My son has been on a nationwide camping trip, and he was tired of needing to buy ice for his cooler, so I got him a car refrigerator, a power bank with an additional external battery, and this solar panel. This was one of the least expensive panels, so I had my doubts about it, but figured it was worth a try anyway. I gave all this stuff to my son for Christmas, and we set it all up. The power bank kept the refrigerator going with no problems, after running overnight, it was down to 90%. We were going to hook up the solar panels, but it was cloudy, so we waited until the next day. The next day we did have some sun, so we hooked it up and found it was pretty easy to get 150 watts out of it, but it was still partly cloudy,,, then it got very cloudy... it turned out to be a whole stream of cloudy days, and the power bank got down to 54%, but then our luck changed, and we got a relatively sunny afternoon, and the power bank was able to get charged up to 82%, and this is while the refrigerator was always being powered. Then the next morning, Finally, we had a perfectly clear day, not a cloud anywhere, by then the power bank dropped to 73% overnight, we set up the panels a little after noon, because there are a lot of trees, and I was shocked to see this panel was producing 198Watts! Keep in mind this is in December, just a few days after the winter solstice, the WORST day of the year for solar panels, because the sun is at its lowest angle. I went back to check on it in 2 hours to re-align the panel, and I was again surprised that it reached 100% so fast!! So, he went an entire week with mostly cloudy days, and was able to still get a full charge on one good sunny day! Getting power readings of 198Watts in December is good enough for me! This panel is very easy to deploy, and it's easy to align. The wires it came with were too short and had the wrong connector, so I just bought a cable with the right connector on them, and even with the other cable, it was still more cost effective than other panels.The only issue we had it is that the kickstands like to re-Velcro themselves back in place, and that can be annoying, it would be better if they had a Velcro strap go across the kickstands so you could release them, but they couldn't re-attach themselves, but my son quickly learned how to deploy the kickstands as he set it up so they don't re-attach. I also got him a 20 foot 10 Ga solar extension cord, a tool to disconnect the solar connectors which can sometimes be difficult, and a solar alignment guide. Note that the 198watt reading I observed was before I even got the solar alignment guide.My son took this whole setup with him on his road trip, and since his car charges the powerbank while he's driving, he didn't need to charge it until he got to a place he was going to stay for a few days, then he set it up and he was easily able to get charged back up to 100% in just a few hours every morning, and maintain 100% all day, so his batteries for the power bank are only needed overnight. This solar panel folds up nice and small and has a zipper pocket on the side to keep the cables and alignment guide stored.I'm really happy with the price and performance of this solar panel, and I highly recommend it!

Workmanship is good, throws out 330w on a hazy day, size and weight is average. I expect to see 370w on a perfect day. Very fast delivery. Seller was very responsive when I asked for expedited shipping. Would buy again so far.

In full sunlight I can only get 135 watts

Use this on the motorhome Dash to charge the chassis battery when parked, seems to work okay

What makes this solar panel great is its size and weight. Most 200W solar panels are too heavy and large to store in a car trunk for a country drive. I've used it to charge my Anker powerhouses, and the highest output I've seen is 175 watts, typically staying in the 160s. Considering its size, weight, and sale price, it’s perfect for my needs. It's well-known that solar panels rarely produce their stated output; getting 80% is often lucky, so this panel’s performance is impressive. I bought another one, and now I can charge my devices at over 300 watts. I also have a 400W panel that produces about 320 watts, but it’s very expensive, heavy, and large—even though it’s foldable, I’d need a van to transport it. Two of these smaller panels are lighter and the same size as the 400W one but are much more portable since they come in two pieces.The best part is that even when the sun is covered with clouds and it looks like rain, it still pulls about 40 watts, which is impressive. Any tiny bit of light will generate charging power. I’ve even used a bright flashlight on the panel, and it turned on as if it was ready to charge.Additionally, the customer service is excellent. I had many questions and probably annoyed the seller, but they answered all my queries within hours. The response was super fast, extremely helpful, and patient. Highly recommended.

I really needed this to charge a Jackery 1000 battery during recent frequent and sustained grid shutdowns due to high winds in Southern California. Unfortunately even in bright direct sunlight it gave zero input when plugged into the battery, so it was returned for a refund.

Portable solar power to recharge my batteries. Tested and got very near the power specs. Unit when folded was a little heavier than I expected.

This solar panel is light weight and has a superb quality build. I have owned several of these panels and none are as compact and built the way this one is. It is highly efficient,and can charge my solar generator quickly.Easy to use and easily packs with a pouch for the assessories.
