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.

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. .

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).

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.

The solar panel works as it's supposed too. Gets close to the wattage, if placed correctly in the sun. Charged my EcoFlow Delta within 3 hours from 50% on a sunny and warm day. I did have an issue with the kickstand and had to prop it up using outdoor furniture, but I'm assuming that was user error. :-) One of the accessory hooks broke, but they replace it very promptly.

Solar panels are great and provide faster charging than I thought they would. They are extremely heavy however and I was unable to move them around well. Also, they are floppy and it is difficult to easily reposition them for sunlight. If you are not very strong and small in stature, you should consider a smaller panel set.

[This review was collected as part of a promotion.] Walmart has the best price on these. They undercut Ecoflow and Amazon by about $150. The folding frame is junk so you'll have to make your own. I used pallets with the panels screwed down. Then prop them up to the angle you want. Now for the good part. In full sun, these panels consistently put out 380 - 405 watts! I have not seen any other brand come so close to their rated value. Usually you get about 75% Spend a little more and only cry once.

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.

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.

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)
