What Plug Type Does Oman Use?
Oman primarily uses Type G sockets — the same three-rectangular-pin, triangular-shaped plug used across the United Kingdom. You’ll find Type G outlets in nearly every hotel, airport terminal, shopping mall, and private home in the country. Older buildings occasionally have Type C sockets (the two-round-pin “Europlug”), but Type G is the national standard, so it’s the one worth packing for.
If you’re arriving via Muscat International Airport ahead of exploring destinations like Muscat’s top attractions, it’s worth having your adapter ready in your carry-on rather than packed in checked luggage.
Voltage and Frequency in Oman
Oman’s electrical supply runs at 230–240 volts, 50 Hz. This matters more than the plug shape, because an adapter only changes the physical connector — it does nothing to change voltage. Plugging a single-voltage 110V device into a 240V outlet without a converter can permanently damage it.
| Home Region | Typical Voltage | Plug Type at Home | Adapter Needed? | Voltage Converter Needed? |
|---|---|---|---|---|
| UK, Ireland | 230–240V | Type G | No | No |
| EU (most countries) | 220–230V | Type C/E/F | Yes (shape only) | No |
| Australia, New Zealand | 230V | Type I | Yes (shape only) | No |
| USA, Canada | 110–120V | Type A/B | Yes | Yes, for non-dual-voltage devices |
| Most of Asia, Gulf states | 220–240V | Varies | Sometimes | No |
Do You Actually Need a Voltage Converter?
Dual-voltage devices
Most modern electronics — laptops, phone chargers, camera batteries, tablets, and electric toothbrushes — are built to handle a wide voltage range. If the label shows “100–240V,” you only need a plug adapter, not a converter.
Single-voltage devices
Older appliances, and many hair dryers or straighteners made specifically for the US market, often run on 110–120V only. These need a dedicated voltage converter in Oman, since 230–240V will otherwise overheat or damage the device. According to the international reference on Type G plug standards, this configuration has been used across former British territories, including Oman, since the mid-20th century.
Packing Checklist by Traveler Type
-
Travelers from the UK
Your plugs fit Omani sockets directly. In most cases, no adapter or converter is needed at all. -
Travelers from the EU
Bring a simple Type C/E/F-to-G adapter. Since voltage is close to Oman’s standard, a converter usually isn’t necessary. -
Travelers from the US or Canada
Bring a Type A/B-to-G adapter, and check each device individually. Dual-voltage electronics only need the adapter; single-voltage appliances need a converter too. -
Travelers from Australia or New Zealand
Bring a Type I-to-G adapter. Voltage is already compatible, so no converter is required.
Where to Buy Adapters Before or During Your Trip
-
✓
Buy a universal travel adapter before departure — it’s usually cheaper and gives you more time to test it at home. -
✓
Muscat International Airport has electronics kiosks selling Type G adapters if you forget one. -
✓
Most hotels can lend an adapter at the front desk in a pinch, though supply is limited. -
✓
Pack a multi-port adapter with USB outlets if you’re traveling with multiple devices — useful during longer road trips, like heading out to Wadi Darbat where charging stops are fewer.
