How to use

Connect the power bank to a power source using the supplied USB‑C to USB‑C cable to charge the internal battery; observe the LED display to monitor charge level. To charge external devices, connect them to one of the USB‑A or USB‑C output ports using appropriate cables. When charging multiple devices simultaneously, output power is shared between ports; expect reduced maximum power per port in multi‑device scenarios. Follow device manufacturer recommendations for cable and adapter selection to ensure optimal charging.

Usage recommendations

For best performance, charge the power bank before long trips and avoid exposing it to extreme temperatures. Use certified cables and compatible chargers to maintain the specified input and output currents. If charging several devices at once, be aware that available power will be distributed among connected devices, which can lengthen overall charging time.
