Two figures describe a power station and they answer different questions. Output in watts is what it will run at once, and it has to exceed the draw of whatever is plugged in. Stored capacity is how long it will run for, and the two are independent of each other. Both figures appear on every listing precisely because neither answers the question alone.
Getting that wrong in either direction is a common error. A high output station with modest capacity runs a demanding tool briefly. A large capacity station with low output will not start that tool at all, however long it would have run it. Charging and lighting draw very little; a grinder or a compressor draws a great deal for short periods.
The range runs 300W, 600W, 1800W and 3000W, which spans charging and lighting at the low end and running tools at the high end. A 140W power bank at 27000mAh sits below all of them for phones and small devices rather than equipment. A 3000W station covers most site tools where a 300W unit covers a laptop and a light.
Solar bundles pair a station with a foldable panel so it recharges away from a supply, at 110W ETFE panels with the 300W and 600W stations and 220W panels with the 1800W and 3000W.
