Answer» Hey, I have some vistors from overseas who happend to bring a laptop with them but forgot to buy an adapter for their electronics since where they come from they use 220V while where I live it is 110V.

Hey,
I have some vistors from overseas who happend to bring a laptop with them but forgot to buy an adapter for their electronics since where they come from they use 220V while where I live it is 110V. However their laptop is exactly the same as mine (with the exception of theirs running on 220V), and I looked at the BATTERIES of both laptops and I dont see a difference. Infact i am able to plug in the battery of 1 of the laptops into the other (i didnt turn the power on). so My question is Can I charge their battery on MY laptop? or can I use my battery on their laptop. it is somewhat urgent and we need to get some files from their laptop

Also if I do have to buy a VOLTAGE CONVERTER, which one do I need to buy to be able to charge thier laptop's battery (is 2000 W sufficient?)

Thanksi believe the only difference between the two computers is the size of the transformer in the charger itself. if they brought their charger, compare its output to yours (the chargers should clearly say the output voltage (V, VDC, or Volts), output AMPERAGE(A or Amps), output frequency (Hz), and/or output wattage(W or Watts)). if the outputs match EXACTLY, then you can use your charger in their comp.

if the outputs of the chargers do not match and you have to buy a converter, then read the input of the 220V charger. it should say how many amps it consumes. multiply the number of amps the charger consumes with the voltage to get the wattage.

example:lets say your charger consumes 5Amps @ 120V (i dont know where you live but in north america 120V is the standard voltage)

P=I*V
P=5*120
P=600W

in this case the 2000W converter will be more then enough.There may be an even more simple solution to this. Check their power SUPPLY. Most modern laptop power supplies (adapters) are designed to take any input (100-220v) and cut it down to what the laptop needs.
