This is Solar bag is fantastic and far more compact than my other solar suitcase panel. It’s perfect for over landing where things can get daily tight when I have a lot of gear. Even when I am in a tight camp sight. I can toss this up on my windshield and hood of my vehicle, but it works just as good lying flat on the ground. Best that is. It’s light weight, easy to carry around and let’s you split the panel in two charge multiple

I take this panel with me everywhere—camping, picnics, even just out in the backyard. It folds up compact, unfolds in seconds, and charges my power bank faster than I expected. Being able to split it into two panels is a bonus. Really happy with this purchase!

This foldable panel is my go-to for backup power. It’s lightweight, stores easily, and performs really well when there’s good light. I also love that you can split it into two separate panels—such a smart feature. One thing to keep in mind—it’s not shadow-proof. If even part of it is shaded, the power output drops big time. So be sure to set it up somewhere clear and sunny. Other than that, it’s been totally reliable!

got this Optisolex 400W panel to see if it could actually hit anywhere near its rated output—and honestly, I was impressed.I tested it with my own solar meter, laid it out across the windshield on a sunny afternoon, and it was pulling about 390W. That’s pretty solid for a foldable panel.It’s lightweight and folds down to about the size of a backpack, so it’s easy to carry and stows away nicely in the back of my car. Definitely way more compact than the rigid panels I’ve used before. I’ve taken it out on a few trips now, and it’s been super easy to set up and charges my power station quickly. So far, it's outperformed what I expected.

The media could not be loaded. Day 1 typical camp site where portable power would be used with shade was getting 11 one one watts see video Day 2 I moved to where you can't park on the boat ramo so I can see if any better, What company that cares about anything sends stuff out that's not usable, add a 10 foot extension cable on the scale you would buy less than 1 dollar, but no use the cord the reaches 3 inches, out of the blanket. Moved to full sun not seeing over 300 Now I left the box back in New England and I'm in Texas so hopefully I can drop it without a bot at a staples. No pride in anything anymore so sad

This is a high-quality 400W suitcase-style panel that is lightweight and easy to move around and set up. I was especially impressed with the customer service—I asked if it was compatible with my ecoflow delta power station, and the seller quickly checked and confirmed compatibility. They even sent me a detailed list of supported power stations for reference, which was incredibly helpful! According to the information provided, the 440W SolarBag works well with a wide range of brands like ecoflow, bluetti, jackery, anker, and more. It’s reassuring to know it fits so many systems.

I’ve been using the Optisolex solar panel and it has really impressed me. It’s very light, simple to carry around, and pairs perfectly with my Bluetti power station. Setting it up or moving it from one spot to another is no trouble at all. Depending on the sun and weather, it provides strong, reliable power, and I’ve been more than satisfied with the results. On top of that, their customer support has been outstanding—quick to respond and very clear in their answers. Overall, a great product and experience. Definitely recommend it!
