Basic knowledge about power adapters

What are the basics of popularizing power adapters?

1, the main performance indicators of the power adapter:

(1): rated output current;

(2): rated output voltage;

(3): marking and instructions for use;

(4): power plug size;

(5): Risk of electric shock under normal working conditions;

(6): normal work fever;

(7): fault condition;

(8): Mechanical strength.

2. Need to pay attention to the problem when purchasing the power adapter:

(1): Purchase goods produced by regular manufacturers;

(2): Purchase products with “3C” “UL” or other certification mark;

(3): Purchase the original mobile phone charger for your mobile phone;

(4): Look at the appearance of the charger. For example, the seams of the casing are fine and neat.

3, the charger suitable working environment:

(1): Waterproof and moisture proof: (Do not use the charger near the bathtub, washbasin, etc., or in the wet basement);

(2): Anti-cold and heat-proof: (High temperature will shorten the life of the electronic device, deform or melt the plastic parts. If it is too cold, moisture will form inside the charger and destroy the circuit board.);

(3): Anti-drop and shockproof: (Electronic components damage will burn the circuit board, and the casing is damaged and there is danger of electric shock.) Do not plug or unplug the charger with wet hands, otherwise it may cause electric shock.
