The utility model is achieved through the following technical solutions:

A charger box, including a box body, a power cord and a power plug. The rear end is a plug room, the transformer chamber has a built-in transformer, the transformer is connected to an external power supply, and the voltage adjustment knob of the transformer is located on the outside side of the transformer chamber.

A display screen is installed on the top of the transformer chamber, which can display the voltage adjusted by the voltage adjustment knob to meet the electricity demand of various household appliances.

The other side of the transformer chamber is equipped with a loudspeaker, which can remind the user that the electric appliance is fully charged and reduce damage to the electric appliance battery.

The plugs in the plug chamber have flat head, cylindrical, square head, double-blade plugs, etc., which can meet the charging needs of different household appliances such as smart phones, ordinary mobile phones, shavers, flashlights, and computers.

A heat dissipation fan is installed in the cooling chamber, and a vent is provided on one side of the cooling chamber to dissipate the heat in the charger box in time to prevent damage to the charger box due to excessive temperature.

A box cover is installed on one side of the plug room, and the box cover and the plug room are connected by a hinge. The box cover can be closed when not in use. When the electrical appliance needs to be charged, the box cover can be lifted to one side of the plug room. Does not affect the use of the plug.

The beneficial effects of the utility model are: the utility model is a charger box, which is simple in structure, convenient and practical, can meet the different needs of various household appliances for voltage and plugs, is convenient to find and carry, and solves many unnecessary problems for people. trouble.
