Now you can always enjoy a cool breeze on a hot day with the Coleman® Zephyr™ Cup Holder Fan. It fits in any standard Coleman® cup holder, and it also sports a mini bail handle to hang from the inside of your tent or shelter. Once you have it in place, the pivoting head lets you direct the comforting breeze exactly where you want it. And rest assured that when the next heatwave comes, you'll have the power you need, because this fan is protected by the BatteryLock™ system, which stops battery drain. On a normal battery-powered device, there is typically some residual drain as long as the battery is connected in the circuit, even when the device is off. By simply rotating the bottom of the fan, you can completely disengage your batteries, so they can be stored in your fan for years (up to their inherent shelf life). You’ll also reduce the toxic corrosion that can damage your device. So no matter how many days you sit out in the heat, this fan will be ready to make your day a little cooler.
