laptop in England

I did a quick search and couldn't find anything.
I might be taking my laptop to London this summer. If I do, can I use one of these:

to plug in the power cord?

 

I can't see the product from the link but you'll just need an adaptor to the standard UK 3-pin plug.

 

ok so even though Europe / USA don't have the same amount of power from outlets, just an adapter will be fine and won't fry my power cord? Just want to triple check. Thanks

 

Look at the power adapter on your laptop. Most likely it says "input voltage 110-240VAC" (or 110-220 or whatever). If it says that, then all you need is an adapter to change the 3-pin UK style to your US style plug.

If your laptop says input power 100-120VAC or 110VAC or something (i.e. doesn't go up to 220-240) then you need an actual power converter with a wattage rating higher than your laptop power adapter draws.

99% of laptops these days have a power adapter that will run fine on 220, but check first, or you'll let the smoke out of it.

 

Yes, good idea. Just make sure of that. (I don't want to get sued. )

 

Thanks Mike and Gemm, very helpful

 

I was in the UK last year. I checked my power cord before hand and it was within specs and worked fine with just an adapter as did the majority of my higher end electronics.

Just be careful of any lower end stuff and if in doubt use a converter. Had a hair curler melt and nearly catch fire. (rolling eyes)
