While both measure energy storage, Wh is often a more accurate way to compare power banks for laptops, as it accounts for voltage. A 65W laptop power bank’s capacity is usually listed in mAh, but it’s helpful to understand the Wh equivalent for true comparison.
To convert mAh to Wh, you multiply the mAh by the voltage and then divide by 1000. For example, a 20,000mAh power bank with a typical internal voltage of 3.7V has a capacity of approximately:
(20,000 mAh 3.7V) / 1000 = 74Wh
A laptop might consume anywhere from 15W to 65W or more depending on its model and what it’s doing. A 74Wh power bank could theoretically recharge a 40Wh laptop battery about 1.85 times (74Wh / 40Wh). However, real-world efficiency losses (due to heat and power conversion) mean you’ll typically get closer to 70-80% of the theoretical capacity. Therefore, a 20,000mAh (74Wh) power bank can usually provide one full charge to a mid-range laptop and still have some juice left for your phone.
Understanding this relationship helps you choose a capacity that suits your usage patterns. If you have a power-hungry laptop or need multiple charges, look for higher Wh ratings.
