Reverse polarity converter: 5.5mm x 2.1mm Power cable length: 6.9ft / 210cm Safety Compliance: FCC / CE Working Temperature: -20~50℃ Ambient Humidity: 5~95% Non-Condensation Weight: 1.1 lb / 500g Fetures: -High quality components. -Application:Can be used for DC moto speed control,light dimmer,laptop,printer and so on. -Noted: 1.The adjust power within the range 3V~24V(±5V) 2.The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~24.5V. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply's voltage range is 3V~24V, not 3.5V~24.5V. Package included: 1 x 120W Universal Power Supply Adapter 1 x Reverse polarity converter cable 14 x DC Tip Review: Good quality - This is such a useful power supply. From 3v-24v 3 amp 72watt supply in increments of 0.1v, with clear led display. Works well, stable, runs cool, has screw hole fitting for wall/floor mounting. I am using some of these in my recording studio on old/fragile/expensive equipment. Had no problems. I'm sure they would be equally good on railway layouts etc. Be aware it takes a careful hand on the 'knob'.. to set the exact voltage, but once it's done. it's done. Review: Easy - I’m not technical, but I used it to revive my laptop. Great thing, easy to use. ## Features - ▶【High Quality Adjust Power Supply】Input:AC 100~240V,50/60Hz;Output:DC 3~24V Adjustable,Output current Max 5A,Wattage Max 120W(Noted:DO NOT OVERLOAD);It can provide any voltage between 3~24V,such as 3V 4.5V 5V 5.5V 6V 9V 12V 14V 15V 16V 18V 19V 19.5V 20V 22V 24V,etc or any amp less than 5A,such as 300mA,1A,1.5A,2A,2.5A,3A.Built-in LED displays real-time voltage,which helps you control real-time condition of charging,in case that wrong voltage regulation damage your device. - ▶【Adjustable Voltage With 14 Plugs DC Tips & Reverse Polarity Converter Cable】It comes with an original 5.5x2.5mm tip and 14pcs frequently used tips: 6.5x4.4mm+Pin, 5.5x2.1mm, 5.5x3.0mm+Pin, 5.0x2.5mm, 6.3x3.0mm, 5.5x1.7mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, Micro-USB, Type-C and DC terminal connector.

Great thing, easy to use. ### ⭐⭐⭐⭐ Does what it says *by A***R on 7 August 2023* I bought this to replace a chinese lead which came with a large device with remote control that overheated to over 70degrees C in less than an hour. This works with it and feels safer and has not reached the temperatures . I'm not an electrician , but the adapter cuts out when it reaches 12volts. As the chines machine did not state this information, I am assuming that is the max power so i run it below, as its variable power remote control and works. The seller was also helpful. ## Frequently Bought Together - 3V~24V 3A 72W Adjustable Power Supply Adapter,DC 3V 5V 6V 9V 12V 15V 18V 19V 20V 24V Universal AC/DC Adapter,100V-240V AC to DC Converter with 5.5x2.5mm 14 Tips & Polarity Cable for LED Strip Laptop - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - TUOFENG 28 awg Solid Wire-Solid Wire Kit-6 Different Colored 15 Meter spools 28 Gauge Jumper Wire -Hook up Wire Kit --- ## 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.id/products/457538562-3v-24v-3a-72w-adjustable-power-supply-adapter-dc-3v](https://www.desertcart.id/products/457538562-3v-24v-3a-72w-adjustable-power-supply-adapter-dc-3v) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
