## 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.

### ⭐⭐⭐⭐ 







  
  
    Good versatile fan.
  

*by R***T on Reviewed in Canada 🇨🇦 on 22 June 2022*

I bought this fan to use in situations where I don't have power.  It ran for about 5 hours on the internal rechargeable batteries.  I would have preferred a few more hours.  It also takes a long time to recharge the battery using the AC plug but you can run the fan at the same time, which is nice. It moves a lot of air.

### ⭐⭐⭐ 







  
  
    Short Life Span Overall
  

*by W***Y on Reviewed in Canada 🇨🇦 on 16 August 2019*

Battery life is short at the lowest speed and the battery became un chargeable after about a year of seasonal use. Can still be used with the cord, though.
