JBL Portable Bluetooth SpeakersThe Charge 3 and Pulse 3 are both high-powered portable Bluetooth speakers which are built to pump your tunes for hours on end. Both speakers have 3.7V lithium-ion batteries providing 22.2-watt-hours of power. The Charge will play music for about 20 hours and is able to charge other devices like a smartphone or tablet via a USB cable, though this reduces music play time. While the Pulse lacks device charging capabilities, it makes up for it with a colourful display. With both the lights and music going, the Pulse will last about 12 hours.
