Once you know which type of plugs are used in particular regions, you can then start to narrow down your options. Depending on your specific requirements, you can opt for a single-region travel adapter, a multi-region plug, or a universal model.
Single-Region Travel Adapters
Single-region travel adapters are the most straightforward option. As well as particular countries, these models can also be used in countries which all use the same sockets and voltages. However, although these models are usually the cheapest option, it is also worth bearing in mind that choosing a single-region travel adapter may limit future flexibility.
Variations on single-region travel adapters include multi-way models (featuring the ability to plug in multiple devices simultaneously) and the option to pair a one-way single-region adapter with a multi-socket extension lead for multiple devices or increased demand.
Multi-Region Travel Adapters
For greater versatility, you can instead opt for a multi-country or region plug adapter. These are typically slightly larger or more complex units, with different pins for different sockets. Essentially, they are designed to accommodate several national standards of plug and socket arrangements simultaneously.
The most common types of multi-region travel adapters tend to handle a combination of European, Asian, UK, and North American standards. Once again, multi-region versions can be single-way or multi-way to suit your requirements.
Universal Travel Adapters
Universal travel adapters are generally the most flexible option as they are suitable for use in the majority of countries around the world. However, it is worth noting that this flexibility comes with increased size, especially compared to the smaller single or multi-region models.
The added functionality offered by the best universal travel adapter can be a real bonus, but their size can make them less convenient and tricky to transport. It’s also worth noting that in less stable socket types (such as the US two-pin), this added weight can make them feel less securely attached in the socket. Additionally, the larger the universal travel adapter, the greater chance that it may block neighbouring sockets or not fit certain layouts.
