It has a 14V wall charger that will take it from 1/2 to full in an hour. It can also charge through the USB port, but that is slow, and music can't be played while connected that way.
I don't know how much it weighs.
So far its been great. I can't believe how long the battery lasts. I had it going for 8+ hours at full volume, and it still reported half full.

I still love the little Android guy bluetooth soundbox I won from this forum, sound on that thing is amazing. Poor little guy fell over though and broke one of his antenna off, that made me sad
