More than lighting a cigarette, you use the cigarette lighter socket in your vehicle as a source of power for your electronic gadgets. If you’re absolutely certain that you’ll never want to use your cigarette lighter as a cigarette lighter, or even as a 12-volt socket, then yes, it is possible to tear it out and replace it with another accessory like a dedicated USB port.

The easiest way to replace a cigarette lighter with USB is to just toss the lighter portion and plug in a low profile 12V USB adapter. Some 12V USB chargers are big and bulky, but there are a number of options that fit more or less flush with the dash and come in a variety of colors to better match the trim. This option will leave your cigarette lighter in place as a 12V accessory socket, just in case you ever want to plug in a tire pump or anything else that can’t be powered by USB. Done correctly, it will also result in a clean installation that gives the impression that you have ditched your cigarette lighter in favor of a USB port.
