| Why are most laptop computer batteries around 10.8 volt DC but most laptop battery chargers are putting out 19 volt DC ? |

Yes but it will charge slower. We have a couple of Dell laptops and one of the chargers is a lower voltage and takes longer to charge completely. Ok good deal. I have an old laptop without a charger, so I made up a cord with an automotive cigarette plug. Going to plug it into the truck and see if I can get it to charge. |

Be careful, the power from a cigarette lighter outlet in a vehicle is going to be very dirty. If you're going to do that, I would recommend charging it with the laptop off. You might still kill the charging circuit, and I recommend leaving the truck idling while you're doing that. Revving the engine will result in voltage spikes that could kill the laptop. A standard benchtop power supply would be a better choice, while a replacement generic power supply would be the best choice. |

The power brick most laptops come with is actually a global product. They just include the right wall plug for the end users country. Read the fine print on the brick some time.  Power bricks use a switching power supply. Anything from ~90VAC to ~250VAC input will give the same output voltage and current. |
