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

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.

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!

Great value! Seems like a really solid panel! Haven’t had it for long, but the build quality feels excellent. Fits perfectly in my RV and charges my anker solix quickly.

Very impressed! I know solar panels don’t usually reach their full rated wattage in real-world conditions, but this 440W SolarBag consistently gave me about 340–360W in testing — way better than I anticipated. They included a usage guide after purchase, and it turned out to be super helpful. A few key takeaways that really improved performance: 1. Test it around midday in clear sunlight. 2. Make sure the entire panel stays in direct sun — even small shadows cut output a lot. 3. Connect the two panels in series and double-check the plugs are tight. 4. Output will vary by season and your latitude — the reference chart in the guide explains it well. With those tips, it runs like a champ. I’d definitely recommend this to anyone looking for a reliable portable solar option!

I tried this with my RV, and it’s been very handy. Instead of a big, heavy panel set that takes up half the storage space, this one folds neatly and rides in the side compartment. Once parked, I can spread the two panels separately to catch the best sun. It handles multiple outputs without slowing down too much. I had my laptop and tablet charging on one side while topping up a power station on the other. It’s efficient without being complicated. Having quick USB ports right there on the panel makes it simple—no digging around for extra cables.
