Travel Plug Adapters and Voltage Converters by Country (2026): What Plug Do I Need, and Do I Need a Converter?

Quick answer

Most travelers only need a plug adapter, not a voltage converter. Phone, laptop, tablet and camera chargers are almost all dual voltage (the label reads INPUT 100-240V ~ 50/60Hz) and work anywhere with a cheap adapter for the local socket. Europe, Turkey and the UK run on 220 to 230 V at 50 Hz, the US and Canada on 120 V at 60 Hz, and Japan on 100 V (50 Hz in the east, 60 Hz in the west), per the IEC World Plugs listings checked in October 2026. The one thing to watch is heating appliances: a US-only 120 V hair dryer, straightener or kettle will burn out on 230 V, so take a dual-voltage model or a converter rated above its wattage.

Three tools do the travel math: the watts to amps converter to see whether a device fits an adapter's fuse, the appliance energy calculator to read a nameplate, and the transformer calculator to size a step-down unit for a heating appliance.

Plug type, voltage and frequency by country

Every row below was checked on October 21 2026 against the IEC World Plugs type listings (plug types B, C, F and G) and cross-checked against WorldStandards.eu (country pages last updated July to September 2025). The "from the US" column assumes you are packing American devices; swap it around if you are leaving from Europe. The IEC lists Turkey at 220 V and WorldStandards at 230 V, so the table shows both. Nothing in that gap changes what you need to pack.

Adapter vs voltage converter vs transformer, in plain language

A plug adapter changes the shape of the pins and nothing else. It is a passive lump of plastic and brass that lets a US flat-blade plug sit in an Italian round-pin socket. The electricity that comes out is whatever the wall supplies, so an adapter in Rome hands your device 230 V whether the device likes it or not. Adapters cost a few dollars and weigh almost nothing. Universal versions bundle several pin sets into one block, and the better ones carry a fuse: the EPICKA TA-105 listing on Walmart (October 21 2026) rates the unit at 880 W on 110 V and 1,840 W on 230 V through an 8 A fuse, and says in plain words that it does not convert voltage.

A voltage converter changes 230 V into roughly 120 V so a US-only appliance can run on it. The cheap travel kind uses electronics to chop the waveform, which is fine for a heating element and bad for anything with a motor or a circuit board, and most are rated for short use. Converters are sold by wattage: 250 W, 1,600 W, 2,000 W. The number must be higher than the wattage printed on the appliance, with a margin. A 250 W converter cannot run a 1,875 W hair dryer, which is why the Walmart listing for the BESTEK 250 W converter-adapter combo carries a reviewer warning that straighteners and dryers draw over 1,000 W and the unit is rated at 250.

A transformer is the heavy version of a converter. It uses copper windings instead of electronics, produces a clean sine wave, can run continuously, and works for motors and electronics. The cost is weight: a 2,000 W transformer weighs several kilograms. Nobody packs one for a holiday. They are the right answer for an expat moving a 120 V kitchen appliance abroad for years, not for a two-week trip.

The decision tree is short. Read the label on the device. If it says 100-240 V, buy an adapter and stop reading. If it says 120 V only and it is a heating appliance you cannot live without, buy a dual-voltage replacement or a converter rated above its wattage. If it says 120 V only and has a motor or electronics inside, leave it at home.

How to read a device label: INPUT 100-240V ~ 50/60Hz means dual voltage

Every charger and most appliances carry a small block of text on the brick, the plug or the base. The line that matters starts with INPUT. Here is what each piece means, using the format most chargers use.

The tilde (~) after the voltage means alternating current, which is what every wall socket supplies. 50/60Hz means the device accepts both grid frequencies. If the label shows only 60Hz, it will still usually work on a 50 Hz grid if it is a switching power supply, but a motor-driven appliance such as a clock, a fan or a turntable may run slower. If the label is worn off, treat the device as single voltage and check the manufacturer's spec page, which is what I did for every product named in this guide.

To translate a nameplate into something you can compare against an adapter's fuse, the appliance energy calculator takes watts or amps and the volts to watts calculator does the multiplication for you.

Is my iPhone charger dual voltage?

