A 20-hour rechargeable battery and dual-device Bluetooth 4.2 connectivity make the Charge 4 the ultimate party speaker. Meanwhile, a 30-watt RMS power amp, full-range 3.5" driver, and two side bass radiators crank out bass you can feel and an extended 60Hz–20kHz frequency response. IPX7 water resistance protects the Charge 4 from the occasional spill or dip in the pool. The Charge 4 also features a USB port to charge your device while you indulge.
