Best J1772-to-Tesla Adapters

The single most useful adapter a Tesla owner can buy — it opens every J1772 station to a NACS car. Plus the reverse adapter, if you drive a non-Tesla.

By Stephen V.Last updated How we rank

There are two adapters in the J1772/Tesla family, and which one you need depends entirely on which way you’re going. If you drive a Tesla(or any newer NACS car) and want to use the millions of J1772 Level 2 stations out there — hotels, workplaces, older home chargers — you want a J1772-to-Tesla adapter. If you drive a non-Teslaand want to use a friend’s Tesla Wall Connector or a Tesla Mobile Connector, you want the reverse, Tesla-to-J1772.

Both are cheap, both are AC-only (they will not Supercharge anything), and both are the kind of small part that’s worth keeping in the car permanently. The J1772-to-Tesla adapter in particular is, dollar for dollar, the most useful thing a Tesla owner can buy. For DC Supercharging a non-Tesla, you need a different, pricier part — see our NACS-to-CCS guide.

#1Best for Tesla / NACS owners

Lectron J1772 to Tesla Adapter

The adapter every Tesla owner should keep in the frunk: it lets a Tesla (or any NACS car) charge from the millions of public and home J1772 stations. Cheap, compact, and the single most useful $40 a Tesla owner can spend.

Strengths

  • Opens up every J1772 Level 2 station to a NACS car
  • Rated for full 48A / Level 2 AC charging
  • Small enough to live in the glovebox

Trade-offs

  • AC charging only — this is not a Supercharger or DC-fast adapter
  • Locking behavior varies by station; some public units grip it loosely
ConnectorJ1772 → NACS (Tesla)
Max output48 A
Max power11.5 kW
Cable lengthNot published
InstallPlug-on adapter
Outdoor ratingNot published
Warranty1 year

Spec note. For AC (Level 2) charging only. It does not enable DC fast charging and is unrelated to the NACS-to-CCS DC adapters non-Tesla cars use at Superchargers.

#2Best for J1772 cars

Lectron Tesla to J1772 Adapter

The mirror-image adapter: it lets a non-Tesla EV use a Tesla Wall Connector or Tesla Mobile Connector for AC charging. The right buy if a friend or rental has a Tesla home charger and you drive something else.

Strengths

  • Lets a J1772 car charge from a Tesla Wall/Mobile Connector
  • Handles full Level 2 AC amperage
  • Simple, pocketable, no setup

Trade-offs

  • AC only — will not work at a Supercharger
  • Only useful if you actually encounter Tesla AC connectors
ConnectorNACS (Tesla) → J1772
Max output48 A
Max power11.5 kW
Cable lengthNot published

Outdoor ratingNot published
Warranty1 year

Spec note. Works with Tesla's AC equipment (Wall Connector, Mobile Connector). It is not a DC adapter and does not make a non-Tesla car Supercharge — that needs a NACS-to-CCS adapter and vehicle support.

How to pick the right direction

Read the name literally: a “J1772-to-Tesla” adapter takes a J1772 station’s plug and adapts it toyour Tesla’s port. So a Tesla owner buys the J1772-to-Tesla; a non-Tesla owner who wants to borrow a Tesla charger buys the Tesla-to-J1772. Getting the direction wrong is the only real mistake here, and it’s an easy one to avoid once you know the naming.

What to look for

Check the amperage rating — a good adapter handles full Level 2 current so it never becomes the bottleneck — and look for a snug, positive fit at the station end, since a loose grip on a public unit can interrupt a charge. Beyond that, these are simple parts; a reputable brand at a sensible price is all you need. Keep it in the frunk or glovebox so it’s there when you arrive at a J1772 station.

What it won’t do

Neither of these enables DC fast charging. A J1772-to-Tesla adapter will never let you Supercharge, and it won’t help a non-Tesla car fast-charge either — that’s a job for a NACS-to-CCS DC adapter and the right vehicle support. These are strictly for everyday AC / Level 2 charging.

Frequently asked questions

Do I need a J1772-to-Tesla adapter if my car came with one?

Tesla includes a J1772 adapter with some cars. If you already have one that works and doesn't leave the house, a spare to keep in the car is handy but not essential. If you never got one or it's gone missing, this is the adapter to replace it.

Will this adapter let me Supercharge?

No. J1772-to-Tesla and Tesla-to-J1772 adapters are AC-only, for Level 2 charging. Supercharging a non-Tesla car requires a NACS-to-CCS DC adapter and a compatible vehicle and station — a completely different (and pricier) part.

Which adapter do I buy for a non-Tesla EV?

If you want your J1772 car to charge from a Tesla Wall Connector or Mobile Connector, buy the Tesla-to-J1772 adapter. If you drive a Tesla and want to use J1772 stations, buy the J1772-to-Tesla adapter. Match the adapter to the direction you're charging.

Is it safe to leave the adapter on the cable outdoors?

A quality adapter is weather-resistant, but it's best to remove it and store it in the car when not in use — it keeps the contacts clean and the adapter from walking off at a public station. Don't leave any connector sitting in standing water.
