International Travel Plug & Voltage Guide (2026)
Plug types, voltage standards, and adapter requirements explained clearly for every major travel destination.
Every year, millions of travelers arrive at their destination only to discover their devices won't plug into the wall. Worse, some plug in anyway and watch their expensive electronics spark, smoke, or stop working entirely.
The reason is simple: the world uses 15 different plug types and two incompatible voltage systems. What works in New York won't work in London. What's safe in Tokyo could destroy your hair dryer in Paris.
Why This Guide Exists
This reference guide consolidates official plug and voltage standards from around the world. It's designed to be bookmarked, cited, and used as a planning tool before every international trip. We update it annually to reflect changes in electrical standards and travel patterns.
Common Traveler Mistakes
Assuming adapters convert voltage
Adapters only change plug shape. They don't change voltage. Using a 110V device in a 220V outlet with just an adapter can destroy it.
Not checking device labels
Most modern electronics are dual-voltage (100-240V). But hair tools, small appliances, and older devices often aren't. Always check before plugging in.
Buying cheap adapters
Low-quality adapters can overheat, fail to make proper contact, or even cause electrical fires. Invest in certified, well-reviewed adapters.
Forgetting about frequency
Some devices (clocks, turntables, older appliances) are sensitive to frequency differences (50Hz vs 60Hz). They may run slower or faster abroad.
Quick Global Summary
Quick Reference Table
This table provides a high-level overview of plug types, voltage, and adapter requirements by region. For specific country details, see the complete country-by-country table below.
| Region | Plug Types | Voltage | Frequency | Adapter Needed? | Converter Needed? |
|---|---|---|---|---|---|
| North America | A, B | 110-120V | 60 Hz | No (if from US/Canada) | No (for dual-voltage devices) |
| Europe (Continental) | C, E, F | 220-240V | 50 Hz | Yes (from US/UK) | Sometimes (hair tools) |
| United Kingdom & Ireland | G | 220-240V | 50 Hz | Yes (from most countries) | Sometimes (hair tools) |
| Asia (East) | A, B, C, I | 100-240V (varies) | 50-60 Hz | Often | Sometimes |
| Asia (Southeast) | A, C, G | 220-240V | 50 Hz | Yes (from US) | Sometimes |
| Australia & New Zealand | I | 220-240V | 50 Hz | Yes (from most countries) | Sometimes |
| South America | A, C, I (varies) | 110-240V (varies) | 50-60 Hz | Often | Sometimes |
| Africa | C, D, G, M (varies) | 220-240V | 50 Hz | Yes | Sometimes |
| Middle East | C, D, G (varies) | 220-240V | 50 Hz | Yes (from US) | Sometimes |
Important Note on Converters
"Sometimes" means you need a converter only if your device is single-voltage (e.g., 110V only). Most modern electronics (phones, laptops, cameras) are dual-voltage and only need an adapter. Always check your device label before traveling.
World Plug Types Explained
The International Electrotechnical Commission (IEC) recognizes 15 plug types used around the world, labeled A through O. Each type has a unique pin configuration, and most countries use one or more of these standards.
Understanding plug types is the first step in international travel preparation. The second step is understanding voltage, which we'll cover in the next section.
15 Global Plug Standards
Each type serves different regions and voltage systems

Common in:
Thailand (older installations)
Rarely used, being phased out
Why So Many Types?
Electrical standards developed independently in different countries during the early 20th century. By the time international travel became common, each nation had already invested heavily in its own infrastructure. Changing would cost billions and require replacing every outlet and plug in the country.
The result: travelers need adapters, and manufacturers must design products for multiple markets. The IEC has attempted to create universal standards, but adoption remains slow due to infrastructure costs.
Voltage & Frequency Explained
While plug shapes get most of the attention, voltage differences are what actually damage devices. The world uses two main voltage standards, and plugging a device designed for one into the other can cause immediate, permanent damage.
Two Voltage Systems Worldwide
Understanding the difference can save your devices
110-127V
Lower voltage system
Used in:
United States, Canada, Mexico, most of Central America, parts of South America (Colombia, Venezuela), Japan (100V), Taiwan
Frequency:
60 Hz (cycles per second)
Characteristics:
Lower voltage means higher current for the same power. Requires thicker wires. Considered slightly safer for household use due to lower shock risk.
220-240V
Higher voltage system
Used in:
Europe, UK, Australia, most of Asia, Africa, South America (Brazil, Argentina, Chile), Middle East
Frequency:
50 Hz (cycles per second)
Characteristics:
Higher voltage means lower current for the same power. More efficient for power transmission. Thinner wires needed. Used by about 80% of the world.
