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.
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, so you get even more energy to recharge your portable power station.
Take solar power on the go. EcoFlow’s 400W solar panel is a camping or RV must-have. The compact design saves valuable space for your other travel essentials. When you’re ready to head off on your next adventure, simply collapse the panel down to store in your van or car.
Capture more rays. Made using highly efficient monocrystalline silicon cells. And with an exceptional energy conversion rate of 22-23%, you get more energy with every cell. Plus, when connected to an EcoFlow solar generator, the Maximum Power Point Tracking (MPPT) algorithm auto-adjusts, guaranteeing a constant and stable power supply.

Exclusions and Limitations
This warranty does not apply:
Cross-Regional After-Sales Service
EcoFlow does not provide a global product warranty, and the warranty service can only be obtained at a designated EcoFlow repair center.
To repair the product in an EcoFlow repair center when the product was purchased in another region, depending on part availability, customers can obtain a cross-regional repair service at an additional charge. (Some products do not support cross-regional repair even if the customer is willing to pay for the service. For more details, please contact EcoFlow Support.)
A cross-regional replacement service is not available for different versions of the same product.
The customer will need to bear customs duties, taxes, customs clearance, and other costs incurred for a cross-regional repair, regardless of whether it is the warranty or paid repair service.
