Marshall Islands to Papua New Guinea: Complete Plug & Adapter Guide (2026) Adapter Needed

Whether it's a business trip or a vacation, traveling from Marshall Islands to Papua New Guinea requires a quick check on power compatibility. The last thing you want is to arrive and discover your charger doesn't fit the outlets.

There's no plug compatibility between Marshall Islands and Papua New Guinea. Marshall Islands devices use Type A/B connectors, while Papua New Guinea sockets are Type I. An adapter is a must-have for this destination.

The electrical standards differ significantly: Marshall Islands operates at 120V/60Hz and Papua New Guinea at 240V/50Hz. For single-voltage appliances (hair straighteners, kettles, etc.), this mismatch could damage your device or even be a safety hazard. Always verify your device's voltage rating before plugging in.

When packing for Papua New Guinea, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
