Abstract

When traveling outdoors or on the way trip, sometimes we encounter the situation: the mobile phone run out of power, but there is no charging equipment. In this situation, the disclosure can provide an extra hardware or software switch which can be added into mobile device and enable/disable auxiliary power supply (APU model). When APU model is enabled in mobile device which means it is ready for supplying/receiving power, the power will be transferred between the USB interfaces. The power doesn't charge the battery but can supply power directly to the receiver.

This situation will be more outstanding when several mobiles all lost power but all they need to power on for several minutes to do important operations. If we know we can not get normally charged in a long time, we need try our best to save the power and use them in the key places.

The present disclosure provides an extra hardware or software switch which can be added into mobile device and enable /disable auxiliary power supply (APU model).
