Review: Absolutely the greatest fan that runs on batteries! - I bought this fan that runs on batteries for a specific reason. We have a number of tornado watches here in Georgia and when my two little rescue dogs and me go into our safe room, there is no air circulation in there. The dogs would get extremely hot because sometimes we would be in there for hours or sleep there overnight. When I saw this fan I thought it would be the perfect thing since there is no electricity in the safe room. The fan produces a lot of cool air which is just what we needed. The fact that it runs on batteries was the reason I purchased it originally and I am so happy with this fan. It also has little feet so it can stand upright and it is very light weight and has a carrying handle, if needed. I cannot say enough about the sellers of this product. They were so kind and generous about everything and I highly recommend them as well as the wonderful fan!
Review: Great fan for camping - This is a very nice fan for camping...or even around the house. On built in batteries and 12v, it doesn't move as much air as when its plugged in, but for the smaller spaces it will be used in when powered by battery/12v, it works great. The swiveling fan means you can get it to blow air where you need it. It's very light and relatively small and easy to pack even in our pop up camper. At home we use it in the rooms around the house that need a little bit of extra air movement at night. Overall its quiet and moves air well. The charging can take some getting used to at first, but once you do its easy to remember--just remember to set it to off before plugging it in....and then move it to low or off or high to start it charging. If its set to one of the other positions when the AC charger is inserted, it won't charge.

## Features

- ENERGY EFFICIENT COOLING: Smart Power technology automatically selects lowest cost power option so it won’t run out of power quickly. Desktop battery powered fan tilts for oscillating air flow.
- USB POWER PORT FOR SMART PHONES: With a USB power port you can charge your cell phone, laptop, and other mobile devices. This comes in handy during a power outage or emergency.
- POWERFUL 10-INCH BLADES: Treva by O2COOL wireless and electric fans feature 5 patented fan blades with 2 powerful speeds so you can enjoy your own personal refreshingly cool air.
- COMPACT DESIGN FOR TRAVEL: Take cool air anywhere! This portable fan is sleek and compact making it perfect for camping. It features a convenient flip-up handle that makes it easy to carry.
- MULTIPLE POWER SOURCES: Don’t worry about running out of power. Fan operates with plug-in AC or DC adapters (included), use 8 D-Cell batteries (not included) or use built-in rechargeable batteries.

## Questions & Answers

**Q: What happens to rechargeable battery when fan is stored for a while?**
A: They do go bad after some years. We loved this fan, still use it, but miss the rechargeable option.

**Q: how is this newer model ($45)  different from the older model for $30 more**
A: Hello, I'm not sure what the "older" model was, ours was a 10" 12v that we loved.The newer  model has Smart Power technology. It chooses which power option is most efficient. It will run on AC, DC, has it's own rechargeable batteries and you can also use and addition D-cell batteries. That is something that is now made too clear when you are shopping for them. It has internal batteries and you can add D batterries, so you have the option of 4 power sources. The fan motor is also improved to run on less power...giving you longer run time. It has a USB port also. It is a good fan. I'd shop around, I paid more for ours, but I see you can get them under $45 now.

**Q: Is it 110 or 220 volt**
A: The charger indicates an input of 110-240V.  The two prongs appear to be for 110 standard wall outlet.  So an adapter to 240V could be required.

**Q: What is the difference between this model and black and orange model?**
A: Thanks for your question. The only difference is the color.

### ⭐⭐⭐⭐⭐ Ran one for a year and had no extra noise or trouble
*by K***S on September 14, 2021*

Ran one 24/7 for about 10 months and had no trouble. I set it on battery mode about once a week. Every now and then it will speed up and then slow down like the electric is bad but it does it in battery mode also. No real problem. I recommend it and now have 3. I will not buy a box fan anymore. I live @ 7000 feet and only need a swamp cooler and fans. I also use the USB charger port quite a bit. Charger status light comes on a lot but doesn't seem to bother it. Switch is pretty stiff on the new one but I think it will break in. Internal battery lasts for hours. It's pretty quiet and worth the money. I don't think you'll regret it.
