Harman has joined several other companies in jumping the CES gun, announcing five new products it's bringing to the show. First up is the JBL Charge, a hardy Bluetooth speaker which promises an impressive 12 hours of tunes on a single charge. If you are willing to sacrifice some of that play time, you can siphon power from the internal battery to other kit via the speaker's USB port. Expected to start shipping in Q1 2013, you should be able to pick one up for around $149. Joining JBL's OnBeat
