Electrical Power for Laptops
That's about 80-watts but the efficiency of the laptop's power supply (transformer) is less than 100%, so the laptop would actually use considerably less power if you could bypass the 220-V AC power input and run it directly on DC with a high capacity external battery. A point of reference: I have a 75 watt inverter that seems to have no problem running my Laptop... jon
