That is what I did at work. I mounted the EVSE at the doorway and used a 25 foot cable. That way I did not have to worry about water damage and the long cord worked well.
2012 Cayenne Red SL traded for:
2013 Pearl White SL Premium
Traded for a Cirrus White 2014 Mercedes B (totaled)
2016 Urano Gray eGolf SEL w/ drive assist
Loved the VW but it sat too low for my old body
Back to a Cirrus White 2017 B250e
