DCDC boost converter voltage stabilizer power module designed for 12V input with higher voltage outputs. The unit can boost to 19V, 24V, 28V, or 36V and supports current in the range of 3A to 20A. This listing is for one unit and is specified as 8A TO 28V in the product title. Key benefits Enable higher voltage devices to run from a 12V source by boosting to 19V, 24V, 28V or 36V. Provides voltage stabilization to help protect sensitive electronics from supply variation during load changes. Flexible current capability suitable for a range of loads, including mid power applications. Compact power module design for easy integration into enclosures, control boards, or DIY projects. Reduces the need for multiple dedicated power adapters by using a common 12V source. Key attributes Functionality: DCDC boost converter with voltage stabilization Input: 12V DC (nominal) Output voltages: selectable 19V, 24V, 28V, and 36V Output current: 3A to 20A (this unit is specified as 8A TO 28V in the listing) Package: 1 piece per Compatibility: suitable for systems that require higher voltage from a 12V source such as portable power, robotics, and compatible electronics Form factor: compact power module designed for convenient installation and wiring Performance: designed to boost from 12V input to stable higher voltage outputs with adjustable current capability up to the specified range Applications and use cases Laptop and portable device power from a 12V battery or vehicle power system by selecting 19V or 24V output to match device requirements. Robotics and motorized equipment where 28V or 36V supply is needed but only a 12V source is available, enabling higher voltage operation from a common battery. Solar or off grid setups requiring higher voltage to feed compatible controllers or instruments, improving system flexibility and reducing the number of adapters. Usage notes Ensure correct connection of input and output terminals and respect polarity. Verify the device voltage requirement and select the corresponding output option (19V, 24V, 28V, or 36V) to match the load. Adequate heat dissipation is recommended for sustained operation at higher current levels. This description reflects the specifications in the product title including the 8A TO 28V variant and the 12V to 36V boost capability.
