[aprssig] Power For a Lap Top

[Ron]

Just wondering of any precaution when operating a Lap Top (Compaq Armada 
3500) from a 12 VDC to 110 VAC inverter.  I heard of a case where someone 
tried a cell phone charger only to fry the power supply.  I question that 
since the cell PS is low current draw and not much iron in the transformer 
that spikes may have played a roll in this accident or may be it was just 
that time for the transformer to go?  Thanks for your thoughts.
