Making a powerful 12V power bank with a cigarette lighter socket

Hello, dear readers and homemade products!
Almost every motorist has various devices and devices powered by a cigarette lighter (air compressor, vacuum cleaner and others). Sometimes it becomes necessary to use these devices away from the car, at home, or without connecting to a standard cigarette lighter.
In this article, the author of the YouTube channel “KJDOT” will tell you how he made a portable rechargeable power supply unit (powerbank) with a cigarette lighter socket.
