## Summary description

Retoo car DC-DC converter designed to reduce and stabilize vehicle electrical voltage with an input range of 18–36 V. Functions as a power converter/voltage reducer for automotive applications, enabling safe supply of lower-voltage electronics, battery charging or auxiliary devices. Suitable for trucks, buses and vehicles with higher nominal system voltages.

## Long description

The Retoo Car DC-DC Converter is a voltage reducer and power converter designed for vehicles with higher nominal electrical systems. It accepts a wide input voltage range of 18–36 V and delivers a stabilized lower output to power or charge 12 V electronics and auxiliary devices. The unit is intended for automotive use where on-board voltage can exceed standard 12 V, providing a reliable method to supply equipment that requires reduced and regulated voltage.
Advantages
This converter provides stable voltage reduction across a broad input range, compatible with trucks, buses and other vehicles with elevated system voltage. It is compact and intended for in-vehicle installation, reducing the need for manual adjustments while protecting connected devices from overvoltage. The design focuses on practical electrical conversion, offering consistent output under varying input conditions typical in commercial and heavy-duty vehicles.
Suitable for
Powering 12 V electronics in trucks, buses and commercial vehicles
Charging auxiliary 12 V batteries from higher-voltage vehicle systems
Supplying accessories such as radios, lights, sensors and control modules
When it may not be suitable
This converter is not intended for use as a general household power supply or as a replacement for a full inverter to provide AC mains power. It may not be appropriate for vehicles with nominal system voltages below the stated input range or for devices that require precise multi-rail outputs unless those requirements are explicitly supported.
Key specifications
Input voltage range: 18–36 V DC
Function: DC-DC voltage reduction and power conversion for automotive applications
Intended output: stabilized lower-voltage DC suitable for 12 V devices (confirm exact output voltage and current rating with technical sheet)
Application environment: in-vehicle use, compatible with heavy-duty and commercial vehicles
How to use
Install the converter in a dry, ventilated location within the vehicle, close to the power source and the devices to be powered. Connect the input to the vehicle’s higher-voltage supply following polarity and secure connections to prevent vibration-related loosening. Connect the output to the 12 V load or battery, verifying that the converter’s output specifications match the requirements of connected devices. After wiring, test the installation with the vehicle powered to confirm stable output before leaving devices connected for extended periods.
What to consider before purchase
Verify that the vehicle’s nominal system voltage consistently falls within the 18–36 V input range
Confirm the converter’s output voltage and current capabilities meet the needs of the devices to be powered
Ensure suitable mounting space and ventilation in the intended installation area
Check compatibility with battery charging requirements if used to charge auxiliary batteries
Usage recommendations
For reliable operation, use appropriate fuses on both input and output lines, maintain secure mechanical mounting to reduce stress from vibration, and consult the device’s technical documentation for detailed electrical limits and thermal considerations.
