you get that info from? In the description of the mini one it clearly states is comes with a 2A charger!
My understanding is that the mini is a new model released with the S5 whereas the other has been around for at least a year now.
Even if it comes with a 2A charger it only charges at 1amp. It's a limitation of wireless charging

I guess that sorta makes sense. I figured I'd use it more like drop my phone down to charge up a bit real quick before heading back out the door. Kind of a busy life style type thing.

The S5 has more than 2 points of contact for the wireless charging back. Not sure if it is for nfc, but maybe the doubled the charging capabilities by having two separate charging coils?
Edit: This is my first post is 5 years, I feel like a lurker.
The power of pad doesn't matter, the coil from the back of the case is the charging source. So for s4 note 3 it's 650 mamps and the new one for s5 is 700 mamps( if i spoted right in the pictures). The difference is in aspect and size only.

Are they up to 1A now? Last I checked, there wasn't a wireless charger anywhere that charged faster than 850mAh. Which is only 30% as fast as the USB 3.0 charging of 2500mAh.

1amp is theoretical charging speed.
Just like how the phone stock charger is 2amps, it will max out at around 1.8 amps

Here is a review of it
http://unleashthephones.com/2013/01/26/nokia-fatboy-wireless-charging-pillow-review/
Get them while they last!!
I have three wireless chargers. The small original Samsung, one Nillkin and a noname. I am using the original charging back from Samsung. I am very happy with the small original Samsung charger. The S5 gets much less warm than with the both others and it stops charging at 100%.
I had it on the Nillkin over night and the next day when it has been at nearly 100% already in the evening it was extrem hot at the morning and still charging but it showed 100% but not the full message at all. Very suspicious. With the noname I very often have the wireless charging detected message when it comes over 9x% so it looks as if the charger often "looses the connection" to the wireless charging back cover.
The original small Samsung charger says 5,3V and 2A on the back and it loads at maximum wireless power with the original back cover and the original power supply. For me this is the best combination. The only thing is, that you cannot use the S5 very well while charging because of the small charging pad. I most time take the charging pad with the S5 in one hand so it cannot tilt.

3 coils vs 1 coil.
3 coils is better with cases and easier to place the phone on it.

Both samsung charger are 1 coil.
3 coil offer a wide surface detection, but does not mean it's better that a single coil charger.

Length of dc wire will lead to voltage drop. Lower voltage means the unit will draw more amps to get the same wattage of power. If anyone needs a longer cable make sure it's not cheap and that it uses a heavier gauge USB cable. Unless you are fan of heat in both your charger and phone.

Yes, but we are talking a foot or two at most here; the voltage drop would be inconsequential.
