I personally have a 32A JuiceBox installed outside my garage. It has been through several Syracuse winters which sound similar to your climate (typically teens to 20s in mid winter but occasionally dropping below zero, to -20 or so. Lots of snow!)
The JuiceBox is plugged into a NEMA 14-50 outlet and exposed to all weather. It still works great - I’ve had no problems with it.

I second this although I live in Maryland. Got our Juicebox installed March 2021 and had zero problems. Sometime we charge in the garage sometimes out. No problems charging in all types of weather.
I really like the plug-in factor since in theory we can take the charger with us, if we ever travel to a ‘far off land.’ As long as they have the NEMA 14-50 outlet we are good to go.
