There are two basic types of travel adaptors: universal and country-specific.

Using a travel adaptor is an important accessory for travellers who want to power their electronics on the road. While many devices can be charged from a mains outlet, some have a higher voltage and need special adapters to operate.
There are two basic types of travel adaptors: universal and country-specific. The latter is better for frequent travelers, who may need to use an adaptor in several countries.
A universal adaptor works in most countries. It is able to accommodate a range of plugs, including UK, European and American. These adaptors can also be used to charge your USB devices. Some of the adaptors have an in-built fuse and surge protection, which is essential in countries with unstable power.
When you buy a travel adaptor, make sure it is CE marked. This is a mark that indicates that the product meets safety standards. However, some substandard products incorrectly use this mark, which could constitute an offence under the Trade Descriptions Act 1968.
A country-specific travel adaptor allows you to use your British three pole earthed plugs in most sockets in another country. You can find these adaptors at big international airports. A single adaptor can be bought for a single country, or you can buy a four-in-one that offers four different adaptors in different colours to suit different regions.
A USB travel adapter has multiple USB ports, allowing you to charge up to four devices at once. You should choose one that has enough overall output to cover the voltage needed by all your devices.
