Can Tesla be directly plugged into a power source for home charging?

Tesla can be directly plugged into a power source for home charging. Tesla's charging methods: Tesla electric vehicles can be charged at Tesla Superchargers, State Grid charging stations, or by plugging the vehicle into a power source at home. Tesla home charging is suitable for current domestic electricity environments in China, requiring no capacity expansion or separate meter installation, and no equipment modification. Time required for Tesla home charging: Depending on the power of the household socket, it generally takes about 25 hours or 40 hours to fully charge a Tesla from empty. A 220V16A socket charges at 3.52kwh per hour, allowing for 10-18 kilometers of driving, and takes about 25 hours to fully charge from empty. A 220V10A socket charges at 2.2kwh per hour, allowing for 7-10 kilometers of driving, and takes about 40 hours to fully charge from empty.
As a seasoned Tesla owner, I'm quite familiar with home charging. You can plug directly into a standard outlet using the mobile connector adapter that comes with the car. I've installed a 16A industrial socket in my garage - it charges about 200 km overnight, which is enough for daily commuting. But you need to pay attention to circuit load - it's best to have wires in the wall with at least 4 square millimeters cross-section, otherwise the circuit breaker might trip mid-charge. Once I tried cutting corners with a regular power strip, and the plug overheated and deformed - scared me enough to yank it out immediately. Now I keep a fire extinguisher near the socket for peace of mind. If possible, installing a dedicated charging station is the safest option - it can charge most of the battery in just half an hour.
As an electrician, I've installed many Tesla home chargers for clients. You can use a regular power source, but three conditions must be met: first, there must be a ground wire, otherwise the charger will report an error; second, the circuit must be able to handle 16A current, older houses may need rewiring; third, you need to use a high-power socket, like the triangular ones used for air conditioners. I've seen too many people cause circuit breakers by improperly using extension cords, and in severe cases, even melting the sockets. It's best to have the property management check the meter capacity—if it's below 40 amps, an upgrade is needed. If you're doing it yourself, remember to cut the power first—safety comes first. While charging, feel the temperature of the wires—warm is fine, but if it's hot to the touch, you must stop immediately.
