What is Max output in watts?

Wattage is how fast a charger or power bank pushes power into a device, and the top figure in a range tells you whether it can charge a laptop or only a phone and earbuds. Output also has to match what the device accepts, so a higher number is not wasted if your device caps out lower. Allpowers reaches 4,000 W and AOHI 310 W, while Anker lists 300 W and MPOW 25 W.
