The power bank includes one USB-C and one USB-A port, allowing for charging multiple devices simultaneously.

Enhanced safety is ensured with ActiveShield 2.0 technology, which monitors temperatures and adjusts power output to prevent overheating and ensure safe charging. The compact size (4.72 x 2.9 x 1.24 inches) and relatively light weight (11.2 ounces) make it portable and easy to carry.
