Travel Adapter for Mexico: Do You Need One? (Cambodia → Mexico)Adapter Needed

If you're heading to Mexico from Cambodia, sorting out the power situation is one of the easiest pre-trip wins. Below you'll find the plug types, voltage, and frequency used in Mexico, whether you need an adapter, and which devices are safe to plug in.

Do you need a travel adapter for Mexico?

Good news: you generally don't need a plug adapter. Both Cambodia and Mexico use Type A outlets, so your existing plugs should fit Mexico's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

What plugs and sockets does Mexico use?

Mexico uses these power plug types: Type A: two flat parallel pins (ungrounded), the standard North American and Japanese plug; Type B: two flat pins plus a round grounding pin, common in North America. Outlets run at 127V and 60Hz. Since Cambodia also uses Type A, your plugs already match.

Voltage and frequency in Mexico

Mexico supplies 127V at 60Hz, which differs notably from the 230V used in Cambodia. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 230V-only device into a 127V outlet can overheat or destroy it. Check each device's label: if it reads "INPUT: 100-240V" it handles both and you only need a plug adapter; if it lists a single voltage, bring a voltage converter or leave it home.

Will your devices work in Mexico?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Mexico with just your existing plug, and no converter is required. The devices to watch are heat-based appliances: hair dryers, flat irons, and travel kettles are often single-voltage and can fail on Mexico's 127V supply. Many travelers simply buy a dual-voltage travel version or rely on the hotel's hair dryer.

What travel adapter should you buy for Mexico?

Because Cambodia and Mexico share Type A outlets, you don't need a special adapter for this trip. A universal travel adapter is still a smart, inexpensive backup if you plan to travel elsewhere, and the better ones add USB-C fast charging to free up your charger.

Tips for charging your devices in Mexico

Pack at least one adapter per traveler, and consider a small power strip from home, which turns a single Mexico outlet into several. Ordering online before you fly is almost always cheaper than airport kiosks.