Yes. Apple's support page "About Apple USB power adapters" (published July 11 2024, checked October 21 2026) states that Apple USB power adapters are designed for use with power sources rated to provide 100 V AC to 240 V AC at 50 Hz to 60 Hz. That one sentence covers the 20 W USB-C adapter (19 dollars on apple.com in October 2026), the older 5 W cube, the iPad adapters and the USB-C adapters that ship with MacBooks. The only thing that changes between countries is the removable or fixed prong on the brick, which is why Apple sells plug-shape kits and why a 9 dollar adapter is all you need.

The same is true of nearly every laptop and camera charger made in the last fifteen years. The Sony BC-QZ1 camera battery charger lists an AC input of 100 to 240 V AC at 50/60 Hz on the B&H spec sheet (checked October 21 2026). Dell, Lenovo, HP and Apple laptop bricks all carry the 100-240 V line. The electronics that make this possible, a switch-mode power supply, are cheaper to build for the whole world than for one region, so manufacturers stopped making single-voltage chargers for anything small. Before you buy a converter for "electronics," look at the brick. You almost certainly do not need one.

Two caveats. A USB power bank or a cheap no-name charger from a market stall may not carry a 100-240 V rating, and some older electric toothbrush and shaver bases are 120 V only. Check the label on each one rather than assuming the whole bag is safe.

Can I use my hairdryer in Europe?

Only if it is dual voltage, and most full-size US dryers are not. This is the single most common way travelers destroy an appliance, and the reason is physics rather than bad luck. A heating element is a fixed resistance. Power through a resistance rises with the square of the voltage, so a 120 V dryer on a 230 V socket does not run at double power, it runs at (230 / 120) squared, which is 3.67 times its rating. The element glows, the thermal fuse opens if you are lucky, and the motor or the fan housing fails if you are not.

Here is the worked example I use for every heating appliance:

Three real products show the three cases. The Dyson Supersonic sold in the US is single voltage: Dyson's own US tech spec sheet lists an input of 120 V / 60 Hz at 1,600 W. It will not survive a European socket, and converter listings commonly carry an "except Dyson" exclusion because its digital motor does not tolerate the chopped output of a travel converter (the Home Depot listing for a 2,000 W step-down converter, checked October 21 2026, says exactly that). The Conair 127NPN compact folding dryer is the opposite case: 1,875 W, sold as dual voltage for worldwide use at 36.26 dollars on conair.com in October 2026, with a 125 V / 250 V switch you set with a coin before plugging in. The ghd range splits the difference: ghd's help page says its stylers (excluding model 3.1b) and the ghd curve range have universal voltage and need only a travel adapter, while the ghd air, Helios and Duet Style dryers bought on the US site will only work where a 110-120 V supply is available.

So the practical rules are: a dual-voltage travel dryer (around 36 dollars) beats a converter (64 to 89 dollars for a 2,000 W unit at Newegg and Home Depot in October 2026) on price, weight and reliability. If you must bring a single-voltage dryer, the converter must be rated above the dryer's wattage, so a 1,875 W dryer needs at least a 2,000 W converter, and you should expect it to be rated for intermittent use only. Never plug a 120 V-only heater, kettle, iron, curling iron or steamer into a 230 V socket through a plain adapter, even for a moment. Straighteners deserve a specific warning: many are dual voltage, many are not, and the label on the cord or the inside of the hinge is the only way to know.

Run your own dryer or straightener through the watts to amps converter at 230 V and again at 120 V to see what an adapter's fuse or a converter is being asked to carry.

What plug do I need in Italy?

A Europe adapter (type C) covers chargers; a type L adapter covers grounded devices. Italy is listed by the IEC at 230 V, 50 Hz with plug types C, F and L. The Italian type L socket is the odd one: three round pins in a straight line, in a 10 A version and a 16 A version with thicker, wider-spaced pins. A two-pin type C Europlug, which is what every "Europe adapter" is, fits the 10 A type L socket and fits the German-style type F sockets that most hotels and newer apartments have. Where it fails is a grounded three-pin device such as a laptop brick with a three-prong cord, or a 16 A type L socket in an older building, which accepts only the 16 A type L plug. For those, a 3-pack of grounded type L adapters was 9.08 dollars on Walmart on October 21 2026 (rated 10 A at 250 V, and the listing itself says not for hair dryers or curling irons). If you only carry phone, laptop and camera chargers, the Europe adapter is enough.

