[Upgraded] BigBlue 3 USB Ports 28W Solar Charger(5V/4.8A Max), Portable Foldable Solar Panel for Camping, IP44 Waterproof, Compatible with iPhone 11/XS/XS Max/XR/X/8/7, iPad, Samsung Galaxy LG etc.

When I first purchased this portable solar panel, I was skeptical about its capabilities. To be honest, I didn’t anticipate its impressive performance. Let’s begin with the build quality. The manufacturer has done an excellent job with the design and construction. The foldable design makes it incredibly portable, and the panels themselves feel sturdy and well-made, not cheap at all. I appreciate that it comes with carabiners, which makes attaching it to a backpack or hanging it easy and convenient.Since I’m always on the go and carry a lot of tech, I’m constantly in need of extra power for my gadgets. I paired this solar panel with a NESTOUT 15000N portable outdoor battery, and they work seamlessly together for my needs. The solar panels keep my battery charged, and I use the power from the battery to quickly charge my devices. The USB-C ports and USB-A port works great without any problems and allows me to connect to my devices quickly without any delay.Now, don’t expect these small panels to charge devices rapidly. They do the job, and so far, with the sunlight I’ve been exposed to daily, they’ve worked flawlessly. I highly recommend this product. Considering its limitations and my use case, I believe it was a wise investment. I’ve also recommended it to several friends who work outdoors, and they’re equally impressed with its performance.

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!

Used on a long hiking trip. Was able to fast charge in full sun and charge my phone in a few hours. Product is light and packs easy, survived lots of abuse. They put the pocket on upside down in my opinion though.

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.

I received my solar panel last night and i’m currently putting it to the test. @ exactly 9:49am, i hooked up my completely dead OnePlus 7 Pro (4,000mAh) (that i don’t use anymore) to the solar panel. As of 10:30am the phone battery is at 16% which btw is really, really good given the lack of direct sunlight due to the cloud covers skies. To give you a better idea of how cloudy it is, i can look directly(or indirectly?😅) at the sun without going blind; Well, kind of. Also, I think if i were to charge my iPhone, it would be at ~20% charge since it has a slightly smaller battery (~3687 mAh). I bought this solar panel for the purpose of using it at a camping festival i’m going to in 2 weeks. Needless to say, this will suffice! I’ll update this review as i test it over the next few weeks @ different times of day.Edit: Friday December 22, 2023 2311I took this solar panel to Lost Lands (camping music festival) and it came in so clutch! I brought 3 power banks just in case (10k mah, 20k mah, and 30k mah), but with the solar panel, I only had to use the 10k mah powerbank. I would use the 10k mah throughout the day/night (7am-3am) and then I would set up my solar panel on my tent and hook the power bank up. That way, by the time the sun came up, it would be charging and be ready to be used by noon. The festival was from Tuesday-Sunday. The solar panel was charging very efficiently and very quickly (in my opinion). On nights when I didn’t set up my solar panel before going to sleep, I would wake up early in the morning to set my solar panel up and hook my powerbank to it, then I’d head down to the showers and by the time I got back it was fully charged. (Shower lines were long so I’d be gone for roughly 1hr-2hrs). Also, there would be times when it’d get a little cloudy but, the solar panel still charged pretty well. Though, not as fast. Overall, super useful solar panel. Totally worth it for the price.
