Please don't explode computer.

US visiting UK, do I need an adapter or a converter for my laptop?

I just want to double check because I'd really rather not have my laptop explode when I visit the UK next month. The AC adapter for my laptop gives the following specs:

65W, 20V
INPUT: 100-240V~1.5A 50/60Hz
OUTPUT: 20V . . . 3.25A

My understanding is that I would only need an adapter for the plug and not a power converter. Am I correct? Thanks for the help.

Yes, you're right.

That is correct.

This is what you need.

Adapter, definitely. Pop into Radio Shack (or wherever), or wait until you arrive and you can buy one in a tourist shop pretty much anywhere (for an inflated price).

Actually, the price at the airport in Philly was better than Radio Shack's for a converter.

This is what you need.

If going to the UK, sepsis would be better off with this - UK plugs aren't compatible with those used in mainland Europe.

If you're staying in a decent hotel, they should give you an adapter to use.

Yes, my bad, Mike1024, I didn't look at the pin-end of the plug.

If your AC adapter comes in 2 parts (the cord that goes from the laptop and is connected to a small box, then another cord that plugs into that box and into the wall) you can purchase the UK equivalent of that second cord (such as this or this).
I have found that the sort of adapters linked above work just fine, except that often (if your device uses a 2-prong plug like an American device) the connection isn't very secure and it can be knocked loose by a strong wind. Not such a big deal if your laptop battery holds a charge and you occasionally glance to make sure it's still getting power from the wall.

What K.P. said -- for two-part adapters with a standard IEC connector (which includes Apple adapters, too) you can usually get the equivalent with a UK plug. Maplins in the UK will provide.

Best answer: Yes, and just to add some info, the 100-240V is the range that the box in the line from the laptop to the outlet can convert voltages from, so it can accept any voltage in that range. I used my laptop in the UK with the adapter listed above and there were no problems. Have fun!

Yeah, cheap-o adapter to UK style plugs and don't count on British hotels having *anything* when you want it ;-)
