[C36IA] Deck Light

Tue Jun 23 17:57:48 EDT 2009

I have a jump start battery I bought 3 or 4 years ago at Sam's Club.   
It is called "Power on Board" and is no longer sold there.  I believe it 
was made by Vector.  I am told that their current models are not as 
powerful as the one I have, but have not compared them myself.  have 
number of older cars in the family and have used it often.   I think to 
buy a new one I would get one of these - 
http://www.asedeals.com/jumpstarters2.html      Amazon also carries Jump 
N Carry.
