The 12V to 13.8V DCDC Boost Converter takes input in the 9V to 13V range and delivers a regulated 13.8V output at up to 4A. It is designed to provide a higher, stable voltage for devices that require 13.8V from a lower voltage source. Key benefits Delivers a stable 13.8V output from a 9V–13V input Maximum output current up to 4A Enables 13.8V equipment to run from common 12V automotive or other low voltage sources Helps minimize voltage sag when operating devices that demand a higher rail voltage Key attributes Functionality: DCDC boost converter that converts 9V–13V input to 13.8V output, with up to 4A of current Compatibility: Suitable for use with 12V systems and other 9V–13V sources that require a 13.8V supply Size and material: Not specified in the provided specifications Performance: Provides a regulated 13.8V output suitable for loads up to 4A Applications Powering 13.8V equipment from a 12V automotive supply or other 9V–13V sources, such as amateur radios, CCTV cameras, or mobile networking devices Supplying a 13.8V rail in offgrid or mobile setups where input voltage may fall within 9V–13V Providing a stable 13.8V supply for hobbyist electronics, test benches, or small 13.8V payloads that require reliable voltage boost Notes Size and enclosure material are not specified in the provided information; refer to product listing for physical dimensions and housing details No additional features beyond the stated input range, output voltage, and maximum current are described in the given specifications
