Good, I would like to know how to lower the voltage of a laptop source, from 26v to 19v?

This type of sources varies the voltage according to the terminal you need and can regulate from 15 to 24 volts, if you want to leave the voltage fixed, follow this link ... greetings http://13norte.blogspot.mx/2011/12/convertir-cargador-de-dos-cables-uno-de.html

I add to what Barbesi replied that this adapter brings the voltage divider of the TL431 into the different plugs, when changing it for HP / Acer / Toshiba / etc you also change the resistors of the splitter and therefore the output voltage. That's why the plug connector that goes to the adapter is 4 pins.

I had a fake interchangeable plug that it brings. The 2 resistors that the plug brought burned, now I have it only with the cables, thanks!

While there would be ways to lower this tension I would not recommend experimenting. You put the life of your machine at stake. regards

If you can, you should see what type of regulator you use in the output if it is TL431 or any other, usually they are configured with a voltage divider and what you have to do is vary that divider to get the voltage you need, but You must be careful with the current. regards
