New DUAL helmet fan kits, powered by 4 AA batteries in a switch box. $37 each shipped CONUS, all PayPal fees included. These are, in my opinion, the best balance between airflow and battery life. I tested these at 3.5 hours of continuous use before the batteries died. This is shorter than some out there, but these provide better airflow than the others I have tried! Most troops are much shorter, so you are maximizing airflow rather than trying to get more life out of the batteries, keeping you cooler during troops! Back in early 2014, I set out to make something that would fit in my helmet better than what I had tried before and through those months of trial and error, working in collaboration with members of my local garrison, came up with this combination. These are high-quality, high-output, small form-factor fans that are hand-soldered and heat-shrunk at the junctions. I use copper wiring and personally test each fan prior to sending it out; this is my name on the product and I take that very seriously. I fully understand that trust is something earned, and I hope I have the opportunity to earn yours. I buy top-quality components in bulk from overseas to pass the savings on to you. It is important to me that each costumer can afford cooling in their buckets to help them troop longer and have more fun doing it![/size] These fans draw from one side, so they are easy to install in your helmet, either by velcro or elastic and can draw air in from the outside to keep you cooler!

Featuring my same slim fan with a quick disconnect connector...easily hide the box elsewhere, run the cable up into the mask and connect! These are the same price as my dual-fan kit...$37 shipped US! I'm pleased to announce the 2.0 version of my rechargeable helmet fan solution: The DOUBLE TAP! In the winter of 2014, I did some work to come up with a solution that could combine my small form factor fans with a rechargeable power supply. After a LOT of trial and error over that year, I'm happy to say that I finally have a solution that I can share with everyone! Several challenges came to the forefront as I used the initial design in my own personal bucket: Would the batteries last long enough? What if I forgot to charge the batteries before a troop? How do I keep the cost affordable? The Double Tap comes with 2 of my small blower fans, connected to a quick disconnect locking connector like I use for the Tusken Cooler. I also include 1 matching, high-quality USB connector and my standard 4 x AA switch box. Have a full battery? Save money and use the USB! Forget to charge it? Switch to AA power within seconds!! I keep the disconnect close to the power supply for quick changes without having to remove your fans! My standard configuration comes with everything seen above: 1 x Dual Fan Kit 1 x USB Connection 1 x Quad AA Battery Switch Box All yours for $57 Shipped US/PR! $79 Shipped Canada! $88 Shipped most other International locations (PM with address for accurate quote) Need a battery?
