## Questions & Answers

**Q: Dual output pump, max depth: 60". output: 47.6 gph. is that per output or both outputs combined?**
A: It seems to be both combined with my setup

**Q: What are the dimensions of the pump?**
A: The one you pictured is different from the one I purchased. I bought the red and white one.

**Q: Can this be used as the main pump for a tank? or should it only be used as a backup?**
A: It can be used as a primary on smaller tanks but they function best as a backup.   We have them running on tanks varying from 40g breeders and below..

**Q: It says must be plugged into a "wall outlet" to detect power outage. Does it mean if it is plugged into a power extension, it won't detect outage?**
A: The pump will not turn on automatically if the power goes out.  The pump will stay on if the power goes out.

    Emergency air pump works
  

*by S***. on Reviewed in the United States on June 10, 2023*

I haven't been able to figure out how to set it to turn on when the power is out every 10 seconds. When I pull the plug, it turns on steady.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Nothing special
  

*by R***J on Reviewed in the United States on October 31, 2022*

They work as advertised, the biggest downside is that they do not plug in using a standard usb or usb-c plug. I have 2 of these pumps and lost both of the power supplies during a move. Now they are useless. If i could use a type-c plug like other pumps then i could recommend these. But they don't.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Wish it was quieter.
  

*by D***. on Reviewed in the United States on February 17, 2019*

I have been using it for a month now and have it sitting on half inch of foam behind display tank. The unit is louder than everything connected to my reef aquarium including protein skimmer when percolating. I can even hear it clearly competing with the waterfall between my 2 tanks. It is even louder than the dependable & working ac only air pump it replaces from a national retail chain. That being said I have tested disconnecting power and unit still pumps air. I am currently testing how long battery will run unit & will update review with result. Two other minor things I dislike are all the LED's constantly blink running connected to AC outlet with battery backup. Power cord is really short. All in all at this point I do not think you will find better feature wise.
