Do I Need a Voltage Converter for Europe?
For most travelers, the answer is no: you need a plug adapter, not a voltage converter. But it depends on each device, and getting it wrong with a hair dryer can ruin the dryer or worse. Here's how to tell.
The difference
- A plug adapter changes the shape of the plug so it fits the wall socket. It doesn't change the electricity.
- A voltage converter changes the voltage. The US uses about 120 volts. Most of Europe uses about 230 volts.
Check the label
Look at the small print on the charger, power brick or device. You'll see an "Input" line.
- "Input: 100-240V" means the device is dual voltage. It works in Europe with just a plug adapter. Most phone chargers, laptop chargers, camera chargers and tablet chargers are like this.
- "Input: 120V" or "110-120V" means single voltage. Plugging it into 230V with just an adapter can damage it, or be dangerous.
Devices that are usually fine
- Phone, tablet and watch chargers
- Laptop chargers
- Camera battery chargers
- Electric toothbrush chargers, if the label says 100-240V
These all work with a plug adapter like the TESSAN European adapter, which also adds extra outlets and USB ports.
Devices that usually aren't
- Hair dryers, curling irons and straighteners made for the US are often 120V only. They also draw a lot of power.
- Some electric razors and older appliances.
For these, your choices are:
- Buy a dual-voltage travel version. Many travel hair dryers and straighteners have a voltage switch.
- Use the hotel's hair dryer. Many European hotels provide one.
- Use a proper voltage converter rated for the device's wattage. High-wattage heating appliances need a heavy-duty converter, and many small "travel converters" aren't up to it.
Two safety tips
- Never plug a high-power heating appliance into a small multi-outlet adapter. Check the adapter's rated watts and amps.
- If you're not sure, don't plug it in. Check the label first.
