battery charging

[Mark Trank]

Have any listers ever used a battery starter that connects via cigar/rette
lighters?  I have been called upon a few too many times to jump start a
stranded motorist and its a huge hassle to access the battery in the 200q's
back seat (requisite Audi content) in order to do the right thing and assist
someone.  Last time I had to do this, it was pouring rain, child car seat
had to be pulled out of the rear seats, etc.  Not fun.  Direct mail outfit
based here in town advertises a device called an "easy-start jump starter"
that claims to allow you to jump start your car through the lighter sockets.
You plug the device into the "donor" car, then into the "dead" car, wait
five minutes and start the engine.  An LED display is said to confirm
correct connection and charging.  Cost is about $30.00.  Don't know whether
the premium is worth it or not.   

Advice is appreciated, as always.

TIA,
