We recommend you to use this 12V 20A 240W power supply to power devices less than 192W. 110V/220V must be selected by switch before using to avoid damaging. Please change the switch to 110V for USA/CA and 220V for EUR. Package included 1 x 12V 20A Power Supply (Power cord is NOT included.) Superior Safety Built-in safeguards to protect against over voltage, over current, overheat, short-circuit, which will provide ultimate protection for you and your devices. Premium Quality The shell is made of aluminum. Cellular structure design can enhance air convection and speed up heat dissipation. Premium quality materials make it more solid and durable. ±10% Voltage Adjustment The output voltage can be regulated by ±10%, from 10.8V to 13.2V, which greatly expand its application range. It can supply with any current ( less than 20A) your device draws, such as 5A, 10A, 15A, 20A. Three Output Channels With three independent output channels, it can power more devices. The maximum output of each channel can reach 20A 240W. Total output power of the three channels is 20A 240W. Stable Output Built-in advanced synchronous rectifier smart chip and EMI filter, convert fluctuating voltage to stable voltage, effectively reduce electromagnetic interference. Warning! ## Features - Input: 110V/220V AC; Output: DC 12V 20A max. Output voltage is adjustable 15%.

Went to Home Depot for a power cord wasn't sure which was sufficient enough. 13 amp 125volt or 15 amp 125volt?** A: Either cord will work - the unit has a rated output of 180 watts and is protected for overload. If you hate math - watts=volts x amps. 15 amps is for the output at 12 volts - 15 x 12 =180watts. On power side at 115/120v, the amperage will be significantly lower - 180watts/120volts = 1.5 amps. No grade credit given for this online math course. **Q: what voltage dimmer would you recommend, so i can have 0 to 12 V 20A dc in the output please ? for 15m of led rolls.** A: LEDs are dimmed via PWM, not voltage. You would still use a 12v PWM dimmer **Q: would one of these be acceptable for a peltier cooling power supply** A: As long as the voltage and amps match. I’d pare the acceptable cooler amps down to 70% to be safe. **Q: Can this power supply run continuously? Does it need a cooling fan to do so?** A: I believe it will run continuously at the rated output. At or below the rated output, I've had no requirement for an external fan. The unit appears to be protected with overload protection based on rated output. One note, my unit is not mounted in a air-tight enclosure but utilized as a bench-top unit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on March 8, 2026* ### ⭐⭐⭐⭐⭐ Review *by L***E on May 2, 2024* ### ⭐⭐⭐⭐⭐ Review *by W***S on October 14, 2025* ## Frequently Bought Together - ALITOVE DC 12V 20A 240W Power Supply Transformer Switch AC 110V / 220V to DC 12V 20amp Switching Adapter Converter LED Driver for LED Strip Light CCTV Camera Security System - Stainless Steel 316 Straight Thru Hull Exhaust Skin, Fitting 24mm Tube Pipe Socket Hardware, for Diesel Parking heaters - VEVOR 8KW Diesel Heater, Diesel Heater All in One with Remote Control and LCD Screen, Parking Bunk Heater, Fast Heating Low Noise, Portable Diesel Heater for Truck Van RV Trailer Camper and Indoors --- ## 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.hk/products/58379437-12v-20a-240w-power-supply](https://www.desertcart.hk/products/58379437-12v-20a-240w-power-supply) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-19*
