2003 Boxster S and trickle charget

I run it between the windshield and the frunk. Attach directly to the battery, then close the hood and plug into an electric socket. Done.

+1 ditto on direct connection to the battery. I use my Schumacher charges all my vehicles if they are not being driven for more than a few days.

I have been using my Porsche Maintainer battery charger anytime I won't be driving it for 3 days or more for the last 18 years. it plugs into the lighter socket.
