You’ve decided that Tesla is the electric vehicle for you, but which home charger should you buy? While Tesla sells its own charging equipment, there are other lots of other options to consider. Here’s a breakdown of how EV charging works and how quickly the different chargers can charge your Tesla so you can decide which charger is the right choice for your needs.
(Almost) Every Tesla has a Level 1 charger
Your Tesla comes with a Level 1 charger that you can plug into a standard 120-volt outlet. It includes a handy carrying bag, 20-foot cable, and an adapter for use at public charging stations that might not otherwise accommodate your Tesla’s unique charging port. A Level 1 charger is the slowest way to charge an EV. On average, it delivers just 4 miles of range per hour, so this isn’t the best solution.
The upside to using this type of charger is that it requires no special equipment, just a typical household outlet. The only added expense you’ll have to worry about is the cost of having an electrician install a plug near where you park if there’s isn’t an accessible plug already.
Update: As of April 17, 2022 Tesla vehicles no longer come with a corded mobile connector and it’s sold separately for $200.
Upgrading to Level 2
A Level 2 charger significantly increases the speed at which you can fully charge your Tesla. These chargers are typically 240 volts and deliver around 25 miles of range per hour. Rather than buying a Level 2 charger, you can purchase Level 2 adapters for your Tesla Level 1 charger directly from Tesla. These plugs come in a variety of styles that work with different 240-volt outlets, so you can take advantage of the faster charging whenever and wherever it’s available.
While this option works, at home you might find it more convenient to leave the Level 1 charger and any adapters tucked away in your vehicle to use only when needed out on the road. Installing a Level 2 charger at home is an easier solution for daily charging rather than bundling up the Level 1 charger and its adapters and tossing all that equipment in your trunk every morning.
Level 2 chargers are available as either plug-in units or hardwired units. A plug-in unit simply requires the appropriate outlet, which is generally a NEMA 14-50 or 6-50. These are the same kinds of outlet that are used to power a clothes dryer. If you already have one installed near where you park, then you’re all set. Otherwise, you should call a licensed electrician to professionally install this outlet to ensure it operates properly.
If you choose to go with a hardwired Level 2 charger instead, then you absolutely need an electrician to do the installation work. This does cost more than having a simple outlet installed, but a hardwired Level 2 charger has its benefits. They’re often a better solution if you have extreme weather conditions like severe snow or rain. They’re also a better choice if you’re concerned about theft since someone can easily unplug a plug-in charger and walk away with it while a hardwired unit poses more of a challenge.

3. Siemens US2 VersiCharge Universal

4. Tesla Wall Connector

Depending on exactly which Tesla you own and how its configured, you can get up to 44 miles of range per hour.
