Wallbox

A wallbox is the charger you mount in a garage or driveway: a dedicated AC charging unit wired into the house supply. The US Department of Energy says a qualified electrician can add the circuit it needs, and recommends safety-certified equipment. It is faster than a household socket: the Department estimates about 25 miles of range per hour on Level 2 against about 5 on Level 1. In the US, most residential Level 2 units operate at up to 30 amps, which delivers 7.2 kW; the Australian Government describes dedicated home chargers as 7 to 22 kW.

Strictly, the wallbox is the delivery hardware. The AC-to-DC conversion happens in the car's onboard charger, so the slower of the two sets your real speed. Check whether a model can schedule charging to match your tariff.

For total cost of ownership, home charging is the lever. The EPA says charging a plug-in vehicle is typically cheaper than filling a gas tank, but depends on local prices. A wallbox plus an off-peak tariff may lower energy cost per kilometer, while relying on public DC fast charging alone, which the Australian Government says typically costs more than Level 2, erodes that advantage.
