The 12V to 13.8V 3A DC power converter provides a regulated 13.8V DC output from a 12V input source, delivering up to 3A of current. It is designed for devices that require 13.8V from a 12V system, offering a straightforward solution for automotive, marine, RV, or lab applications. Key benefits Delivers a stable 13.8V DC output from a 12V supply to power devices that require 13.8V. Supports up to 3A maximum current, enabling mid‑range power needs from a common 12V source. Enables operation of 13.8V equipment without a dedicated 13.8V supply, simplifying installations and reducing cabling complexity. Provides a compact, purpose‑built solution for converting available 12V power into the voltage needed by compatible devices. Key attributes Functionality: DC power converter that steps up from 12V to 13.8V with regulated output. Output: 13.8V DC at up to 3A. Input: 12V DC input source. Compatibility: Suitable for devices designed to operate on 13.8V DC power. Size and material: Not specified in the provided information; details are not listed here. Applications and use cases Automotive use: Power or maintain 13.8V equipment in a vehicle from the 12V battery, such as radios, transceivers, or other onboard electronics. Lab or test bench: Provide a 13.8V supply for testing 13.8V devices when only a 12V source is available. Marine or RV setups: Run equipment that requires 13.8V from a 12V system on boats or motor homes, simplifying power management in confined spaces. Notes Ensure the device being powered is within the converter's 13.8V output and 3A current rating. Verify proper wiring polarity and secure electrical connections to maintain safe operation.
