Review: A BRILLIANT PORTABLE BATTERY POWERED FAN THAT REALLY WORKS - Wow... this is a must for me because I need to cool my large old body always! Of course this very versatile fan isn’t an air conditioner nor ‘swamp cooler’ that provides cooled and moisture added air flow. But this is what this fan is: a great portable design with a large diameter for air flow; both wired and battery power options; super quiet constant operation and truly awesome. Years ago I started thinking and then rhetorically asking why there weren’t fans like this available or even existing in this consumer friendly design versus high end expensive rechargeable fans used for many industries. I may have bought the first version of this fan and for sure wrote the first review on desertcart of it. Now several years later I am writing this review with a well improved version of this fan. The true unique and most important selling feature is the ability to use D batteries to power this lightweight yet nice diameter for air flow design. It also is able to fold into a even better smaller size that makes traveling and camping + any place... able to be added to, or by itself provide the so often needed flow of air directly with you. When used with the plug in power cord attached; this fan will provide a constant breeze like air flow that may not make super hot days into something cool or breezy! But it’s the fan and it’s great functions for the other times when it’s not the only device for cooling down that allows this portable fan to be truly appreciated. In the sum; this is the current version of a genius (thank you!) design that is even more brilliant and more powerful than the first!!
Review: Update after using for four years - Original post: We used this on a three-night camp trip into southern Iowa in August. It made all the difference for getting a good night's sleep. It created enough of a breeze on the low setting to give relief without blowing too hard. On the low setting there wasn't quite enough white noise to cover campground sounds or animals treading about but the high setting did a good job of covering noise. The batteries gave enough weight in the base for it to remain upright all night. We like that it folds up to a very portable size and doesn't take up much room among the camp gear. Update one year and three months after purchase: We returned the original purchase as it was defective and got a replacement without any issues. Very reliable fan. Ended up using it in the bedroom for white noise on the low setting. Folded up, it propped easily into the window. The high setting brought in enough evening air to cool the room for night sleeping and the low setting is perfect white noise. It has run for eight hours a night for 15 months. Other fans we've had tended to develop vibration noises after several months, very annoying and not conducive to falling asleep. Not this one. It sounds and performs the same as the day it came out of the box. The only caveat I have to add is that the covering on the cord separated near the fan body's plug-in point, exposing the little wires within AC adapter cord. It came as a result of the cord bending downward at the connector every night to plug into an outlet below the window. It's beyond repair and needs replacement. We tried a couple of power adapter cords from several electronic devices we have but none worked. I see that a replacement AC adapter cord is available from the manufacturer for $12, about half the price of the unit itself. Based on the performance of the fan, we figure it's worth it. The old cord will go to electronic recyclers. As a precaution, so the same thing doesn't happen again on the new cord, we'll probably wrap some electrician's tape around the first couple of inches at the connection to support and ease the bend in the cord. Overall, it's been a good little fan and worth the purchase. UPDATE FOUR YEARS AFTER PURCHASE: still going! Still using it every single night for white noise. Sometimes it makes a little squealing noise for a couple of seconds but giving it a quick smack makes it stop.

## Questions & Answers

**Q: battery life**
A: After Hurricane Laura I used this for 6 nights and a good bit during day on the batteries that were already in before hurricane.    Replaced batteries on 8th day as the fan was slowing down.  Duracell coppertop batteries.   This is a great fan for the hurricane /emergency box.

**Q: how do you get it open to insert the batteries no directions**
A: Open the fan. On the flat part the holds the fan upright there are 2 plastic screw like things. This piece is shaped like a U. Turn each with a screw driver to remove. Then pop off the top cover. The batteries are inserted inside. Replace the cover and plastic screw like pieces and tighten them.

**Q: Is there a DC car adapter for this fan**
A: Got mine today, 2/11/2022. It came with an ac adapter.

**Q: How loud is it?**
A: It is quite. I wouldn't be able to sleep with a loud fan. I used it in a cruise cabin with no problem.

### ⭐⭐⭐⭐ Operates well on A/C power, but operation on batteries was "delayed"
*by C***L on September 2, 2021*

The size and light weight design of this fan is great. I purchased this fan to use in my little camper when boondocking, as it is advertised to run on six D cell batteries. It worked great on A/c power with the adapter plugged in, it was wisper quiet and moved air in two different speeds. But when I installed the six D cell batteries, taking care to properly install them in the correct orientation, then to replace the cover and lock it into place, the fan would not work. My husband removed all the batteries, replaced them in correct orientation, and then locked down the cover, the fan still didn't work. We unlocked the cover, got a flashlight and checked to ensure the batteries were all making direct contact, that the lead battery was directly contacting the metal plate, and verified that both wires were also making contact with the appropriate plates. But unfortunately the fan still would not work. Too bad, as I really like this design and feel that it would have been great in our camper when we aren't connected to A/C power. However, the next morning we woke up to find the fan running! We were able to switch it off and on, low speed and high speed with no issues. We're not sure why it would not run the night before, and have no idea why it started running overnight, but it seems to be working perfectly now. We will keep an eye on the operation of this fan, in case we have any additional issues. We would like to know why it would not operate the night before. That is still concerning.
