I got this portable solar panel to take with me on family camping trips. Its small enough to be convenient and can charge my smaller devices like phones, flashlights, and Bluetooth speakers. Its not powerful enough to power a laptop. There are ways around this issue if you really need to power up a laptop. You can slowly charge a battery bank using this and then use the battery back to power your laptop.The quality of the panels is actually pretty nice. They are sturdy and feel solid. The backing fabric is also really nice. I would not suggest deploying this in bad weather. The charging port is located within a zipper pouch so its kind of protected, however its not designed for getting that wet. I’m sure it would survive getting wet accidentally once or twice, but its really designed to get soaked. This kit comes with multiple adapters so that you can connect it to multiple devices.I couldn’t get it anywhere near the rated power output. On a sunny day in southern Mississippi I could only get a maximum of 23w (and that was holding the panel at a 90degree angle to the sun.I like how you can plug devices to the USB port for easy charging.

This is a very nifty solar panel that's easy to take with you when traveling. When folded up, it's very easy to carry around with its built-in handle, almost like a small laptop bag. It's the smallest panel I've seen yet - about the size of an 8/12" x 11" sheet of paper - that can output up to 40 watts when unfolded, and I can imaging bringing it on trips with very little effort. When folded, it's held together with two straps that snap together with plastic clips, and it feels secure and nicely stowed.I've not measured the actual wattage it puts out to confirm the manufacturer's 40 watt max specification , but I can confirm that it charged up my iPhone quickly enough. Getting it to work couldn't be simpler: you unzip the case, unfold all four panels and expose them to direct sunlight. You need to unzip the attached pouch to get access to the connection port box, which has a blue LED on it that lights up when voltage is available. Once you connect your phone or tablet to the USB A or USB C port, you're good to go.It's not been cloudy where I live for many days, so I've not been able to test the panel in that kind of weather, but even if power is reduced by 50% it should still be enough to charge most portable devices without any problem.A couple of cables are included: a USB C to C cable and a "5521" DC cable (a black cable with coaxial connectors) with a variety of adapters that can be used on it to recharge devices such as a power station or power tool. The rather skimpy two-page instruction "manual" indicates that you should confirm that any device you connect to the panel is compatible with its output levels, which I'm not sure most people would know how to verify. I assume the panel's conversion box adjusts the output voltage and amperage depending on what's connected, but this isn't specified in the manual. The USB A and C ports, however, should be compliant with standard USB specifications, although there is no mention of power delivery (PD) compliance in the manual despite the 40 watt max output level. As I noted above, it successfully charged my iPhone 12, so I expect most USB-chargeable devices should work fine. Note that an iPhone lightning cable is not included, so you'll need to provide one.The charging ports are somewhat awkwardly placed in an attached pouch behind one of the end panels, so if you have all four panels lying flat on a surface, the small, attached box containing the ports is hidden under one of them. It's not a big deal, and I suppose this protects the connection box from direct sunlight. Still, the box is mounted in an attached zipper-pouch that also contains the included cables and adapters, so if you're not careful all of these parts can fall out when you open it. It would be nice if there was an internal storage pouch or mounting straps for the cables and adapters to prevent this.The panel is water resistant, but the conversion/connector box is not, so this unit should not be left out in the rain. The panel can be hung from any two of four metal rings in each of the four corners using the two carabiner clips included for this purpose, so you can hang the panel on a horizontal rope (for example) to get better sun exposure.All in all, I really like this solar charger. Its small size makes it much easier to travel with than others I've seen (and two others I own). It's relatively lightweight, so packing it in a bag should be easy. Its power output is high for such a small panel, so with proper sunlight exposure, it should charge up most devices as quickly as most any plugged-in wall charger.

Living in Florida where hurricanes are becoming more and more frequent, I thought this might make a useful addition to our emergency kit. Although after taking it for a few test drives, I realized that it's far too useful to keep locked away in a closet for emergencies! Honestly, when I ordered it, I didn't except very much from it – most other solar chargers I've used in recent years have kind of fallen short (mainly due to limited charging capacity, slow charging, lack of portability, etc.), so I just assumed that this one would be the same, but I was really pleasantly surprised to find that this one is not only much better than the others I've tried, it completely blows them out of the water!First of all, the design is extremely thoughtful, with features and functionalities that maximize practicality, utility, convenience, and portability. For one, I was shocked to see that it folds up to about the size of a tablet, so it'll fit easily into a backpack or briefcase, assuming you don't want to use the built-in handles to carry it. It's also not very heavy, which is a nice change from some of the solar charging products I've charged in the past. I'd guesstimate that it weighs about 2 lbs. in total, so very easy to tote around without it weighing you down. I'd originally intended to keep it in our emergency kit, but it's so convenient and portable, I've been using it to power a small fan when I lie out in the hammock in the backyard and to charge my phone when at the beach. I haven't tried it yet, but with the included carabiners, I imagine one could attached it to a backpack to power/charge a device while cycling or hiking as well.Secondly, it's surprisingly simple to use! While I've tried a few other solar chargers in the past, a few of them felt as though I needed a PhD in electrical engineering to figure them out. By contrast, this unit is fairly intuitive to figure out, even if the manual were not as clear as it is. The product documentation is clear, concise, and easy to interpret without being overly detailed or cumbersome to digest. I had mine out and in use within 3 minutes of unboxing it. Just unfold the panels, place them in the sun, open the pocket on the side of the panel to access the attached charging cable and adapters, connect your device to the appropriate cable, and voila! NOTE: If you need to charge an Apple product that has a lightning cable, you'll need to bring one of your own, because that is not one of the included adapters.Thirdly, in terms of charging, this baby packs a much bigger, better punch than I've grown accustomed to with the other solar chargers I've tried! As mentioned earlier, I'm not an electrical engineer, nor am I techy, so I can't really speak to technical specifications, but I was surprised at how quickly it charged my iPhone 12 Pro Max when connected. Even in slightly cloudy conditions it worked well – there was a noticeable decline in the speed of charging, but the fact that it still provided a steady stream of power was surprising.I also like that there are safety mechanisms built-in to prevent damage to the panels or the device you're charging. This makes me a little less paranoid as a layperson accidentally doing something to damage my devices.The one drawback of this unit as compared to a few others I've tried is the lack of a battery – but to be fair, that's also NOT what this unit is designed for. This is meant to generate power, not store it. That said, I imagine this could be used to recharge not just mobile electronic devices, but also other portable power banks, which is the reason I ordered this unit in the first place.All in all, I've been extremely happy with this unit! In fact, it has proven far more useful and convenient that I'd imagined when I ordered it, so I keep it by the front door so I can grab it whenever I head to the beach, go out on a hike, or trek to the park. If you need fast, reliable, portable power, I highly recommend this one!

This is small but portable solar charger for small electronics. I like to use this to charge usb battery packs while camping or skiiing or any outdoor activity and then just grab/swap the battery pack out to continue on your adventures.

It's a thought system; too bad it does not produce enough current (amperage) under full sunlight. I would charge my iPhone to 78% and not charge my iPad Mini 5. I tried to charge a basic 10,000 Ma power bank, and it took 8.5 hours to get it to a 3/4 charge.
