This 12V to 13.8V DCDC Boost Converter takes a 9V to 13V input and delivers a steady 13.8V output at up to 5A. It is designed to provide a constant voltage supply for devices that require a regulated 13.8V from a 12V system, even as input conditions vary. Key Benefits Constant 13.8V output: Maintains a stable voltage for equipment that needs a fixed 13.8V supply, helping to protect performance and consistency. current capability: Intended to supply up to 5A continuous output, making it suitable for mid‑range 13.8V‑rated devices. Wide 9V–13V input range: Compatible with common 12V sources, such as automotive, battery, and other 12V systems, allowing operation from varied input levels. Easy integration into 12V systems: A practical power solution for converting fluctuating input to a reliable 13.8V rail in vehicles, boats, RVs, and off‑grid setups. Key Attributes Functionality: DC‑DC boost converter that steps up from 9V–13V input to a constant 13.8V output with a maximum current of 5A. Compatibility: Designed for devices that require a 13.8V supply and for use with 9–13V input sources, enabling operation from standard 12V systems. Size and form factor: Built as a compact boost converter suitable for installation alongside other 12V electronics. Performance: Delivers stable 13.8V output at currents up to 5A, preserving a reliable power rail for connected equipment. Use Cases Automotive and mobile electronics: Power 13.8V devices such as amateur radios, CB radios, or other 13.8V‑rated equipment from a car's 12V electrical system, even when battery voltage fluctuates. Off‑grid and marine installations: Supply a steady 13.8V rail to instrumentation, CCTV cameras, or other 13.8V devices from a 12V battery bank on boats, RVs, or solar setups. Desktop or lab applications powered from a 12V source: Maintain a constant 13.8V supply for equipment that requires a fixed voltage, using standard 12V inputs.
