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

Can use the A/C adapter instead of batteries. Have not tried to power it with just the USB, but it might work.

I haven't tried the USB option, Carlos. I use batteries because I like to take it with me to places I can't plug it in. But it does come with a power cord, & that may be an option at air ports. Happy playing!! Jim C. ;o)

I don't recommend using a USB flash drive. Use a powered external hard drive.

You can use it with batteries or an adaptor! You can buy it together in amazon

No. The usb is for using the batteries to charge small devices like a phone.

unless you have one of those USB Back up battery for when you don't have electricity. You'd still need to plug it into a power source. Doesn't have a stand alone battery.

It can be powered used via usb. But I wouldn't recommend it because it's possible you could burn out the internal battery

I believe just uses the regular batteries or perhaps could use rechargeable batteries but does not charge the batteries, nor a usb. a simple lamp that works for our purposes very well. great for camping too.

Thank you so much for the explanation! I was worried that the USB is only for file transfer but not for charging battery, but this answered my questions!

You can buy a power supply to eliminate the need for batteries. Check the instructions or go to google for more information.

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.

It is better as a USB power but it can work also as a battery. but i suggest use it as a USB power

Already answered, also keep in mind this is a desk lamp, the USB port is for charging there are no batteries in unit.

No Usb needed However this is not too reliable maybe a different brand may work.

Yes, works with AC adaptor only. I don't even put batteries in unless I'm going to be using it where AC isn't available.

It is rechargeable by USB. Not sure about battery because I don't use it much so haven't looked for a battery to change.

Of course! But don't connect it to the USB cable with a standard battery-- when it's used in wired mode it automatically recharges the battery. That would be bad.
