One of the biggest misconceptions about European travel is that you need one plug adapter. In reality, Europe has at least seven different outlet types across its countries โ but a single universal adapter handles all of them.
This guide maps out exactly which plug types you will encounter across Europe, shows you the compatibility between them, and analyzes popular multi-country routes to prove you only need one adapter. If you are also unsure about voltage, see our 110V/220V voltage explainer.
Europe's Plug Types at a Glance
| Plug Type | Shape | Countries | Grounded? |
|---|---|---|---|
| Type C | Two round pins (4.0mm), no ground | Most of Europe (universal fit in almost all European outlets) | No |
| Type E | Two round pins + hole for ground pin | France, Belgium, Poland, Czech Republic, Slovakia | Yes (via socket pin) |
| Type F | Two round pins + side ground clips | Germany, Austria, Netherlands, Spain, Sweden, Norway, Finland, Portugal, Greece | Yes (via clips) |
| Type G | Three rectangular pins | UK, Ireland, Malta, Cyprus, Gibraltar | Yes |
| Type J | Three round pins (offset ground) | Switzerland, Liechtenstein | Yes |
| Type K | Three round pins (different offset from J) | Denmark, Greenland | Yes |
| Type L | Three round pins (inline) | Italy, Chile | Yes |

The Compatibility Secret: Type C Fits (Almost) Everything
Here is the key insight most travelers miss: a Type C plug (two round 4.0mm pins, no ground) physically fits into Type E, F, J, K, and L outlets. This means a simple Type C adapter covers France, Germany, Switzerland, Denmark, Italy, Spain, Portugal, Greece, and most other continental European countries.
| Your Plug | Type C outlet | Type E outlet | Type F outlet | Type J outlet | Type K outlet | Type L outlet | Type G outlet |
|---|---|---|---|---|---|---|---|
| Type C plug | Yes | Yes | Yes | Yes | Yes | Yes (10A) | No |
| Type G plug | No | No | No | No | No | No | Yes |
| US Type A/B plug | No | No | No | No | No | No | No |
The one major exception is Type G (UK). The UK's three rectangular pins are completely different from every other European outlet. If your trip includes both the UK and continental Europe, you need an adapter that covers both โ or a universal adapter.
Popular Multi-Country Routes Analyzed
Route 1: Paris โ Geneva โ Milan โ Rome โ Vienna
| City | Country | Outlet Types | Type C works? |
|---|---|---|---|
| Paris | France | Type E | Yes |
| Geneva | Switzerland | Type J | Yes |
| Milan | Italy | Type L / Type C | Yes |
| Rome | Italy | Type L / Type C | Yes |
| Vienna | Austria | Type F | Yes |
Verdict: One adapter covers the entire route. Even Switzerland and Italy's unique sockets accept Type C pins.
Route 2: London โ Paris โ Amsterdam โ Copenhagen โ Stockholm
| City | Country | Outlet Types | Type C works? |
|---|---|---|---|
| London | UK | Type G | No โ need Type G adapter |
| Paris | France | Type E | Yes |
| Amsterdam | Netherlands | Type F | Yes |
| Copenhagen | Denmark | Type K | Yes |
| Stockholm | Sweden | Type F | Yes |
Verdict: You need two adapter types โ Type C for continental Europe and Type G for London. A universal adapter like the DOACE GaN covers both without switching.
Route 3: Barcelona โ Lisbon โ Madrid โ Munich โ Prague
| City | Country | Outlet Types | Type C works? |
|---|---|---|---|
| Barcelona | Spain | Type F | Yes |
| Lisbon | Portugal | Type F | Yes |
| Madrid | Spain | Type F | Yes |
| Munich | Germany | Type F | Yes |
| Prague | Czech Republic | Type E | Yes |
Verdict: One Type C adapter covers the entire route. All countries use Type E or F, both of which accept Type C plugs.
The Simple Answer: One Universal Adapter
Instead of figuring out individual plug types for each country, a universal travel adapter covers all of Europe (and 200+ other countries) in one device. The DOACE 70W GaN Travel Adapter includes interchangeable prongs for US, EU, UK, and AU โ meaning it works in every European country, including the UK.
- EU prong: Works in France, Germany, Spain, Italy, Switzerland, Denmark, and all continental Europe
- UK prong: Works in UK, Ireland, Malta, Cyprus
- USB-C PD 70W: Charges phones, tablets, and laptops directly โ reducing adapters needed
- Pass-through AC outlet: Plug in a CPAP, laptop charger, or other device simultaneously

Frequently Asked Questions
I bought a "European adapter" on Amazon. Will it work in Switzerland?
It depends on the type. If it has a simple Type C plug (two round pins, no ground), it will physically fit into Swiss Type J outlets. However, many cheap "European adapters" sold on Amazon have thicker Type F-style pins that may not fit Type J's narrower socket opening. A universal adapter eliminates this risk.
Do I need a voltage converter for Europe?
Only for 120V-only devices like US hair dryers or countertop appliances. All modern electronics (phones, laptops, cameras, tablets, electric toothbrushes) have dual-voltage chargers (100โ240V) and only need a plug adapter. See our power label reading guide to check your devices.
Italy has Type L outlets. Will my standard European adapter work?
Yes โ but with a caveat. Italy uses two sizes of Type L: the 10A version (smaller holes) and the 16A version (larger holes). A Type C plug fits the 10A version, which is the most common in hotels and homes. The 16A outlets are used for high-power appliances. Most travelers will never encounter a 16A-only outlet. A universal adapter handles both.
Should I bring two adapters for a multi-country trip?
Bringing two is smart for convenience โ one for the hotel room and one for your day bag. But you do not need two different types of adapters. Two identical universal adapters cover every country. If you use the DOACE GaN adapter, the USB-C ports mean you may not need a second one at all โ one adapter charges your phone, laptop, and plugs in your CPAP simultaneously.
What about cruise ships in Europe?
Cruise ships often have US-style Type A/B outlets in cabins, regardless of their European itinerary. Some newer ships also include European outlets. Check with your cruise line before departure. For cabin power setup advice, see our cruise-specific guides on the DOACE blog.
