Head to head
Emporia vs Tesla Wall Connector
Same 48 amps, same 24-foot cable. The real question is the plug on the end, and whether a car that is not a Tesla will ever use this charger.

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.
This is the decision most Tesla owners actually face, and it is usually framed as brand loyalty. It is really a connector question, and the answer depends on the household rather than the car.

The connector question
A J1772 charger like the Emporia charges any car. A Tesla uses the J1772 adapter that ships with it; everything else plugs straight in. A NACS unit like the Wall Connector charges Teslas natively and everything else only through an adapter on every single charge.
So the question to ask is not "do I drive a Tesla" but "will anything else ever use this charger" -- a second car, a future car, a visiting relative. If the honest answer is "never", the Wall Connector's native fit and longer warranty win. If it is "maybe", the J1772 unit keeps working when the household changes. Plug types explained.
The warranty difference is real
Four years against three. We cannot tell you how either unit holds up over a decade -- we have not run them, and nobody else has run them that long either. The warranty is the part you can hold a manufacturer to, and on a hardwired device where a replacement means an electrician, the extra year is worth something. Warranties compared.
Both units in full
Full specifications and the case against each.
1. A first charger, hardwired
Emporia Level 2 EV Charger (Classic)
Emporia · J1772 · 48 A / 11.5 kW · 24 ft cable
The safe default for a first home charger: 48 amps hardwired, a genuinely long cable, a NEMA 4 outdoor-rated case, and no subscription attached to the app.
What is good
- 48 A hardwired is the fastest tier most homes can realistically support
- 24 ft of cable reaches across a two-car garage without a fight
- NEMA Type 4 enclosure is rated for outdoor mounting
- Energy monitoring in the app with no subscription
What is not
- Drops to 40 A if you use the NEMA 14-50 plug rather than hardwiring
- The app is the only way to change the amperage setting
| Maximum output | 48 A / 11.5 kW at 240 V (hardwired) |
|---|---|
| Plug-in output | 40 A with the NEMA 14-50 plug |
| Connector | SAE J1772 |
| Cable | 24 ft |
| Enclosure | NEMA Type 4, indoor or outdoor |
| Certification | UL listed, Energy Star |
| Warranty | 3 years |
Skip this if: Skip it if you want a unit with no app or network connection at all. The Grizzl-E Classic is the simpler machine.

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
| Maximum output | 48 A / 11.5 kW at 240 V |
|---|---|
| Connector | NACS (Tesla) |
| Cable | 24 ft |
| Installation | Hardwired |
| Power sharing | Up to six units can be linked |
| Warranty | 4 years |
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, for the native fit, power sharing and the four-year warranty. Emporia for anyone who might ever charge a non-Tesla, or who wants a plug-in unit they can take with them. Charging a Tesla at home covers the routes in more depth.
