L702X Overseas Power

If I will be using an L702X out of the US , for an extended time , connected to the electricity ( and not Battery ) . Is there any disadvantage in using a power converter with the US power adapter , as opposed to replacing the US power adapter with a local one ?

 

Power adapters are multivoltage (110-230V), so you can just plug it in...if you use it with an adapter would be practicability...you can get however a cable for the local socket for your adapter, as adapters are the same world wide, just the cable is different.

 

Yeah, all countries use the same power bricks with different brick-to-wall cables. Just make sure you use a surge protector, especially if you're in a locale with "dirtier" power than most of the US.

 

Thanks Razor2 and Commander Wolf - wow - I was never aware of this - it's just the cable which is different . So , to re-phrase , if I get a local cable , or use the original one with a converter - no difference ?
I was under the impression that the power adapter/brick has surge protection itself - not so ?

 

Power adapters have some protection, which is enough in countries like the EU or US but you might need some better stuff if you want to use the notebook in countries with weak power grids...ie. some parts of the Middle-East, Africa, some parts of South-East Asia.

 

Thanks Razor2 .

 

You do not need a different cable. Just get an inexpensive plug adapter. It will have female receptable-like socket into which you plug your US plug, and the other end will be the pin configuration of your desired country. This should cost maybe $3-$4.

 

Thanks Toronto - I call that a converter . You're saying that is just the same as using a local cable ?

 

No, a converter is different. A converter is a heavier, more expensive item that transforms power from one voltage to another. Since laptop power supplies already accept a normal range of power (~ 110 volt to 220 volt), you don't need the expense and weight of a converter/transformer.

All you need is a plug adapter, such as this:


They are quite cheap. They do not convert power, they just allow your North American plug to be connected at one end, but the end that plugs into the wall socket has the pin configuration for the country you're visiting.

 

Thanks Toronto - nice pic - can't get clearer than that .
The laptop supply is not aligned to 110 or 220 volts ? It will just automatically "adapt" itself to whichever of those 2 you connect it to ?

 

If you read the text on the rear of the power adapter, you'll likely see it says something like "Input: 100 - 240v". That means it accepts 100 volts, 240 volts, and anything in between.

 

OK , I understand , thanks Toronto .
