How to understand the data on the charger nameplate

:input: AC 100-240V (input voltage), 50-80Hz (input frequency), 180mA (input current)

output: DC 5.0V (output voltage),800mA (output current)

seat charger (free when you buy a cell phone): input: DC 5.5V=1A

output (output): DC 5V = 500mA

Newly bought direct charger: input (input): 220 ~ 50Hz ≤ 60mA

output (output): ≤ 10.5V = ≤ 700mA

Input voltage refers to the voltage of your power supply is generally 220 volts,

The more the rechargeable battery is charged, the more it is charged. rechargeable batteries, the slower the charge, the better, charging current is 1/20 of the battery capacity is best.
