I've got 4 largely-independent L2 chargers so I don't ever have to worry about a broken charger leaving me up a creek without a paddle. One Clipper Creek plugged into a NEMA 14-50 outlet that's lasted 12 years so far, another Clipper Creek hardwired on another circuit. If the charger with the plug fails I've got my mobile L2 charger and my old Tesla mobile charger with a J1772 adapter.
For road trips over 150 miles I just use my PHEV. I don't recall the last time I needed to use a public rapid charging station.
