Level 1 uses a standard 120V outlet — works out of the box, charges 3–5 miles per hour. Level 2 needs a 240V circuit and adds 20–35 miles per hour. For most drivers covering more than 8,000 miles/year, Level 2 is worth it.
Charger hardware
$300–$800 for a quality residential Level 2 unit (Wallbox, JuiceBox, ChargePoint Home Flex, Emporia, Tesla Wall Connector). Smart-charging features matter for time-of-use rates.
Installation cost
Typical hardwired install: $400–$1,500 if your panel has capacity and the run is short. Add $200–$600 if the panel is far from the parking spot. Panel upgrades from 100A to 200A run $1,500–$4,000.
Federal credit (Section 30C)
30% of the cost of qualified charging equipment plus installation, up to $1,000 for residential property. Address must be in an eligible census tract — most non-urban areas qualify.
Utility rebates
Many utilities offer $250–$1,000 rebates for residential Level 2 install. Check your state guide for utility-specific programs.
