12V Peltier Cooling & Heating Module with 4 Modes & One-Button Control

A 12V semiconductor (Peltier) module that cools on demand with four clearly separated modes and one-button control — built to be installed into cooling vests, air-conditioned clothing, and DIY cooling gear.

4 Modes, One ButtonLong-press to power on or off, single-press to cycle through Energy Saving, High, Medium, and Low. A colored LED shows the active mode at a glance.
Cooling & Heating in One ModuleThe same module supports cooling for hot environments and low-level heating for cold-weather use, giving you one unit for year-round workwear.
Built-in Energy-Saving CycleIn Energy Saving mode the module cools for 10 minutes, pauses for 2 minutes, and keeps the fan running during the pause — reducing power draw while maintaining airflow.
Stainless-Steel Cooling SurfaceThe cooling side mounts against the garment while a high-speed fan on the other side continuously expels heat, keeping cooling effective during extended wear.

How It Works

This module uses a Peltier (thermoelectric) element: one side drops in temperature while the other side heats up. An integrated high-speed fan cools the hot side, so heat is pushed away from your body instead of building up inside the garment.

Power it with any 12V DC source (battery pack or adapter), mount the cooling plate inside your vest or garment, and you are ready to go.

Where It Fits

  • Cooling vests for outdoor work
  • Air-conditioned clothing and DIY cooling gear
  • Hot workshops, warehouses, and field work

Important Notes

  • Requires a 12V DC power source (battery pack or adapter, not included).
  • Cooling temperatures are no-load values measured at 77°F (25°C) ambient; actual performance varies with installation, airflow, and ambient conditions. Individual units may vary within ±9°F (±5°C).

Frequently Asked Questions

How do I switch between cooling modes?

Long-press the button to turn the module on or off. While on, single-press the button to cycle through Energy Saving, High, Medium, and Low. The LED color shows the current mode.

What does Energy Saving mode do?

Energy Saving mode cools for 10 minutes, then pauses cooling for 2 minutes while the fan keeps running. The cycle repeats automatically, lowering power consumption during light-duty use.

What power source does it need?

A 12V DC source such as a battery pack or adapter. The package includes the module and white box packaging; the power source is not included.

Why is the cooling temperature different from the specification?

The listed temperatures are no-load values measured at 77°F (25°C) ambient. Real-world temperature depends on how the module is installed, airflow, and ambient heat, and each unit may vary within ±9°F (±5°C).
