They require batteries, I gave them as a gift to my son in law, but I believe they run on 3V batteries.

The one I have uses the 123 batteries. They do make rechargeable ones but you will have to remove the battery to recharge them.

It takes AAA batteries. Just about any type of rechargeable AAA should work. You would need to buy a batter charger to charge them. Most electronics stores carry charges with batteries included. Get something like that.

There is no battery to be charged. You need a long, heavy duty extension cord to plug it in while using it. There are instructions about the best way to do this while avoiding running over the cord.

You just need a USB charger to power the unit. The power supply voltage is immaterial.

Electric. Plug it in. I don't think batteries would ever give enough power.

it must be plugged into a wall socket. Or if you have a power inverter you could use a 12vt outlet. It does not have a battery in it.

It does not ship with a rechargeable power source. You can use rechargeable "AA" batteries in the radio and they will recharge if given an external charger (not provided) like a USB-based cell phone charger. You will need a standard mini-USB (not micro) cable.

Micro USB to USB cord is included to charge, any micro usb cord should work as well.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.
