The Tesla Model S is one of the most popular electric vehicles, impressing with its technology, environmental friendliness and efficiency. But it's important to know how to charge your car properly, especially if you plan to use a regular outlet. In this article, we'll take a closer look at all aspects of charging a Tesla Model S at home, including the use of a mobile connector, ECOFACTOR chargers, and power outlets.
We would like to remind you that you can purchase charging stations for home and business in our online storeas well as charging at our public stations ECOFACTORlocations across the country. For convenience, use our mobile application, available for iOS and Android.

Why you should charge your Tesla Model S at home
Charging at home is the most convenient and cost-effective way to keep your Tesla Model S battery charged. The benefits of home charging are obvious:
- Accessibility: Every home has a standard 220 V socket.
- Cost-effectiveness: Nighttime electricity tariffs reduce costs.
- Convenience: The ability to charge the car at any convenient time, for example, at night.
However, it is important to know the features of the different charging options so that you can choose the best method for you.
Tesla Mobile Connector: the key to basic charging
Tesla equips its cars with a mobile connector, which is an integral part of the basic charging kit. This device allows you to connect your car to a standard 220V household outlet, providing basic charging functionality without the additional cost of installing special equipment.
How does the mobile connector work?
The Mobile Connector is a charger that combines the functions of an adapter and a charging controller. It automatically regulates the current to ensure a safe and stable power supply. The connector plugs into a standard wall outlet and converts AC power to DC power to charge the vehicle battery.
The convenience of the mobile connector lies in its portability: you can take it with you when travelling and charge your car anywhere with access to the power grid.
Grounding: a must
One of the key requirements for using a mobile connector is that the socket is earthed. This is a critical factor that ensures:
- Protection against static electricity. During charging, the vehicle can build up static charge, which can be dangerous if not properly earthed.
- Stability of work. Grounding reduces the risk of power surges that could damage the charger or the mains supply.
- Security. Grounding prevents short circuits, reducing the risk of fire or other emergencies.
What should you do if your outlet does not have a ground connection?
The absence of a ground connection in the outlet does not mean that charging is not possible. There are alternative solutions:
- Third-party chargers. For example, ECOFACTOR devices, which are equipped with additional functions for operation in ungrounded conditions.
- Installing the correct socket. For long-term use of the Tesla, it is recommended that you contact an electrician to install a special grounded outlet.

Charging from a regular outlet: advantages and disadvantages
Advantages:
- Accessibility. A standard 220V socket is available in almost every home or office. This makes charging as easy and affordable as possible.
- Ease of use. Charging via the mobile connector requires no special technical knowledge. It takes just minutes to connect the vehicle.
- Cost-effectiveness. Charging from a household outlet can be cost-effective, especially if your region has nighttime electricity rates.
Disadvantages:
- Slow charging. A standard socket has a limited power output of about 3.5 kW, which affects the charging speed. For example, for a 75 kWh battery, it can take 10-12 hours to charge the 50%.
- Dependence on the state of the network. Older or worn-out power grids may not be able to withstand prolonged loads, resulting in charging interruptions or equipment damage.
- The risk of overloading. Using a household outlet together with other powerful electrical appliances can overload the mains.
Optimising the charging process
Despite the drawbacks, charging via a standard outlet remains a convenient solution for most Tesla drivers. To maximise the effect, it is important to consider a few recommendations:
- Charge it at night. This is not only cost-effective, but also reduces the load on the power grid.
- Check the outlet before use. The socket and cables must be in perfect condition to avoid overheating or short circuits.
- Consider the power outlets. If you charge your car frequently, installing a red three-phase or blue single-phase socket will significantly reduce charging time.
Tesla Model S plug-in charging is a convenient and simple solution for everyday use that meets most of the basic needs of drivers. If you need advice on the choice of equipment, please contact ECOFACTOR - we are always ready to help make your charging more efficient and safe.
Using power sockets: speeding up the charging process for Tesla Model S
Power Sockets are the ideal solution for Tesla Model S owners who want to reduce the charging time of their vehicle. With a higher power rating than standard household outlets, they allow for a much faster replenishment of the battery's energy, while ensuring a stable and safe process.
Red socket (three-phase): maximum efficiency for European models
The red three-phase socket is the best option for European Tesla models that support three-phase charging. This solution allows you to get the maximum charging speed, which is especially important for owners of cars with high mileage or those who often make long journeys.
Features of the red socket:
- Power up to 22 kW. This enables significantly faster charging compared to a standard 220V socket. For a 75 kWh battery, the 80% takes only 4-5 hours to charge.
- Compatible with European Teslas. Most European models support three-phase charging, which allows you to take full advantage of the power of a red outlet.
- The need for professional installation. For the socket to work properly, it requires the advice and installation of an experienced electrician to ensure that it is properly connected, earthed and complies with safety standards.
The advantages of a red outlet:
- Charging speed. The three-phase current significantly reduces the battery recharge time, which is important for those who use their car every day.
- Efficiency. Charging takes place with minimal energy losses, which increases the overall efficiency of the process.
- Convenient for long journeys: Thanks to the high power output, you can quickly recharge the battery when stopped at home or in the garage.
Disadvantages:
- Suitable for European models only. American Teslas do not support three-phase current.
- Installation cost. The need for professional installation can increase the initial cost.
Blue socket (single-phase): the best choice for American Teslas
The blue single-phase socket is the ideal solution for owners of American Tesla models that only support single-phase current. It provides stable charging with a power of up to 7.4 kW.
Features of the blue socket:
- Power up to 7.4 kW. It takes about 8-10 hours to charge the 75 kWh battery of the 80%.
- Easy installation. The single-phase socket does not require complex installation and additional settings, making it easier to use.
- Compatible with American Teslas. This type of socket provides optimal charging conditions without the need for adapters or adapters.
The advantages of a blue outlet:
- Accessibility. Easily integrated into domestic or commercial power grids.
- Compatibility. Fully meets the technical requirements of American Tesla models.
- Cost-effectiveness. Reduces equipment and installation costs.
Disadvantages:
- Lower charging power. Compared to a three-phase red socket, a blue socket takes longer to recharge the battery.
- Limited functionality for European models. For Teslas that support three-phase current, the blue socket does not use the full potential of the charger.

Charging the American Tesla from a three-phase red socket
The question often arises: can an American Tesla be connected to a three-phase red outlet? The answer is yes, but there are nuances.
What happens during this connection?
- Charging takes place in one phase. Despite using a three-phase socket, American Teslas only support single-phase current. This limits the charging power to 7.4 kW.
- Adapters. For connection, an adapter is required to convert the three-phase current to a format compatible with a single-phase charger.
Conclusion:
- It is possible to use a three-phase socket for the American Tesla, but the charging speed will remain the same as in the case of a single-phase blue socket.
- For maximum efficiency, owners of American models are advised to install blue sockets.
