We've had this 400 watt panel for a few weeks now and love it. We previously had two of the 220 wats bifacial panels and loved them but this one has been a game changer for our charging ability.

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.

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.

I set mine up on the roof of my house and use a 20ft extension. It hasn't moved even during storms. I have one of the early Delta models, and it works great. I just need a bigger battery. As the sun first rises, I only get 20-30 watts and peaks over 300 watts around noon. Considering the panel isn't pointing directly at the sun, I'm impressed!

Case standing system awkward and difficult, folding leg on panel would be much easier.

Haven,t been able to use the solar panels until I can get some extension for these panels.

We use this solar panel to recharge the Delta Max 2 instead of using a/c power, takes longer but it's free power

Great panels. These panels were an upgrade from the 160W versions. These pull in so much more power for the EcoFlow.

I've now got a full set of 400w panels. Four to be exact, heavy duty, precision made, quality thru an thru. Charges my battery packs quickly. Portable and easy to deploy.

Fast Charging! I like my 400W Solar Panel. It charges my Delta Pro much faster that my 2 X 100W panels. It is a little big and heavy for one person to set up but I have gotten used to it.
