Detailed Description

DC-DC Converters & Battery Adapters

Choose the right power solution for your project. Our DC-DC step-down converters reduce higher DC input voltages to a lower, adjustable output voltage. DeWalt battery adapters provide two outputs: one delivers the battery's native voltage, while the other provides a fixed 12V output with a maximum current of 2.5A.

Whether you're upgrading a Power Wheels ride-on or working on a DIY electrical project, find the right power solution for your setup.

 

High-Power Voltage Step-Down

1.1converter_cropped.webp

Ideal for applications that require reducing a higher DC voltage to the voltage needed by your device.

  • Input: 11–70V DC

  • Output: Adjustable 3.3–24V DC. The output voltage must be at least 2V lower than the input voltage.

  • Rated Power: 336W

  • Maximum Output Current at 12V: 28A

Suitable for: Golf carts, 6V/12V/18V/24V accessories, car audio systems, and DIY projects. Please verify your actual load requirements before use.

Ideal for DeWalt Battery Dual-Voltage Output Applications

spq3012_cropped.webp

Ideal for applications that use compatible DeWalt 18V/20V batteries and require low-voltage protection or dual-voltage output.

  • Battery Compatibility: Supports compatible DeWalt batteries with voltages between 13V and 30V, such as 18V/20V batteries.

  • LVP-30-12V: Provides dual-voltage output — native battery voltage plus a fixed 12V output.

  • Maximum 12V Output Current: 2.5A.

  • Features: Low-voltage protection, voltage display, electronic switch, and more.

Suitable for: Power Wheels upgrades, lighting, speakers, and other compatible loads.

Important: Do not connect devices that exceed the rated current of the 12V output port. Doing so may cause the module to repeatedly turn on and off rapidly.

Ideal for applications that use compatible DeWalt 18V/20V/60V batteries and require low-voltage protection or dual-voltage output.

  • Battery Compatibility: Supports compatible DeWalt batteries with voltages between 13V and 60V, such as 18V/20V/60V batteries.

  • LVP-60-12V: Provides dual-voltage output — native battery voltage plus a fixed 12V output.

  • Maximum 12V Output Current: 2.5A.

  • Features: Low-voltage protection, voltage display, electronic switch, and more.

Suitable for: Power Wheels upgrades, lighting, speakers, and other compatible loads.

Important: Do not connect devices that exceed the rated current of the 12V output port. Doing so may cause the module to repeatedly turn on and off rapidly.

DeWalt Battery Step-Down Converter Kit

spjyq_cropped.webp

Ideal for applications that require stepping down DeWalt 18V/20V battery power to lower voltages, such as 6V or 12V.

  • Battery Compatibility: The adapter supports compatible DeWalt batteries with voltages between 13V and 30V, such as 18V/20V batteries. The step-down converter supports an input voltage of 11–70V DC.

  • Output Voltage: The output voltage must be at least 2V lower than the input voltage. The step-down converter provides an adjustable output range of 3.3–24V DC.

  • Features & Applications: The battery adapter includes low-voltage protection, a voltage display, and an electronic switch. When used with the step-down converter, the kit is suitable for compatible loads such as Power Wheels ride-ons, lighting, and speakers.

  • Flexible Use: The step-down converter and battery adapter can also be used separately for other applications.

Frequently Asked Questions 

1. Can I convert 48V to 12V?

Yes. The MgcSTEM adjustable DC-DC step-down converter supports an input voltage of 11–70V DC and an adjustable output voltage of 3.3–24V DC. Set the output voltage according to your device's requirements.

2. Can this converter increase voltage?

No. This is a step-down converter only. The output voltage must be at least 2V lower than the input voltage.

3. Can I use a DeWalt 20V battery?

Yes, with a compatible DeWalt battery adapter. Before purchasing, check the supported battery voltage range and output specifications of the selected model.

4. Can the adapter's 12V output power any 12V device?

No. The device must also stay within the rated output current and power limits. For example, the dedicated 12V output port on the LVP-30-12V battery adapter has a maximum output current of 2.5A.
