How to convert from electric charge of ampere-hour (Ah) to milliampere-hour (mAh).
The electric charge Q(mAh) in milliampere-hours (mAh) is equal to the electric charge Q(Ah) in ampere-hours (Ah) times 1000:
Q(mAh) = Q(Ah) × 1000
So milliamp-hour is equal to amp-hour times 1000mAh/Ah:
milliamp-hour = amp-hour × 1000
or
mAh = Ah × 1000
Convert electric charge of 2 amp-hour to milliamp-hour:
The electric charge Q is equal to 2 amp-hour times 1000:
Q = 2Ah × 1000 = 2000mAh
Convert electric charge of 4 amp-hour to milliamp-hour:
The electric charge Q is equal to 4 amp-hour times 1000:
Q = 4Ah × 1000 = 4000mAh
Convert electric charge of 6 amp-hour to milliamp-hour:
The electric charge Q is equal to 6 amp-hour times 1000:
Q = 6Ah × 1000 = 6000mAh
Convert electric charge of 20 amp-hour to milliamp-hour:
The electric charge Q is equal to 20 amp-hour times 1000:
Q = 20Ah × 1000 = 20000mAh
Convert electric charge of 50 amp-hour to milliamp-hour:
The electric charge Q is equal to 50 amp-hour times 1000:
Q = 50Ah × 1000 = 50000mAh
10,000mAh /1,000mAh=10 hours. If you use a 5V/2A power adapter, it takes 5 hours to fully charge the power bank: 10,000mAh/2A (2,000mAh) = 5 hours.
A 4000 mAh battery life can last up to 4,000 hours, depending on the current required by the object being operated (measured in mA). You can calculate battery life by dividing the battery capacity by the current required for the object.
Its 5000mAh battery allows your phone to last long without recharging, 13 hours of video watching, 27 hours of call time and 40 hours of standby.
3-4 hours
Built-in 1200mAh rechargeable lithium battery, provides 3-4 hours of play time, and is fully charged in 2 hours via the supplied micro-USB cable. You can enjoy music all day or all night, alone or at a party.
1000 mAh is equal to 1 ampere hour (Ah) rating.
100 amperes A 100Ah battery has a capacity of 100 amps at its disposal. How long this can last depends on the electrical requirements of the applications you are operating and how many of them there are. A 100Ah hour battery will supply 100 amps of current for 1 hour, 50 amps for 2 hours, or 100 amps for one hour.
240 W = minimum 20 amp load at 12 volts, a 7 Ah battery is designed to supply a 350 milliamp load for 20 hours and is designed to gun out at 10 volts.
How to Convert Amps to Milliamps (A to mA) There are 1000 milliamps in 1 amp, just like there are 1000 milliamps in 1 meter. So, to convert amps to milliamps, simply multiply amps by 1000.
The formula to calculate the mAh of a battery is as follows: Mh = Ah * 1000/temp Mh is the mAh of the battery. Ah is the capacity of the battery expressed in milliamps. Temperature is the temperature of the battery expressed in Celsius.
A milliampere hour (mAh) is one 1000th of an ampere hour (Ah). Both measures are commonly used to describe the energy charge that a battery will hold and how long the device will last before the battery needs to be recharged.
