When you’re having those long days away from the office. a backup battery for your phone is only useful if you’re willing to carry it with you. Native Union is looking to change that with JUMP, their take on a smartphone’s charging cable with a bit of internal battery. This small, compact device brings a trio of technologies together to make your lifestyle simple: Cable + Battery + Intelligent Circuitry.

No longer a need to carry a charging cable & that bulky battery pack, when you’ve got both in compact device that fits in your dress shirt pocket. The device pack a 800mAh battery into a compact form factor that weighs less than two AA batteries, giving you 3 hours and 50 minutes of additional talk-time for those situation where you’re nowhere near a power supply. AutoCharge, the intelligent circuitry technology built into device detects when the battery inside your smartphone is full, and automatically redirects the power to charge the batteries inside JUMP.

The project is ending it’s Kickstarter in few days and  its funding goal of $40,000 has already been surpassed sevenfold. You can pre-order a JUMP for yourself—available in both microUSB and Lightning versions—  until February 13th for $40.
