AIRSPIRIT 400W Folding Solar Panel - ETFE Lamination, IP67 Waterproof for Ultimate Stability & All-Weather Performance (-40°F to 176°F)

I really like this panel. I'm getting 380w at 1:30pm on 6 May in Phoenix. The stands are sturdy and have velcro to secure the panel to it. The case holds the panel and the stands separately. It's very quick to set up and tear down. Comes with adapters in case you're not connecting to solar cables. I quite like this panel

I got this yesterday and needed to try it out befor4e I went camping with it. I have a Bluetti AC180 solar generator and ran the power down to 3%. I setup the panels in the backyard. Not the best of sunny days - many clouds. I moved the panels to follow the sun as best I could. The best output I got was 360w with a 25' cable. it took ~5.75 hrs to fully charge my Bluetti. Considering the cloudy day, I thought it did very well.

PRODUCT REVIEWED: 400W Foldable Solar Panel - Lightweight, Enhanced Stand for Easy Setup, Portable Solar Charger with Adjustable Case, 34.2V Waterproof IP67 for Outdoor Adventures & Power Outages C Upgraded for $499: This folding panel is extremely lightweight for its size and stores neatly in the included bag, which measures 24.4 x 38.3. It is quick to set up for use, with easily adjustable stands that provide 3 different angles for positioning the panel.I really like the fact that there are four standard grommets along each side of the open panel, along with three oval grommets along top and bottom, for a total of 14 potential attachment points. This provides SO many options for attaching the panel to a vehicle or structure. (I could hang it from the rack on top of my camper by the top grommets when it's parked and bump the bottom out with cleverly arranged pool noodles or some other kind of shim to any angle I want.)I bought it to use while camping, to charge my 2000 watt solar generator, and it's great for that. When we're not camping, it will live next to our south-facing deck for quick deployment in case of a power outage. Well-designed, and very useful.

A good sized solar panel that was easy to set up and charges by emergency battery pack without a problem. Very pleased.

Most of the portable panels I have get a maximum power output of about 80-90% of their rated values. Most of the Fixed panels I have give a maximum power outage of about 95% of their rated power outage.Most of the time with these, I am getting about 360 watts, and that is with the fall sun being a little lower than the summer sun I generally use. This works out to about 90%, which is pretty good, except yesterday my Victron showed a power input of 391 watts, which works out to be 97% of it's rated power. Throughout the day, I ended up with 2000 watt-hours of input in my solar systemThe stands are a little flimsy and hard to get aligned, but once they are set up, they do a pretty good job. That said, they are still a lot better than the little piece of plastic that folds out from most of the portable panels.They seemed heavy when I pulled them out of the shipping box, but a lot of that weight is the stands and the case. The panels by themselves are are pretty light and seem to be well constructed.
