Allows you to use small low wattage American items outside the USA.
Are you going to the UK? If you are then you are also bound to bring back some appliances for your personal use. It is an electrical appliance and as such requires a fuse so as to protect the adapter from any damage due to the overflow or underflow of current. It is small in size and thus can be carried anywhere with ease. It also converts 220 volts as is used in the UK down to 120 volts. It also has a universal socket that takes in a variety of plugs. You can order this online or can get it directly from Sam Stores.
