When driving a Tesla Model S, there is a question that comes up more often than you might think.

"Can I charge my Tesla using a regular 110V outlet at home?"

The answer is YES, it can be charged.

However... the speed is incredibly slow haha

Especially the Tesla Model S is a large battery model, so it takes a very long time.

To charge from 0% to 100%, it can take at least 3 to 4 days.

Most household power in the United States is 110 volts. That's the outlet we use at home.

Electric vehicles can also be charged with the included charging adapter. However, this is classified as a level 1 charger.

The Tesla S has different battery capacities depending on the trim, but it is about 75 to 100 kWh, which is quite large.

In simple terms, it's similar to charging about 1,000 iPads at once in terms of power consumption.

110-volt level 1 charging provides about 3 to 5 miles of driving range per hour.

This means that even if you charge for 12 hours overnight, you'll only get about 40 to 60 miles.

In fact, if your round trip to work is about 30 miles, charging overnight may be sufficient.

This is similar to operating a plug-in hybrid vehicle.

But what if you suddenly need to go on a trip or have to go far in a hurry?

The immense stress of finding a nearby charging station while using an app follows.

So the alternative is to install a level 2 charger at home.

Level 2 charging uses a voltage of 240 volts, which is 2 volts higher, allowing for about 20 to 30 miles of charging per hour, so you can charge over 200 miles overnight.

However, installation costs about $1,000 to $2,500, depending on the electrical wiring situation in your home. Laws vary by region, so sometimes a professional technician is required, while in other areas, DIY is possible.

Of course, you can also utilize Tesla superchargers nearby. However, superchargers are not ideal for frequently charging the battery to 100%, and since they are fast chargers, the cost is quite high.

As mentioned, you can charge a Tesla S with just a 110-volt outlet at home. However, the speed is very slow. Even charging overnight for 12 hours may not yield 50 miles. Therefore, if you are considering long-distance driving, installing a level 2 charger is almost essential.

In fact, for short-distance drivers commuting to work or school, "charging leisurely overnight" is possible, but the issue is that it requires a complicated charging habit.

Electric vehicles free you from the stress of going to gas stations, but they require a "charging plan" instead.

Spending the evening charging leisurely at home with 110 volts isn't bad either.

However, if long-distance driving is necessary, ... you need to charge well in advance.
