Travel Adapter Calculator
The Travel Adapter Calculator compares your home country against your destination country and tells you the exact adapter type to buy, or confirms you don't need one at all. Select both countries and click Calculate Adapter to run the comparison. It's built on real plug type data for every country, so you get a specific answer — Type G, Type C, Type I — not a generic "get a universal adapter" shrug. Worth a look: the power outlet compatibility checker.
Calculate Your Adapter
How the Travel Adapter Calculator Works
The calculator reads the standard plug type(s) used in your home country and compares them against your destination country's standard plug type(s). Where there's an overlap, your existing plug already fits the socket and no international plug adapter is needed. Where there's no overlap, it names the destination's plug type directly, so you know exactly which travel adapter to buy instead of a vague "check before you go." Also see the USB-C Charger Travel Compatibility Checker.
Types of Travel Adapters
Both of the two common adapter styles only change the pin arrangement — neither one converts voltage.
Single-Type Plug Adapters
A single-type adapter converts one plug shape to one socket shape and is usually the smallest, cheapest, most reliable option for a destination you visit often.
Universal Travel Adapters
A universal adapter (sometimes marketed as an all-region or worldwide travel adapter) reconfigures for several plug types from one unit, trading a little bulk for covering multiple countries on the same trip.
Plug Types by Region — Quick Reference
These groupings cover most destinations; run your specific route through the calculator above for a country-level answer, since a handful of countries within each region are exceptions.
| Region | Common plug type(s) |
|---|---|
| North America | Type A, Type B |
| Continental Europe | Type C, Type E, Type F |
| United Kingdom, Ireland, Hong Kong, Singapore, Malaysia | Type G |
| Australia, New Zealand, China | Type I |
| India, South Africa | Type D, Type M |
When a Country Uses Multiple Plug Types
Quite a few countries list two standard plug types rather than one, usually because an older standard is still wired into some buildings alongside a newer one. If your plug matches either, you're covered without an adapter; if it matches neither, buy for whichever of the two is more common in modern buildings and hotels — that's the safer default when you can't confirm the specific property in advance.

Grounded vs Ungrounded Adapters
Grounded (Earthed) Travel Adapters
If your device has a 3-pin grounded plug, use an adapter that preserves the earth connection rather than a basic 2-pin pass-through — some cheap adapters quietly drop the ground pin, which matters for higher-power appliances.
Ungrounded (Two-Pin) Adapters
If you're travelling from an ungrounded 2-pin standard into a grounded destination, most devices will still work through a standard adapter, since grounding is a safety addition rather than a requirement for the circuit to function.
Do I need a different adapter for every country I visit?
Only if the plug types differ. Many neighboring countries share the same plug type — most of continental Europe uses Type C/E/F together — so one adapter can cover an entire region. Run each destination through the calculator above rather than assuming; borders don't always match plug types.
What does it mean if a country uses more than one plug type?
Some countries standardized on one type but still have older sockets or hotel wiring using another, so both remain listed as in use. Your existing plug likely fits at least one of them; if it fits neither, get an adapter for the more common of the two — hotels and modern buildings default to it far more often than not.
Should I buy one universal adapter or type-specific ones?
A universal adapter covers more destinations from one device and is the simpler choice for multi-country trips. Type-specific adapters are cheaper, smaller, and usually more reliable for a single destination you'll return to often — either works electrically, since both only change plug shape.
Can an adapter make an ungrounded plug safe in a grounded socket?
A basic shape adapter won't add grounding that isn't already in your plug — it just changes the pin shape. If your device has a 3-pin grounded plug and the destination is ungrounded, look for a grounded adapter specifically, and avoid running high-power appliances through an ungrounded connection.
Is a "plug converter" the same thing as a travel adapter?
In everyday use, yes — "plug converter," "plug adapter," "power plug adapter" and "travel adapter" are all names shoppers use for the same shape-only accessory. The one term worth keeping distinct is "voltage converter," which is a different device entirely, changing the electricity rather than the pin shape.
