Autel MaxiCharger vs Tesla Wall Connector

The most output a home circuit will usually carry, against Tesla's own unit. Close on speed; far apart on connector and on how you can install them.

At the top of the home-charging range, 50 A and 48 A are nearly the same thing -- both need a 60 A-plus circuit and a car that can take 11 kW or more. What actually separates these two is the plug on the end and whether you want the option of a receptacle.

The circuit each one needs

The continuous-load rule

Autel at 50 A hardwired: 50 x 1.25 = 62.5, so a 70 A circuit

Tesla at 48 A: 48 x 1.25 = 60 A circuit

Autel at 40 A plug-in: 50 A circuit and a 14-50 or 6-50 receptacle

The installation manual states the circuit, and governs

Who should buy which

  • Every car a Tesla: the Wall Connector, for the connector and the extra warranty year.
  • A J1772 car, or a mixed garage: the Autel, which serves both through the Tesla's adapter.
  • You want to plug in, or might move house: the Autel's 14-50 or 6-50 versions. Hardwired vs plug-in.

1. Long reach outdoors

Autel MaxiCharger AC Home

Autel Energy · J1772 · 50 A / 12 kW · 25 ft cable

The 25 ft cable is the longest in this group, and the NEMA 4 case plus a cold-flexible cord make it the easiest unit to live with on an exposed outside wall.

What is good

  • 25 ft cable, the longest of the wall units here
  • Sold in NEMA 14-50, NEMA 6-50 and hardwired versions
  • NEMA Type 4 enclosure rated for rain, snow, hail and sleet
  • Wi-Fi and Bluetooth, so it still works if the Wi-Fi drops

What is not

  • The 50 A version is hardwired only
  • The app has more features than a first-time owner needs

2. Tesla owners

Tesla Wall Connector (Gen 3)

Tesla · NACS · 48 A / 11.5 kW · 24 ft cable

48 A, a 24 ft cable and a four-year warranty, the longest in this group. The catch is the connector: Gen 3 is NACS, so a J1772 car needs an adapter.

What is good

  • Four-year warranty, longer than the three-year standard here
  • Up to six units can share one circuit for a two-EV household
  • Wi-Fi with over-the-air firmware updates
  • Scheduled departure and charge stats live in the Tesla app

What is not

  • NACS connector, so a J1772 car needs an adapter on every charge
  • Hardwired only

Skip this if: Skip it if you drive a J1772 car and do not want to keep an adapter on the cable. Buy a J1772 unit instead.

The verdict

Tesla Wall Connector for a Tesla-only household. Autel MaxiCharger for J1772 cars, a mixed garage, or anyone who wants a plug-in option. For both connectors on one Tesla-built unit, see the Universal Wall Connector.

FAQ

Questions people actually ask

Is Autel or the Tesla Wall Connector better?
For a Tesla-only household, the Wall Connector: NACS, 48 A and a four-year warranty. For J1772 cars, a mixed household, or a plug-in install, the Autel MaxiCharger, which reaches 50 A hardwired.
Can a Tesla use an Autel MaxiCharger?
Yes, through the J1772 adapter that comes with a Tesla.
Which is faster, Autel or Tesla?
On paper the Autel, at 50 A hardwired against 48 A -- but only if your car's onboard charger accepts about 12 kW and your panel can carry a 70 A circuit.
