Our 400W portable solar panel offers high solar output, conversion efficiency rating, and a convenient folding design so it’s ready to grab and go at any time.
 
A single solar panel with a unique folding design, our 400W solar panel combines powerful energy production with portability. To achieve a higher solar conversion efficiency of up to 23%, we use multi busbar monocrystalline cells, so you get even more energy to recharge your portable power. 
 
 EcoFlow's 400W portable solar panel comes complete with a protective case that doubles as a sturdy supporting stand. Simply set up your panel anywhere and conveniently adjust its angle to get the most sun possible. 
 
Made from durable and flexible materials, the portable solar panel is perfect for off-grid living and travel. Its multi-layered design offers high impact resistance for the rugged outdoors, while its 27.5 lb light-weight means effortless carrying to a campsite. A rigid layer embedded in the carry case protects the panel from overbending when you carry or store it.
 
 Our 400W portable solar panel can carry on collecting energy even during a downpour. With a protective ETFE film and a high IP resistance level of 68, the solar cells can withstand environments from humid and wet to dry and dusty.
