For those not familiar with the equipment in the left photo, The blue part is a CHAdeMO handle. It is plugged into a CHAdeMO-to-Tesla adapter. The black bands surrounding both pieces is a means to prevent (?) the CHAdeMO adapter from walking away, since they used to retail for around $500 each. The end of the CHAdeMO adapter is a standard Tesla Proprietary Connector which plugs into our Teslas.
I'm not sure how that contraption can be used by a CHAdeMO vehicle like a Nissan LEAF.
