Goal Zero Nomad 20, Foldable Monocrystalline 20 Watt Solar Panel with 8mm + USB Port, Portable Solar Panel Charger. Lightweight 18-22V 20W Solar Panel Charger with Adjustable Kickstand

This is a great portable solar panel. It folds down to 7 by 11 inches which makes it easy to carry in a backpack and it does to weigh more than a few pounds. It has an 8 mm so it can be attached to a larger panel if needed.

I plugged this used panel in and it works great. A little scratch on it, as advertised, but it works. That's all that matters. Thanks!

Still in the testing phase. In the winter sun I got about 30 percent increase in my phone before it stopped charging. Went on vacation was very happy with it. Charged my iPhone and my speakers EXTREMELY fast but again it only gave my phone about 60 percent battery in about two hours. Sun was still high in the sky in Bahamas sun but stopped charging slight/minimally no overcast. No sure if the device over heats and stops charging or if the VERY little bit of clouds cause it to stop charging. Still pretty happy with it because I’ve bought the big name brand Dark Energy for about 100 dollars more than this and it was useless

This is a very nice high quality solar panel. It’s only 20 watts, but, you can tell it’s going to last a long time. Happy I bought it.

Such a great product and reasonably inexpensive. I have used it outside to charge a cell phone. I haven’t used it yet to charge my yeti but with as much as I’m outdoors I know that I will. If you spend a lot of time outdoors and need to keep your devices charges, I recommend this device.

I had high hopes for the Goal Zero Nomad 20, but unfortunately, it didn’t meet my expectations. While it technically worked, the performance left a lot to be desired.• Slow Charging: The biggest issue was the incredibly slow charging speed. Even in full sunlight, it took far longer than expected to charge devices, making it impractical for use in situations where reliable power is essential.• Decent Portability: On the positive side, the foldable and lightweight design makes it easy to carry and pack, which is convenient for outdoor activities. However, this benefit is overshadowed by the poor charging performance.• Build Quality: The panel itself seems well-made, and the adjustable kickstand is a nice feature for angling it towards the sun. Unfortunately, these features don’t make up for its lack of efficiency.Overall, while the Goal Zero Nomad 20 has some good design elements, its underwhelming charging performance makes it hard to recommend. There are better options available that provide faster and more reliable power.

This solar panel works great. It charges our battery packs fairly quickly and stays standing even in some wind. I have no complaints.

Works as advertised, great power source to recharge handheld devices and power banks.
