The EcoFlow 400W Portable Foldable Solar Panel has been outstanding. It delivers strong, consistent power in good sunlight and pairs perfectly with EcoFlow power stations. Setup is quick, the folding design is convenient, and it’s easy to reposition to track the sun.

Build quality is excellent—sturdy materials, solid connectors, and it feels made for outdoor use. Despite its size, it’s manageable to transport and stores neatly when folded. This panel has been a reliable way to recharge during outages and off-grid use.

If you need serious portable solar power, this panel is worth the investment. Highly recommended.

Powerful, Well-Built, and Easy to Use

walmart.com

Hoked up a single 400 watt panel. I live in orlando florida so sun is always available 
With some adjustment it was pushing 300-325. I purchased a second panel but havn't tried them in series yet.  I hope to get 600-700 watts.  I think it will do the job with an extra battery.  
.

Great so far

ecoflow 

These panels have far exceeded my expectations. I use these panels in conjunction with my Honda ES2200 to charge my Ecoflow Pro which in turn supplies power to my RV Trailer. The panels typically supply 250 to 275 watts on a sunny day leaning against my trailer. When laid out more flat to the ground I've seen as much as 380 watts.
These panels are heavy and a little pricey, but I believe it's money well spent and plan to purchase at least one more set..

More than i expected!

This pane has been my go to panel when charging my devices. i average around 375 t9 384 watts which is very good. i now own three of these panels and i would highly recommend them to anyone looking for a large foldable panel with this much solar output. Do not just take my word for it try one and see why I love this panel so much.

EcoFlow 400W Portable Solar Panel

Big. Fairly heavy….but yea, portable. Panel Flexes back a bit when using the case as the stand (all there models do, I have the 400, 220, 160, and 110s).  Typically get 300 watts laying flat and not adjusting. Happy enough about that. Running two in series I have seen 650 as a high, again flat and not accounting for tilt and angles (and they are fairly dirty).

400 watt panels

I purchased this item a few weeks ago, but have not had the opportunity to use it yet.  I am a novice camper. I can consider myself a first generation camper or explorer in my family.  But even though I only have a few camping nights under my belt, I was impressed with the information that I was exposed to online from the reviews of other customers and fellow campers. I really enjoyed the idea of winter camping and I am sure that the solar panels in conjunction with the EcoFlow Delta 2 which I have also recently purchased will be a great combination. I am planning on creating my first YouTube video which will consist in the unboxing of the 400 W solar panel from EcoFlow as well as the EcoFlow Delta 2. As part of a winter camping video series based on New Jersey’s state park campgrounds. I am very eager to see the results of both products.  Hopefully, I will inspire other family members to enjoy the beautiful outdoors as well as the different EcoFlow products.

Amazing First Impression !!!

Worth every penny.   This solar panel has changed the way I use my EcoFlow max.   amazing working art.  It even gives me 370 watt in day cloudy day.  My  generator is always 95-100 topped up. During the day.  Just need a little bit of light and they power up.  Highly recommend.   I don’t get paid for this survey and not sponsored.   My personal experience.  They deserve 5 star.  I ordered my 2nd 400 watt panel.

EcoFlow is the future

We have a class b camper van.  On a recent trip during the summer heat wave we put out our 400W solar panel connected to our EcoFlow delta 2 and then plugged in our RV.  Charged our delta 2 as well as our house batteries.  We had all the juice we needed.  The panels were heavier than i like but were manageable and well made.

Great-right out of the box

Purchased this unit (DP) to act as partial backup to home using the EF 400W portable panels.  The initial base line testing has been completed and the unit performed well.  Will have final verdict after a few more weekend tests. 
The solar panels seem well built.  The dual purpose kickstand is a little tough to use and does not show good value unless conditions are ideal (which is almost never the case)

EF 400W

Ordered it as soon as it became in stock again. Took a while as it shipped from Hong Kong. Packaging was damaged but luckily the panels were not. The panels are heavier than I thought they would be. Works very well to recharge a standard delta unit - generating max of 200w by lying flat in morning sunlight. Took about 1 hour to go from 86% to 100%.
