This is better made than the other two solar panel brands I own - Big Blue and Solorage.
When charging in high temperatures, cover your device (phone, tablet, power bank, drone battery, whatever) in insulating material like a heavy-duty mailing envelope (cardboard works better than cloth). I've had my devices stop charging at midday with three different solar panel brands - and guess where I live? Florida. At first I suspected the solar panels going bad, and since they're inexpensive enough, I'd buy a different brand. Eventually, though, a notice popped up on my phone - "Charging will continue when the device cools down."
Insulate your device when charging in high temperatures.
Another problem is what I call "backcharge." It's the gradual draining of your device's battery while connected to the solar charger when there's no sunlight. So keep an eye on whether the panels are still in the sunlight or not - which isn't as easy as you might think due to distractions by other things.

Charged my 10,000 mamp battery bank in 3.5 hours in bright sun. Not sure of the durability or how it will work in overcast days. Purchased to use backpacking will see if it works clipped to pack or only at camp.

I love these style of panels! Perfect for backpacking and charging small electronics or power banks. This type of panel construction seems super durable and strong.

10 watt works to get a charge and that's in the winter sun. The water resistant coating on this is great. I'll be putting it away when it's raining or snowing but when random water hits it, I'm confident it will be alright. I figure the only real weak point as far as water resistance would be the inside of usb port. By the way I really could not tell which type of usb this female port was from the pictures, details and reviews. Seems to be different among the models as well. For the 10 watt I got its a USB type A which is like the large usb you might plug into a charger block or into a computer. I'm using a regular charger cable, USB-A to USB-C and that's going into a regular slim 10,000 backup battery. Will be an excellent way to get a little extra charge while bike touring. Glad I bought this.

I rated this product with 5 stars without putting it through any serious testing all though I did connect my cell phone to the solarflex straight out of the box in which my cell phone battery was completely dead and I got 85% in 2 hours with rain clouds over cast and no sunshine. All and all I would say it seems to be well made, and reasonably priced would've been nice to got a padded case, and usb.
