I just ordered my Model 3 today, and I’m very excited! I drive about 40,000 miles/year, and I’m planning on getting about 60% of those miles from chargers at work, which are only slightly protected from the elements, including Michigan winters. What are people’s experiences with heavy use of the J1772 adapter? Is it pretty durable? Should I pop for a spare adapter, especially since the nearest Tesla store will be over three hours away? Thanks in advance!
