Should you ever run out of power on the road: This power bank works like an additional battery for your smartphone or tablet and is suitable for mobile devices from various manufacturers thanks to the included adapters. The small energy bundle is not much bigger than a credit card and can temporarily store up to 2600 mAh (milliampere hours) with a charging time of 3 hours. A practical little helper for situations where there is no power socket nearby. In addition, it can be charged wonderfully with sunlight. Perfect for longer trips or even for open-air festivals.
