TANHEYIN 18V to 12V Buck Converter — 240W, Milwaukee M18 Battery Compatible

Overview

The TANHEYIN 18V to 12V buck converter transforms compatible Milwaukee M18 batteries into a steady 12V DC power source. Delivering up to 240W (20A max), it supports a range of Milwaukee models (e.g., 48-11-1850, 48-11-1820, 48-11-1860, 48-11-1880, 48-11-1840) and notes that the battery is not included. This setup makes it easier to run 12V devices from your existing 18V pack, opening up new possibilities for projects and playtime.

Key protections that matter

Built around a smart control chip, this converter emphasizes safety for both battery and device. It includes safeguards for low and high voltage, over-current, short circuits, overload, and overheating. For correct wiring, remember: yellow is positive, black is negative.

• Low-voltage auto cut-off at 15.2V to help prevent deep discharge
• Over-voltage and over-current protection for system safety
• Short-circuit and overload protection to reduce risk
• Overheat protection to maintain performance under load
• Integrated with a 30A fuse to handle surges safely

Versatile uses for every project

Whether you’re powering a power wheel adapter, ride-on toy cars, RC vehicles, LED lighting, or work lights, this buck converter converts 18V battery power into a reliable 12V supply. It’s suitable for golf carts, small lawn gear, DIY builds, and other 12V applications where consistent output matters.

• Power wheels, ride-on toys, and RC cars
• 12V LED lighting, work lights, and small appliances
• Golf carts, lawn equipment, and compact tools
• DIY projects and custom electronic builds

Simple setup and practical tips

Install is straightforward: connect the battery to the adapter, then wire the terminals to your device. The unit features a heat-resistant ABS shell and two mounting screws for secure placement. If unused for long periods, remove the battery to prevent unnecessary discharge.
