I actually really like it,It's a moderate at 15 watts,I didn't realize this was the smaller wattage of the panels,I actually thought the color had something to do with the price.But what's important is,it works really well and better then I expected.It's enough to charge things moderatly fast, in good sun of course, it's Ultra lightweight,and I couldn't believe how small and well made this thing is!It has a special compartment/pocket to hold the phone or battery pack in place with a strap to keep the item from falling out while charging,And keeps the item out of the direct Sun.It's actually a lot fancier looking than I expected as well and the panels seem to be tough!This will be perfect for adventures in the woods!

A lot of people complain about the charge times or it not working. First it's a solar panel, it's not going to charge as fast as it would plugged into your car or wall. Second it works best when it is outside in direct sunlight, not behind glass, not in the shade, not in cloudy weather, IN DIRECT SUNLIGHT. It will charge if it's not in direct sunlight, but much slower. Also it's going to take longer to charge if you're using your phone while charging. The more you plug into it, the longer it will take to charge everything. It also doesn't help if you're using a 12ft long cable. So keep in mind when buying this, direct sunlight, turn off the device you're charging, charge 1 device at a time when possible, and use the shortest cable possible.It's very useful to have. Good for camping, hiking, hunting, survival, emergency preparedness, or just being environmentally conscious. If there's a reason why you can't charge your phone from an outlet, this is perfect. The size is about that of two tablets/iPads stacked on top of each other or a small laptop when folded up. And about 3 or 4 tablets/iPads side by side when opened up. It came with some carabiners so you can attach it to your backpack, tent, a chain link fence or just about anything that would help face it in direct sunlight. It also has a little indicator light where you plug your USB cable into that lets you know if you are getting power, the brighter the light, the more power you're getting.As long as you keep those few things in mind this solar panel is effective and super simple to use.

Bought one of these in 2019 for a sailing trip in the Caribbean on which this solar panel (and it’s twin) we’re heavily used for 3 weeks to charge our various devices. It worked very well (even draw a little power on cloudy days) and kept us free of battery anxiety for weeks. We never had to use the boat’s power to charge our non-essential electronics, which very became important during our voyage.We found the trick was to use the solar panel to charge a power brick, then we’d charge our phone / ipad / cameras / whatever from that brick later (usually overnight). We used the provided carabiners to clip the panels to the awning and then we harvested the sunlight.My only complaint is the pocket in my model (for sale here) closes with a small strip of Velcro. You have to be very confident that your power brick / device is secure enough in the pocket to not fall out (no problem if you’re using the solar panel on the ground, but there was a risk on a boat!).The opening to the pocket is on the bottom, so if you clip the panel to a vertical surface (like your backpack), the thing you are trying to charge will likely fall out of the pocket. I went for a hike with the solar panel unfurled and clipped to my backpack, and had to keep the power brick / phone either in my backpack, or in my pants pocket while it was tethered to the solar panel via charging cable. It was an ok workaround.My friend brought her solar panel on the trip—also Big Blue, exact same size and specs—but her pocket closed with a zipper. Highly recommend that kind of closure if you intend to be actively moving (hiking / biking / sailing) with your solar panel!Overall, given how we needed to conserve power on the boat, this panel was an essential tool on our trip that we relied on every day for weeks, and it delivered!

This worked beautifully from a southwest window in my home. I hung it in the window and it charged my phone and a portable charger quickly (I don't remember how long but I remember being surprised that it wasn't multiple hours, it was fast). 5-stars because I learned that this product works indoors!

I have bought other smaller voltage solar chargers that claim to charge an iPad and smart phones. They charge phones very well, but do not have the ‘pure’ electrical charge needed for an iPad. This one however does. It looks well built and seems to be made with quality.

This works pretty well and charges faster than some of the other solar panel chargers I’ve bought in the past. It even works during cloudy weather.
