Been installed 3-4 months now and worked flawlessly. ### ⭐⭐⭐⭐⭐ Does what it says on the tin! *by N***. on 14 December 2025* Working well with the christmas lights. ### ⭐⭐⭐⭐⭐ 240v > 5v PSU *by W***E on 27 January 2026* Does the job, easy to use and works well. One downside would be the terminals connected to the 240v input could do with better protection against electric shock. Perhaps the designer can split the clear plastics flip down lid that protects the 240v input contacts and the 5v output contacts. If you have children around be sure to secure this unit out of reach otherwise there could be a risk of electric shock or electricution ## Frequently Bought Together - 5V 40A Power Supply AC 110V/230V to DC 5V 200W Universal Regulated Power Transformer for LED Strip Lights - 3 pack ESP32 ESP-32S Development Board 2.4 GHz Dual Core WLAN WiFi + Bluetooth 2-In-1 Microcontroller ESP-WROOM-32 Chip CP2102 for Arduino (3PCS) --- ## 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.us/products/162335511-ac-110v-220v-to-dc-5v-40a-10w-switching-power](https://www.desertcart.us/products/162335511-ac-110v-220v-to-dc-5v-40a-10w-switching-power) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
