UK to Antigua and Barbuda Plug Adaptors
Our Adaptor Recommendation
Types A and B are earthed and unearthed variants of the same socket so a type A/B plug adaptor is all that you will need for a trip to Antigua and Barbuda.
A simple unearthed adaptor is compact and enough for phone chargers and most travel electronics. Models with USB or USB-C ports are useful when charging several devices, while PD ports are suitable for compatible laptops. For earthed equipment or several mains-powered appliances, choose an earthed adaptor or power strip.
Our recommendations for the best UK to Antigua and Barbuda travel adaptors ensure that you'll always be able to connect your British type G plugs to the Antigua and Barbudan type A and B sockets.
Choosing the Right Power Adaptor
Having overcome the pesky differences in plug types and socket configurations you now need to decide what sort of adaptor suits your own, specific needs.
If you decide to buy an adaptor, here are some useful features to consider:
- Earthed vs unearthed adaptors
- Multiplug adaptors
- Extensions / power strip adaptors (great for families)
- Integral USB / USB-C ports for charging devices like phones and tablets
- Dedicated charging hubs with multiple ports
- USB-C port with power delivery (PD) using GaN technology for laptop charging up to 140W
- Universal adaptors (any plug to any socket) for the ultimate in versatility
- Combined transformer / adaptors
Antigua and Barbuda Electrical Supply
Antigua and Barbuda uses plug types A and B with matching sockets.
The electrical supply voltage is 230 V and the frequency is 60 Hz.
Voltage Converters
Please be aware that whilst a power adaptor will allow you to physically insert a UK plug into a Antigua and Barbudan socket it will not change the voltage or frequency of the local mains supply.
Voltage - The Antigua and Barbudan mains supply is 230 V, which is within the normal UK range of 230 V +10%/-6%, so British appliances are compatible.
Frequency - Antigua and Barbuda operates at 60 Hz, compared with 50 Hz in the UK. Most modern travel electronics are designed to work at either frequency and will be marked 50/60 Hz. However, some appliances containing motors, clocks and other frequency-sensitive equipment may not operate correctly at 60 Hz. Check the frequency rating on your device before use; if it is marked 50/60 Hz, it is suitable for either frequency. If you are unsure, particularly with specialist or medical equipment, check with the manufacturer.
Most modern travel gadgets, chargers and laptops are dual voltage and will work worldwide; check the appliance or power supply for an input such as 100-240 V, 50/60 Hz.
If you have equipment that is not compatible with the Antigua and Barbudan supply voltage, check our transformers page for further information and available options for transformers and power converters that you can use in Antigua and Barbuda. Voltage converters and transformers only change the voltage, not the frequency, of the supply. Changing the frequency requires specialist frequency-conversion equipment, which is not normally practical for travellers.
If you need to take items like hair dryers / straighteners that draw high current then see our hair straighteners page for information on how it can affect your choice of travel adaptor.
Antigua and Barbuda Plug Type Specifications
Plug Type A
NEMA 1-15 class II unearthed, rated at 15A. Commonly found in Central and North America.
The plug has 2 flat blades 1.5mm thick, 15.9 - 18.3 mm long and spaced 12.7mm apart. The neutral blade is 7.9mm wide whilst the live is 6.3mm wide, meaning the plug is polarised and can only be inserted into the socket one way around. Some Japanese plugs have 2 equal width blades, making them unpolarised. Unearthed type A sockets have not been permitted in new buildings across the USA and Canada for many years but they can still be found in older buildings.
Plug Type B
NEMA 5-15 class I earthed, rated at 15A. Commonly found in Central and North America.
The plug has 2 flat blades 1.5mm thick, 15.9 - 18.3 mm long and 6.3mm wide spaced 12.7mm apart. There is also a 4.8mm round or U shaped earth pin which is 3.2mm longer than the 2 blades in order to ensure that the appliance is earthed before the live electrical connection is made. The earth pin is offset from the 2 blades by 11.9mm.
The blades are uninsulated, making them dangerous as a partially pulled out plug can remain connected but the blades are exposed and could be touched, particularly by the fingers of a small child.
