This kit includes all the parts needed to build a 12V to 5V, 4A power converter that can run a Raspberry Pi from a 12V source, such as a car battery. It’s compatible with both the Raspberry Pi 3 and 4, with the appropriate cable. It has all of the parts for the converter, input and output cables and a box to put it in.<\/p>\n

For more details, see the post “Run the Raspberry Pi on 12V.<\/a>”<\/p>\n

This converter is designed for applications where a linear regulator\u2014typically only around 40% efficient with this voltage difference\u2014won’t cut it. Battery-powered devices are the main use case, and the design specifically targets the Raspberry Pi 4B. With up to 91% efficiency, it can run 5V devices significantly longer on battery power. Soldering is required.<\/p>\n
