Do You Need an Adapter?

Australia/New Zealand - Type I - Need Type C/K adapter
India/South Africa - Various types - Need Type C/K adapter

Voltage Compatibility

230V vs 110V Devices:

✅ Modern electronics (phones, laptops, cameras, tablets) - Usually dual voltage (110-240V). Check device's power adapter label. Only need plug adapter, not voltage converter.

⚠️ Hair dryers, curling irons, electric razors - Often single voltage (110V for US devices). Will need voltage converter OR purchase dual-voltage versions. Using 110V device in 230V outlet will damage it.

Check your device label for:
Input: 100-240V~50/60Hz = Dual voltage, works fine with just plug adapter
Input: 120V~60Hz = Single voltage, needs voltage converter

Practical Tips

Buy adapters before departure - While available at Copenhagen Airport and electronics stores, they're more expensive than purchasing at home
Universal travel adapter - Best investment for multi-country trips, includes USB ports for charging multiple devices
USB charging - Many modern hotels have USB outlets built into room sockets, eliminating adapter need for phones
Power strips - Bring one from home to multiply your charging ports from single adapter
Hotel amenities - Most Copenhagen hotels provide hairdryers (230V), so leave yours home if it's single voltage
Voltage converters - Heavy and expensive; easier to buy dual-voltage appliances or use hotel amenities
Purchase locally - If forgot adapter, buy at 7-Eleven, Føtex, or Magasin department store (DKK 50-100)
