I am using to operate a motorized window that is 24v. ### ⭐⭐⭐⭐ I wish they had used something slightly better than crappy cast aluminum for the outer casing *by M***N on Reviewed in the United States 🇺🇸 on October 6, 2016* I wish they had used something slightly better than crappy cast aluminum for the outer casing. The mounting holes broke pretty quickly, but the electronics have held up well under pretty harsh circumstances. Several zip ties are holding it in place now. ### ⭐⭐⭐⭐⭐ 12v to 24v for Access Control Project *by T***K on Reviewed in the United States 🇺🇸 on January 13, 2018* Absolutely great. These were used in an an access control system to send 24v to electronic doors. It allowed the use of a single 12v power supply for both the 12v and 24v loads. A captive-screew terminal or set-screw terminals would have been preferred for faster wiring. But, all in all, they did their job perfectly, providing a rock-solid 24v output. --- ## 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.pl/products/7187562-ex-electronix-express-78dccon12v-120w-step-up-boost-converter-voltage](https://www.desertcart.pl/products/7187562-ex-electronix-express-78dccon12v-120w-step-up-boost-converter-voltage) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
