Ryno-Tuff 21W

I bought two panels to test for a Wyoming hiking trip I went on to, the Ryno was one of them. Since we would be off the grid for almost a week, and I planned on doing some amateur radio activities, I had to be sure it worked. The product is ok enough and I ended up keeping it and using it, but they ...

I've tried a number of charging solar panels. Many are flimsy, or trickle power so slowly that it's pointless. This one is the real deal. Very sturdy (which means it is a bit heavier, but that's OK). Great carrying case to keep things protected. And boy does it power well. I set it outside with an i...

I used the Ryno Tuff charger for six days of Boy Scout Summer Camp as an adult leader and it proved indispensable!!! I used a 10,000 mah power bank to charge my phone each night and ran a 4" USB fan off of a 4,000 mah power bank through the night to stay cool. Each morning the 4,000 pack would be fu...

The Ryno Tuff charger performed excellently on a week-long backpacking trip in the Sierra Nevada in late July/early August. We could charge two phones at once whenever the sun was shining, even when it had just risen or was about to set. Phones charged fast during most of the day. It could charge a ...

... because it's a SOLAR charger! Sorry, I read about a thousand reviews where people were upset that these didn't work properly when it's cloudy. (eye roll) That is correct, it works perfectly in full sun. Yes, it has to be full sun, because, again, it's a solar charger. My husband and I camp and w...

I received the charger on a day it was raining. It doesn't happen very often in Phoenix, but it does happen. Anxious to try it out I placed the charger in my living room window. Instantly the charging indicator light came on. I plugged in my android phone and it began charging! This was through a pa...

I carried the Ryno Tuff charger on a 5 day trek through the San Juan Mountains. It was easily attached to my backpack, and usually it worked best near the top of my pack. I set it out at first light (it really does need direct light) and had to move it around to keep up with the changing angle of th...

There is NOTHING not to like like about this solar charger. Light, portable, and charges my LG phone sooooo fast on the fast charger. I use the dual USBs to charge one cell phone and my Anker powerbar. Charge time on phone using the fast USB port is basically 1% per minute in full sun....maybe a lit...

I purchased this to take with me to Africa. The cost was the same as having to purchase a converter and adapter. I'll be out in the bush where I can just lay this out during the day to charge primarily my camera batteries. I'll also take it on a portion of the AT next summer. It does add almost a po...

I just received this solar charger and have only used it once so far. I wanted to see how it would do in charging my portable battery I use for camping and hiking. This charger worked great, it was unbelievably simple to hook up my battery to charge. You just plug the USB side of the cord into the s...
