How to use

Connect a device to the built‑in USB‑C cable, USB‑A port, or Lightning cable to begin charging. Use the USB‑C input to recharge the power bank itself following the specified input ratings. The LCD display indicates the remaining battery level so you can monitor when to recharge the unit. When charging several devices simultaneously, output power may be shared between ports and the total per‑port power can be reduced.

Usage recommendations

To prolong battery life, avoid exposing the power bank to extreme temperatures and recharge it before long storage. If charging multiple devices at once, expect reduced per‑port output (the shared power may be limited to 15 W total under some conditions).
