The small energy giant Terratec P50 Pocket accommodates a capacity of 5,000 mAh in a compact housing measuring 93.5 x 64 mm. Thanks to high-density technology, the Powerbank is hardly larger than a credit card and is only 13 mm deep. It is therefore hardly noticeable in a handbag or shirt pocket. Via USB or USB type C output, it supplies Smartphones and Co. with power while on the move and protects them from excessive charging and discharging.
