Review: Great 5v to 12v step up usb to dc adaptor. - Works great for what I needed it for. I wanted to replace my DC plug for my gun safe led lights as the original plug was bulky and took up too much space on the built in power strip so I wanted something that took up less space and came across this and it worked out perfectly. Quality seems good and is able to power up the led lights in my safe.
Review: This little unit does the job and is well regulated. - I was quite happy to find that this small unit not only lives up to its specs (12 volts @ 1 amp) but also displays this on a digital display. It will start to drop just a bit once it hits around 980 mA and it Will drop out if you exceed 1 amp by even 100 mA. Also note that if yo run it close to the maximum, it will run quite warm. This didn't seem to effect its performance though. I was using it to power a portable DVD player. It ran needing about 670 mA to 800 mA depending on whether the volume was low or high and if I was using a Fire stick or not. It was pulling about 1.3 to 1.7 amps from the USB source which in this case was a battery bank. In my case, the included adapter didn't fit my player, but I didn't expect it to. You can find adapters on desertcart. Just be aware that this units polarity is the more common tip +. If you have a tip - device, you will need to get an adapter to reverse the polarity or cut the cable and do it yourself which will void the warranty. This small converter does work very well for extended periods of time and I've been very happy with it. Just be aware that it will not exceed 1 amp. It also won't exceed a 2.4 amp draw from your source. So, it's also quite efficient. At this price you really can't go wrong.

## 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.
