If you are electrical savvy, perhaps the previous chart is all you need. If this is not the case, you can continue reading and discover what the chart is saying!
Plugs and Sockets at each country
In United Kingdom the following plugs are used: (includes London, Bath, Oxford, Cambridge, Brighton.)
|Plug Type G||Plug Type D||Plug Type M|
|Outlet Type G||Outlet Type D||Outlet Type M|
Considerations for the United Kingdom
It is likely you will only find plugs-type "G" in the UK. Plugs type "D" and "M" are considered "old" and not common. They are are still used nowadays to differentiate low-power lighting circuits. So please don't try to use an adapter on them for high-power equipments like hair-dryer or even battery chargers.
We keep "D" and "M" plugs in our database as we don't know your exact destination and you might find one next to a bed table. As a rule of thumb, you will probably be fine with the type "G" in hotels and big cities.
... and in Guam you will use: (includes Hagåtña, Dededo.)
|Plug Type A||Plug Type B|
|Outlet Type A||Outlet Type B|
Take care: Guam uses lower voltage than United Kingdom
Your electric devices from United Kingdom will be expecting 230 Volts, but Guam grid is of 110 Volts, this is a substantial difference that requires you to take some extra steps in preparation to your trip:
On the positive side, nowadays many devices will switch automatically to the network voltage and they will work just fine, i.e. mobile phone chargers are typically multi-voltage (but please, do actually check your own). It is important that you pay attention to your device's voltage. Connecting electronics to the wrong voltage, in the luckiest of the cases, the device will break or stop working temporarily; but please don't take this lightly, in the worst of the cases electrocution and fire hazards are a real possibility.
An automatic power supply suitable from 100 Volts to 240 Volts.
High-power devices don't usually handle different voltages due to the high-currents involved i.e. anything that its main purpose involves generating heat (or cold) like hair driers, baby bottle warmers, kettles, etc. On the contrary, modern low-power devices are likely to auto-detect and auto-adapt to different voltages i.e. usb chargers, laptop chargers, etc.
A hair-dryer can consume up to 2000 Watts, like the one in the picture above, due to the high power they usually work in one voltage system; this one is suitable for 220-240 Volts systems.
You will need a step down voltage converter a device that can be plugged to 110 volts and it provides an outlet with 230 volts for your United Kingdom' device. You will need to pay attention to the maximum power output of the converter and the maximum power consumption of the device.

No equal Hertz
This is not a big issue. Unless you are using an electric alarm clock or some motors when speed is an issue. Explanation: Some alarm clocks uses the frequency of electricity network to measure time. So, time shifts could be experimented. Almost every home electronic device works perfectly with different Hertz.
