[Shop-talk] shop laptop power source

[eric at megageek.com]

Matt,

I'm no EE (far from it!)  I didn't even sleep in a Holiday Inn last night.
But, it's my understanding that as long as the voltage is a little higher 
(note, not dramatically) it will be OK.

Problems are more likely if the PS produces less voltage than the device 
requires.

But note, it's not my laptop that will be bricked, so YMMV.

On the recommendation of a friend I purchased a universal power supply 
with multiple tips as a backup for several laptops I use in the shop.
The concept is good, based on the tip you select, the power supply 
automatically adjusts the voltage and polarity.

Well my wife is very cautious and asked that I compare the output with her 
factory charger.
Something about not wanting to brick her laptop...

Well, her factory charger puts out 19.5 and the universal shows 20.5

Close enough...   or    close but no cigar?
