Revolt Solar USB Charger Snapback Hat for Cell Phones and USB Devices. Perfect for Your Busy Summer on The go!

I got this hat and its amazing. Its a high ends quality hat hands down. My girlfriend was over sea and used it to charge he cell phone and headphone while enjoying the great out door. the best part was she did not have to by a power converter. Back home in the state, she wear it on her daily walks or hiking at Red Rock Canyon. its a great buy for your money so I bought a second one for me to use Hehe. Now we have a matching hats.

What they don't mention is there is no other way to charge the hat besides the solar panel, so you can't charge unless your outside in the sun, that is, if your hat even works. My hat was directly in the sun for an hour and my phone didn't even register that it was plugged in. Returned it 2 days later.
