A power bank is a great power backup for all your electronic devices, such as mobile phones, navigation devices, camera or tablet. This one can charge two devices simultaneously as it has a dual power output of DC 5 Volt with 1 or 2.1 Amps. It features 10,000 mAH Lithium Ion batteries, as well as a digital backlit display showing battery status and a bright shining LED flashlight. The Carrera Powerbank charges from a normal USB port or any standard DC 5 Volt 1A USB power adapter with the supplied cable (power adapter not included). Fits easily in your pocket when you are on the road, as it measures just 71x106x22mm (2.8"x4.17"x0.866") and weighs only 250 gram. Comes complete with a USB cable with adapters for most devices. (Does not come with Apple Lightning adapter, but does work with USB to Lightning cable that comes with Apple devices).
