Will this overcharge an Android phone at 2.1 amps, and cause a the battery to bulge or fail early?

Batteries and charging systems in modern devices have overcharge protection that cuts off input power when the battery capacity is reached.

I have not had any problems at all with charging my Samsung Galaxy Nexus. And it charges as fast as my wall charger

With power supplies, the current (ampere) rating is the maximum rate the circuit can deliver, not how much flows at all times. Your device will only draw as much current as it is designed to draw, nothing more. A 1000A power supply wouldn't overcharge your phone, assuming the voltage is correct.

I charge my wife's Galaxy S3 and my Note 2 for over a year with no problem whatsoever. This is a well built and reliable charger.

Absolutely not. You cannot possibly "push" current into a lithium-based battery. As long as you do not exceed the voltage (which is USB standard), all you care about is having enough current capability - no worry about too much.

I wish I could answer you - I'm not sure if it will do that. It does charge my iPhone and it hasn't casued any problems with it.

according to their website: "reVOLT c2 includes smart circuitry so that you won't fry your iPhone or iPod."

I don't think it will overheat, but it will "push" the battery more like a quick charge versus a trickle charge that the 1 amp would give. Over time, trickle charging will let your battery last longer. Push charging a few times won't impact most batteries. Also, the charger is well labeled. Hope this helps.

I have the GS3 which should charge OK on even the 1 amp port. I looked up the Motorola and see it has a 2000 mAh battery. Assuming a typical charge rate for that size cell phone battery, my gut feeling is that it would work OK. I would be surprised if it did not. I can't say for sure without more research. (I am assuming it's charge cord uses a normal large type A USB connector and your concern is just current draw.)

I doubt it would have a high enough power output to charge a battery that size... I would recommend against it.

charging this battery at 10 amps could harm the cells insideyou're better off to purchase a 2 amp trickle charger

I have not had an issue with this unit overheating. I have taken it from NYC to London, to Sri Lanka to Malaysia, and no problems. It works fine and charges my phone over and over again before having to recharge the Universal External Unit.

Yes, I use a battery tender etc a small charger that will not over charge any battery .

yes I don't see why it would not work, you should use a charge controller to prevent overcharging

To tell the truth, I am not sure, I only plugged the phone into the charger at bed time and when I got up in morning, I reached over and unplugged the charger and walked away without really looking at the phone. I never did have a problem with that type of Battery for that phone and have recently switched to newer style phones, but I keep this phone and battery for an emergency backup.

Dr. James M. Peterson - You are giving INCORRECT INFORMATION. Android post is 1.5a and not 1.0amps. Please change your information.

I don't know where you got this info, but the high capacity chargers for both devices are rated at 5VDC, 2.1A. So NO. And, if you charge at a faster rate the battery will fry!

Compare the amps required for your Android device with the amps supplied in the specifications for this product: http://bit.ly/1d3JTe7

Yes, this is a handy 2 amp charger that will prevent you from toasting this small battery. These batteries are easily damaged using higher amperagechargers.

No, if you over discharged the Lipo the charger will not charge if the voltage is too low.

Drew. There are two outputs with different amperages. 1 and 2.1 amps. Look at the picture above. If your phone charger is lower than 1.75 amps, I would use the 1 amp, just to be safe. If it is above that, it will charge faster on the 2.1 amp output.

No, Anything over a 5w panel and you want to run it through a charge controller first. You risk overcharging a battery (which will eventually kill it) if you don't, even 5w is pushing it unless its a 70ah+ size battery and it has a constant small draw from it (Like in a car where electronics are being run even when the car is off)

If a device requires 2 amps to charge, but you only supply 1 amp, it will not charge, and it, the device will strain the charger, possibly damaging it. This is dependent on the battery type, charging circuit etc.It's best to have more available current than needed.
