Took me a bit to find this! The speed on this AC/DC can be adjusted, which is suitable for a nail drill. I’ve owned it for about a year now with zero issues. Review: Works well, but minimum voltage is 3.45 (measured) instead of 3.0 - I used this for a hot wire cutter & it worked "as is" as long as the wire was long enough. For my use with a 1" wire I added a 3 Ohm resister in series & it works fine. ## Features - 【Adjustable Voltage Power Supply】Input parameter: AC 100-240V 50/60Hz , Variable power supply voltage can be adjusted from 3V to 12V DC( 3V 4V 5V 6V 8V 9V 12V adjustable), Wattage Max 60W. - 【Accuracy LED Voltage Display】The universal power supply has built-in LED, which can display real-time voltage and better help you control the charging status in real time. - 【Multiple Protection】The adjustable power supply provides overcurrent protection, overvoltage protection, overload protection, and short circuit protection to safeguard your safety. - 【95% Efficient Power Adaptation & Long Life】The ultra-low interference and stable voltage of the universal ac adapter contribute to achieving efficient power supply adaptation with 95% high efficiency and long lifespan. - 【Widely Used】3-12v 5a variable dc power supply are perfect use for liquid crystal display, LED light bar, motor, light cat, mini TV, 2.5 inch mobile hard disk, mobile DVD, TV box, wireless audio and video equipment, charging equipment, MP3/MP4, small table lamp, router, switch, game machines, telephones, lanterns, cameras, surveillance equipment, massagers, beauty instruments, motors, controllers and other household / portable devices.(Check dc jack before buy :5.5x2.5mm,compatiable 5.5x2.1mm). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R4NK3D1 | | Amperage | 5 A | | Best Sellers Rank | #645,525 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #3,029 in Power Converters | | Brand | Yetaida | | Color | black | | Compatible Devices | Adapter, Cameras, Cellular Phones, Controller, Lanterns, Monitors, Telephone | | Compatible Phone Models | liquid crystal display, LED light bar, motor, light cat, mini TV, 2.5 inch mobile hard disk, mobile DVD, TV box, wireless audio and video equipment, charging equipment, MP3/MP4, small table lamp, router, switch, game machines, telephones, lanterns, cameras, surveillance equipment, massagers, beauty instruments, motors, controllers and other household / portable devices Compatible Phone Models liquid crystal display, LED light bar, motor, light cat, mini TV, 2.5 inch mobile hard disk, mobile DVD, TV box, wireless audio and video equipment, charging equipment, MP3/MP4, small table lamp, router, switch, game machines, telephones, lanterns, cameras, surveillance equipment, massagers, beauty instruments, motors, controllers and other household / portable devices See more | | Compatible Power Plug Type | Type A - 2 pin (North American) | | Connectivity Technology | DC Barrel | | Connector Type | Barrel Connector | | Current | AC/DC | | Current Rating | 2 A, 3 A, 5 A | | Customer Reviews | 4.3 out of 5 stars 167 Reviews | | Enclosure Material | Plastic | | Form Factor | Box | | Frequency Range | 60 hertz | | Input Voltage | 240 volts | | Item Weight | 0.24 kg | | Main Power Connector Type | 2 Pin | | Manufacturer | Yetaida | | Mfr Part Number | ND-Adjustable-Power-Adapter | | Model Name | Adjustable Power Adapter | | Model Number | 3-12V Adjustable Power Adapter | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Power Levels | 9 | | Output Current | 5 A | | Output Voltage | 12 volts_of_direct_current | | Plug Type | Type A - US style | | Power Plug | Type A - 2 pin (North American) | | Power Source | Corded Electric | | Special Feature | Adjustable Voltage: 3-12v ,Switch the one you need | | Special Features | Adjustable Voltage: 3-12v ,Switch the one you need | | Specification Met | UL | | UPC | 020064713678 | | Unit Count | 1 Count | | Voltage | 12 volts | | Wattage | 60 watts | ## Images ![100-240V to 3-12V 5A Power Supply Adjustable Universal - Image 1](https://m.media-amazon.com/images/I/71UuqevVJ3L.jpg) ![100-240V to 3-12V 5A Power Supply Adjustable Universal - Image 2](https://m.media-amazon.com/images/I/7144OkzUuBS.jpg) ![100-240V to 3-12V 5A Power Supply Adjustable Universal - Image 3](https://m.media-amazon.com/images/I/71qBmJEbpoS.jpg) ![100-240V to 3-12V 5A Power Supply Adjustable Universal - Image 4](https://m.media-amazon.com/images/I/61SXE09hnVS.jpg) ![100-240V to 3-12V 5A Power Supply Adjustable Universal - Image 5](https://m.media-amazon.com/images/I/61mp9Ul3sGS.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Adjustable Speed! *by L***O on June 19, 2021* Purchased this AC/DC because the one I have and use for my nail drill gave out. Took me a bit to find this! The speed on this AC/DC can be adjusted, which is suitable for a nail drill. I’ve owned it for about a year now with zero issues. ### ⭐⭐⭐⭐⭐ Works well, but minimum voltage is 3.45 (measured) instead of 3.0 *by J***T on September 11, 2020* I used this for a hot wire cutter & it worked "as is" as long as the wire was long enough. For my use with a 1" wire I added a 3 Ohm resister in series & it works fine. ### ⭐⭐⭐⭐ nice little 3.2v to 12.6v at max ABOUT 3.5 AMPS DC POWER SUPPLY *by B***I on September 16, 2020* POSITIVES: very small and nice looking, I like the green display, very handy .Regulation is just ok for this little thing.NO LOAD data: display=4.02 V(good luck in adjustment) ;output jack=3.8 V. 3.5 AMPS (1 ohm load) data: display=3.9V ;output jack=3.5 V so you have at 3.5 Amps , a drop of 0.3 V(10 % regulation) NEGATIVES: Max current is not 5 Amp but ABOUT 3.5 Amp. Full range data: display=11.8 V, load=3 ohms,output jack=11.2 V (3.7Amps) and 11.7 V in no load; so you have at 3.7 A/11.7 V (full range current/voltage) a drop of 0.5 V(about 5% regulation) so regulation is better at higher voltages Case Temperature data at room temp of 78 deg F : For 20 minutes , on 3 ohms load, at 11 V on the output jack(3.6 A), the case temperature got to 108 deg F and the 3 ohm/30W resistors(the load) got to 250 deg F (there are no vents in the case; the case is air tight and the case stays on wood table;not heat conductive then) so I suggest making a lot of small holes all over the case(make sure you remove the guts first, GOOD LUCK!) IF you plan to use this thing at full range voltage/current. , The adjustment is relative continuous(no steps) but very difficult to get anything under 0.5 v variations within the 3.2 to 12.6 volt range. The voltage display is OFF (is bigger 0.2 V average) than the actual voltage on the output jack. --- ## 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.sn/products/139300096-100-240v-to-3-12v-5a-power-supply-adjustable-universal](https://www.desertcart.sn/products/139300096-100-240v-to-3-12v-5a-power-supply-adjustable-universal) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-19*
