The universal external battery "Reserve Pro" features a reliable class "A" lithium-polymer battery with a capacity of 10000 mAh and dimensions smaller than a modern smartphone. The body is made of high-quality ABS plastic with an anti-slip soft-touch coating. The body includes three of the most popular input connectors (USB Type C, micro USB, Lightning), which means you can use one cable for charging the power bank and your smartphone. The USB-C connector also works as an output, so the power bank can charge up to 2 devices simultaneously. The package includes micro USB, Lightning, and symmetrical USB-C - USB-C cables. The multi-level protection system protects against voltage surges, short circuits, overheating, and overcharging.
