## Questions & Answers

**Q: Can you use this on a usb power source that is 12v ?**
A: This will not negotiate 12v from a USB charger. It will always draw 5v from the charger and boost to 12v

**Q: Can this be used to send ASCII commands from a PC to hdmi multi viewer product?**
A: I don't think so. This is for powering a PC fan using a USB power source. It's only 3 pins as well so it lacks extra data communication.

**Q: Will this work with a 12v 0.12a fan? its a be quiet shadow wings 2 120mm fan.**
A: It should work with any 12v fan. I had no issue using it on a similar fan.

**Q: Does the step up circuit have a frequency noise issue?**
A: I never noticed anything. I had an ITX motherboard in an enclosed space so I used this and an exhaust fan. Sounded like a normal 120mm fan
