    • Nice and light weight.

Works great and very light weight. Will see about longevity.

    • Durability
Size: 400W
The solar panels are great. They are well made. The case that they come with is outstanding. They're not overly heavy. They have some weight to them because they are well made and there are a lot of panels for a good charge.

    • A great way to use the Sun
Size: 400W
A nice way to never have to charge your battery pack. With this I get around 300 w and it can charge my battery pack around 40% in one day I paid around $300 for this. I think it's well worth it

    • Good output
Size: 400W
Ok so I’m pleased with this, but didn’t give 5 stars due to one thing.. these panels slightly delaminate when opening/closing. I just rub it down with my finger every time after opening to try to avoid further damage. With that being said I got 350 watts from it, but 270-280 on average-06/04/2026

Amazing value for the weight! Ultra fantastic charging. Using two for my delta 3 max plus, I’ve gotten as far as 720 wattage. Charging a delta 3 max plus with its smart battery attachment from 40% to 100% in about 4-5hours? Yes sir! Excellent functionality. Make sure you buy one of those $10-$20 handheld plastic sun anglers (look it up on Amazon) so you can precisely aim this at the sun and you will get the most wattage. If the company the created this, can this same amount of wattage in 10lbs and less panels → I’ll gladly pay more! ... show more

    • You won’t get 400 watts.

Review Image by J. Henry
It works, but it’s a bit of a pain. I have a couple issues with this product, first, it is quite flexible. The whole thing. The supports are flimsy and once unfolded, this thing is 12 feet long (!!) which makes using the flimsy supports on each of the 6 panels very fiddly. When you adjust one support, you’re extremely likely to mess up or collapse the supports on the neighboring panel. As far as power output goes, I am disappointed. My only other solar panel is a 100 watt panel from Harbor Freight, which I had previously been using to recharge my Anker Solix C1000. Per the display on my Anker, I have gotten as much as 113 watts, and generally in full sun, 106-108 watts out of that harbor freight panel. Imagine my disappointment when I’ve only ever seen a max of 302 watts from this supposed 400 watt array. Yes, they are set up in the same place. Yes, the comparison between the two happened at the same time of year. And I’m in Las Vegas, so the sunshine is pretty consistent here. To recap: I have a budget panel rated at 100 watts which consistently outputs more than what its rating says and I have this $300+ unit that can’t even come within 100 watts of its rated output. I mean, it seems like it’s built well, and even at 275-300 watts it does keep the Anker topped off pretty quickly, but if I had it to do over again, I’d skip this product. ... show more

    • I will buy again.
Size: 400W
Awesome 400 watt folding panel. The only downfall is keeping them clean. They definitely have to be washed with a damp cloth before they get hot. From everyone who's had a problem setting, I have not had a problem with setup. It only takes me a minute. Start with the two legs in the middle and work your way out. I will definitely buy more of these. ... show more
