Do I need an adapter from Switzerland to Papua New Guinea?
Last reviewed · sourced from IEC TC 23 and national electricity standards
Your answer: Switzerland → Papua New Guinea
Plug adapter
Adapter required
Papua New Guinea uses Type I; your Switzerland plug (Type C, J) doesn't fit. Pack a Type I adapter — or a universal one if you travel often.
Voltage converter
Not needed
Both countries are on the same high-voltage standard (230V in Switzerland, 240V in Papua New Guinea). Your devices work as-is.

What this means for your trip
Going from Switzerland to Papua New Guinea you'll need a plug adapter, but voltage is identical on both sides, so that's one less thing to worry about.
Papua New Guinea uses Type I outlets; Switzerland uses Type C/J. The shapes are incompatible, so every plug you bring needs a Type I adapter to reach the socket. The cheapest option is a simple shape-only adapter for that one country; if you travel often, a universal adapter (fits every country) pays for itself in a single trip.
Voltage is the same on both ends (230V vs 240V, 50Hz vs 50Hz), so every charger that works at home works in Papua New Guinea without modification. No voltage converter, no hunting for "100-240V" on the brick.
Frequently asked
Do I need a travel adapter for Papua New Guinea from Switzerland?
Yes. Papua New Guinea uses Type I outlets, which don't accept Switzerland's Type C/J plugs. Pack a Type I adapter — or a universal one if you travel often.
What type of plug does Papua New Guinea use?
Papua New Guinea uses Type I outlets at 240V, 50Hz. Two flat angled pins (and sometimes a vertical grounding pin). Australia, New Zealand, China, Argentina.
What's the voltage in Papua New Guinea?
Papua New Guinea runs on 240V at 50Hz. That's on the high-voltage standard, higher than Switzerland's 230V supply. Most modern phones, laptops, tablets, and camera chargers are dual-voltage (check for "100-240V" on the brick) and work on either. Single-voltage devices like hair dryers, curling irons, and travel kettles will not — bring a dual-voltage travel version or a voltage converter.
Are Switzerland chargers dual-voltage?
Most — but not all. Check the charger brick for a line that reads something like "INPUT: 100-240V, 50/60Hz." If you see that, the charger works on either voltage standard and you only need a plug adapter. If it lists just "120V" (or just "230V"), it's single-voltage and can't be plugged straight into the other side without a voltage converter.
