If the power bank supports Samsung’s Adaptive Fast Charging (15W), it can charge your S9 from 0% to 50% in approximately 30 minutes, similar to the wall charger. A full charge from a fast-charging power bank could take roughly 1.5 to 2 hours.
If you use a power bank without fast-charging support, or with a lower output (e.g., 5W or 10W), the charging time will be significantly longer. A standard 5W charger might take 3-4 hours or even more for a full charge. It’s also worth noting that the power bank’s remaining charge and the efficiency of the charging cable can influence the overall charging speed. Using a high-quality, certified USB-C cable that supports the power bank’s output will ensure optimal charging performance.
