20W Small Solar Panel Charger 5V USB-A USB-C Foldable Portable Lightweight ETFE Power Emergency Panel IP67 Waterproof Hiking Camping Backpacking for Phones Tablets Power Bank

I took this on a 7 day back-country hike at Philmont Scout ranch in New Mexico. I was often out of cell range, so had my iPhone 13 Pro Max on airplane mode most of the time. Hanging this from my backpack, it consistently charged my phone from ~70% to 100% in 2 to 3 hours hiking in and out of shade and partial clouds each day. In bright sun, it charged my “brick” backup lithium battery from 40% to 100% in 4-5 hours of bright sunlight. In a reasonably sunny climate, my experience is that this panel could keep personal electronic devices for 1 person charged indefinitely while on a trek. Thumbs up!

Charging an iPhone Pro went well, but not a Macbook Pro hahah. The charge in was not faster than the charge used on my laptop. But I tested this from inside, so it might do better outside. I like that the ports are on the edge so you don't have to worry about wires bending and breaking with time.

Not sure because of the fact it is foldable, its not super powerful to charge phone. I left for hours in sun light. It's just 20% charged. Can be used for little things. If you are looking for latest phone to charge need better one.

Works better than their e40 foldable panel but I would get another brand

Great little solar panel for my sailboat. Chargers Bluetooth speakers and Apple devices when we are underway.

It charges my iphone as soon i flip it open. Even under a shaded area. Its super light and durable.

This thing charges super fast and was great for the first 4 days of my 9 day trek in Peru. But then it stopped working unless the panels were angled at about a 30 degree angle, and the charge speed was super slow after that! I think there was an issue in the cabling in the hinge. Either I got a defective unit, or this thing just isn’t durable enough for more than a couple days of usage.

Allows backflow of electricity, when plugged in at night, it uses electricity from your destination. Tested on bench.

I took the FlexSolar 20W Solar Panel Charger on a recent camping trip, and I’m really impressed with its performance! It’s compact, lightweight, and folds up nicely to fit in my backpack, so it doesn't take up much space. The build quality feels solid, and I love that it’s IP67 waterproof—definitely came in handy when it rained briefly! Charging my phone, power bank, and even a small fan was easy with the USB-A and USB-C outputs, which is super convenient. It charged my devices at a good pace, even on cloudy days, though of course, direct sunlight works best. I like how I can set it up anywhere—on the ground or hanging it off my backpack while hiking—and it just works.

Great product. charges devices fairly quickly but does need to be in direct sunlight to get the best value and fastest charging. It is strong enough to stand up to regular use in the backcountry.

You can tell once you pull this out of the packaging that the build quality is very solid. The panels are solid and protected from the elements. Ad long as the ports remain connected inside the unit it should last for years. I wish the USB c output could push the full 20 watts and not just 15. But that's really my only criticism. Great to have when camping to keep all your power banks charged. Between the kids, my wife and myself we all have batteries that need charging. This thing seems to keep up charging all of us. A 10,000mah battery pack charges to full in under 4 hours. Recommended!

Good luck to charge your phone with this scrap

Takes a very long time to half charge a phone. Must be in direct sunlight to charge. Not very satisfied.
