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. ## 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/450125344-farsense-usb-to-dc-12v-step-up-power-cable-3ft](https://www.desertcart.co.uk/products/450125344-farsense-usb-to-dc-12v-step-up-power-cable-3ft) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-11*
