Computers and laptops
You should be able to use your 110 volts laptop in Britain without any problems as nowadays most run on both 110 volts (as found in North America), and on 220 volts (as found in Europe). Although the voltage is universal, you will still need an adapter to plug your computer into an electrical outlet.
