You will get a far better selection looking online, and depending on your charging needs you might spend less as well. There are many EVSE's (which I think is what you mean by "docking station") which are outdoor rated. Brands include:
AeroVironment (Nissan's "official" charging solution, available with and without Nissan branding)
Clipper Creek
Siemens
Leviton
Legrand
Bosch PowerMax
Blink
The GE Wattstations have had issues with the Leaf on-board charger before. I don't know if that has ever been addressed via a software update.
