100 Watt Portable Solar Panel for Power Station, Foldable 100W Solar Panel for Camping Hiking Off-Grid Living, Monocrystalline Folding Panel Solar with 5V USB 18V DC Output(Black)

Unit didn’t come with cables to attach to an rv battery

I'm very pleased with these solar panels. They're light and easy to transport, they fold up nicely, they're a cinch to deploy, they come with a bunch of adapters for wide compatibility, they support modern charging protocols, the zippered pocket on the back is very convenient for keeping cables and small charging devices organized, and most importantly, they charge my electronics quickly. I haven't tested their power output, but I think the 100W label is a little misleading. Other sources I've seen online that have tested the power output have achieved around 55W in full sunlight. I think the 100W label represents what the company was able to achieve in a laboratory, possibly with an artificial, super-bright light source. Nevertheless, 24% is excellent efficiency, and 55W is plenty for my purposes: I can use these panels to fast-charge a couple of cellphones at a time, or a battery pack, or even use and charge my laptop. Because the solar panels are so light, you'll want to weigh the folding flaps down with rocks or branches if there are strong winds lest the wind blow the panels over. I bought these for camping and am very happy with them for that purpose. They're portable enough that I even use them as a sun shade in my car so I can charge a power bank while I'm parked.

Buen complemento para la batería

Super efficient solar panel. I love all the interchangeable plugs it comes with. Charges my Jackery in no time at all. It's nice and light but still tuff enough for being at the campsite. We like it so much we got the same one for our son in law. Great double panel for the cost.

I do mobile live streams in the field. First trip out with my Jackery Explorer 240, I had a laptop, camcorder, and cell phone on it. After 7 hours it was at 28% remaining. Good enough, but also bad enough that I knew I needed something to augment the Jackery or be limited in the amount of time I could stream. So I got this panel. Second trip (full sun all day), I had the 240 powering the laptop and camcorder, but also added a laptop cooling pad and an external fan. The solar panel was feeding the 240, as well as an additional cell phone and additional external fan directly connected to it. The 240 remained between 99% and 100% all day. The panel also ran the directly attached devices without issue as well. When the 240 was using input from the panel to charge, it reported 60w input (which is the max it takes from the wall wart as well). In other words, the panel easily fed all the devices attached and did so for the duration of the 7 hour live stream, even as the sun began to wane in the evening. I do not need to charge the 240 before my next trip now as a result; it's already at 99%. The issue I found was with the stands. There are just seemingly fabric-wrapped carboard (or some other flimsy material) legs that are fine, unless there is a hint of wind. 5 minutes after I set up the panel, a 10 MPH gust knocked it down. I had to add some weights to the legs to keep it standing. Other than that, the panel is great and I'm really glad I got it. All I lack for a full review at this point is time. If it holds up, I'll probably add the 5th star despite the poor leg design. That's easy enough to work around, except it adds one more component you'd need for reliable use. But as far as performance goes, it's outstanding for me. *Edit- third and fourth trips out with this, in the same usage scenario as the second trip, only these times there was full, heavy cloud cover the entire time. Even with zero direct sunlight, the panel kept everything running and the power station was kept at full charge throughout the 8 hour day, with the panel still delivering 60w to the power station when needed. Very impressed with the power generation despite not being exposed to direct sunlight. Solid buy, no doubt. **EDIT #2- The panel itself continues to perform very well; however, the USB 3.0 port has broken. The plastic connector inside it has snapped off, rendering it totally useless. So now, I have only the USB-C port available. The seller told me Amazon customer care would send a replacement, but Amazon refused. The seller then sent me a new one directly. Huge props to them.
