Charging in the rain & securing the L1 charger

A couple of points. So near the factory where i work some kind individual broke into a civic to steal an antique GPS.
That individual would have been better off with my L1 charger. Judging from ebay and dealer prices, that's quite an expensive apparatus.

The rainy season has started in Seattle. For the reasons above i decided to try keeping the charger inside the trunk. I really wish there was an inside-the-trunk charging plug, but there is none. So i tried the 15A extender cord and the L1 charger. I did not lock the rear door initially. But one day it did lock itself in. Not completely, of course, but just enough to be locked and not be opened without the remote.

Disclaimer: don't do it. I do understand that i'm violating Mitsubishi's rule of not using cord extenders and also risking damaging both cables, or risking overheating. Familiarize yourself with physics and rules of conductor resistance & how it affects heating. Also inspect the cables if you chose to use this method of securing the charger. Be gentle with the door.
