Review: High-quality finish and very reliable voltage control - This is a high-quality universal adapter that offers a massive amount of utility. The adjustment dial is smooth, and the voltage remains stable once set. It’s quick and easy to swap the tips, and the 72W capacity means it handles larger electronics like monitors or LED strips with ease. My only minor note is that the dial is quite sensitive, so double-check the LED screen before plugging in your device—but for performance, it’s a solid, reliable choice.

The selection of tips is great, as is the reverse polarity adapter, although I would say it would have been better to have a physical switch on the main PSU to reverse the polarity rather than the adapter cable. It you forget you have the adapter installed, you run the risk of damaging the equipment you intend to power. You have to look at the main unit to set the voltage anyway so a switch for polarity would have been helpful. Works well and luckily didn't need to power anything below 3v as this is the lowest setting. ## Frequently Bought Together - Wefomey Universal Power Supply 3V~24V 3A 72W Adjustable Variable AC/DC Adapter Charger, 100V-240V AC to DC Converter with LED Voltage Display & 14 Tips & Polarity Converter - Soldering Iron Kit Electric, Soldering Iron 90W Welding Tools, Adjustable Temperature 180-480℃ Soldering Kit, Digital Portable Solder Iron Kit with 5 Solder Tips, Solder Wire, Mini Stand --- ## 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.za/products/641325831-wefomey-universal-power-supply-3v-24v-3a-72w-adjustable-variable](https://www.desertcart.co.za/products/641325831-wefomey-universal-power-supply-3v-24v-3a-72w-adjustable-variable) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
