Convert your vehicle's 12V battery into a stable 24V–28V DC supply with this waterproof car power module. Designed for applications that require a higher DC voltage from a standard 12V automotive system, this booster delivers up to 1A of output current and is built for use invehicle and other mobile environments. Key benefits Solve incompatible voltage problems: power 24V and 28V devices directly from a 12V car system without rewiring or separate batteries. Compact and robust: a small, waterproof booster module that can be mounted where space is limited and exposed to moisture. Clear capacity limits: supplies up to 1A at the boosted voltage, so you can match devices to the converter's rated output. Main features and attributes Functionality: DCtoDC boost converter that takes a 12V input and provides a 24V to 28V output. Output current: rated up to 1A at the boosted voltage. Compatibility: intended for use with 12V automotive electrical systems to power devices that require 24V or 28V DC within the 1A current limit. Environmental protection: waterproof construction for reliable operation in damp or outdoor automotive locations. Performance: designed to maintain a higher DC output from a 12V source so accessories and electronics rated for 24V–28V can operate from a car battery. Practical use cases Power 24V LED lighting, small controllers, or instrumentation in a vehicle that normally runs on 12V battery power. Run 24V sensors, communication modules, or monitoring equipment from a car or marine 12V supply when a separate 24V source is not available. Supply small 28V devices in mobile installations where waterproofing and compact size are needed and the device current draw stays at or below 1A. Installation and selection tips Verify the target device's voltage and current requirements: this module boosts to 24V–28V and is limited to 1A output. Mount in a dry or protected area when possible; the module is waterproof but installing it where wiring is secure and strainrelieved improves longevity. Use appropriate wiring and fusing in the input circuit to match your vehicle's electrical system and local safety practices. This 12V to 28V (12V to 24V) 1A car power module is a focused solution for powering highervoltage accessories from a 12V automotive source when output needs are within the 1A rating and a waterproof, compact converter is required.
