What Is an 18V Compact Heat Gun?

An 18V compact heat gun (sometimes called hot air gun) is a cordless heat tool that runs off an 18 volt battery system. It combines portability (no cord or extension needed) with enough heat output to do many common jobs. “Compact” usually implies a smaller body, lighter weight, or more efficient design so you can use it in tighter spaces or for extended tasks without fatigue.

These tools bridge the gap between light duty “heat guns for crafts” and heavier mains electric heat guns.
