AC Infinity Turbo Fan Power Adapter, for MULTIFAN Series USB Fans

Paired with blower fan. Works as intended. Good value.

These fans are of impeccable quality! The fit and finish and even the packaging are far above their price point. I would have easily paid double for what I received. I also bought the AC Adapter which gives it 25% more power. The fans are indeed super quiet and you do not hear them at all over the music/ audio at all. I am using them to cool my beautiful customized ReVox PR99 MKI Reel to Reel Tape Deck. Two fans sitting on top pulling the hot air out of the machine resting on the little rubber pads so nothing is vibrating with metal on metal. The On/Off 3-speed (Low, Medium & High) selector switch is inline with the power cable and dangles right behind the deck for easy access. You don't really even see the fans when tape is mounted and playing and even if you do see them it is okay because they are "cool" looking! Pun intended! Amazing quality for the price folks! They are working great in keeping the machine cool. I will be purchasing some more of them for my Tube Integrated Amplifier which uses eight KT-150 Power Tubes to keep it cool as well. Highly Recommended!

I have Ac infinity all over my house, in my tv cabinet, under the game consoles, under my laptops, and routers, you name it and its always a good solution.But with this adapter that makes it so much better, instead of adding more fans, or being limited by the 5w generated by the USB port, i've seen the performance almost DOUBLE with this adapter for marginal noise level bump in the fans, i was shocked to see how much of a difference this actually makes.ADDITIONAL BONUS: this adapter will have warning and restrictions and rating s all over it, and mentions not to be used without its intended purposes, however i have a laptop cooling fan where the usb/fan specifications were compliant with this booster, and the laptop cooler FINALLY lived up to its hype of cooling my laptop down, it was like purchasing a brand new product, so i purchased 3 more of these for other projects!!!would recommend-Mr.J

I always felt like my AC Infinity fans were just a little weak sauce. I used the 140mm X2 for years just on simple 5v adapters. I used this turbo adapter and wow! While they are not instantly 100% better, its noticable. Not too much louder either. Before, they were silent so anything above that was noticable. Now I'm curious just how much more voltage these fans could take. Could someone apply 12v and not instantly burn out the motors? Meh... Consider this adapter a essential purchase if you want airflow and don't mind a little more noise.As everyone else has said, don't leave this adapter sitting around, it's kinda dangerous and will trick anyone looking for a USB charger. Label, label, label: Not a USB charger.

I did check the voltage output with a USB meter (Drok) and it is higher than a normal USB power brick so as they warn you quite clearly, be careful what you plug into this, you may fry other products.It is currently running 4 fans, they are doing a good job, I did notice a slight increase in fan speed using this compared to a regular USB power brick, so there is validity to the claim that this will improve the output of an AC Infinity fan, I just cannot measure the absolute wind velocity or cfm to show how much of an improvement. No big deal to me, they are all working exactly as designed & that is all I need.I gave 4 stars only because it is hard to really tell how much of an improvement I get. But this is a ROCK SOLID 4 stars as the produce is well made, the company is excellent with Customer Support and I am very happy with everything I have from them.I get no compensation for my reviews, I just like to offer real world experience after I have used the product for a while & not just after I open the box.

I bought this to drive three AC Infinity USB fans that I have placed in a large media closet. I was worried that these three fans - which I leave in 24-7 to cool - some expensive equipment - might otherwise pull too much current. So, I really bought this little doodad to insure the fans were adequately powered. I liked the safety rating too. I am paranoid about fire hazards and a possible blaze breaking out when we are not home.... especially since I just spent 13 years scrimping to pay off the friction' mortgage! Cheap insurance! Well constructed! Now I am back two years later to buy another set of fans to protect my WFH workstation and home office gear....

It works but I really can’t say it gives the fans much more speed than my regular usb chargers . I did plug my ac infinity fans into a 12 volt system and they really gained some speed and operated great. However I was afraid to leave them on the volt for fear it might damage them. But one things for sure these fans could take a little more juice to make them more effective .

I got it for my fans and it works good with it.
