Voltage converter or adapter not working abroad

Symptoms

• Device won't turn on when plugged in abroad
• Device turns on briefly then shuts off or smells odd
• Adapter gets hot during use
• Device works with a plug adapter at home but not overseas

Likely causes

• CommonUsing a plug shape adapter instead of an actual voltage converterA plug adapter only changes the shape of the plug, not the voltage, which can be 110–120V or 220–240V depending on the country.
• CommonDevice isn't dual-voltage and isn't rated for the local voltageCheck the device's label; if it says a specific single voltage only, it needs a true converter, not just an adapter.
• PossibleConverter is undersized for the device's wattageHigh-wattage devices like hair dryers need a converter rated well above their wattage.
• Less commonLocal voltage or frequency differs enough to affect sensitive electronicsSome devices with motors or clocks are sensitive to 50Hz vs 60Hz differences.

What to do

1. Check the device's label or manual for its voltage rating; look for text like '100–240V' which means it's already dual-voltage.
2. If it lists only one voltage, you need an actual voltage converter or transformer, not just a plug shape adapter.
3. Never plug a single-voltage 120V device directly into a 220–240V outlet with only a plug adapter, since this can destroy it and pose a fire risk.
4. Match the converter's wattage rating to well above what the device draws, especially for heat-based devices like hair dryers or irons.
5. If a device smells odd, smokes, or shuts off immediately after plugging in, unplug it right away and don't reuse it until inspected.

When to call a pro

If a device has already been damaged by a voltage mismatch, have it inspected by a repair shop before attempting to use it again.
