I made this up last year to power my Dell Inspiron 1520 laptop from 12v portable power, but now have no need for it since my dark sky site now has 240v in the field.
It cost me about $100 for the parts:
- DC converter from JayCar (12v to 18-20v, part#120-003)
- lead/plug to suit Dell 7.4mm socket from
www.laptopjacks.com.
Sell for $70 including postage within Aust.
Please send a PM if interested.
Cheers,
Jeff
