4. Operating Instructions
4.1 Charging Your Devices
The Philips DLP2557CB offers multiple ways to charge your devices:

- Using the Built-in Type-C Cable: Extend the built-in Type-C cable and connect it to your device's Type-C port.
- Using an External USB-C Cable: Connect your device to the power bank's USB-C output port using a separate USB-C cable.
4.2 Apple Watch Charging
The power bank supports cordless 2.5W magnetic charging for your Apple Watch.
- Press the power button on the side of the power bank to activate it.
- Place your Apple Watch onto the magnetic charging area on the power bank. Ensure it is properly aligned for charging to begin.
Note:
- For single device charging, activate the mobile battery by pressing the power button.
- When charging multiple devices simultaneously, the power bank automatically switches to a low current mode.
4.3 Pass-through Charging
The power bank supports pass-through charging, enabling simultaneous charging of your Apple Watch, smartphone, and the power bank itself. Connect the power bank to a power source, then connect your devices to the power bank.
Note:
When multiple devices are connected, the fast charging mode is automatically disabled, and the total maximum output power is 15W.
4.4 LED Display
The integrated LED display clearly shows the remaining battery percentage of the power bank and indicates the fast charging status. A green indicator light signifies active fast charging or discharging.
Note:
If your smartphone's optimized battery charging function is enabled, the green fast charging mark may turn off once the device reaches 80% charge. This is normal behavior and does not indicate a malfunction.
5. Maintenance
To ensure the longevity and optimal performance of your Philips DLP2557CB Mobile Power Bank, please follow these maintenance guidelines:
