Who doesn't know it: You're on a bike tour, hiking, traveling, on a long flight, or at a friend's place, and suddenly the battery indicator of your smartphone or laptop is nearing empty - and there's no charging option in sight. This problem is now a thing of the past, as the practical power bank with an elegant design is lightweight, powerful, and always at hand. Due to its compact design, this lightweight power storage fits in any jacket, pants, or handbag. Equipped with a USB to Micro-USB charging cable, this product is the ideal companion for on-the-go. The built-in overcharge protection ensures that the power bank automatically stops charging once the device is fully charged. The deep discharge protection turns off the power bank as soon as the voltage drops below a certain level while charging a connected device, preventing damage to the battery and the product. The short circuit protection completes the safety features and, along with the automatic shut-off, ensures maximum safety.