Plug adapter for Europe: which one covers France, Germany, Spain and the rest

One type C (Europlug) adapter covers the whole continent for two-pin chargers. The IEC lists Germany, Spain, Greece, Austria, the Netherlands, Portugal, Norway and Turkey on type C and F, and France on type C and E, all at 230 V (Turkey at 220 V in the IEC table) and 50 Hz. Types E and F are the grounded sockets: type F (Schuko) has two earth clips on the sides, type E has a round earth pin sticking out of the socket. Both accept the two-pin type C plug, which is why the IEC describes the Europlug as fitting any socket that takes 4.0 to 4.8 mm round contacts on 19 mm centres. A type C plug is limited to 2.5 A by design, which is 575 W at 230 V: plenty for every charger, not enough for a kettle or a dryer.

If you need ground, buy an E/F hybrid adapter, which has both the side clips and the hole for the French pin. Avoid the ungrounded universal blocks for anything with a metal case. And note what Europe does not include: the UK and Ireland use a different plug entirely (next section), Switzerland uses type J, and Denmark has its own type K socket (the IEC lists Denmark on type F as well, and a Europlug fits a type K socket). Within the table in this guide, one Europe adapter plus one UK adapter covers every country.

What plug do I need in Greece?

A Europe adapter. Greece is listed by the IEC at 230 V, 50 Hz on plug types C and F, and WorldStandards gives the same. There is no Greek-specific socket; the islands and the mainland use the same Schuko-style outlets as Germany. Your 100-240 V chargers need only the two-pin adapter. A US-only hair dryer needs a converter or a dual-voltage replacement, same as everywhere else in Europe. One practical note for island hotels: wall sockets in older rooms are often ungrounded type C, so a grounded E/F adapter will not seat fully and you may need the plain two-pin version too.

What plug do I need in Turkey?

A Europe adapter, the same type C or F as Greece and Germany. The IEC lists Turkey on plug types C and F at 220 V, 50 Hz; WorldStandards lists 230 V. The two figures are within the normal tolerance band of a 230 V grid, and no adapter or converter decision changes between them. Istanbul hotels generally have the grounded type F socket; older buildings in Cappadocia and the coast often have the recessed two-pin type C. For a US traveler, pack the same Europe adapter you would take to Italy, and the same rule applies to heating appliances: 120 V only means converter or stay home.

Plug adapter for UK

A type G adapter, which is a different shape from the Europe adapter. The UK and Ireland use the three-rectangular-pin type G plug at 230 V, 50 Hz. The IEC type G listing describes the incorporated fuse in every UK plug, typically 3 A for small appliances such as computers and 13 A for heavy-duty ones like heaters, and the shutters on the live and neutral contacts that block anything but a proper plug. Those shutters are why a Europlug will not go into a UK socket even though the voltage is the same: the long earth pin opens the shutters, and a two-pin plug has no earth pin. Buy the UK adapter separately, or a universal block that includes the type G pins.

Two UK details catch people out. First, many UK bathrooms have no ordinary socket at all, only a two-pin shaver socket near the mirror. Those are low-power isolation outlets meant for shavers and toothbrushes and will not run a hair dryer. Second, the adapter's fuse matters: a universal adapter rated 1,840 W at 230 V through an 8 A fuse is fine for chargers, marginal for a 1,600 W dual-voltage dryer set to 250 V, and will blow on anything bigger. If you want the running cost of what you plug in once you arrive, the UK electricity cost guide has the current unit rates.

Do I need a converter in Japan?

Not for chargers, and not for most US appliances. Japan runs on 100 V, lower than anywhere else in this guide, and uses the same flat two-pin type A socket as the US. Per the IEC type B listing it is 100 V at 50 Hz or 60 Hz; the Embassy of Japan in Singapore spells out the split as eastern Japan including Tokyo at 50 Hz and western Japan including Nagoya, Kyoto and Osaka at 60 Hz. A charger marked 100-240 V covers 100 V by definition. A US two-pin plug goes straight into a Japanese socket with no adapter at all. The one thing to know is that many Japanese sockets have only the two flat slots and no round ground hole, so a US three-pin laptop cord needs a small three-to-two adapter.

