    How To Switch Voltage on a Hair Dryer

    Published/Updated: Jul 9, 2025 · Erica Ho · Under a minute read

    It's a little embarrassing on how much we've written on the topic, but the truth is, if you don't have a little graveyard of hair dryers buried in your past, *clearly* you're not traveling correctly.

    There are a few easy ways to mitigate blowing hair dryers out abroad: 1) blow drying on low, 2) traveling with a voltage converter, or 3) buying a dual voltage hairdryer and learning how to switch the voltage like a sane, smart human being. The last option being not the only easiest, but, apparently, the least understood 😂

    (Trust me, we've owned a dual-voltage hairdryer for decades, and it is only now that we figured it out.)

    Here's how to do it: Take a coin, find the little button that points to 125 or 250-the voltage indicator-and use the coin to turn the knob slot.
