EDIT: $100 + actual shipping

New, only plugged in to test it. $160 new on Amazon.

Dont forget to connect it to the Tesla plug and wait 30-45 seconds before you plug in to your car, per the instructions from Lectron.

Works with Destination Charger and Mobile Charger, not Superchargers. Some Destination Chargers are known to need a switch flipped inside to allow charging, but I've had great luck with these over the last couple of years.
