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. .

You know how you bump elbows with someone on the sidewalk and they put a little brainstorm in your head, well thats what led me to buying the Delta Pro and the "Extra Battery" .. I use it exclusively for charging my Tesla (I don't have a garage, or access to electricity in my carport) .. Perfect solution for everyday driving for me ...

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.

Great panel with performance that out shines other 400 watt panel systems. EcoFlow backs up its products with excellent customer service and rapid feedback on any questions or issues. This is the solar panel to buy for its ease of mobile deployment, power, and durability.

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.

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.

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.

I wanted to be sure I had more than enough power going into my Delta Pro and Extra Pro Battery, especially if I am on the move or need to power my 3D printers for an outdoor event. Leaving the panel out in prime sunlight made it charge the batteries as I was 3D Printing. This means I was 3D Printing with ZERO CARBON EMISION! That's amazing!! I'm seriously considering making my whole business run on ECOFLOW Batteries and Solar Panels from this one experience alone.

I bought 2 large EcoFlow batteries on their website but they were sold out of the 400W solar charging panels. Found out Wall Mart had them so I ordered it through them for a great deal. I was nervous about buying from two separate places about compatibility and whether all the connecting cables/cords would be included. Turns out everything was included, compatible and it worked like a charm. My batteries were both less than 50 % when they arrived and the first thing I did was put it out on the deck and charge them both with the solar charger to full charge in about 4-5 hrs. I was worried about how bulky and heavy the solar panels would be for this size of a charger. It wasn't bad at all. Everything folds up nicely and the carrying case works well. Love it !!
