Think the load of Bluetooth speakers announced at CES is rather ho-hum? Well, Braven has something to say about that. The company's new BRV-PRO Bluetooth speaker sports the rugged look we've come to expect from them, and claims 20 hours of battery life on a charge. Those are easily the two least interesting things on the spec sheet for the outdoor audio device. Up top, the BRV-PRO swaps out accessories as needed, including an extra 2,800mAh battery pack, LED glow deck (think of it as a lantern of sorts), stacking plate and a folding solar panel (pictured above) for all-natural recharging. Touting an IPX7 waterproof rating, the aircraft-aluminum-clad gadget will also juice up your phone or tablet when you're out on the trail. Looking to pack one for that next outdoor trek? The BRV-PRO is scheduled to arrive in Q2 for $150; the accessories cost extra, ranging from $30 to $50 each.
