The Tesla Wall Connector comes with tons of features in the smartphone app to help you monitor and control your energy use. However, this charger can not be plugged in, so you’ll need to contact a professional electrician to install it for you. If you need to plug your Tesla into a 240-volt outlet, there are Mobile Connectors.

If you ever invite other EV owners to your home, the Tesla universal connector will allow you to charge any NACS and/or J1772 electric car.
What To Look For In an EV Charger
If you’re looking to install a level 2 EV charger to install in your home, the first thing you should do is make sure it has the same connector as your electric car. You should also get a charger that can deliver at least 7.7kW (32 amps) of power or more, depending on your on-board charger’s power rating.

Types of EV Connectors
In the US, there are really only two types of charging ports built into electric cars. All Tesla cars now use an NACS (North American Charging Standard) connector, while all other electric cars use an SAE J1772 connector. You should only get an EV charger that has the same type of connector as your electric car.
While you can use an adapter to charge your electric car, it’s not advisable to do so on a regular basis.
How Much Power Does Your EV Charger Need?
Before you install an EV charger in your home, it’s important to check your on-board charger. All electric cars have an on-board charger to convert alternating current (AC) into direct current (DC). The power rating of your on-board charger will determine the maximum charging speed you’ll get from level 2 chargers.
For example, if your EV’s on-board charger is rated at 7.7kW, and you connect to an 11.5kW charger, it will only charge at 7.7kW. So, basically, you want to look for a charger that can supply as much power as your on-board charger can receive – or more.
All level 2 EV chargers carry 240 volts, which is why you might see the power output of a charger listed in amps instead of kilowatts (kW). To find the actual power output of an EV charger, all you need to do is multiply the volts (240) by the amps. This will give you the total watts, and you can divide that number by 1,000 to calculate the kilowatts.
For example, if you see a 32-amp charger, that means it can deliver 7,680 watts (or 7.7kW). However, some EV chargers will list the maximum amps a charger can handle rather than the actual amps that can be used to charge an EV.

Hardwired vs Plug-in EV Chargers
When choosing an EV charger, one of the most important things to consider is whether you want to hardwire it directly to your circuit breaker or if you just want to plug it into a 240-volt wall outlet. Hardwired chargers are safer, easier to use, and deliver more power, while plug-in chargers are easier to upgrade.
The US National Electric Code (NEC) says all EV chargers use a “continuous load,” and by law, they can only deliver 80% of the maximum charge at any time. Since NEMA outlets can only deliver up to 50 amps, the most you’ll get from a plug-in charger is 40 amps (or 9.6kW). On the other hand, hardwired chargers are able to handle 60 amps or more.
Plug-in chargers can also suffer from “nuisance tripping,” which can cause your power to go out regularly. The NEC now requires all 240-volt outlets to have GFCI protection. Since most EV chargers already have GFCI protection built-in, the two GFCI breakers can trip each other and cause your power to trip. So, it’s best to choose a hardwired EV charger whenever possible.
Which NEMA Outlet Should You Use?
When installing a plug-in EV charger in your home, not all NEMA outlets will give you the same amount of power. You’ll get the fastest charging speeds from NEMA 6-50 and NEMA 14-50 outlets, which can both deliver up to 9.6kW. The next-best choices are NEMA 14-30 and NEMA 10-30 outlets, which can deliver 5.8kW.
