Hi,It doesn't matter which jack you use either the 1.0A or 2.1A. The USB jack marked 2.1A (A) is for Apple products so you can charge an iphone or ipad. Kind regards, Terry 877-268-1235 x304

Hypothetically yes. The only thing I can think of that might be an issue would insufficient power from the adapter, but you shouldn't have an issue.

Theres a 1A and 2.1A usb on the side, I use the 2.1 and find that my droid charges up pretty fast

I suspect it would have no issue with that. It will sustain a normal phone, and the voltage is the same. But, you do have to crank it to charge. It doesn't charge from the onboard battery or the solar cell, both of those are just for the radio and its functions.

No. The charger would be damaged if your device needed 2 amps and the charger only provided 1 amp. The 2 amp rating means it could charge 2, 1 amp devices at the same time. I've used it many times without issue on a variety of devices.

Yes. 2 PAC. Just a heads up.check the AH. 3.0 are the big battery's. the thinner ones have about half the power and don't last as long.

Its meant for 110 & i've only used 110 but it could only hand 2 smartphones/tablets at a time. So I WOULD NOT buy it.

I use lots of non oem chargers with various mA ratings but mine are all 5.0v. I would imagine that the phone has a regulator since chargers may naturally vary by a few tenths of a volt, if you use it with your stock battery without issues you would probably be ok.

No this is a classic no frills old school phone. No external power source is needed. Perfect for power outages as long as the phone lines are not down somewhere on you're grid.

It's unlikely to harm being below the amps rated, but it may not charge properly or give a false reading of being charged when it is not fully charged, but even this is not for sure. But if the charger sends 2 amps to a device that is only rates for 1 amp, then yes, bye-bye device.

I have used the 2.1 amp port to charge my Blackberry cell phone and it is really quick. However, it can really damage the battery if left on it too long. I take it off after about half an hour and so far I haven't had any problems.

I would first check the amp that is recommended for your phone ie 1.0, 1.5 amp...The android provide 1 amp.

4.2 is not USB spec, sounds like a typo. Charge the battery with your phones original charger and it will be fine. People experience problems with aftermarket chargers because they are made poorly and run outside of standard USB spec. Unless you are using a damaged charger, any AC wall USB charging block from a reputable manufacturer (samsung, apple, etc) should be fine. Your phone will not pull more current than it can handle (unless it is already damaged at which point it doesn't matter what charger you use) due to Ohms law, the only danger is connecting it to something with too high a voltage.

I believe the newer phones may require more power, you may need to unplug some other devices that are also drawing power. Also, plugging in the adapter and into a computer will give you added power.

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, this probably won't work, as the usb hub will not provide enough power to the phone.
