I bought this to charge my Bluetti V200 and it does a fantastic job. Comes with all the cables you need. In direct sunlight and at the optimal 45 deg angle the best power output I've managed to get is around 320W. Not bad considering I live in PA. I'd say it averages around 250W output. From what what I've read from other reviews (and even from Bluetti's panels) you're lucky on average to get 50% of the rated output of any panel on a regular basis so I'd consider this one a winner!

Works perfect with my Fossibot generator
Reviewed in the United States on June 26, 2025 by Shaun Perkins
Originally gave this product 5 stars, you can read my initial review below. I'm taking off a star because despite all of the straps having a somewhat considerably strong adhesive for the legs, one broke off and I have to prop it up when angled specifically because the other legs get dragged down due to the panel weight and the broken leg being unable to support that weight let alone the other two being dragged down by it. This tear was not even from user error as I share another story with this panel that was my fault below to attest to their actual durability for the panels. The adhesive eventually just wore off and I wouldn't be surprised if it happened to the other legs given enough time. Normally this would be enough of an issue for me to take this down to 3 stars, but I've found myself with time actually prefer either laying it flat or propping it up on rocks or wooden beams and appreciate that you can and that they do not completely restrict your layout for the panels. I have had this product for over a year now and when I first bought it there was not the "frequently returned product" tag, I would keep this in mind and read other reviews as I have seen others put buyer beware tags. I have accidentally folded this panel wrong a few times and it has put up with the wear pretty well, but at times it has also refused to fold back into the original shape with one side (when folded up) being forced out more and was quite annoying. I eventually got it back into the original shape with no permanent damage or less power pull in optimal sunlight conditions. I have gotten sand and gravel residue on the panels, but a simple wet paper towel was able to get it off without causing any damage to the panels which was nice. The plastic clasp that keeps it shut when folded still holds up to this day and allows for easy carrying once completely folded up. I don't face it often, but another thing to keep in mind is even in peak sunlight when you're using a USB-C cable capable of fast charging 60W or above, it can almost lag the USB-A port and take more power through the USB-C cable, again I've only had this happen a few times as devices themselves usually limit their power intake to protect the battery longterm e.g. my iPhone 15 Pro Max only charges at 25-27W at its MAXIMUM rate. It is only when a device like my laptop has a higher charging rate (60W+) that the output for the USB-A is not optimal. This is not to say the product does not pull the intended 100-120W it claims, rather that the USB-C seems to be the one they thought the user would use more, especially with the USB-C changes around the world and it becoming the universal cable. The cables directly attached (non-removable) to the panel itself are nice quality and have been bent in many angles and have held up, however the plastic brick that houses the power and ports is a very cheap lightweight piece of plastic. Regardless, it has held up for me and within the last year has worked when I needed it most, but I know that is only my experience and others can differ. I would still recommend this as a beginner entry into the solar category if you are REALLY interested. Maybe don't get the 100W like I did as a first though, go the 60W route or even lower, especially if size or portability is a major concern for you. Original Review: Comes as another cardboard box protected with styrofoam sliders inside of an amazon box, they do a good job protecting it. Cords are neatly organized inside the zipper portion behind the panel, as well as instructions and a paper for warranty. Cords are straight forward, plug in what you need, boom, done. The USB-C outputs at maximum of 60W so it does support fast charging for phones and charged my 15 Pro Max from 15 to 80 in around 35-40 minutes which was the same as using an outlet so I was impressed. Haven't tested the output with a multimeter, but I do believe it is true to its word of 100W, 120W peak because I have charged my iPad Pro 12.9 inch from 38% to 95% in around 45 minutes and my Oculus Quest 2 from 30 to 71 in about a half hour. In peak sunlight it is extremely efficient like mentioned, and upon arrival when I got it, it was 6PM and the sun was getting low, but I was able to test it charging my Garmin even though the sun was blocked by a tall tree. I managed to get 10% charge on it while in dim low conditions after 15 minutes, which also impressed me. The legs that it has to stand it up are stitched very well and also include velcro to close them up. Folds up easily when not in use and they also include 4 carabiners to hook around the metal rings around each corner incase you want to hang it or attach it to things. There is also a small plastic buckle included when you fold it up to make sure the inside panels do not flop back out and the handles also include magnets to make sure it stays snapped shut. Less than 10 lbs and feels light to carry.

Why did you pick this product vs others?: This 100 watt foldable solar panel was priced much lower than comparable ones, but at the time didn't have as many reviews as the top ones. But it checked off all the boxes of what I was looking for: 100 watt, foldable, a stand, USB ports, and XT60 cable. In full sun, I'm getting 70-80 watts. You might get a little more with the perfect angle and perfect conditions, but 70-80 watts is reasonable for foldable panels and this price. I like the included pocket for the cables and adapters. The build in stand is a little flimsy and takes some work to stand the panels up. The outside fabric material can easily get dirty if you're setting it on the ground, especially during camping.

This 100 watt portable solar panel was able to charge everything I plugged into it. I plugged in my MacBook, then my iPhone, my iPad and two power banks (all separately) and it was able to charge each device without any issues. I will say that it is a bit unwieldy to try to deploy because you have 5 folding panels that are all flexing as you are trying to stand it up. The kickstands, which fold out from the back are a nice addition but they tend to fold back up while you are working on standing up the next section. It took several minutes to balance it and keep it standing upright but this is just a side effect of having a folding solar panel and really shouldn't count against it as it does what it is intended to do, which is to charge up your devices using the sun. I got this to use in a power outage and based on my tests, it works well

We used this panel over the weekend either our Geneverse solar batteries. It worked great! It is really long - i didn't pay attention to the dimensions when I ordered it. We use the panels/batteries with our 1974 Sprite Camper. I typically put the panels up on the roof. This one hung off of edge of the curved roof by about 4" on each end.
