On a daily basis, the car is charged while parked in the garage. I hired an electrician to bring a dedicated 220-volt line into the garage. Tesla supplies a High Power Connector and charge cable with the car. The first unit they supplied had an issue with the smoke detector. The second unit was installed without the smoke detector, as it was not required. My house already has seven smoke detectors! With the 220 Volt connection and 70 amps, the Roadster will charge an empty battery in only 4 hours.
A charge cable connects the High Power Connector with the car. The charge cable resembles the cable at a gas station in size but actually feels even heavier.
The charge port on the car is on the left hand side; Tesla chose the left hand side so you would not accidentally drive away with the plug in the car. The charge port also resembles your gas tank in a traditional car. Tesla recommends the charge cable connected to the car whenever the vehicle is parked.
