The RSP400SB is Renogy's 400 W folding solar blanket, a 16.09 lb fabric panel with MC4 output that can run partly unfolded at 300, 200 or 100 W. At 400 W it reaches the top rung for a portable panel, so it scores 10 on capacity.
It suits a camper who wants 400 W in a 16 lb backpack rather than a 30 lb suitcase, and who has 2.64 m² of ground or windshield to lay it on and no need for a stated output guarantee.

The Renogy 400W N-Type Portable Solar Panel Blanket (RSP400SB, current build RSP400SB-G3) is a folding fabric panel rated 400 W at STC, with 33.6 V and 11.9 A at maximum power, 39.2 V open-circuit and 13.1 A short-circuit. It unfolds to 64.96 x 62.99 x 1.50 in, folds to 16.54 x 15.83 x 4.13 in and weighs 16.09 lb by Renogy's manual. Renogy says it can run partly unfolded at 300, 200 or 100 W. Output is MC4 only, with no USB ports, and the 39.2 V open-circuit voltage needs a station or controller input that accepts it. The manual describes TOPCon monocrystalline cells and Renogy advertises 25 percent cell efficiency; the panel's own area works out to 15.2 percent. It is rated IP65 splash-proof for -10 to 65 °C, and the manual warns against rain and long use in humid conditions. Loops on all four sides take carabiners for hanging, and two shoulder straps carry the folded pack. Renogy covers it for 2 years on materials and workmanship and publishes no power-output warranty.