A US-only 120 V appliance will run in Japan, just weaker: the worked example above gives about 69 percent of rated power at 100 V, so a 1,875 W dryer behaves like a 1,300 W one. Motors with a fixed speed, such as some clocks and older shavers, run about 17 percent slower on the 50 Hz grid in Tokyo. Nothing is damaged, it is simply less powerful.

Voltage converter for Japan: when the answer is actually yes

The traveler who does need a converter in Japan is the one arriving from Europe, the UK, Australia or anywhere else on 230 V with a single-voltage heating appliance. A 230 V kettle or dryer on a 100 V socket delivers (100 / 230) squared, or about 19 percent of its rated power: it will barely warm up. That traveler needs a step-up converter rated above the appliance's wattage, plus a type A plug adapter. In practice almost nobody does this, because dual-voltage dryers and hotel-room dryers are easier. Japanese hotels nearly always provide a dryer. The second group who ask this question are people shipping Japanese 100 V appliances home to the US, where the reverse problem applies: a 100 V rice cooker on 120 V runs at 144 percent of rated power and shortens its own life. The transformer calculator sizes the step-down unit for that case.

Power adapter for Japan: what searchers actually need

Most people typing "power adapter for Japan" want one of three things, and only one is a purchase. If you have a US two-pin charger, you need nothing. If you have a US three-pin plug, you need a three-to-two grounding adapter, or a universal block whose type A pins are two flat blades. If you are coming from Europe, the UK, Australia or Asia, you need a type A adapter and, for anything with a power brick, nothing else: the 100-240 V input already covers 100 V. The term "power adapter" is also Apple's name for its charger brick, which, as covered above, is rated 100-240 V and works in Japan as-is. The thing almost no traveler needs is a voltage converter for Japan, unless they are carrying a 230 V-only heating appliance.

Do I need a converter in Canada?

No. Canada is listed by the IEC on plug types A and B at 120 V, 60 Hz, identical to the US, and WorldStandards confirms it. A US device works unchanged, with no adapter and no converter, in every province. Travelers arriving from Europe, the UK, Japan or Australia need a type A or B plug adapter, and if they carry a 230 V-only heating appliance it will run at about 27 percent of rated power at 120 V, so it needs a step-up converter or should stay home. Everything with a 100-240 V brick, which is every phone and laptop charger, needs the plug adapter only. Once you are plugged in, the Canada electricity rates by province guide covers what the power costs.

How to size a voltage converter for a hair dryer or straightener

If you have decided to carry a single-voltage heating appliance, three numbers decide the converter. First, the appliance wattage from its label. Second, a margin, because converters are rated optimistically and a dryer's startup draw is above its running draw: 20 to 25 percent is the usual allowance. Third, the current on each side, because the converter's own plug has to fit through the local socket and its output has to carry the appliance.

Both 2,000 W units I checked on October 21 2026 (63.99 dollars at Newegg, 88.59 dollars at Home Depot) state an input of 220 to 240 V and an output of 100 to 120 V, and both are marketed for hair styling tools. That is the honest use case for a travel converter: a resistive heater, used for ten minutes at a time. Treat anything with a motor, a compressor or a circuit board as off limits unless the converter is a true transformer. The watts to amps converter gives the two current figures above for any wattage and voltage.

What travel adapters and converters cost (as of October 2026)

Prices below are single retail listings checked on October 21 2026, not survey averages. They move with promotions, so treat them as the order of magnitude: adapters are a single-digit to low-double-digit purchase, dual-voltage dryers are mid-double-digit, and converters cost more than the dryer they are meant to protect.

The pattern is obvious once it is in a table: the converter costs roughly twice what a dual-voltage dryer costs, weighs more, and is the only item on the list that can fail in use. For most trips the right shopping list is one Europe adapter, one UK adapter if the itinerary includes Britain or Ireland, and a dual-voltage dryer if the hotel's dryer will not do.

Safety note. Heating appliances are the fire risk in travel electrics. Never plug a 120 V-only hair dryer, straightener, kettle, iron or steamer into a 220 to 240 V socket through a plain plug adapter, and do not run any appliance through a converter rated below the appliance's wattage. Cheap unbranded converters and adapters without a fuse or a safety mark (UL, CE, UKCA) have no overload protection; if one gets hot, unplug it. This guide describes nominal national voltages and plug standards; individual buildings, cruise ships and older hotels can differ. Electrical work carries safety and legal risk.
