12V to 13.8V DCDC Boost Converter Module (9V13V Input, 4A Output), Boost Voltage Power Converter The 12V to 13.8V DCDC Boost Converter Module provides a dedicated boost from a 9V to 13V input to a stable 13.8V output with a current capability up to 4A. It is designed to support 12V systems that require a higher charging or supply voltage, delivering a straightforward solution for increased voltage where needed. Key benefits Reliable 13.8V output from 9V–13V input to support 12V systems and devices that require higher voltage. current capability up to 4A, enabling power delivery to midscale loads without a separate charger. Simple integration as a compact DCDC boost converter module suitable for hobbyist and professional projects. A focused solution for maintaining proper voltage in automotive and 12V battery applications where input can vary. Keeps 12V electronics operating at the required 13.8V level, reducing voltagerelated performance issues. Key attributes Functionality: DCDC boost converter module that converts 9V–13V input up to 13.8V output with a maximum of 4A. Compatibility: Designed for use with 9V–13V input sources and 12V systems that need a boosted 13.8V supply. Size: Compact module form factor suitable for compact installations and DIY projects. Material: Built as a standard DCDC boost module using conventional electronic components for reliable operation. Performance: Delivers up to 4A output at 13.8V, enabling use with midpower 12V devices and charging applications. Use cases and applications Automotive and vehicle systems: Provide a stable 13.8V supply in cars, trucks, RVs, or boats where the electrical system fluctuates, helping maintain battery charging and powering 13.8Vdependent devices. Battery charging and maintenance: Use in 12V leadacid or related battery setups to sustain a 13.8V charging level when the source voltage dips below that value. DIY electronics and hobby projects: Power 12V devices or modules that require a 13.8V supply from a lowervoltage source, enabling experiments and deployments in a compact package. Notes Input range: 9V to 13V Output: up to 13.8V at a maximum current of 4A This module is a dedicated boost solution and does not alter the fundamental 9–13V input constraint or extend beyond the specified 4A output limit. This product provides a clear, practical approach to obtaining 13.8V from a 9–13V source, supporting 12V systems with a need for boosted voltage in everyday automotive, solar, and DIY applications.
