If you always replace your phone with a newest one, it might be worth looking out for a more powerful charging power bank that will support future devices. And get one with a more powerful wireless charger won’t hurt your lower rated devices, which will charge your devices with the most suitable speed.
- Wireless Charging Power
The official recommend wireless charging pad for Samsung Galaxy S9 can provide 9 watt wireless charging power. Therefore, if you don’t want to take a long time to wait for your S9 been fully charged, you should choose a wireless charging power bank which can provide charging power around 9 watt.

Common sizes of power banks range from 2000mAh up to 26000mAh or even larger. Larger capacity means more power and more recharges for your S9, but bigger body size. Therefore, choosing a suitable battery capacity is most important. Samsung Galaxy S9 houses a 3000mAh battery inside. You can decide to refer to the frequency of power bank’s usage. If you just need to recharge it three times a day, 10000mAh power bank will be the choice.

Sometimes, you will use power bank to charge other devices which don’t support wireless charging. Therefore, the output ports on it are also important. The number and feature of power bank’s ports are various. Power outputs vary as well. For S9, the quick charge port is definitely needed. How to quick charge Samsung Galaxy S9
