1000 milliamps (mA) or 1000 milliamps (mAh)? The capacity marked on the battery is either milliampere-hour (mAh) or watt-hour (wh).
It can be calculated according to the following formula
Suppose the discharge voltage is 5V
W=Pt=UIt=QU=1Ah*5V=5wh=0.005Kwh (degree)
Therefore, a battery with a capacity of 1000 mah, without considering the loss, requires 0.005 KWH of electricity, that is, 1 KWH of electricity can be filled with 200 batteries

What is the voltage of the battery? If it is 5V, it is 0.005 KWH, if it is 10V, it is 0.01 KWH
If it refers to mobile phone charging, one degree of electricity should be the energy unit of one degree of electricity = one kilowatt-hour 1000 mah rechargeable battery energy =3.7V x 1000 mah x 1 hour = 3.7W one hour. The normal voltage of the mobile phone battery is 3.7V once charge times =1 KWH ÷3.7 W 1 hour =1000÷3.7=270.3 times, so the 1000 mah battery can be charged 270.3 times with 1 electricity (must be fully discharged and fully charged each time).
Wrong answer on the first floor. Second floor correct, 1 KWH, is 1000 watts *1 hour. w=uit, where u is the voltage, i is the current and t is the time.
If u and t are both 1, 1 KWH =1v*1000a*1t. So one degree of electricity is 1,000 amps, which is 1,000,000 milliamps.
