Does it have to be connected to a computer or can I just power it with a USB battery?

The Discription says "Plug in to Any USB 2.0/1.1 Interface". Hmmm! Is this just for Power?

Never heard of a USB battery. Mine didn't work when I first hooked it up to my computer. Found out it came with a bad cable. With another cable I had laying around it works extremely well. You have to have it hooked up to your USB port on your computer to power it and also to receive WI FI.

yes, the battery is required when connected to the computer. Just tested it to make sure.

It needs to be always connected. It runs on USB so you might be able to use one of those backup batteries with it

It requires a power source. You can use a BEC, or a (4) cell NiMH or NiCad battery (4.8v-6v)

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

It does not connect to the computer. It can be used with batteries or an AC adaptor

It needs to be plugged in to a usb socket to be powered. No on/off switch thus nothing is charged.

A USB is not necessary. It comes with a cord and can be plugged into an outlet, so you don't need batteries

It does include a USB cord, so if you have an adaptor for USB to an outlet (like lots of cell phones use) you can plug it in. Or, you can power it from USB on a computer.

It doesn't have a bettery or external power supply. Takes power from USB only.

You can charge it through a computer or buy an adaptor and plug it in the wall

Has to be connected to a computer or lap top via USB cable. Computer has to remain on the entire time. I would keep shopping if I were you. I liked it at first, but keeping the computer on all day/night is an energy waste and suddenly the USB connection will not work. Not happy with this product.

It does not require batteries, but does have to be attached to a USB port. This company offers a different version which is what you are looking for.

You can power/charge it from a usb connection. I was using an old iPhone charger.

It can be plugged in via USB as a webcam, for file transfer, or printing, but there's no way to use it in "normal" camera mode without the battery. USB is the only external power source - and works without the battery - but only as an external webcam connected to a computer.

You do not have to connect this to a computer. It powers up by means of the vehicle battery. Now, it does come with instructional DVD's that you need a computer or a DVD player for but the tool itself does not.
