Trip Match Summary
Use this quick match to understand what changes when you take US devices to Ireland.
United States
Common plugs: Type A and Type B
Ireland
Common outlet: Type G
Usually needed
A US plug will not normally fit an Irish Type G socket.
Check the label
US power is commonly 120V / 60Hz. Ireland is commonly 230V / 50Hz.
Best quick answer: pack a US-to-Ireland Type G plug adapter. For phones, tablets, laptops, camera chargers, and many USB chargers, a plug adapter is often enough if the charger label says Input: 100–240V. For hair dryers, curling irons, travel kettles, and other high-power appliances, check the voltage label carefully before plugging in.
A plug adapter does not convert voltage. It only changes the plug shape so your device can physically fit the outlet.

Quick Answer for US Travelers Going to Ireland
You should usually bring a Type G travel adapter for Ireland. Ireland uses the same general plug shape as the United Kingdom: a large three-pin plug with rectangular pins. Standard US plugs, including Type A two-flat-pin plugs and Type B grounded plugs, do not fit Irish outlets.
The bigger question is voltage. The United States commonly uses 120V / 60Hz, while Ireland commonly uses 230V / 50Hz. That difference matters more for heat-producing appliances than it does for most modern chargers.

Plug Compatibility from the US to Ireland
US plugs and Irish outlets are not the same shape. In the US, most small devices use Type A or Type B plugs. In Ireland, standard wall outlets are commonly Type G, with three rectangular slots.
That means a US charger will usually need a US-to-Type-G plug adapter before it can fit into an Irish wall socket. This applies to phone chargers, laptop chargers, camera chargers, electric shavers, and many other travel devices.
A plug adapter is a shape adapter. It does not make a US-only 120V device safe for Ireland’s 230V supply. Keep that distinction clear:
- Plug adapter: changes the plug shape.
- Voltage converter: changes the electrical voltage for certain devices.
- Dual-voltage charger: can usually handle both US and Irish voltage ranges.
Voltage Difference Between the US and Ireland
The voltage difference is the part that can damage the wrong device. US household outlets are commonly 120V, while Ireland commonly uses 230V. Ireland also uses 50Hz frequency, while the US commonly uses 60Hz.
For many modern electronic chargers, this is not a problem because the charger is designed to accept a wide input range. You are looking for a label that says something like Input: 100–240V, 50/60Hz. That wording usually means the charger can work in both the US and Ireland, as long as you use the correct plug adapter.
For simple heat devices, the risk is higher. A US-only 120V hair dryer plugged into 230V power can overheat, fail, or become unsafe. Do not rely on the plug adapter to protect it.
Do You Need a Plug Adapter?
Yes, in most cases. A US plug will not normally fit directly into an Irish Type G outlet. For this trip, your packing list should include a Type G plug adapter or a universal travel adapter that supports Type G outlets.
Make sure the adapter has the right socket side for your US plug. If your device has a grounded Type B plug, use an adapter that can accept a grounded US plug properly. Cheap or loose adapters can be frustrating, especially for heavier chargers.
AdapterMatch rule: match the trip first, then match the device. For the US to Ireland, the trip usually needs a Type G plug adapter. The device label decides whether voltage is safe.
Do You Need a Voltage Converter?
You may need a voltage converter only if your device is single voltage and not rated for Ireland’s 230V supply. The easiest way to check is to read the label on the charger, power brick, or appliance body.
If the label says Input: 100–240V
If your charger says Input: 100–240V, it is usually designed for international voltage ranges. In that case, you normally only need the correct Type G plug adapter for Ireland.
If the label says only 120V
If the label says only 120V, 110V, or a narrow US-only range, do not plug it into an Irish outlet with just an adapter. That device may need a proper voltage converter, or it may be better to leave it at home and use a travel-ready replacement.
If the device is high power
High-power appliances need extra caution. Hair dryers, curling irons, flat irons, clothes irons, heating pads, and travel kettles can draw much more power than chargers. Even when a converter exists, not every converter is suitable for every appliance.
Phone Charger Guidance
Most modern phone chargers are made for international travel, but you should still check the small printed label. If it says Input: 100–240V, 50/60Hz, the charger should usually work in Ireland with a Type G plug adapter.
If your phone charges through USB-C, you may also use a USB-C charger that is clearly rated for 100–240V. The cable does not decide voltage safety; the charger or power adapter does.
Laptop Charger Guidance
Laptop chargers are commonly dual voltage. Look at the power brick, not just the laptop itself. If the brick says Input: 100–240V, it is usually suitable for Ireland’s voltage range.
You will still usually need a Type G adapter for the wall outlet. Some travelers prefer bringing a replacement power cord with a Type G plug for the laptop charger brick, but a simple travel adapter is often enough for short trips.
Hair Dryer and Curling Iron Warning
Hair dryers, curling irons, flat irons, and similar styling tools are the most common problem devices on US-to-Ireland trips. Many are designed for 120V only. If you plug one into Ireland’s 230V supply using only a plug adapter, it may overheat or fail.
Use one of these safer options:
- Bring a device that clearly says it supports 100–240V or 220–240V.
- Use a dual-voltage travel hair tool and set it correctly before plugging it in.
- Use a suitable local appliance at your accommodation when available.
- Avoid using US-only 120V heat appliances in Ireland with just a plug adapter.
A plug adapter alone is not a safe solution for a US-only 120V hair dryer in Ireland.
What About 50Hz and 60Hz?
Frequency is different too: Ireland commonly uses 50Hz, while the US commonly uses 60Hz. For many modern chargers labeled 50/60Hz, this is usually fine.
Frequency can matter more for some clocks, motors, medical equipment, and older devices. If a device relies on motor speed, timing, or medical performance, check the label and manufacturer instructions before travel.

