Laptop Power Brick and Cord

[Shyuan]

Hi All,

Thanks for reading this thread. I am facing an issue with the compatible of power cord to my power brick. I got an USA Laptop, but I wanna use this laptop in UK for quite long. I have two options given. Either a "Global to UK" adapter or change my US power cord to UK power cord. Can anyone tell me the below examples will work safely?

1) UK Wall Socket > "Global to UK" plug (MAX 13A 250V~) > US Cord (7A 125V) > Power Brick (Input: 100-240V 2.0A, Output: 19V---6.32A) > Laptop

2) UK Wall Socket > UK Cord (5A 240V) > Power Brick (Input: 100-240V 2.0A, Output: 19V---6.32A) > Laptop

Besides, those sellers told me when I am going to buy a UK Cord (from power brick to wall socket), I should refer to the "Input: 100-240V 2.0A", as long as my power cord is between 100-240V and Amp should be same or higher than 2.0A then the power cord is safe to be used, is this true?

Your help would be much appreciated! Thanks

The problem of adapting between AC wall voltages in different countries used to be much greater with linear power supplies that are typically specified for U.S. (118 VAC), Europe (230 - 240 VAC), Japan (100 VAC), etc. Most contemporary electronics, including your laptop, use universal switching power supplies that can accept a wide range of input voltags from 100 - 240 VAC.

The standard AC wall voltage in the UK is 230 volts, which is within that range so all you need is an AC power cable that plugs into your power supply on one end and British standard AC wall connection on the other.

If you can't find a British AC cable that plugs into your power supply, all you need is an inexpensive adapter between your U.S. wall plug and British AC sockets like this one that adapts between connectors without converting voltages.
