I just realized I got in on the Taotronics fan deal a few years ago. I must have been added to their sales list when they pinged me on their current offers. The fan was probably one of the best purchases Ive made from this forum yet. I suspect it was a pricing error. Its been through at least 50 charge cycles and still performs as new. I plan to swap 18650’s when the stock cells fail, but they have done well so far. Too bad their fan appears to be out of production. It blows far more air, and at a higher velocity than any battery powered fan its size that Ive seen yet… including a pricey Dewalt version.
