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 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.

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.

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.

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.

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.

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.

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 all connected together and cannot be separated. The solar package is heavy and awkward to handle. They put out their rated watts and charge the battery very well. But do not lay them on your grass lawn as they will kill the grass.
