Plugs, Sockets and Voltage in Dubai: What to Pack

Dubai, and the United Arab Emirates as a whole, runs on the same electrical standard as the UK and Ireland. The socket takes the Type G three-pin plug — three rectangular pins in a triangular layout — and the mains supply is 230 volts at 50 hertz.

If a device and its plug both come from the UK or Ireland, they work here with nothing extra. Everyone else needs to think about two separate things: the plug shape and the voltage.

Whether you need an adapter depends only on the shape of your plug, not on the country you flew in from. The question is simple: do your plugs have the three rectangular Type G pins, or something else?

If they are anything other than Type G, you need an adapter to make them fit the socket. That is a different job from the voltage, which the next section covers.

This is the part that catches people out. A plug adapter only lets your plug physically fit the socket. It does not change the 230-volt supply at all.

Most modern chargers cope with that supply on their own. Look at the small print on the charger or its label for the word INPUT. If it reads 100-240V, the device is dual-voltage and works anywhere, so a plug adapter is all it needs. Phone, laptop, tablet and camera chargers almost always fall into this group.

A single-voltage device is the exception. If the label says only 110-120V — as some US hairdryers, straighteners and other heating appliances do — then 230 volts is roughly double what it expects. Plugging it in through an adapter alone can damage it. For those you need a voltage converter, which actually steps the voltage down, not just a plug adapter.

Most of the rooms you are likely to stay in have standard Type G sockets. There are two common variations worth knowing about before you travel.

• Some older or budget buildings have Type C sockets, which take two round pins. A universal adapter covers both Type G and Type C, so either way you are sorted.
• Newer hotels increasingly build USB sockets into the wall or the bedside units. Where those exist, you can charge a phone or tablet straight from the USB port with no adapter at all.

You can keep this simple. A little preparation before you fly means you are not hunting for a shop on your first evening.

• A Type G adapter, or a universal adapter that includes Type G — one for each device you want to charge at the same time.
• A quick read of the INPUT label on each charger before you pack, so you know what is dual-voltage and what is not.
• Leave a 110-120V-only hairdryer or straightener at home. Hotels usually provide a hairdryer, so you may not need your own at all.

A single universal adapter plus a quick read of each device's INPUT label covers almost every traveller. The one thing it will not fix is a single-voltage heating appliance — for that, leave it at home rather than risk it on the 230-volt supply.