What "Dual Voltage" Means
Dual-Voltage Devices
Can handle both 110-127V and 220-240V automatically. Look for labels that say:
Common dual-voltage devices:
- Phone chargers (iPhone, Android)
- Laptop power adapters
- Tablet chargers
- Camera battery chargers
- Electric toothbrush chargers
- USB power banks
Single-Voltage Devices
Only work with one voltage. Labels typically show:
Common single-voltage devices:
- Hair dryers (most models)
- Curling irons / flat irons
- Electric shavers (older models)
- Small kitchen appliances
- Alarm clocks
- Older electronics (pre-2010)
Why Hair Tools Cause Problems
Hair dryers, curling irons, and flat irons draw high power (1200-1800 watts) and are often single-voltage. Plugging a 110V hair dryer into a 220V outlet with just an adapter will:
- Cause immediate overheating
- Produce smoke or burning smell
- Blow internal fuses or circuits
- Potentially cause fire or electrical shock
Solution: Buy dual-voltage hair tools, use hotel-provided dryers, or bring a heavy-duty voltage converter (not recommended for frequent use).
Frequency Differences (50Hz vs 60Hz)
Most modern electronics don't care about frequency differences. However, some devices are affected:
Clocks
Electric clocks that rely on AC frequency will run slower on 50Hz (Europe) if designed for 60Hz (US), or faster in reverse.
Motors
Devices with motors (fans, turntables) may run at different speeds. Usually not harmful, but performance varies.
Most Electronics
Phones, laptops, chargers, and modern appliances automatically handle both 50Hz and 60Hz without issues.

No adapter or converter needed (or very rarely needed)
Depends on your device voltage (check label)
Adapter definitely needed; converter for single-voltage devices
Adapter vs Converter: Clear Explanation
This is the most common source of confusion for international travelers. The terms "adapter" and "converter" are often used interchangeably, but they do completely different things.
Adapter
Changes plug shape only
What it does:
Allows your plug to physically fit into a foreign outlet. Does NOT change voltage or frequency.
When you need it:
Always, when traveling to countries with different plug types (which is most international travel).
Cost:
$10-30 for quality universal adapters
Safe for:
Dual-voltage devices only (100-240V)
Converter
Changes voltage
What it does:
Transforms voltage from 110V to 220V (or vice versa). Heavy, bulky device with internal transformer.
When you need it:
Only for single-voltage devices (hair dryers, curling irons, some small appliances).
Cost:
$30-100+ depending on wattage capacity
Limitations:
Heavy, expensive, can overheat, not recommended for extended use
The Simple Rule
If your device says "INPUT: 100-240V" on the label, you only need an adapter. If it says "110V only" or "120V only," you need a converter (or better yet, buy a dual-voltage version of that device).
Device-by-Device Examples
Phone Charger
Dual-voltage (100-240V)
All modern phone chargers are dual-voltage. Just bring a plug adapter to fit the outlet shape.
Laptop Power Adapter
Dual-voltage (100-240V)
Laptop chargers are designed for global use. Check the label to confirm, but nearly all are dual-voltage.
Hair Dryer (US Model)
Single-voltage (110V only)
Most US hair dryers are 110V only. Using them in 220V countries requires a heavy-duty converter, or better yet, buy a dual-voltage travel hair dryer.
Curling Iron / Flat Iron
Often single-voltage (110V)
Many styling tools are single-voltage. Check the label carefully. Dual-voltage models exist and are worth buying for travel.
Electric Toothbrush Charger
Usually dual-voltage
Most modern electric toothbrush chargers are dual-voltage, but check the base to be sure.
Camera Battery Charger
Dual-voltage (100-240V)
Camera chargers from major brands (Canon, Nikon, Sony) are universally dual-voltage.
Pro Tip: Skip Converters Entirely
Why converters are problematic:
- Heavy and bulky (1-3 lbs)
- Expensive ($50-150 for quality)
- Can overheat with high-wattage devices
- Not safe for continuous use
- Take up valuable luggage space
Better alternatives:
- Buy dual-voltage versions of hair tools
- Use hotel-provided hair dryers
- Air-dry hair while traveling
- Buy cheap local appliances at destination
- Invest in quality dual-voltage travel gear
Europe-Specific Plug Rules
Europe presents unique challenges because the continent uses multiple plug types despite efforts at standardization. Understanding these differences can save you from buying the wrong adapter.
Europe's Plug Puzzle
Continental Europe, UK, and Ireland use different standards
Continental Europe
Plug Types:
Type C (2 round pins), Type E (France), Type F (Germany)
Countries:
France, Germany, Spain, Italy, Netherlands, Austria, Belgium, Portugal, Greece, and most of continental Europe
Voltage:
230V, 50 Hz
Good news:
Type C plugs work in most continental European outlets. One adapter covers most countries.
UK & Ireland
Plug Type:
Type G (3 rectangular pins in triangular pattern)
Countries:
United Kingdom, Ireland, Malta, Cyprus, plus former British colonies (Malaysia, Singapore, Hong Kong)
Voltage:
230V, 50 Hz
Important:
Type G is completely different from continental European plugs. You need a separate adapter.
