Laptop Power Supply to Power PL6
I've read between the threads that a laptop power supply can be used to power a PL6. I don't need huge amounts of power since I'll only be charging a 1S and a 3S Lipo. I would like to use it mostly for home use or emergencies since I have access to a buddys 24V at the field.
What are the minimum requirements a laptop power supply should have to power this PL6?
I have an old spare one rated at:
INPUT: 100-240 V
OUTPUT: 19V - 6.3A - Would this PS work?
I am comfortable soldering so I can mod the connector.
Thanks in advanced.

A 3S LiPoly (12.6 charged voltage) requires 12.6 X 1A = 12.6 watts per 1,000 mAh for a 1C charge.
The aprox. 100 watts available wold charge a 3S at up to aprox. 8Amps.
100 / 12.6 = 7.9 Amps.
There is an excellent charging capability spread sheet posted. on the Revolectrix site.
Tim or someone how about updating the link in the first post of PowerLab8 introduction thread?
