Buying a used electric vehicle is one of the smartest financial decisions you can make. A 2-3 year old EV offers incredible value, but many come without a charger or include only a basic Level 1 unit. Choosing the right home charging solution maximizes your savings and convenience.
Why Used EV Owners Need a Quality Charger
A 7kW home charger adds 25-30 miles of range per hour — a full charge every morning. Home charging costs 3-5x less than public DC fast charging. With a used EV's lower purchase price and cheap home charging, your per-mile cost is minimal.