What to Pack for Ireland from the US
For a normal US-to-Ireland trip, your travel power kit can stay simple. Pack based on your actual devices, not just the destination country.
- A Type G plug adapter for Ireland.
- A spare adapter if you need to charge multiple devices at once.
- USB-C or USB chargers labeled Input: 100–240V.
- Your laptop power brick, after checking the voltage label.
- A dual-voltage hair tool if you truly need one.
- Any medical device power supply, manual, and backup power plan if relevant.
If you are staying in several hotels or older buildings, outlet placement and availability can vary. A compact adapter setup is often easier than carrying several large appliances.
Common Mistakes to Avoid
- Buying a European Type C adapter and assuming it works in Ireland. Ireland commonly uses Type G, not the two-round-pin outlet used in many mainland European countries.
- Thinking a universal adapter automatically converts voltage. A plug adapter does not convert voltage.
- Plugging a 120V-only hair dryer into a 230V outlet.
- Checking the device box but not the actual charger label.
- Forgetting that grounded US plugs may need an adapter that accepts Type B properly.
FAQ
Do US plugs work in Ireland?
No, not directly in most cases. US Type A and Type B plugs usually do not fit Ireland’s Type G outlets. You will normally need a Type G plug adapter.
Is Ireland the same plug as the UK?
Yes, Ireland commonly uses Type G outlets, which are also used in the UK. Still, check your accommodation if you have unusual or high-power equipment.
Can I charge my iPhone in Ireland with a US charger?
Usually yes, if the charger label says Input: 100–240V. You will still need a Type G plug adapter unless your charger already has a Type G plug.
Do I need a voltage converter for Ireland from the US?
Not for many modern phone and laptop chargers that support 100–240V. You may need one for single-voltage 120V devices, especially high-power appliances.
Can I use my US hair dryer in Ireland?
Only if it is rated for Ireland’s voltage or is clearly dual voltage and set correctly. A US-only 120V hair dryer should not be used with just a plug adapter.
What adapter should I buy for Ireland?
Look for a Type G travel adapter that accepts US Type A and Type B plugs. If your device has a grounded plug, choose an adapter that supports grounded plugs properly.
