Can it work on the USB power, or is it only for charging?

It can and does work on the USB power. I leave it plugged in and turned on permanently as a wireless intercom from upstairs to downstairs.

This charger does not use the usb port, it uses the three spring loaded pins. That being said it should work, but there is always the possibility that with your usb port being damaged, that there is potential that the charging circuit may be shorted. So, no guarantees, but I would take the chance that it would work if it was me.

it gets power through USB. So, when you connect to a computer or a powered usb hub, it works. When you don't, you need to connect to the "charger box".

Yes, that's what it is supposed to do, but I have not used it yet. I just got it and charged it. I bought it because it has a regular plug rather than just a USB port.

Yes it's just a USB plug, so it should work fine...but honestly there are better chargers out there, this one doesn't charge that much

It should work just fine. USB voltage output is 5vdc. Amperage output will determine how long it takes to charge it up.

It is only the small socket that can charge. But I got an adaptor to convert the small socket to Standard USB socket.

Sure, as long as your USB supplies 5V power, which most USB do, it is worth a try, as its only taking power, it wont work if there is no power, and there wont be any damages which I encountered, though you try at your risk.

Yes, it works on any type of charger (AC or DC), as well as on any device with a USB port on it.

I recommend you try the 4 port USB 3.0. It requires no external power. However, charging devices through this port is not recommended. I have one and it has worked with everything I have tried in it.

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

Yes, if the USB Will fit any of your charging devices, it should work fine. I use it to connect my laptop, so I always using my computer to charge it.

It will charge when USB plugged in and have USB charge turned on in the E17's menu. Any USB port Mac or PC will work for data and power.

Nope !! I've tried that ! Lol. It only charges the battery and the USB whole plug in . If you want that capability you might as well buy a portable charger. I've boughten 2x 12$ from Amazon already. Great stuff.

It does work that way. Use the usb cable that comes with it and any usb adaptor and it will work. I prefer to use battery power rather than be tied to an electrical outlet.

I've used both a mini-usb to usb cable to any USB source and the proprietary. Any charger that give acceptable mini-usb power can work.

I have and it worked, don't know how it affects the charging of the Poweradd though.
