To charge devices, connect them to the USB‑A or USB‑C outputs using the appropriate cables. The LED display indicates remaining battery level; monitor it to plan recharging. When charging multiple devices, be aware that available power may be shared across outputs and per‑port maximums will apply.

Usage recommendations

For safe and optimal performance, use chargers and cables that meet the specified voltage and current ratings. Avoid exposing the power bank to extreme temperatures or moisture. When charging several devices, note that output power is distributed between ports and maximum per‑port power may be reduced. Comply with transport regulations for high‑capacity batteries when flying—this unit contains a 111 Wh battery.
