Cambodia is a magical destination, but its electrical infrastructure can be a bit of a jigsaw puzzle for first-time visitors. Unlike Singapore, which strictly adheres to a single plug standard, Cambodia utilizes a mix of different electrical sockets depending on the age of the building, the region, and the type of accommodation. 

To help you avoid any mid-trip charging crises, here is everything you need to know about the Cambodia power plug system, voltage compatibility, and practical charging tips for your 2026 adventure.

Cambodia uses a mix of three different types, largely because of its history of French colonial influence alongside more recent Chinese and American-style imports. Here's what you'll typically encounter:

The flat two-pin plug commonly used in the US, Canada, and Japan. You'll see this a lot in older guesthouses, budget accommodations, and local extension cords.

The round two-pin "Europlug," standard across most of Europe. This is one of the most widely used types in Cambodia and fits into the same sockets as Type A in many outlets.

The three-pin rectangular plug used in the UK, Singapore, Malaysia, and Hong Kong. This is the one most relevant to Singaporean travellers, and it's increasingly common in mid-range to high-end hotels, malls, and newer buildings.

Because of this mix, many hotels, especially those catering to international tourists, install "universal" sockets designed to accept multiple plug types at once, so you can often plug in Type A, C, or G devices into the same outlet without needing an adapter at all.

Cambodia runs on a standard voltage of 230 V at a frequency of 50 Hz. This is essentially identical to Singapore's own electrical standard, which also operates at 230 V and 50 Hz. 

This means, if you're travelling from Singapore, your devices are already calibrated for Cambodia's power supply. You won't need to worry about voltage mismatches the way travellers from the US or Canada (which run on 120 V) typically do. 

That said, always glance at the label on your charger or power brick just to be safe, especially for older appliances like hair straighteners or electric shavers that may not be dual voltage. Look for text like "INPUT: 100–240V, 50/60Hz" which confirms the device can handle a wide voltage range safely, no converter needed.

For most Singapore travellers, the answer is probably not, but it's smart to bring one anyway.

Since Singapore and Cambodia share the same voltage (230 V) and frequency (50 Hz), you won't need a voltage converter. Your electronics won't be at risk of damage from an electrical mismatch, and your regular chargers will work just fine once plugged in.

As for plug adapters, it really depends on where you're staying. Many hotels and serviced apartments in Phnom Penh, Siem Reap, and Sihanoukville now install universal sockets that accommodate Type G plugs directly, meaning your Singapore charger will slot right in. 

However, if you're staying somewhere older, more budget-friendly, or off the beaten path, you might run into Type A or C sockets that won't accept your Type G plug without help.

The safest move is to pack a compact universal travel adapter. It's inexpensive, takes up almost no space in your bag, and covers you regardless of what socket you end up facing. Think of it as cheap insurance against a dead phone on day one of your trip.

Finding electrical accessories in Cambodia is relatively straightforward. They're easy to find once you land.

Phnom Penh and Siem Reap international airports both have shops selling adapters, though prices here tend to be higher, best treated as a backup option rather than your main plan.

Found in nearly every town, these are your quickest bet for a basic adapter, often at a lower price than what you'd pay at the airport.

Larger supermarkets in Phnom Penh like AEON Mall and Siem Reap often stock basic travel adapters and charging accessories.

Central Market (Phsar Thmey) in Phnom Penh and the Old Market in Siem Reap both have stalls selling cheap adapters, though quality can vary, so give it a quick test before relying on it.

Many hotels keep a small stash of adapters to lend to guests, so it's always worth asking before you go out and buy one.

To wrap up your electrical preparation, keep these practical, battle-tested traveller tips in mind:

If you're booking through Traveloka, hotel listings often include photos of the room, which can give you a hint of what socket type to expect. When in doubt, just message the property directly.

If you're bringing multiple devices, consider a travel adapter with multiple USB ports built in, useful for charging a phone, camera, and power bank simultaneously. 

Power banks are worth packing if you're heading to more rural areas like Koh Rong or remote parts of Mondulkiri, where power access can be less consistent. Beside that, power outages happen, particularly during the rainy season (roughly May to October).  

Check your hair dryers or straighteners before plugging in. Even though Singapore and Cambodia share the same voltage, it's just good practice with unfamiliar outlets. 

Choosing accommodation with reliable, modern electrical outlets makes a real difference to your trip. You can browse and book hotels across Cambodia's most popular destinations with confidence. 

Boutique hotels and international chains along the riverside offer modern rooms with universal sockets and USB charging ports built in. 

Hotel recommendations: Raffles Hotel Le Royal, Rosewood Phnom Penh, Hyatt Regency Phnom Penh, NagaWorld Hotel & Entertainment Complex, and Baitong Hotel & Resort.  

Stay close to Angkor Wat with a range of options from cozy guesthouses to resort-style hotels, many of which cater specifically to international travellers with adapter-friendly outlets. 

Hotel recommendations: Park Hyatt Siem Reap, Raffles Grand Hotel d'Angkor, Jaya House River Park Hotel, Tara Angkor Hotel, and Golden Temple Residence.

Beachfront resorts here are a great choice if you're looking to unwind after temple-hopping, though it's worth checking amenities carefully if you're headed to smaller islands with less consistent power supply. 

Hotel recommendations: Sokha Beach Resort, Independence Hotel by Dara, The Royal Sands Koh Rong, and Long Set Resort.
