Electricity and sockets
Plug types, voltage and frequency at a glance, followed by a comparison with your home country.
Sockets at the destination
In plain terms
Papua New Guinea uses Type I sockets. The recorded supply is 240 V at 50 Hz. Whether you need an adapter depends on the plug fitted to your device and the country you are travelling from.
An adapter must match both sides of the connection. If the device is earthed, the protective-earth path must remain intact. The quick comparisons below cover common home countries.
Protective earth
The recorded systems (Type I) normally include protective earth. For Class I equipment, the adapter must maintain earth continuity.
Useful on the road
The recorded supply for Papua New Guinea is 240 V at 50 Hz. The socket in a particular room, older building or transport facility can still differ, especially where several systems are in use.
The national data is consistent, but the condition of an individual socket cannot be judged from it. Avoid loose, cracked, scorched or wet outlets, and never force an adapter into place.
Unplug the device if the socket becomes hot, crackles, smells burnt, repeatedly trips a breaker or the lights fluctuate strongly. Let the accommodation or operator deal with the installation.
These examples use common label ranges. The rating printed on your own device is the one that counts.
100–240 V · 50/60 Hz
This range covers the recorded supply. You may still need a plug adapter.
100–240 V · 50/60 Hz
This range covers the recorded supply. You may still need a plug adapter.
220–240 V · 50 Hz
This range covers the recorded supply. You may still need a plug adapter.

The sources describe the systems commonly used in each destination. A particular building, ship or multi-standard outlet can still differ, so the actual socket and device label remain decisive.
