Some connected product functions might not be available. ** We call the NJORD® GO an ‘EV charger’ but technically speaking, it’s ‘Electrical Vehicle Supply Equipment’ (EVSE) that provides a safe supply of electricity to power the on-board battery charger in your EV. Most people use the term ‘EV charger’ so to keep things simple, we’re going to use this term as well.
