This 12V to 19V 4A DC power converter provides a 19V DC output from a 12V DC source with a maximum current of 4A. It is designed to power devices that require a 19V input from a 12V supply, making it suitable for use in vehicles, offgrid setups, and other environments where only a 12V source is available. Key benefits Enables operation of 19V devices from a 12V power source, expanding where you can power equipment. Handles up to 4A of output current, supporting devices that require up to 19V and up to 76W of power. Enables flexible power solutions in vehicles, workshops, and portable power arrangements where AC outlets are unavailable. Simplifies setups by supplying a single 19V source from commonly available 12V supplies, reducing the need for multiple adapters. Supports onthego usage, improving uptime for devices that normally rely on wall outlets. Key attributes Input voltage: 12V DC Output voltage: 19V DC Maximum output current: 4A Maximum output power: 76W (19V x 4A) Compatibility: suitable for devices that require 19V input with current demand up to 4A Size and material: dimensions and enclosure material are not specified Notes: description reflects the stated specifications of input, output, and current; no additional features are specified Use cases Powering a 19V laptop or 19V peripheral from a 12V vehicle battery or 12V portable power source during travel or field service. Providing a 19V supply for demo equipment, monitors, or other 19V devices at remote locations where only 12V power is available. Supplying backup power for 19V devices using a 12V battery pack or solar charging setup, enabling continued operation away from standard AC outlets.
