I am looking for a power solution for my Laptop whilst camping. I was thinking of an inverter but after researching the subject it seems more efficient to just use a converter from 12V to 19V.
I have found many devices that will convert from 12V to 19V but my laptop powerpack supplies 19V - 4.74 A (90W Max) to the laptop. The converters i've looked at supply 19V - 3.5A. Is the amp diference going to be an issue? How close to the 4.74A do I need to be?
