Excellent Solar Panel

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.

Solar Panels need a stand

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.

Great-right out of the box

We have a class b camper van. On a recent trip during the summer heat wave we put out our 400W solar panel connected to our EcoFlow delta 2 and then plugged in our RV. Charged our delta 2 as well as our house batteries. We had all the juice we needed. The panels were heavier than i like but were manageable and well made.

More than i expected!

These panels have far exceeded my expectations. I use these panels in conjunction with my Honda ES2200 to charge my Ecoflow Pro which in turn supplies power to my RV Trailer. The panels typically supply 250 to 275 watts on a sunny day leaning against my trailer. When laid out more flat to the ground I've seen as much as 380 watts. These panels are heavy and a little pricey, but I believe it's money well spent and plan to purchase at least one more set..

The Power of The Sun Charging My Business!!

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.

EF 400W

Purchased this unit (DP) to act as partial backup to home using the EF 400W portable panels. The initial base line testing has been completed and the unit performed well. Will have final verdict after a few more weekend tests. The solar panels seem well built. The dual purpose kickstand is a little tough to use and does not show good value unless conditions are ideal (which is almost never the case)

Convenient and charge quickly.

Solar panels are great and provide faster charging than I thought they would. They are extremely heavy however and I was unable to move them around well. Also, they are floppy and it is difficult to easily reposition them for sunlight. If you are not very strong and small in stature, you should consider a smaller panel set.

I love it, but it is very heavy, but I will buy other solar panel.
