## Questions & Answers

**Q: What is the battery life at high and low speeds?  Thanks.**
A: I just got 3 of these on a hot summer day. Although I have AC, I don't push it hard to save on the electric, so use fans to help make the AC feel a little cooler, & circulate some of the cool air to the bathroom. I also couldn't find a fan that would fit in my tiny bathroom window. These fit perfectly. I immediately tested them out. My "D" cell rechargeable Tenergy batteries were purchase around 2002-2003. They were old, well used & through a fire so suffered severe heat & steam. Rated at 10ah (10,000 mah), I'm sure as old as they are, they're only half the the power of their original new Ah rating... probably worse. Rechargeable batteries deliver almost constant current until they're just about fully discharged. So I expected full speed from the fans until the batteries were almost wore out, & that's what I got. On my very old worn rechargeable "D" cells, all 3 fans ran at full speed on high with no change for 23 hours. By 24 hours they had slowed down to about the speed they would be on the low speed with fresh batteries. By 25 hours they slowed down so much that I could only feel a breeze by putting them close to my face. So on my very old batteries who's life expectancy was exceeded many years ago, I got 24 hours of useful continuous breeze. Some say they can't feel a breeze unless they're within a foot or 2 from it. Not true. They're either using some pretty bad or worn out batteries, or got a defective one. Placed just outside my bathroom door to circulate some of the cool AC air into the bathroom, I could comfortably feel a breeze from the toilet 6 feet away. But beware this thing probably only draws a watt or less. It will not blow as hard as a 35-150 fan. It's a small portable device that will provide a mild breeze, but not from across the room. In shorts & a T-shirt it definitely felt good from as much as 6 feet away for 24 hours.

**Q: is there a way to make it blow cold air without dripping water on it?**
A: I'm pretty sure you were thinking of those condenser fans (?) that use water by creating a fine mist and as it blows air it has the ability to cool the area by 15+ degrees. Its not a dumb question. Try a personal mister in front of it (mist being directed towards you not the fan) and that will feel much cooler. That's how humans cool down, moisture (sweat)...air...
Ice in front of a fan can in fact drop the temp of the air traveling over it but you have to be close to the source or the air gets warmed again by time it reaches you.  As far as the product goes....o2cool fans are great! Best wishes

**Q: Is there an adapter that can be purchased for the 02COOL 5" Fan?**
A: Its a DC 5521 plug also the older model does have the dc plug I'm not sure if there is one without exactly. This is the plug I use to run the fan off a portable charger https://www.amazon.com/dp/B07J6NQ1KN/ref=cm_sw_r_u_apa_fab_AoPGFbC78RXG7

**Q: Is there a way to rig this for use as a tent ceiling fan?**
A: Being a tent camper and a person who likes to make things work, I would say yes, you could. It would probably have to be hung upside down with a heavy grade string or a small rope around where the battery housing connects to the fan part. I hope this idea helps.
