The most powerful portable solar panel on the market. If you already have or plan to buy an EcoFlow power station DELTA, DELTA MAX, or DELTA PRO, these will pair exceptionally well with the 400W Portable Folding Solar Panel.


Portable & Lightweight: With an input of 400W, this is one of the most powerful foldable solar panels on the market.  Weighing only 16 kg, the lightweight design and built-in shoulder strap make it ideal for outdoor adventurers. 

Self-supporting: The protective case conveniently turns into a stand that adjusts from 40 ° to 90° allowing the solar panels to be set up at an advantageous position to the sun. 

Robust & Weatherproof: Made from layers of pliable EVA and durable fiberglass to combine the versatility of flexible solar panels with the strength of rigid ones. Each monocrystalline silicon cell is covered with an ETFE film, protecting against dust, particles, dirt, and water. With an IP68 waterproof rating, the portable solar panel works in all kinds of weather, making it perfect for both camping and rooftop use.

Wide-ranging Compatibility: The panel features the universally recognized MC4 connector, making it compatible with all EcoFlow DELTA Series portable power stations and many other third-party generators.

Smart Solar Energy: The EcoFlow 400W solar panel has a conversion efficiency of 22.4%, and when paired with an EcoFlow portable solar generator, can extract the most energy throughout the day. The solar generator adjusts its efficiency using the Maximum Power Point Tracking (MPPT) algorithm, to deliver a constant power supply.

Two years' manufacturer's warranty.
