The 20A DC Power Converter is an automotive boost regulator that converts a 12V24V DC input to higher voltage outputs for devices that require more power from a vehicle or mobile power source. It is designed to support a range of common input and output voltages in a single compact module. Key benefits Flexible output options: provides 19V, 24V, 28V, or 48V output to match a variety of devices from a 12V24V source. current capability: rated to deliver up to 20A at the chosen output, suitable for demanding loads. Automotive ready: specifically designed for 12V24V electrical systems found in cars, trucks, vans, and RVs. Compact, single unit: comes as 1 piece per package, minimizing space and installation complexity in mobile environments. Simple voltage enhancement: enables powering devices that require higher voltage than the vehicle battery can supply directly, reducing the need for multiple adapters or power sources. Key attributes Functionality: DC boost regulator that converts 12V24V input to higher voltage outputs (19V, 24V, 28V, 48V). Compatibility: suitable for automotive electrical systems operating within 12V24V input. Output options: 19V, 24V, 28V, and 48V selectable outputs. Input range: 12V24V DC. Current rating: up to 20A maximum output current. Packaging: 1 piece per package. Size and material: not specified in the listing. Performance notes: delivers higher voltage outputs from a 12V24V source as a boost regulator; exact efficiency and thermal performance are not detailed in the listing. Use cases Power a laptop or other 19V devices from a vehicle battery while on the road, enabling work or entertainment without AC power. Run 24V equipment or tools from a 12V24V vehicle system, useful for mobile installations or fieldwork. Provide 28V or 48V supply for compatible portable devices or test equipment directly from a car, truck, or RV power source.
