• Via USB-C Port: Connect a USB-C to USB-C cable (not included, unless using the built-in one for pass-through charging) from a power source to the IN/OUT USB-C port on the charger. The digital display will indicate charging status.

A full recharge from 0% takes approximately 2 hours.

Operating Instructions

Charging External Devices

The INIU P21 offers multiple options for charging your devices:

• Using the Built-in USB-C Cable: Unclip the integrated USB-C cable and connect it directly to your USB-C compatible device (e.g., iPhone 15/16, Samsung S24, MacBook Air). This cable supports 30W fast charging.

• Using the USB-C Port: Connect your device using your own USB-C to USB-C cable to the IN/OUT USB-C port. This port also supports 30W fast charging.

• Using the USB-A Port: Connect your device using a standard USB-A cable to the OUT USB-A port.

Simultaneous Charging (Pass-Through Charging)

When the INIU P21 is plugged into a wall outlet, it can charge itself and up to three external devices simultaneously. Devices connected to the charger will be prioritized for charging. Once external devices are fully charged, the power bank will continue to recharge itself.
