The battery announces 20,000 mAh for 3.7 V, but it takes 15,745 mAh following conversion to 4.7 V. A capacity which is actually a little lower according to our tests, since we noted 14,150 mAh. A difference of 10% which therefore remains very contained.
As it stands, the battery is capable of charging a Samsung Galaxy S22 almost 4 times and the latest 12.9-inch iPad Pro more than 3 times. A great ability!
Given its large capacity, it takes 3 h 40 min to fully charge this Mi 50W Power Bank 20000. It’s quite long, but on average for 20,000 mAh batteries that have passed through our laboratories.
