A method of activating a mobile device power and

The present invention relates to the field of power supplies, a method and apparatus is activated mobile power. When the circuit is broken between the mobile power supply DC / DC module with the battery protection circuit, the main controller automatically activates the detection circuit switch is depressed; if, in the automatic activation current generating circuit, the on DC / DC and the circuit between the battery protection module; when the circuit is turned between the DC / DC module with the battery protection, the main controller detects the load recognition circuit to control the load level low DC / DC module starts output load current detection AD acquisition circuit voltage side of the load resistance changes according to the output of DC / DC modules, the main controller receives the voltage according to the current computational load signal AD, and sent to the display screen. The present invention can be activated only mobile power reset switch, the load cell continuously adjusting the output according to the load current, and displays the current value of the load.
