Wh means Watt-hour. 100 Watt-hour battery can deliver 100 watt power for 1 hour, 20 watt power for 5 hours. This is a unit BiXPower likes to use since it is much more accurate and can compare between different batteries. A 200 Wh battery has more capacity than 100Wh battery for sure. 2. mAh or Ah, means Milliamps Hour (mAh) or Amps Hour (Ah). EVM Laptop Power Bank LAPPOWER- World's only power bank with 3 years of warranty, Air Allowable, Ultra Black Premium Metal Body.

One amp (1,000 mA) represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. Convert Watt hour to Amp hour (Wh to Ah) Insert Watts-hour (Wh) and voltage (V) below and click on Calculate to obtain Amp-hours (Ah). Wh. V. Ah. Formula is (Wh)/(V) =(Ah).

So watt-hours is equal to milliamp-hours times volts divided by 1000: watt-hours = milliamp-hours × volts / 1000. or Convert mAh to Watt hours Insert milliamp hour (mAh) and voltage (V) and click on Calculate to obtain Watt hours (Wh). Formula is (mAh)* (V)/1000 = (Wh). For example, if you have a 300mAh battery rated at 5V, the power is 300mAh * 5V / 1000 = 1.5Wh. mAh to Wh Conversion Formula Wh = (mAh × V) ÷ 1,000 Thus, the energy in watt-hours is equal to the charge in milliamp-hours times the voltage, then divided by 1,000. For example, convert the charge used by the average C battery, which is 8,000 mAh at 1.5 V, to Wh. 1 ampere is equal to 1000 milliamps, or 1 watt/volt. Note that rounding errors may occur, so always check the results.
1000 mAh: 1 Ah: 10000 mAh: 10 Ah: 100000 mAh: 100 Ah: 1000000 mAh: 1000 Ah . Ah to mAh conversion
Thus, a battery if a mAH specification of 1900mAH can provide 1900mA (milliamperes) for 1 hour of time.

For example, if you have a 2 Ah battery rated at 5 V, the power is 2Ah * 5V = 10Wh. Convert 1.5 Ampere to Watt/Volt with our online conversion. 1 when you convert the battery with the same volt and same Ah or mAh, you can use the fomula and just ingore the volt 2 To check how to calculate how long a battery will last, the difficult part would to define the consumption of the device, as it’s changing all the time You are currently converting energy units from joule to watt hour 1 J = 0.00027777777777778 Wh Our online tools will provide quick answers to your calculation and conversion needs.

Being that batteries are sources of power and give out current when connected to a closed circuit, all batteries, whether standard or rechargeable, provide The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts (V = W/I) Example: 1.5A * 12V = 18W Converting Volts to Amps - If you know Volts and Wattage is fixed DC amps to watts calculation. The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V): P (W) = I (A) × V (V) AC single phase amps to watts calculation. The power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V): P (W) = PF × I (A Incompatible units. mAh is an approximate measure of the energy available from the battery if you know the voltage. If it was a 3V battery, for example, it would have 9,000 mW hours, or 9 W hours, of energy available. In simple words 1KW used for one hour is one unit.
