The main thing that makes SuperMini stand out is its physical size. It uses 21700 Battery Cell,each Cell has capacity of 5000 mAH
It’s 3.1-inches long, 2.2-inches wide, and 1-inch deep. In addition to being quite small, it’s also pretty light, tipping the scales at 6.35oz. It’s about an inch smaller than typical 10,000mAh power banks on the market in terms of length, which makes it quite a bit easier to carry around in a pocket.
As far as outputs, there’s both USB-C and USB-A, and both feature 18W of power delivery. In about 30 minutes, the battery pack can charge an iPhone XS to about 50%, which is pretty solid. Additionally, the battery itself will reach a full charge in about three hours, so you won’t have to wait too long to get it back on the go.
