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%.
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.
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.
The case to be used as a stand is a joke. I couldn't get it to work for me at all. I opted to just lay the panel flat on my back deck. The sun hits my deck from around 9am until 6pm. It is July so I'm sure that will change, but for now it is working for me. With all that said and done, I still am able to produce up to 310watts. I'm very happy with that. My TV, and my gaming laptop and 2 fand and 2 phone chargers only pull 170watts. So I am able to game and charge other items and have no worries of using more power than I am producing..
I tried out this 400W solar panel with one of my Delta Pros yesterday. It was a partly sunny day, so the wattage input varied greatly. However, I was able to get up to 367 W of input at one point, and was able to charge from 30% up to 61% within an afternoon. I’m happy with that!
My condo in the city is now mostly off grid. Wild.

It's more than enough power to run my kitchen from my south-facing balcony in California. And that's wild. We are making power plants irrelevant. It's a whole new world.
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 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.
