Can you charge/run this off of a USB battery once the internal battery runs out? Basically can this device run off of USB power?

This device does not charge using USB. It has a separate charge port. You can run and charge this device after internal battery has drain down using the charge port.

There is no USB power input on this unit. Power is supplied and the internal battery charged by the supplies power supply/plug. If your USB Battery had the appropriate plug adapter, I could see that working though. Hope this helps.

No sadly it can't be powered by USB. You have to either use the AC adapter or use 4 AA batteries.

Yes, there is a USB port on the device which will supply ample power to usb devices. I am using the 12 volt output to power a small Amateur Radio. (Approximately 2amps through the 12v output) The 5v USB out should handle everything, even tablets.

This unit runs on USB power. There is no need to plug this into an electric socket.

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.

If the device has a cable with a USB tip, the AbsolutePower will provide power and charge from an A/C outlet. It's not a backup battery source, though.

No it cannot be powered via USB, the USB is only used to transfer data from the Camcorder.

Yes, you can use it even if you unplug it from the wall as long as the internal battery is charged. Actually while plugged into a charger, it will not charge other devices such as a phone.

Recharges by USB. Which, ironically, is the same way it charges other things...Basically, if you have the ability to recharge it, you probably do not need it right then.

I only use it with external power, but I believe I recall reading that it can not be powered by USB.

No, the USB charges the battery and it won't work w/o battery. Although you can work with it while charging, but it is recommended not to do so, to increase the life of your battery.

I haven't tried charging another device from this but the operation does not need power supply. Simply plugging in to the USB port is sufficient to run all the functions.

The unit gets charged when attached to a computer. I assume that the internal battery will permanently fail someday, but mine has been through many recharge cycles while plugged into my computer and it still functions. I guess when mine stops working, away from a computer USB port, I will toss it and buy another.

If there is, it's by no means accessible to the average consumer. The clear answer is no.You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

You would have to crank it to provide power to the USB, but the flashlight on the device already provide light. It doesn't operate as a battery pack would. The cranking operation charges the battery to the flashlight and also outgoing power to the USB during the cranking. The flashlight works on its own without cranking, but the USB does not. Hope that makes sense.
