Installation is simple thanks to the clear terminals and small footprint, and the board feels sturdier than most budget options with solid solder joints and a responsive dial. Functionally it does exactly what you want — stable output, wide adjustment range, and no noticeable heat buildup — making it useful for fan tuning, small motors, or battery‑powered projects where efficiency matters. A dependable little unit that performs well for the price. Review: WORKS GREAT and INEXPENSIVE! - FANTASTIC ITEM! Great price! Works perfectly as described. I needed something to make a 3V DC motor run at a slower speed. Unfortunately I’m not well versed in electronics. I was going to ask someone on FB what to do. Then I thought of asking google AI what to use. It came up with this very controller. No instructions but super easy to install. The four terminals are clearly marked: Motor plus and minus, and Power source plus and minus. Your wires are screwed in with tiny screws and held firmly. Can’t be any easier! It’s small and doesn’t take up much room, and the control knob clicks when put turned off and on. There’s a pilot light showing when it’s on. Two for $7 with free Prime shipping! You can’t beat this! ## Features - Adjustable duty cycle: 0%-100% - Maximum output power: 30W - Maximum continuous output current: 2A - Input voltage: DC 2.2V-15V; output voltage: 1.8V-15V - Equipped with a 2A self-recovery fuse, which will automatically disconnect if the current is too large, and will automatically recover after the fuse cools down ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09P6D5TMV | | Best Sellers Rank | #37,627 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #7 in Electrical Motor Controls | | Brand | BOJACK | | Brand Name | BOJACK | | Color | black | | Customer Reviews | 4.4 out of 5 stars 295 Reviews | | Display Type | LED | | Included Components | no | | Manufacturer | BOJACK | | Material | Copper | | Material Type | Copper | | Model | BJ-1803BK | | Part Number | BJ-1803BK | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 762917045412 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** BOJACK - **Color:** black - **Display Type:** LED - **Material:** Copper - **UPC:** 762917045412 ## Images ![BOJACK Low Voltage DC Motor Speed Controller PWM 1.8v 3v 5v 6v 12v 2A 30W Adjustable Driver Switch 1803BK 1803B (Pack of 2 Pcs) - Image 1](https://m.media-amazon.com/images/I/71roWBIUNVL.jpg) ## Questions & Answers **Q: Does this draw any power when switched off?** A: I guess it will draw few mA for 555 timer. **Q: does this controller work in forward/reverse mode?** A: no, not specifically. For most types of DC motors, you could use an appropriately rated switch (DPDT rated for more than the amperage of the motor) to reverse polarity, and thus direction easily enough... **Q: will this work on a car heater fan?** A: No. It is not meant for that. **Q: will this work as a dimmer for LEDs?** A: If your leds are 12V DC led strip up to 5 amps, then yes you can use it as a dimmer. In fact, there is a LED on the board for indication and its brightness shows the PWM duty cycle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Durable Little Controller With Great Range and Precision *by B***C on March 6, 2026* This compact PWM controller handles its full 1.8–12‑volt range cleanly, giving smooth, predictable speed control to a 12‑volt fan without any stutter or dead spots.
