## Questions & Answers

**Q: Is this "center negative".**
A: No, center positive.

**Q: Which end of cable is 5 volts input and which is 12 volts output?**
A: 5 volts is the USB-A input side. The output is on the barrel plug and is 12V.

**Q: I have a 5v/3a power bank that I'm planning to use to power up a 12v 1.5a monitor. Will this work?**
A: The max output current for 12V is 1 amp. Your monitor requires 1.5 amps so technically the draw over the rating of the adapter and will not work.

**Q: Could this be used for audio equipment as a 12v trigger to activate (an amplifier) from another device that has USB but no trigger output?**
A: Probably will work. 
I used a 5v usb connector in my car to feed this device. It gave me a 12 v output to supply a radar detector.
