Buen complemento para la batería

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.

Works great charges the jackery 300 with no problem

I just purchased a second one of these panels I liked the first one so much. You really can’t beat these for the price (with discount when available) and the small/light footprint. The carry handles are great and the accessory/cord bag attached is very handy. The power hub attached to the back of the panels works really well. I like how there’s an LED that appears when you’re getting enough sun for charging. It’s also nice to have the various USB types and multiple ports for multi-device charging. You can easily make your own wired connector to daisy-chain multiple panels together. Positive and negative wires so there’s not much to mess up. One panel in full sun charges my 300w battery hub in about 5 hours. It’s actually faster than plugging it into a wall socket. It takes one panel about 8 hours in full sun to top off my marine battery from half, which is pretty impressive! I’m very impressed by these panels. The build quality is just fine. They’re not going to survive a drop off a 20’ rock, but they can be thrown around, blown over by wind, stormed on, or accidentally stepped on without it being an issue.

It's a really nice unit but I am not sure it can actually output 100 watts. I live in arizona, we have very intense sunlight, and even in the midday sun with the solar panel pointing directly at the sun, the most output I have gotten it to produce is 70 watts. Maybe there is some condition where it can produce more than that but I have not found it yet. Otherwise though it's built well, it's nice that you can plug in USB devices directly into it so you can charge your phone from the panels directly. It also comes with adapters so you can plug it into most power stations. Hopefully it lasts!