Switzerland
Plug Type:
Type J (3 round pins, unique to Switzerland)
Countries:
Switzerland, Liechtenstein
Voltage:
230V, 50 Hz
Compatibility:
Type C plugs (2-pin) usually work in Swiss outlets, but Type J is safer for grounded devices.
Mixed Socket Situations
Some European countries have outlets that accept multiple plug types. This is common in:
Hotels & Airports
Many European hotels install universal outlets that accept Type C, E, and F plugs. Airports often have USB charging stations and universal outlets.
Newer Buildings
Modern construction in Europe increasingly uses hybrid sockets (Type C/E/F compatible) to accommodate travelers and imported appliances.
Italy Exception
Italy officially uses Type L (3 pins in a line), but Type C plugs work in most outlets. Older buildings may have Type L only.
Denmark Quirk
Denmark uses Type K (similar to Type C but with grounding pin). Type C plugs work, but grounded devices need Type K adapter.
Smart Europe Travel Strategy
If you're visiting multiple European countries, here's the most efficient adapter setup:
Continental Europe Only
Buy one Type C adapter (or universal adapter with Type C). This works in France, Germany, Spain, Italy, Netherlands, and most of the continent.
Including UK/Ireland
Buy a universal adapter that includes both Type C and Type G. Or buy two separate adapters (one for continent, one for UK).
Multi-Device Travelers
Get a universal adapter with USB ports. Charge phone, tablet, and camera simultaneously without needing multiple adapters.
Long-Term Stays
Consider buying a power strip with USB ports at your destination. Plug one adapter into the wall, then charge everything from the strip.
UK & Ireland Are Different
This cannot be stressed enough: UK and Ireland use completely different plugs from the rest of Europe. A Type C adapter for France will NOT work in London. If your Europe trip includes the UK or Ireland, you must bring a Type G adapter separately.
How to Travel Without Power Problems
Smart Power Planning
Follow these strategies to avoid electrical disasters abroad
Check All Device Labels
Before your trip, check the label on every device you plan to bring. Look for "INPUT:" followed by voltage range.
✅ INPUT: 100-240V ~ 50-60Hz
Dual-voltage - adapter only
❌ INPUT: 120V ~ 60Hz ONLY
Single-voltage - needs converter
Pack Multi-Port Adapters
Modern universal adapters with USB ports let you charge multiple devices from one outlet.
- 4+ USB ports (USB-A and USB-C)
- Works in 150+ countries
- Built-in surge protection
- Compact and lightweight
Avoid Bulky Converters
Voltage converters are heavy, expensive, and risky. Better alternatives:
- Buy dual-voltage hair tools
- Use hotel hair dryers
- Buy cheap appliances locally
- Skip non-essential devices
Research Your Hotel
Before booking, check hotel amenities:
- Hair dryer provided?
- USB charging ports in room?
- Universal outlets available?
- Adapters available at front desk?
Many modern hotels provide adapters and have USB ports built into outlets.
Bring Power Banks
High-capacity USB power banks reduce your need for wall outlets:
- 20,000+ mAh capacity
- Multiple USB ports
- Fast charging support
- Charge overnight, use all day
Note: Airlines limit power banks to carry-on luggage only, max 100Wh capacity.
Create a Packing Checklist
Don't forget essential power items:
- Universal travel adapter
- USB charging cables
- Power bank (charged)
- Device chargers (phone, laptop, camera)
- Backup adapter (if visiting multiple regions)
Pre-Trip Power Audit
One Week Before Departure
- 1.Check voltage labels on all devices
- 2.Order adapters if needed (allow shipping time)
- 3.Test adapters with your devices at home
- 4.Charge all power banks fully
- 5.Organize cables in packing cubes
Day of Travel
- 1.Pack adapters in carry-on (not checked luggage)
- 2.Keep one adapter easily accessible
- 3.Charge devices before flight
- 4.Bring power bank in carry-on
- 5.Download offline maps (saves battery abroad)
Pro Tip: Buy Locally
If you forget an adapter or need a specific plug type, buy one at your destination airport or a local electronics store. They're often cheaper than buying "universal" adapters at home, and you'll get exactly what you need for that country.

Frequently Asked Questions
Most modern electronics (phones, laptops, tablets, cameras) have dual-voltage chargers (110-240V) and only need a plug adapter. Check your device label for "INPUT: 100-240V" to confirm. You only need a converter for single-voltage devices like some hair dryers, curling irons, or older appliances. However, converters are heavy, expensive, and risky—it's usually better to buy dual-voltage versions of these devices or use hotel-provided alternatives.
Still Have Questions?
If you have specific questions about plug types or voltage for a particular country or device, check the country-by-country table above or consult your device manufacturer's specifications. When in doubt, contact your hotel before arrival—many provide adapters or can advise on local electrical standards.
Important: This guide is updated annually, but electrical standards can change. Always verify current requirements with official sources (embassy websites, hotel staff, or local electronics stores) before traveling.
