400W portable solar panel

Works great. Need to be very careful with this. Holding rings on panel itself elongate if you allow them to hang some weight.

400 W Solar Panel

Panel Great stand not so much.

The panel itself is a bit bulky (42lbs) if you make a brace it works very well I have gotten up to 385 watts of power. And the panel is robust.

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.

Amazing First Impression !!!

I purchased this item a few weeks ago, but have not had the opportunity to use it yet. I am a novice camper. I can consider myself a first generation camper or explorer in my family. But even though I only have a few camping nights under my belt, I was impressed with the information that I was exposed to online from the reviews of other customers and fellow campers. I really enjoyed the idea of winter camping and I am sure that the solar panels in conjunction with the EcoFlow Delta 2 which I have also recently purchased will be a great combination. I am planning on creating my first YouTube video which will consist in the unboxing of the 400 W solar panel from EcoFlow as well as the EcoFlow Delta 2. As part of a winter camping video series based on New Jersey’s state park campgrounds. I am very eager to see the results of both products. Hopefully, I will inspire other family members to enjoy the beautiful outdoors as well as the different EcoFlow products.
