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 ### ⭐⭐⭐⭐⭐ Works great *by G***A on July 13, 2026* Bought this to power my screen for my camper camera, plugs into my usb port and maintains voltage for the screen to operate. Very compatible for not just the camera but other devices as well. Cord has plenty of length and like that it shows the voltage. For the money I would definitely buy again and recommend ### ⭐⭐⭐⭐⭐ Work *by L***E on August 23, 2026* I purchased this to replace the adapter on my backup camera because the USB was damaged. It fit it came with different size adapters and it seems well made. No complaints. ### ⭐⭐⭐⭐⭐ This little unit does the job and is well regulated. *by J***S on June 20, 2024* 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 Amazon. 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. ## Frequently Bought Together - FARSENSE USB DC 5V to 12V Step Up Power Cable(3FT),USB C to DC 12V Adapter with DC Jack 5.5 x 2.5mm(Compatible with 5.5 x 2.1) and 3.5 x 1.35mm, Boost Converter Supports Voltage Display - 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.es/products/571647749-usb-5v-to-dc-12v-usb-voltage-step-up-converter](https://www.desertcart.es/products/571647749-usb-5v-to-dc-12v-usb-voltage-step-up-converter) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-10-07*
