In addition to the various fast charge technologies of various manufacturers on the market, the power of ordinary mobile phone chargers is generally: 1, input: 100-240v~50\/60Hz, that is, the voltage is 100V-240V(and 5
< br >
Within 0-60HZ), the current should reach 65mA. If the voltage is too high, the charger is easy to damage, too low to meet the output requirements. 2, output: 5V~1000mA, the output value of 5V and 1000mA is the electrical appliance must be 5V, and the current does not exceed 1000mA. 3. After the battery is full, the standby (non-charging) power of the charger is within 0.3W.

4, many mobile phone chargers now power 10W or 18W.
General smartphone charger output voltage is 5V, output current 1 ~ 2A. Therefore, the output power is 5 ~ 10W.

The general feature phone, due to the small battery, the output current is generally 0.5A, and the output power is about 2.5W.
The charger is divided into the input end and the output end, the input voltage in the country is 220W, that is, the voltage at home. The output usually starts from 5V, 800mA (0.8A) or 5V, 1A, which is the standard USB2.0 voltage and current output.
The power number is how many watts you say, according to the formula P=U·I, you can calculate the power is 5Vx1A= 5W.
The wattage of the mobile phone charger generally refers to the output part, the output wattage = output voltage x output current. The traditional 5V1A charger is 5 watts output; The 5V2A has a 10 watt output.
Now there are many fast charging mobile phones, some chargers can reach 24 watts output, the output voltage and current can be automatically adjusted to match the actual working state of the mobile phone and data line, and get the best output conversion efficiency.
