The Christiana Mall now has ten J1772 L2 charging stations. They are free and have a 2 hr limit. They are end parking spots closest to the stores located from Barnes & Noble down to Nordstrom's. They are Volta charging stations. Volta has an app that tells you how many stations in each cluster are in use. I didn't have my Tesla to see what speed they are. Volta's FAQ page says their L2 charging stations are 20A-40A.
