Where Is My Device's Voltage Label?

Look on the underside of the device, on the power plug itself, or on the charger/power brick — find the line that starts with "INPUT".

V = volts (the most important number for safety). Hz = frequency. A and W = current and power. The ~ symbol means AC (normal household power).

"INPUT 100–240V~ 50/60Hz" means dual voltage; a single value like "120V" means single voltage.

If you can't find or read the label, don't plug in until you've confirmed it.
