I would not recommend using the Blink at 30A unless the J1772 plug has been replaced because they may have loose internal connections (see other threads regarding early Blink units). I never had a problem with Blink L2 public units charging the 2011 because it would only draw 18A at 208V. The 2015 will draw 30A at 208V (27A at 240V) and I have had the J1772 connectors get hot on a couple of Blink L2 public units.
I have purchased a half dozen Blink cables on eBay. I soldered the crimp connections. All but one was perfect. The one clearly had problems. It was a real challenge to solder.
Blink set connected EVSE's to 24A to avoid overheating. Originally Leaf's charged at 16A and the Blink units were fine. If you have a Blink unit I recommend changing out the J1772 cable. Tucson EV has 30A cables for $125 and Quick Charge Power has 40A cables in several lengths. A 25ft cable is just over $200 shipped. The Quick Charge cables like the Tesla cables use paired L wires for a very small size. Otherwise the wires are #10 and is good for 32A. The Quick Charge cable uses paired #12 wires. That makes it good for 40A or less.
