I bought this to replace 2 goal zero 20 watt panels that both mysteriously stopped working within about a month of each other. I had them chained along with a nomad 13 and 7 for a supposed output of 60 watts, though I think 33 watts was my highest output from them according to the guage on my yeti 400. Possibly line droppage had something to do with the lower numbers since there was about 6' of cabling between each set of panels.I've had these panels for about 2 1/2 weeks now and am really pleased. My highest output from them has been 43 watts so far. I get a steady 12(ish) watts during overcast weather, whereas the gz 60 watt combination would get maybe 5. Pretty much the same results for both when laid across my dashboard.I don't know the full potential of these panels since my batteries have been maintained at 80% charge or above since I received them. The first day I used them it was a bit overcast so I was never able to see their full output on a battery below 40%. Thats low enough that the charge controller on the Yeti 400 would basically allow as much incoming wattage as it was receiving. That first day brought me up over 80Ùª and it hasn't been much lower since then.These panels have zero problem keeping my yeti(s)150 and 400 fully topped off.They seem sturdy and so they are a bit heavy. Probably not the best choice for things like backpacking or hiking but a definite "should have" for your vehicle in case you get stuck somewhere. Charging a phone or tablet, even in moderately cloudy conditions, would be no problem at all.I would recommend to the manufacturer that they include a few grommets or other types of attachment points along the sides. I use these in my van, which has a small rain gutter running around the perimeter of the roof. That rain gutter is a perfect spot to hang solar panels from, via carabiners, during fall through winter months when the sun stays low over the horizon even at midday.I would definitely recommend these thus far.Edit/addition: So, it's rare that I'm so happy with a product that I add to my initial review.That said, I've had these panels for 5 or 6 weeks now and I'm probably happier now than when I posted my initial view.I could probably add another large battery into the mix and still end up with them all fully charged a vast majority of the time.These panels blow my old goal zero panels out of the water for much less money!I haven't rain tested them yet (and probably won't) but even through gloomy Seattle weather they collect a respectable amount of power.I also have not tried to see if I could pull in more than the 43-44 watt peak I saw after I first received them, simply because the batteries they are charging have not gotten low enough to ever allow that much incoming power.The only 2 cons I see so far are that:1) the covering is "frosted" which means you need to keep them clean. The wind won't blow the settled dust off of them, you will need to wipe them down between uses for maximum efficiency. I have no problems with that so it's more of an observation than an actual con.2) The adapter for gz batteries is a little on the loose side but it seems to work well enough that, again, it's more of an observation than a drawback.If you need a small(ish) set of panels these are great!

So far so good. I like the many adapters that it comes with. I also really like the built in USB ports for charging devices. The "foldable" design makes it nice and compact for storing and for transporting. I looked at many others and decided on this one because it was foldable and had the USB ports built in. I am not disappointed.

I used this on a fishing trip in alaska - where we camped and floated down a river for 8 days. This solar panel charged all my stuff - was left out in the rain - got tossed around the boat - and it worked like a champ. Good product - does what it is supposed to do and then some.

I love the size of this panel for the output power it provides it provides. It is perfect for longer stints of camping without power. The quick charge USB port is great. The quick charge doesn't work when really cloudy, but the standard USB port works will on dreary days. This pairs perfectly with my jackery 150 for unlimited power (within reason). Phones, laptop, etc... I keep this in my truck all the time and it stores nicely under the seat. I haven't needed it in an emergency situation, but could use it to trickle charge a car battery if it was run dead.

Works very well with,both my goal zero yeti 150 and 1250. Compact, pretty light, and I'm thankful it came with th 8mm adapter
