  • Product Description:

    Keep it cool with a Peltier module Thermoelectric Cooler . These unique electronic components can generate a temperature differential when powered. That is to say, apply 12V to the red (positive) and black (negative) wires and one side will get cold while the other side gets hot. For best results, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). A fan and/or heatsink is ideal. This module is a 12V module, and is rated for ~72W max (up to 14V/6A) but when used with a regulated 12V output they don't draw more than 5A so we suggest our 12V/5A power adapter for use.
