What to know before buying
Listing details to confirm
The listing's title and details give a 500W rating, while another details field lists 1000 watts as maximum engine power. These figures are not explained as continuous versus peak output, so verify the intended rating before relying on the higher figure. The headline says wireless charging but does not specify its wattage there, while the feature details specify 10W. Recharge times are listing estimates and solar time depends on a compatible panel.
