The Renogy 400W Portable Solar Panel is a folding solar blanket built for camping, van life and emergency backup. It uses N-type cells and puts out about 400 watts at 33.6 volts and 11.9 amps, enough to charge a power station or a 12V battery bank through a compatible charge controller. It folds into a compact package, so it travels far more easily than rigid panels of the same output. Against rigid 400W panels it gives up some efficiency and durability, but it sets up in minutes and needs no mounting. Owners like the output for the size; the main complaints are weight and the need for a separate controller on many setups.
