[Lancaster] Re: Laptop supply from 12v DC

[Ken Hough]

Max,

Since last posting on this subject, I've bought a 12v to laptop supply 
converter from Maplin. This is Stock code number L40BB. Cost £32.49 incl 
P&P. It's a 120W unit. A neat unit which works well to allow use of my 
IBM Thinkpad T21 via the car battery.

The reason for this stems from my budding interest in astronomy and need 
to use the laptop outdoors, but usually with the car at hand. During 
cold nights (like now) I discovered that the laptop will run for maybe 
only 1/4 of an hour. At room temerature it will operate for > 2hours so 
battery seems OK.
