TITANRv Refrigerator Fan Rv Fridge Fan Rv Vent Fan Rv Fan Boost The Efficient of Fridge Vent & Exhaust Mini Design Ultra High Voulm Air Flow with On/Off Switch Smart Battery Power Operated TTC-SC28

I have a Norcold RV fridge. I had major issues with performance, I added an outdoor vent fan, and added a 2-D Cell powered fan inside, which runs for 2-3 month on alkaline (disposable) batteries. I tried Ni-Cad rechargeable D Cells, but their performance was terrible. DO not like throw away batteries, so I added this with rechargeable 18650 Lithium Batteries- which do not like the cold. Already had chargers for 3 batteries and extra batteries, so it fit nicely. Frankly, I bought the 600 hour bs (25 days!) of usage on low- this is simply a deceptive falsehood. In reality, maybe a week of life, so it is a regimen. I change and recharge these batteries around 20-25 times before I change the D Cells. So make your own judgement, it appears to work in concert with the D Cell fan.

Very poorly constructed did not work

Was not worth the cost. The bottom doesn’t stay in place . Plus it cost me twice as much for the rechargeable batteries than the fan it self.Gave it a second chance .. still it’s a defective battery box door. . It won’t stay closed.

18650 rechargeable batteries are great but they aren't designed to be user installed so they aren't readily available. Products that use them should come with them and have built-in charging mechanisms. Everything the vendor says about them is right, they are high capacity and reduce waste but they need to include them with the product.If you happen to have some around as we did, this might be a good choice. We ordered it to keep the air moving in our kegerators to keep the temperature even throughout as we've had some issues with the bottom freezing.Overall mixed about the "TITAN Rv Refrigerator Fan Rv Fridge Fan Rv Vent Fan Rv Fan Boost the Efficient of Fridge Vent & Exhaust Mini Design Ultra High Voulm Air Flow with On/Off Switch Smart Battery Power Operated TTC-SC28", can't recommend most people buying it.

Mr. dissatisfied-Got the product the refrigerator circulator air circulator never worked purchased batteries for nothing

I bought the appropriate batteries for this unit..charged them fully..inserted--NOTHING ! Does not turn on. This product is useless!

Good Luck finding batteries to fit this item. It requires Three Lithium Ion 1865 Batteries.

While it come with a charger and re-chargeable batteries, it doesn't run for more than a few minutes. Then the batteries run out of power in about 2 weeks. Don't waste your money, like I did.
