Q: On the side of the PowerPack 10K, there's a button and small light. What are these things used for?
A: The side button has several functions.
1. To check the battery level (how many of the four lights are flashing).
2. To manually wake the PowerPack up from sleep (after 30 seconds of no use).
3. To switch between Qualcomm Quick Charge and normal charge.
4. Double-press to turn on low power charging mode for Bluetooth devices, smartwatches, and other low-powered devices.
Toggling between fast charging (Qualcomm Quick Charge) and normal charging is one purpose. The fast charging facility of this battery pack is for Android phones such as the Samsung Galaxy series. The battery pack does not support the fast charging technology used in the Apple iPhone or Google Pixel. If you have one of these devices and would like to use fast charging, please check out the ZMI PowerPack 10K USB-C PD portable charger.
