Operating Instructions

Charging Devices

The power bank offers multiple ways to charge your devices:

• Using Built-in Cables: Pull out the integrated Lightning or USB-C cable and connect it directly to your device.
• Using USB-A/USB-C Ports: Connect your device's charging cable to the appropriate USB-A or USB-C output port on the power bank.
• Wireless Charging for Apple Watch: Place your Apple Watch onto the magnetic wireless charging module. Press the power button once and wait 3-10 seconds for wireless charging to activate. The LED display may show a charging indicator.

The power bank supports 20W Power Delivery (PD) fast charging via its USB-C port, allowing for quick recharges of compatible smartphones.

Pass-Through Charging

The power bank supports pass-through charging, allowing you to charge your devices while the power bank itself is being recharged. When the power bank is connected to a power source and devices are attached, the devices will charge first to 100%, and then the power bank will begin to recharge.
