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 ### ⭐⭐⭐⭐⭐ Got it for radar detector *by on Reviewed in the United States July 26, 2023* 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 workOne 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. ### ⭐⭐⭐⭐⭐ work with milwaukee heated jacked. *by on Reviewed in the United States January 12, 2026* worked perfect. if you purchased a milwaukee heated jacket from home depot you need this to be able to run the jacket off of a portable phone charger. ### ⭐⭐⭐⭐⭐ Got this to replace a cheap car 12v adapter that failed. *by on Reviewed in the United States February 2, 2025* This thing has honestly surprised me. I got it to replace the cheap "cigarette lighter" power thing for an in car child camera system that failed, and it works great off a normal 5V USB port. I've also used it for a raspberry pi CM4 on the official IO board (no PCI-e stuff, just the CM4 running Raspbian and a couple other operating systems for some short term testing, but it worked great! Even handling my overclocking of the CM4 to what I believe is the limits of the silicon.) ## Frequently Bought Together - FARSENSE USB DC 5V to 12V Step Up Power Cable(3ft), USB to DC 12V Adapter with DC Jack 5.5 x 2.5mm(3.5 x 1.35mm), USB Boost Converter Supports LED Indicator - iGreely USB Voltage Step Up Converter - DC 5V to 12V, 3ft Cable with DC Jack 5.5 x 2.5mm or 5.5 x 2.1mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/406924295-dc-5v-to-dc-12v-usb-voltage-step-up-converter](https://www.desertcart.co.uk/products/406924295-dc-5v-to-dc-12v-usb-voltage-step-up-converter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-21*
