You're lucky, it's not a good holiday for Mick unless he comes back with at least a couple of new drills or other assorted tools and 2 or 3 pairs of steel toe-cap trainers! Like I said though because he has the 110v transformers he can buy any of them and use them here.

I took a hairdryer out to orlando one time, which apparently didnt like the conversion! It was quicker for me to get someone to blow on my hair!!!
My mobile phone charger was very slective with which plugs it would work in or not!!

Electronics and motors work differently. A hairdryer will work at half speed because the motor makes half as strong a magnetic field at half the voltage (the heater will also be anemic). You have to wind the motor differently to produce the same resulting speed. The power adaptors in sophisticated electronics have a circuit that varies the current with the voltage...producing the same net output. Remember, your computer only runs at somewhere around 18 volts anyway..so going from 240 to 18 or 120 to 18 is still a big step down.
Here is a cut and paste from the Dell Website for one of their notebook pc's:
AC Adapter:
Input voltage: 90 to 135 VAC and 164 to 264 VAC
Input current (maximum): 1.5A
Output current: 4.5A max. at 4-second pulse, 3.5A continuous
Output power: 70 W
So the battery sees 70Watts coming at it no matter what the input voltage. It's the input current that varies.

Not being technically minded <img src=icon_smile_blush.gif border=0 align=middle> perhaps you can tell me why a UK hairdryer used with an adaptor works at half speed in the US and my batteries that usually charge up in an hour or so take double the time?? I just assumed it was because they only receive half the "juice" they needed <img src=icon_smile_blush.gif border=0 align=middle>

Thanks MMFAN - I think I understand now - it's something that's puzzled me for years!
