Microsoft will soon release a new portable charger that has the energy to provide enough power to charge most smartphones twice. Hidden inside the Microsoft Portable Power sits a 6000mAh rechargeable battery, which charges to 80 percent capacity in about three hours, and 100 percent in about four hours.

To charge your smartphone, plug in any USB-A charging cable. Thanks to the universally compatible USB interface, it’ll more than likely charge your other devices, too.

Because of the device’s low standby battery consumption, it keeps a full charge for months. Even after six months, the Microsoft Portable Power will have 80 percent of power.

But if you do want to top up the stored power, you can do so via USB. Alternatively, you can daisy-chain the Microsoft Portable Power and your Lumia together and charge both at the same time.

Priced at $49 USD, the Microsoft Portable Power will be available in white, bright green and bright orange, and will be hitting the stores in October.
