Hi Glen, I have been using the 2nd one that GTB Owl (Geoff) has put up for about 7yrs now, it has been faultless !
I see it delivers only 8amps @ 19V - so not sure how itd go with your lappy requiring 9.5 amps. Might be worth questioning JCar if can or need to ? They may have a bigger one ?
The one thing I considered with lappy purchase for astro was the power draw, seeing I use of a battery bank out leyburn. My Toshiba needs 19v but only draws 3.3amp tho that would equate to about a 6amp draw off the batteries at a 12v output - hense - if your needing 9.5amps @ 19v, then that would draw closer to 15-17 amps off the 12v battery supply !
Something to consider anyway !
All the best with it ...
