An international plug adapter lets you connect your devices to foreign electrical outlets. This guide covers outlet types (A through N), voltage (110V vs 220V), and frequency for 60+ countries — plus a home country comparison to tell you exactly what adapter you need and whether your device can handle the voltage difference.

Plug Type Quick Reference
Voltage warning: Blue (110-127V) devices from North America may be damaged in orange (220-240V) countries unless labeled "Input: 100-240V." Always check your device label before plugging in.
How to Use the International Plug Adapter Guide
Plugging the wrong adapter — or worse, no adapter — into a foreign socket can damage your devices or leave you without power. This guide covers 60+ countries to make sure you're prepared before you travel.
Step 1: Select Your Home Country
Select your home country from the dropdown to activate the "Adapter Needed?" column. This column will show you instantly whether you need an adapter for each destination, or if your home plug already fits. US travelers, for example, need adapters for virtually everywhere except Canada, Mexico, Japan, and a few Central American countries.
Step 2: Search Your Destination
Type your destination country or filter by region. The table shows plug types, voltage, and frequency. Blue voltage badges (110-127V) are low-voltage like North America. Orange badges (200-240V) are high-voltage like Europe. The voltage difference matters for non-dual-voltage devices.
Step 3: Check Your Device Label
Find the small label on your device's power brick or charger. If it says "Input: 100-240V, 50/60Hz" — you have a dual-voltage device and only need a physical plug adapter, not a voltage converter. This is true for most modern laptop chargers, phone chargers, and camera batteries. If the label says "110V" or "120V" only, you need a voltage converter when traveling to 220V countries.
Common Plug Types Explained
Type A/B (two flat prongs) is the North American standard at 110-120V. Type C/E/F (two round prongs) dominates continental Europe at 220-230V. Type G (three rectangular blades) is used in the UK, Singapore, and Malaysia. Type I (angled flat pins) covers Australia, New Zealand, and China. A universal travel adapter ($15-30) covers all four major types and is the best investment for multi-country trips.
High-Risk Appliances
Hair dryers, curling irons, straighteners, and electric shavers are often rated for only 110V. Plugging a 110V hair dryer into a 220V outlet (even with an adapter) will immediately burn it out. Buy a travel hair dryer rated 100-240V, or use the hotel's dryer. Medical devices and CPAP machines usually support dual voltage but verify before travel — your health depends on it.
FAQ
Is this plug adapter guide free?
Yes, completely free. No account required. All outlet data is embedded and runs locally in your browser.
Is my data safe when using this tool?
Yes, everything runs in your browser. No data is transmitted anywhere.
What is the difference between a plug adapter and a voltage converter?
A plug adapter only changes the physical shape of the plug so it fits the outlet. It does NOT convert voltage. A voltage converter changes the electrical voltage — critical if your device only handles 110V/120V and the destination uses 220V/240V. Most modern electronics (laptops, phones, cameras) are dual-voltage (100-240V) and only need an adapter, not a converter.
How do I know if my device is dual-voltage?
Check the label on your device's power brick or charger. It will say something like 'Input: 100-240V, 50/60Hz' — this means it's dual-voltage and only needs a plug adapter. If it says 'Input: 110V' or '120V' only, you need a voltage converter when traveling to 220V countries.
Which plug adapter type do I need for Europe?
Most of continental Europe uses Type C (two round pins) or Type E/F (two round pins with grounding). UK and Ireland use Type G (three rectangular pins). If coming from North America with Type A/B plugs, you need a Type C or Type E/F adapter for continental Europe, and a Type G adapter for the UK. A universal travel adapter covers all European countries.
Can I use my US devices in Europe?
Modern US electronics (phone chargers, laptop adapters) are typically dual-voltage (100-240V) and only need a plug adapter, not a converter. Always verify on the device label before plugging in. Older appliances like hair dryers, electric razors, and curling irons are often 110V-only and will be damaged or destroyed by 220V without a converter.
What is a universal travel adapter?
A universal travel adapter covers multiple plug types (typically A, B, C, E/F, G, I) in one unit. Good ones include USB-A and USB-C charging ports. They cost $15-30 and are worth buying for multi-country trips. They do NOT include voltage conversion — just physical plug shape adaptation.
