Yes. It says so in the description. Not in the description: It comes with a transformer to plug into a 110V outlet. On the other end is a cord and mini-USB connector. On the light, the top rubber plug pulls out to reveal the mating female connector. The center light turns white/blue when it is fully-charged.

Yes it is. I bought an AC adapter, by itself, that has a USB port on it. I charge mine overnight while I'm sleeping.

It is rechargeable and it comes with its own usb chord. However the chord is short so playing while it's charging isn't much of an option. Sorry I was really late with you answer.

Hello. Yes they are rechargeable. However please note that they use mini USB connector rather then micro USB. It's not a big deal but somthing to be aware to.

Yes, it's rechargeable, but it also has an DC 5v adapter that you can plug into a USB port. You can run off the DC power if you connect the speaker to your device with the auxiliary cord (plugs into the headphone jack of your device).

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