To get the result, we calculate the energy of each battery, divide it by the efficient energy of Brick's power bank, and multiply it by the efficiency coefficient. Brick’s power bank energy: 5000mAh *3.7V = 18.5 Watt-hours; iPhone battery cell energy: 2815mAh * 3.7V = 10.4 Watt-hours; Efficient coefficient: input * output => 0.85*0.85 = 0.7225
How to Choose Power Banks. 1. Choose 10,000 mAh Above so You Can Charge Your Devices Multiple Times. 2. Check Its Ports to Ensure Compatibility With Your Device. 3.

The powerbank is 30000mAh at 3.6V, which equates to about 100Wh. So the total capacity of the steam deck is 40% of the Powerbank. Taking conversion losses into account, 30000mAh powerbanks should barely charge the steam deck twice.
Wh = (mAh / 1000) * Voltage. Using the above example, the calculation would be: Wh = (10,000mAh / 1000) * 3.7V = 37Wh. It’s important to note that Wh represents the total capacity of the power bank, regardless of the number of devices it can charge or the number of times it can fully charge a specific device.Best portable high-capacity power banks, including 50,000mAh+ chargers 2024 | Android Central.
