Big. Fairly heavy….but yea, portable. Panel Flexes back a bit when using the case as the stand (all there models do, I have the 400, 220, 160, and 110s). Typically get 300 watts laying flat and not adjusting. Happy enough about that. Running two in series I have seen 650 as a high, again flat and not accounting for tilt and angles (and they are fairly dirty).

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!

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.

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.

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.

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.

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’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.

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.
