- Not what I had hoped.- April 24, 2021
This item was not what I expected and has been returned. I was under the impression that it stored solar power. For example, that I let it sit in full sun, then later in the evening, I could charge my device. In reality, my device needed to be connected while in the sun, but I actually lost battery power while this was connected. I tried it for several days and in full sun. Also, the price had dropped $20 since I had first looked at the item, so I thought I was getting a deal, but it appeared to have been a used item. The packaging was nice and tight, but the area where I plugged the usb to charge my device was scratched a good bit and definitely looked used. I didn't want to purchase an open box item.No, I would not recommend this to a friend.
- This Solar Panel is Awesome!- August 15, 2020
I live ‘off the grid’ and this little panel charges my Bluetooth, speaker, my cell phone, my ipod, my rechargeable fan, my Skull Candy headphones, and all my other devices.? It is surprisingly powerful and you can fold this puppy up and backpack with it. No matter where you are, power for your devices is always available during the day........and it’s FREE!!! Leave only footprints, and no carbon behind!!!! I LOVE this little ‘green companion!’ I often think of the simplicity of solar. And while our long ago ancestors used it to their advantage, today we can utilize it to help save our planet. I live on 2-100 watt solar panels, and this Renogy 21 Watt tri-fold is the perfect compliment to my ‘green life!’Yes, I would recommend this to a friend.
- Huge! Made for the boonies, not the city.- October 15, 2020
If you are going somewhere that doesn’t have electricity, has adequate sunlight and you’ll have enough time & space to unfold this & let it charge, this product could be a life saver by allowing you to charge your cell phone & call for help. Or a boredom saver by allowing your kids to charge their tablets. I bought this to use when I’m too hurried to wait on my phone to charge fully. That wasn’t a good use for it. I returned this because it was so big. It took up 1/2 of my dashboard when it was unfolded. It needs to be unfolded to get the sun’s rays. It wasn’t practical for me to leave it unfolded for hours so it could charge. I couldn’t drive with it sliding all over my dashboard. It stays overcast in our city a lot so sitting it on the seat in my car wasn’t giving it enough sunlight.Yes, I would recommend this to a friend.
