Purchased the VTOMAN VS220 19V in mid-February. First brief trial test connected via XT60 to my EcoFlow River 2 Max yielded 130-160 watts on a mild mid-February day, the Sun behind high thin clouds, then in full Sun, a consistent 200 to 220 watts, mostly 220, as claimed by VTOMAN. Very pleased with that. Appears to be well designed, durable constructed, and a good looking panel too, building confidence that it will provide many years of reliable service charging up my power station on my travels and camping/dry camping trips.
