Are there cameras that run on batteries?

Question

Video

Good afternoon.
Tell me if there are camcorders (small in size) that can be powered by AAA (LR6) batteries and / or charged via a usb connector. I look at Yamarket, but I can’t find anything suitable.

Answer 1

So you need an action camera. What's not to like about GoPro4 ? Yes, she does not have finger batteries, but she is charged from usb and you can buy 1-2 batteries for everyone.
Micro USB
Rechargeable lithium-ion battery
Rated at 1000mAh, 3.8V, 3.23Wh
Using external power during recording
Connecting to a computer for playback/file transfer/charging

Answer 2

Because in our time, video powered by AA batteries is nonsense.
Camcorders consume too much electricity. And lithium batteries are available.
On batteries, they will work for 20 minutes.
Who needs it?
