If you prefer to have an extra portion of power with you when you're on the go, the Charge 20 power bank from BioLite is the right choice. With IPX6 certification, the battery in the stainless steel housing with a silicone cap is protected against splashing water. The battery can even withstand brief flooding. How much power is still in the battery, is shown by the charge level indicator with 4 LEDs. When no LED is lit anymore, it is time to recharge the power bank. TO charge the power bank, simply plug the included micro-USB cable into the micro-USB input and plug the normal USB end into a standard USB charging plug or BioLite power source.
The lithium-ion battery provides 20 Wh at 5200 mAh and 3.6 V. The charging output is 2.1 A. The compact size takes up only 98 x 38 x 21 mm of space while weighing a little more than a chocolate bar, 165 g.
