How to use

Connect your device to the appropriate output port using the compatible charging cable. For fastest charging on supported devices, use the USB‑C port with a PD‑capable cable and ensure the device accepts PD or QC3.0 input. To recharge the power bank, connect a USB‑C cable to the input port and a suitable power adapter; charging times depend on the adapter output. Observe the LED indicators to monitor remaining battery level and charging status. Disconnect devices once fully charged to preserve battery cycles.

Usage recommendations

Use a certified USB‑C to USB‑C or USB‑A to USB‑C cable rated for fast charging to achieve PD 20W or QC3.0 performance. Store the power bank in a cool, dry place and avoid exposure to extreme temperatures. For long‑term storage, recharge to around 40–60% every few months to maintain battery health. If the power bank becomes warm during charging, allow it to cool before further use.
