Goal Zero Nomad 10, Foldable Monocrystalline 10 Watt Solar Panel with USB Port, Portable Solar Panel Backpacking, Hiking and Travel. Lightweight Backpack Solar Panel Charger with Adjustable Kickstand

Recently bought and tested the Goal Zero Nomad 10 on a mostly cloudy day using the Goal Zero Flip 20 and am very satisfied with how quickly it charged the device given the less than ideal conditions.For context, I live at 4900 ft above sea-level in a high desert, so the UV even on a cloudy day is very high. The Nomad 10 fully charged my Flip 20 (which was completely dead) in just under 6.5 hours. The first hour of charging was clear and sunny conditions, while the rest of the charging time there were thick to partly cloudy conditions. I checked the charging progress on the Flip 20 (it has 4 LED lights to indicate the power level) every hour and even with the cloudy conditions, it was charging to some extent, but, the best charging occurred not surprisingly during the first hour when there were no clouds overhead. I haven't a chance to test it out on a perfectly clear day yet, but, judging from how quickly it charged the Flip 20 the first hour, my guess it would fully charge in 4 to 5 hours in direct sun.Overall, I'm very satisfied with the Nomad 10 so far. After doing a lot of research on portable, low weight solar options, and having great experiences with other Goal Zero products like the Flip 20, I opted for the Nomad 10 because it strikes a good balance of wattage, size, durability, weatherproofness, and weight and I'll be using it primarily for backpacking, bike packing, car camping, and emergency use.The only improvements I think Goal Zero could make would be to find a way to make it fully waterproof (the USB connection point is the only place where water could wreck a power bank or other device that is being charged) and to reduce the weight even more by using titanium for the bracket that holds the Goal Zero brand power banks as well as the adjustable stand. It would add more cost, but the weight savings, especially for backpacking and bike packing where ounces can really matter would be worth it.

I initially bought this for on the go charging but quickly realized the Nomad 10 is the perfect solution to charge my Ring Stick Up Cam (battery) for outside. The Ring branded solar panel did not register any sun input when installed and on a whim I tested this one. The Nomad started to charge immediately and never allows the cam to drop below 98%

This is a great little camping or emergency solar panel. It is a bit heavier than I wanted it to be, but it's also much more solidly built than I expected. It feels like it could take some pretty good abuse and keep working. I was able to get 8 watts with direct sunlight outside on a clear day in the midwest with the panels pointed directly at the sun. I also use it to charge my phone during the day by hanging the solar panel in front of a window. The window nearly cuts the output in half to about 5 watts, but that's more than enough to fully charge a 5,000mAh battery on a sunny winter day.

Product is good but shipping was extremely slow. Had to contact Amazon several times about shipping and finally shipped 3 weeks after I ordered it

Bought this for my upcoming back country elk hunt. Very light weight and the whole thing feels very durable and not cheaply made! I’ve always liked Goal Zero products. I plugged my iPhone directly into it to test it and it started charging immediately. Cannot wait to use this with my Venture 35.

I bought this as something to keep in my backpack in case I need power on long outings. Did not disappoint. Very light and portable while not being flimsy. It’s obvious that it is very well-made. I gave a four stars on the water resistance because obviously the USB port itself is not water resistant. Also, the charging power technically is only 7.5 W as that is the limit that the USB port can output. Overall, a great solar panel that will last me for years.

I have seen lighter devices on trail. I was charging my phone... my wife's phone.. her GPS watch and my garmin for 23 days. Great power supply.

The Goal Zero Nomad 10 works as expected. I used it on a week long ocean sailing trip. I charged a portable 10000mAh USB battery (ANKER PowerCore 10000) during the day with the panel and used the battery to charge my cellphone and go-pro each night. I had direct sunlight but the panel got sprayed by the occasional breaking wave - though never too soaked. The device worked really well and I would recommend it to anyone for value for the money. The only con was that the device does not include any carabiners or fastening clips.
