Bests & Worsts Reviews from Amazon

I have purchased many battery operated fans. This is far and away the BEST product in the bunch. I live in an entirely 12 volt, solar bus conversion. I need these fans to circulate heat down from the ceiling and away from my heating source. They clip on and stay put. I clip them into the bus hatch and they serve as a ceiling fan. Also, they rotate fully in every imaginable position. No "rotating" fan I've bought does this. They come with a rechargeable lithium ion battery! So no more purchasing triple A's or cycling through rechargeables that generally have to be recharged with 110. Now, you can easily recharge these with standard 110 just like you do your phone but I only have 12 volt. Get THIS, the fan has speed control! Turn the dial on and the more you turn it up, the higher the speed. On the lowest setting, the fans will run for approximately 10 to 12 hours on a charge. So for me, they will run through the night keeping the warm air circulating while I sleep. In the morning, I recharge them. One drawback, the little red LED that says its charging doesn't turn green for instance to let you know it is charged so you have to guess. I charged them for 5 or 6 hours and they were ready to go again. There was no visible drop on my solar battery voltage after charging them. 13.7 volts at start and finish so they must not use much power to charge (I have 3 of them). I'm buying 3 more so I can have a set running and a set charging. I'm so flipping happy.
