Mercury Adaptors

Mercury adaptors here add outlets or USB charging to a UK socket, let plugs work across UK, European and USA sockets, and join leads with different connectors. Examples include 2, 3 and 4 way mains adaptors, a shaver adaptor, travel adaptors for Europe and the USA, a world to UK adaptor, a caravan trailing socket on a Ceeform plug, and IEC plug adaptors for figure 8 and cloverleaf devices.

Choosing Mercury Adaptors

Start with the socket you will plug into and the plug you need to connect, then check the rating.

The 429.819UK is a plug-in 4 way mains adaptor with surge and spike protection, separate colour coded on/off switches and neon indicators. The 429.690UK plugs through an existing 13A socket and adds two USB ports sharing 2400mA, and for an electric shaver the 429.824UK adaptor is fitted with a 1A fuse.

Travel adaptors

Frequently asked questions

What does a plug adaptor do?

A plug adaptor lets a plug connect to a socket it would not otherwise fit, or lets more than one device run from a single socket. The 3 way 429.813UK powers three devices from one UK mains socket and is fused at 13A, while the 2 way 429.817UK is unfused; both conform to BS1363/3. The 429.824UK shaver adaptor lets an electric shaver run from a UK mains outlet, with a 1A fuse to BS646.

Which travel plug adaptor do I need?

You need one that takes your plug and fits the sockets where you are going, rated for the load of the device you will use. The 429.905UK lets a UK 3 pin plug fit a European Schuko socket and is rated 10A and 2300W, and the 429.910UK adds twin USB ports sharing 2400mA. For the USA, the 429.787UK is rated 10A and 1100W. Going the other way, the 429.832UK takes plugs from several countries into a UK outlet.

Will a UK appliance work in the USA with the travel adaptor?

Yes, if the appliance is compatible with the local USA voltage, because a socket adaptor lets the plug fit the socket but does not convert the voltage. The Mercury 429.787UK lets a UK mains plug connect to a USA socket and is rated 10A, with a maximum load of 1100W. Check the device's voltage rating before using it in the USA.

How do I use a foreign plug in a UK socket?

Fit it into a plug-in adaptor that takes the foreign plug and plugs into a UK outlet. The 429.829UK takes a European Schuko plug and is fused at 13A, and the 429.832UK accepts plugs from Germany, France, Italy, the USA, Australia, New Zealand and China, also fused at 13A. The 429.832UK does not earth side contact earth plugs.

What is a travel adaptor?

A travel adaptor lets a plug from one country fit the mains socket of another. The 429.905UK takes a standard UK 3 pin plug into a European Schuko socket, and the 429.787UK lets UK mains plugs connect to USA sockets. Going the other way, the 429.829UK connects equipment with a European Schuko plug to UK mains outlets. The 429.787UK is a socket adaptor only, so check the device suits the local voltage.
