## Questions & Answers

**Q: Can it be used on a outside inflatable**
A: Yes, I bought it for a large inflatable snowman but it wasnt powerful enough. Probably fine for a 4 foot one.

**Q: What in the minium dc volt operating range?**
A: I'm using it at 6v and it is working perfectly for my purpose (Powered air respirator). Below 4.5v it struggles.

**Q: Would this work on a Lenovo M720q tiny computer?**
A: I used in an inflatable yard decoration. You would have to measure and check the requirements of your machine.

A: This device is powered by 110vAC, so their is no "positive" and/or "negative" connection. As per the specifications in the AMAZON notes, "4w".

### ⭐⭐⭐⭐ Fan good. Cord/switch is a fire hazard.
*by A***D on June 2, 2024*

The Fan: So far so good. It has maybe 72hrs on it so far recirculating 65C air. I worry about the electronics... but so far it's holding up well. It does not move as much air as some other models, but I knew that when I bought it. For my use, it's plenty good enough. The cord: Throw it away. Or fix it. The switch on this cord is a fire hazard. The wire is poorly crimped and I was able to pull the wire out of the contacts inside the switch. The switch makes kind of intermittent contact when in the ON position... which creates a high resistivity connection... which makes heat... which melted part of the switch. Thankfully I was in the room when the device turned off spontaneously to diagnose why and noticed that the switch was hot. DO NOT USE THIS SWITCH. Or do. It's your choice and I'm not your mom.
