I used the CCS charger at Del Chevy in Paoli PA, it's probably a 24 kw/hr as my Bolt was showing a little over 20 kw as it charged.
The charger is outside and available 24/7 and is non-networked, you just plug-in and hit the start button.
Unfortunately, it's located right where the service technicians have cars pull-in for an initial service evaluation, one tech at the service desk told me charging was no problem, but another asked me to move my car just a few minutes after I started charging.
I applaud GM / Chevy for developing the Bolt, but I just don't understand why they fail to see the potential in having EVERY dealer install an accessible CCS charger. Chargepoint is the official GM network, and it would certainly help with sales if a potential buyer knew that they could use chargers at every dealership through the Chargepoint network. That's over 4,000 dealerships.
