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 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 !!

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.

Excellent Solar Panel, very good power output... when I tested, I was getting about 350 watts out of each panel, all without even trying hard to get the angle right. Would definitely recommend.

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.

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.

Works OK, a little heavy and I wish it away to stand it up at an angle, I havey another power station and the solar panels have some brackes that let you stand the pannel up.

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.

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.

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.
