Power your 12V accessories from a 20V battery

The IIXWUQ 20V to 12V buck converter is a compact, robust voltage regulator designed to convert higher Dewalt battery voltage into a stable 12V output for a variety of devices. Its design centers on reliability and safe operation, so you can tackle projects with more portability and fewer power worries.

Key specifications at a glance

Designed for hard-wearing DIY use, it delivers a regulated 12V output capable of up to 20A (240W) from a 18–20V input. It is not a charger; connection is power transfer from the battery to connected equipment only.

  • Input: 18–20V DC; Output: 12V DC
  • Max current: 20A; Max power: 240W
  • Efficient operation via synchronous rectification for stable performance

Smart safety features

  • Over-Current protection to guard both device and regulator
  • Over-Discharge protection with auto shut-off if battery falls below 14.4V
  • Over-Load and Over-Voltage protections
  • Under-Voltage and Over-Heat protections with Short-Circuit defense

Real-world uses

Think of powering motors, robotics modules, LED strips, small fans, or LCD displays directly from a DeWalt 20V battery. The 12V output can help you extend on-site setups, test rigs, or portable kits where 12V devices are preferred or required.

  • Ideal for DIY robotics, model vehicles, and home workshop projects
  • Supports LED lighting, fans, monitors, and other 12V components

What’s included and how to wire

  • 1 x Step Down Converter
  • 6 x 30A replacement fuses
  • 1 x wiring terminal block

Wiring tips: connect the positive lead to the red line and the negative lead to the black line for correct polarity. For storage, remove the battery from the adapter when not in use to extend life.

Notes for buyers

Remember this unit is designed to output power, not charge batteries. It pairs with Dewalt 20V/18V Li-ion packs and integrates safely with a range of DIY applications where a 12V source is helpful.
