How to use

Connect the power bank to your device using one of the integrated cables or an external USB cable plugged into the USB-A or USB-C port. Ensure the device is compatible with the output type and power. To recharge the power bank itself, connect it to a suitable USB power source using a supported cable and charger; charging time depends on the input current and charger capabilities. Monitor any indicator LEDs on the unit to check remaining charge and charging status.

Recommendations

Use a charger with appropriate output ratings to recharge the power bank safely, avoid exposing the unit to extreme temperatures, and store it partially charged for long-term storage. When charging high-power devices, connect one device at a time to maximize charging speed if simultaneous charging reduces output per port.
