I’m using it with an old 5V USB charger to power two Arctic P12 fans, and it does exactly what it’s supposed to do. Setup was easy and everything works reliably. It’s a great solution if you want to run PC fans without using a full PC power supply. Very happy with it — simple, effective, plugs fit well, good cable quality and good value for money. ## Frequently Bought Together - Gebildet Full Speed 12V Voltage Step-Up USB to Dual 3-Pin and 4-Pin PC Fan Sleeved Power Adapter Cable - Noctua NF-P12 redux-1700 PWM, High Performance Cooling Fan for Desktop, 4-Pin, 1700 RPM (120mm, Grey) --- ## 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.hr/products/671735988-full-speed-12v-voltage-step-up-usb-to-dual-3](https://www.desertcart.hr/products/671735988-full-speed-12v-voltage-step-up-usb-to-dual-3) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-17*
