Superslim (9.9mm) 5000 mAh powerbank from chinese manufacturer Xiaomi (original documentation and seal included).
It was selected due to its superior performance with 2.1 A output (Charges your phone fast) and build quality with battery cells from reputable suppliers and good battery safety.
You may need a powerbank if you have a phone that doesn’t let you use voice control when the screen is locked. It will also be useful for those long rides with navigation if your scooter or bike doesn’t have a built in USB port.
