Tecnolove DC Battery Module for Car Refrigerator, 173Wh Dedicated Power Extension Module with Plug-In Design for 12V/24V Vehicle Cooling Systems

【Purpose-Built DC Power Extension for Car Refrigerators】Engineered as a dedicated DC power extension module, this unit is designed exclusively for compatible car refrigerators and integrates directly with 12V/24V vehicle cooling systems. The 173Wh internal battery supports continued cooling performance during engine-off periods, helping maintain stable internal temperatures under standard ambient conditions (77℉ / 25℃).

【Supports Cooling Continuity When the Vehicle Is Turned Off】This accessory battery module is intended to support cooling continuity when the vehicle engine is not running. It can be manually activated during stops or parking to help maintain refrigerator operation, reducing temperature fluctuations and helping protect stored contents without drawing power from the vehicle’s starter battery.

【Convenient Recharging Designed for the Module Itself】To prepare the module for reuse, the internal battery can be replenished through compatible charging sources, including vehicle DC input during driving or supported external charging equipment. These options are provided solely to maintain the module’s internal battery for use with a car refrigerator and are not intended for powering other devices.

【Intelligent Vehicle Battery Protection】A built-in voltage monitoring system with adjustable input modes (Low / Medium / High) helps manage how the refrigerator draws power when connected through the vehicle’s DC port. This design supports responsible power use and helps protect the vehicle’s starter battery during extended stops or parking.

【Dedicated Connection for Clean Integration】The module features a dedicated 6-pin DC output port for a secure, single-cable connection to compatible car refrigerators. This non-universal interface is designed specifically for refrigeration equipment and does not support general-purpose electronic devices, helping ensure a stable and purpose-built power connection.
