Do I need a plug adapter for United States to Ireland?

Yes. United States uses Type A, Type B and Ireland uses Type G, so the plug shapes do not match and you need a travel adapter.

Do I need a voltage converter?

Only for single-voltage appliances. United States runs at 120 V and Ireland at 230 V, so anything not marked 100–240 V needs a converter.

Will my phone and laptop chargers work in Ireland?

Yes, in almost every case. Modern chargers are dual-voltage (100–240 V, 50/60 Hz), so they only need the plug to fit — a simple adapter if the socket shapes differ.

Can I use my United States plug in Ireland?

A straight answer for United States devices on a Ireland trip — plugs, voltage and frequency compared.

Adapter and a voltage check

Ireland uses Type G sockets at 230 V / 50 Hz, so your Type A and Type B plug will not fit. You need a travel adapter, and any device that is not marked 100–240 V needs a converter.

What the sockets look like

United States

Ireland

The two countries sit in different voltage classes: United States supplies 120 V and Ireland supplies 230 V. That matters more than the plug shape, because a device built for one voltage can fail immediately on the other. Anything marked 100–240 V is fine; anything that names a single voltage is not.

The supply frequency differs (60 Hz against 50 Hz). Chargers, laptops and LED lamps do not care. Mains-powered clocks and older motors do: a 50 Hz fan on a 60 Hz supply runs about 20% faster.

What to pack

A travel adapter from Type A, Type B to Type G — the shapes are incompatible.
A converter (not just an adapter) for any device that is not marked 100–240 V.
Nothing extra for frequency: chargers and laptops are unaffected, though mains clocks and older motors can run fast or slow.
A second adapter if you travel with a partner — they are cheap and easy to lose.

What to buy for this trip

★ RecommendedUniversal travel adapter

EPICKA 75 W GaN universal travel adapter

One block that covers US, UK, EU and Australian sockets, with 75 W of USB-C charging — enough for a laptop without carrying its power brick.

Plugs for US / UK / EU / AU sockets
3× USB-C (75 W total) + 2× USB-A
Universal AC socket, fused, up to 2000 W
About 250 g

It does not convert voltage. A 120 V appliance still gets 230 V in Europe, whatever adapter you use.

Best for: Phones, laptops, cameras, tablets and anything dual-voltage.

★ RecommendedStep-down converter

TESSAN 230 W step-down voltage converter

Takes 220–240 V down to 110–120 V for single-voltage North American appliances, with three AC sockets and four USB ports so it doubles as a charging hub.

230 W continuous
220–240 V in, 110–120 V out
3 AC outlets + 4 USB ports
EU / UK / AU / IT input plugs

Not for: Hairdryers, heaters and kettles, or devices under about 5 W such as electric shavers. Those need a bigger transformer or a dual-voltage device.

Best for: CPAP machines, fans, monitors, printers and small kitchen appliances.

On a budget? A single-purpose adapter costs a fraction of the universal block — it does the same job for one trip, but only for one socket type.

Budget optionCeptics Type G adapter, 3-pack (universal input)

Fits UK, Ireland, UAE, Singapore, Malaysia, Hong Kong and Gulf sockets. Takes any two- or three-pin plug on the other side.
