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.

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. .

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)

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.

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.

I am very impressed with the Echoflow foldable solar panels. Well made, meets or exceed all specs. I like that the panels are built for the Echflo pro product and I don't have to gerry-rig 3rd party solutions..Be aware that they are soldi built which makes them heavier than other similar panels.....just goes with the territory if you want quality..........In-addition.....I am always impressed with the customer support EchoFlow provides....I know I can always get an answer to my questions either through customer support line or the EcoFlow Delta Series Group, face book page ..I highly recommend all of the Echflow product and anxiously waiting for new products that can augment my home power needs..... thank you very 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.

I hooked up the solar panels to the charger today. The panels and charger are on my in full sun. Started at 29% battery and now is at 42%. Charges at a slower pace. It’s been charging for about 2 hours. I have four panels for 400 watts.

Very easy to set up and put away. A bit heavy but there's not much to be done about. The only reason I care about the weight was thatbI planned to doublenit as an awning on my van, but thebweight makes that impractical. Does everything its meant to.
