To answer this question a voltage is needed. Amps = Watts/Volts.
none
It depends what you mean by 'power lead' If you mean JUST the flex from the mains to the power adapter, cost is around £8.00 - However - if you mean to replace the whole power supply, it could be as much as £30 depending on the make & model.
Mains supply provides alternative current while battery provides direct current.
A CRT monitor is much heavier and is a lot bigger front to back. It connects directly to a mains electricity supply and is power hungry. When it it working, getting close to screen will make the hairs on the back of your hand stand up. A LCD monitor of the same viewing size is lighter and physically flatter front to back. It often has an external power supply and uses much less power.

My mobile phone (an Alcatel) charger will supply 500 mA at 5 V. So the maximum continuous power it is capable of supplying will be the product of these two -i.e. 2.5 W. Of course, it won't necessarily ever reach that value in practise.
The 2010 Dodge Charger SRT8 has 425 horsepower. The normal Dodge Charger that isn't supercharged will have a 368 horsepower engine.
Ask your local mains electricity power supply company to install a 63 Amp 3-phase supply at your site. It is not something you can buy in a shop like a battery. It is an electricity supply service that is different to a standard domestic home mains supply but is quite normal for places which use machinery such as workshops, factories, etc.
The charger that comes w/ the Droid X is 850mA and a blackberry charger is 700mA. You can use your blackberry charger, but it's probably not the best idea since it's not putting out as much power.
SMPS: Switch Mode Power Supply - specifically refers to switch mode power supplies which are supposed to be more efficient by using a much higher frequency than mains on the primary winding of the transformer. Charger could refer to either a SMPS or a conventional transformer which operates at mains frequency. For charging batteries outside of the laptop, both will have extra circuitry.A2Switched Mode Power Supplies, do not use transformers to change the voltage. This makes them lighter and more efficient.They chop up the rectified mains into small pulses and then charge a capacitor. This is all controlled precisely by electronics. Altering the pulse width can control the current demand and regulate the output voltage.When they are off load (battery charged and computer off) they draw minimum current from the mains. As the load varies, a smps can cope with changing current and yet keep the voltage accurately within specification.Laptop chargers use this process instead of a transformer. This keeps the weight and bulk down. A transformer capable of handling 4 to 6 amps at 20volts would be very heavy, bulky and more expensive.
