Another great product from our friends at Poldera. The X4000 is their newest release and combines some great features with a cool-looking, black rhombus stealth design. It has a 4000mAh rechargeable internal battery that for your phone translates into 16 hours of talk time, 650 hours of standby time, 22 hours of internet time, 90 hours of music time or 22 hours of video time. We like that it has 2 ports to charge your devices simultaneously and at the push of a button, you can check the power level. Before your next camping trip or extended hike, charge up the X4000 with its foldable wall plug, and you’ll have back up power at your fingertips!
