Is a Tesla Home Charger Worth It?

A big part of electric vehicle (EV) charging -- 80% according to the US Department of Energy -- is done at home. After all, the convenience of waking up to a fully charged electric car, ready for a whole day of driving, is one of the top-selling points of EVs. However, the home charging experience greatly varies from EV to EV, and a lot of it has to do with the type of charger used.

There are two types of chargers used for home charging: Level 1 and Level 2. A Level 1 EV home charger typically plugs into a standard outlet (120V) and can give 3-5 miles of range per hour after one circuit of charging. Level 2, on the other hand, can either be plugged into 240V outlets or be hardwired into home electrical systems for up to 40 miles per hour.

What to Know About Tesla Charging at Home

Tesla has one of the most robust charging networks in the industry, thanks to years of research and development. Currently, the Tesla Supercharger network accounts for 63% of public fast chargers in the US, which translates to around 21,000 EV chargers. However, a huge majority of Tesla owners still prefer charging electric car at home, which is understandable since Tesla has included a complimentary Level 1 Mobile Connector with each Tesla vehicle until April 2022.

While incredibly convenient, these chargers offer limited charging speeds of up to 3 miles of range per hour when plugged into a 120V outlet and up to 30 miles an hour with a 240V outlet, depending on the Tesla model. This is primarily the reason why about 60% of EV drivers with Level 1 chargers want to upgrade ev chargers to a more powerful Level 2 charger. For Tesla EV owners, this meant letting go of the free Mobile Connector and having a Wall Connector installed. But is the upgrade really worth it?
