EcoFlow 400W Portable Solar Panel
Our 400W portable solar panel offers high solar output, conversion efficiency, and a convenient folding design, making it ready to grab and go at any time. Pair two 400W portable solar panels with your DELTA 3 Plus, which supports up to 1000W solar input, to ensure you’re fully powered up, no matter where your adventures take you.
Charge Faster, Wherever You Go
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, giving you even more energy to recharge your portable power.
Built to Weather the Storm
Our 400W portable solar panel can keep collecting energy even during a downpour. With a protective ETFE film and a high IP68 resistance level, the solar cells can withstand environments from humid and wet to dry and dusty.
