[Super Thin] Portable Solar Phone Charger, BigBlue 15W Folding Solar Panel with Dual USB(5V/3A Overall), IPX4 Waterproof, Compatible with iPhone 11/Xs/XS Max/XR/X/8, iPad, Samsung Galaxy LG etc.

Product is well built, look and feel very professional. Managed to charge 2, 10,000 mAh power bank at 75% fully in direct sunlight 25% and over cast sky 75% of the time in 4 hours.Had placed order for another 2 pieces of 28W panel from the same brand.

I'm a homeless person, so you know that when I use a product, I use it under extremely demanding circumstances. The product is small and easy to carry around, getting quite nicely in the hand. If I needed to stash it in my backpack and run, that would be very possible. The crystalline panels and feel durable enough, I tossed around the panels on the ground a bit trying to get the right angle, and they held up quite well, however I did have some difficulty as the panels would flop around so much. I was able to use the panels 70% other day and got an equivalent full charge on my phone.However, the panels got bent. You can imagine my disappointment as when I tried to pick up the panels and place them into their tactically folded position, they wouldn't close. To my horror, the top piece was also very warped. As a homeless person, something that can't collapse is basically worthless. I'm going to try tomorrow to bake it in the sun, and try to fold it while warm.To be fair, I let it bake in the California sun for 8+ hours a top of dry weeds, but to my credit the product's purpose is to sit in the sun, so yeah.edit: it just needed to be worn in, I was gonna 2/10 return this thing but if I cojole it and tied it up with string it folds perfectly! Still a great product to have in my homeless set.Edit: I have been using this product for two months now, and it has withstood some horrifying circumstances. Including, being stepped on being overheated being folded wrong. Being able to charge my phone but the sun has been such an asset. I cannot overstate how important this is. However I can only charge one phone at time. This is standard solar panel marketing, I just wish I knew this ahead of time.

After 1 month of use:Keep in mind this solar charger output is 2.1A (x2) it works as advertised just don't expect it to be a fast charger that can keep up with your home charging adapters. I recommend using a power bank you can top off instead of trying to charge your phone or other devices directly.All in all it's a adequate option for Light duty charging, the unit feels rugged but has started coming apart at the seams. I would probably recommend investing in another panel, for less money you can get a solar option that is just as capable and you won't be as disappointed if your panels start separating from the body of the case.Pros: relatively lightweight, compact, great as a emergency power source for vehicle, home, or camping.Cons: charging can be slow if you have phones or devices with large battery capacity, or if you're used to using fast chargers at home.Might just be mine but a few places where the fabric meets the panels are starting to lift up and come unglued, which is highly disappointing due to this panel being more expensive than other 15w solar chargers.

This thing is great and very fast for solar charging. In order for this thing to work, you have to put the panel in full sun(and I mean FULL sun). The. Don’t move it. Plug in the charge cord and plug device in. Works great if you follow my steps. If you move the panel out of FULL sun, then put it back in the sun, you’ll have to go through the steps again.

Total POS. Don’t waste your money! Cool design but barely charge phone in absolute full direct sunlight. Even moving slightly from direct sunlight stopped charging. I own 4 portable chargers similar to this all work great. I sent this back.
