Review: Got it for radar detector - My truck only has USB, no 12v outlet, as most newer vehicles do. So I got this to run a radar detector off the USB port in my dash. I have a 12v Cobra radar detector and this USB cable seems to work fine, so far, powering it up off my truck USB port. I've read most radar detectors draw under 1 amp so this little converter should hold it with no problems. BUT I wouldn't try to power anything bigger like a 12v air compressor, I don't think it would work One bummer is that the USB port in my truck is always on so I have to unplug this before I leave the truck, which is not a huge deal (until it kills my battery one day). Overall it's pretty useful and inexpensive, so it's worth getting. I have a feeling a lot of people need this and don't know about it. Also I ended up using the tip adaptor to fit my radar detector and it fit perfect. I ordered another cable like this and the tips did not fit. ## Features - 【Electrical Parameters】USB step up boost converter input voltage: DC 5V;output voltage: DC 12V;max output current:1A;convert ratio: 80%-90%.Note:not suitable for high current equipment. - 【Appearance Parameters】Appearance: frosted shell;weight: 39g; size: 50mm x 18mm x 9mm.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Plugged in and it works *by A***R on February 13, 2026* Works as advertised. ### ⭐⭐⭐⭐⭐ Got it for radar detector *by A***N on July 26, 2023* My truck only has USB, no 12v outlet, as most newer vehicles do.
