Abstract

The invention provides an APO (Automatic Power Off) phone charger. The APO phone charger comprises a shell, a timing button, a power-off protection unit, a display screen, a charging circuit and a USB connecting wire, wherein the power-off protection unit and the charging circuit are both arranged in the shell; a controller is respectively connected with a timer and the display screen; the timing button is arranged on the shell and is connected with the timer; the shell is provided with a USB interface; the charging circuit is connected with the USB connecting wire through the USB interface; the power-off protection unit comprises the controller, a relay and the timer; the charging circuit is connected with a mains supply through the relay; the relay is further connected with the controller. The APO phone charger has the function of automatically disconnecting the charging circuit from the mains supply. The APO phone charger has the advantages of realizing power-off protection of the charger, enhancing the use safety of the charger and avoiding such potential safety hazards of the charger as earlier damage or spontaneous combustion due to long-term working; after powering off, since the charger does not work continuously, energy can be saved to some degree.

Description

technical field [0001] The invention relates to an automatic power-off mobile phone charger. Background technique [0002] The mobile phone charger converts high voltage into low voltage through a transformer. If it is not unplugged for a long time, it will always work. The charger still consumes power if it is not unplugged, and the largest power consumption of the mobile phone charger is 308 milliwatts. The charger is not unplugged from the power socket. Although the charger is not connected to the mobile phone, the circuit board inside the charger is powered on and still working, which will still consume power. [0003] After the charger works for a long time, the charger will heat up, and the insulation layer of the coil may be melted, causing a short circuit. The charger is very small, there is no space and no heat dissipation, whether it is overheated or short-circuited, it is easy to cause combustion. Generally, a mobile phone can be fully charged within 4 hours at...
