Could be better.

I love the wattage output but you cannot get its full capacity with the length of the legs. The panel needs to be able to stand up a little straighter because the sun might be lower in my cause. Its really heavy so finding something to lean it up on is sometimes difficult. Can't wait to see what improvements are made in the next version.

Big Portable Panel

Very large portable solar panel delivers. I have used it for a few weeks now and have gotten great results. It has delivered over 300 watts to my portable generator topping it off very fast. It is heavy and a bit of a struggle to set up but well worth it.

Charles Whitlatch
Tested Out Fine and Seems Like a Very Good Value

I was easily able to get almost 300 watts output after just a quick test so I feel confident the panel is a good value. I did have some trouble setting it up by myself as it's pretty long and floppy while trying to deploy the supports. It's also a little heavy for me at age 76. Other than that, it seems to be a good performer especially at the price I paid and it stores compactly which is one of the main reasons I purchased it.

Amazing panel, great quality and generates a lot of power

The Allpowers 400W panel is a large panel for gathering a significant amount of power. It is foldable and portable but it's bigger and heavier than traditional panels because, well it has to generate 2-4x the power. It is great however for camper vans and off grid living. The panel will quickly replenish your portable power station, it'll keep it charge up during the day and make sure you don't have to worry about running out of juice.
