Let’s do a simple mah to watt calculation using two examples: Example 1: A 10000 mAh Smartphone battery with 3.7V. (10000 × 3.7) / 1000 = 37 Wh. If used over 1 hour, it gives you 37 Watts.
Over 2 hours of use, the actual output will be 50 Watts per hour. The output is necessary while comparing the advertised capacity with actual power output when charging multiple devices simultaneously. The use of mAh to watt formulae and the mAh to Wh calculator is essential while evaluating the efficiency of the device.
For example, a 20,000 mAh battery at 3.7V will have approximately 74 Wh (20,000 x 3.7 /1000). However, while charging devices with varied power requirements, efficiency losses like heat and light or sound dissipated must be taken into account.
The measure of total battery capacity converted into watts, the mAh to watts calculator is used to convert the mAh into real power output. The Watts can be manually calculated also if you don’t wish to use any online tools when converting mAH to WH. Watts = (mAh × Volts) × Time (hours) ÷ 1000. Runtime is approximately 15.7Wh divided 5W = 3.14
