AC power socket (AC)
When the battery uses direct current (DC).
When you buy a new dryer, it is important to know the voltage value at the outlet of your dryer.
Some dryers require more or less voltage than others.
If the socket you are using is not strong enough to support the dryer you are using, you may fuse and damage the dryer, socket or even home electrical settings.
You can combine the multimeter with three-and four-prong outlets.
