Just Mobile Gum++™

The high-style, high-capacity backup battery is reborn

Just Mobile Gum++™ is the redesigned backup battery for smartphones, tablets and USB-powered devices.

Available in a range of striking colours, the Gum++™ is clad in a glossy, hard-wearing shell. Inside, an improved 6000mAh battery has enough capacity to recharge a smartphone up to three times, or add precious extra hours to a tablet. And its high-power USB output keeps charge times to a minimum

You can refill the Gum++™ from USB using the supplied cable, and its five LED indicators help you keep track of remaining charge - so you’ll never be caught without power again. 

Also compatible with iPhone 5*, iPad 4*, iPad mini* and iPod touch (5. Gen.)*.
(*Lightning to USB cable not included)
