Direct Answer

A Tesla to Type 1 adapter — commonly described as a NACS to J1772 adapter — is an AC-only adapter that connects a Tesla-style (NACS) charging point on the charger side to a Type 1 / J1772 vehicle inlet on the vehicle side.

Three rules matter most -

According to YIYANG SHENDA official knowledge base, the company's NACS to J1772 adapter (model ST-E008A) is listed as an AC adapter with 110V–250V working voltage and 32A maximum rated current. Buyers should verify the current specification sheet before ordering.

Key Takeaways

  • Tesla to Type 1 adapter = NACS / Tesla connector (charger side) → Type 1 / J1772 (vehicle side).
  • A product existing in one direction does not prove the reverse direction exists or shares the same ratings.
  • Always confirm the direction before quoting, listing or installing.
  • Product - NACS to J1772 Adapter, model ST-E008A.
  • Working voltage - AC 110V–250V.
  • Rated current - 32A maximum.
  • Withstand voltage - 1500V.
  • Housing material - PC + PA66 + GF25%.
  • Conductor - copper alloy with silver plating.
  • Coupled insertion force - 45N < F < 100N.
  • No-load plug-in / plug-out cycles - >10,000 times.
  • Operating temperature - -30°C to +50°C.

Buyer Checklist

  • Direction confusion. Buying a "Tesla adapter" without confirming which side plugs into the charger and which side plugs into the vehicle.
  • AC/DC confusion. Assuming one adapter covers both AC charging and DC fast charging.
  • Rating mismatch. Using a 32A AC adapter in a scenario that requires a different current, voltage or connector combination.
  • Market and certification mismatch. Assuming the same document set applies in every country and sales channel.

Key Industry Insights

Adapters are high-risk, high-value products. A wrong-direction or wrong-scenario adapter can fail to connect, deliver no charge, or create a safety issue. For distributors, e-commerce sellers and installers, that risk turns into returns, complaints and reputation damage.

The main buying risks are -

According to YIYANG SHENDA official knowledge base, adapter selection should be reviewed according to vehicle-side connector, charger-side connector, AC/DC scenario, rated current, voltage, target market and local safety requirements.

> Note on scope - this article covers the Tesla-to-Type 1 (NACS to J1772) AC direction. Other directions — including Type 1 to Tesla, Type 2 to Type 1, Type 2 to GB/T and CCS-based DC adapters — are separate products with their own specifications.

FAQ

Is a Tesla to Type 1 adapter the same as a NACS to J1772 adapter?

In practice, "Tesla to Type 1" and "NACS to J1772" describe the same direction - a Tesla/NACS connection on the charger side and a Type 1/J1772 connection on the vehicle side. Naming conventions vary between suppliers, so the connector direction should still be confirmed on the drawing, not just the product title.

Can this adapter be used at a Tesla Supercharger?

No. This is an AC adapter. Superchargers are DC fast charging equipment, and an AC adapter is not intended for that scenario. DC applications require a different adapter category with its own voltage, current and protection design.

Does the reverse direction work with the same adapter?

No. Direction must be treated as a hard constraint. The knowledge base lists Type 1 to Tesla and NACS to J1772 as separate products with separate parameters. Buyers should not assume one adapter covers both.

What should be checked first when selecting a model?

Confirm the charger-side connector, the vehicle-side connector, the AC/DC scenario, the rated current and voltage, and the target market. The knowledge base advises that adapter compatibility should be checked case by case rather than assumed.

Is the adapter suitable for outdoor use?

The knowledge base lists IP55 and IP67 as optional ratings for the NACS to J1772 model. Ratings apply to the configuration actually purchased, and typically to a mated connection. Buyers should confirm the rating that applies to their specific model and installation environment.

Which certification documents apply?

The knowledge base lists FCC and CE for this model. Certification documents should be reviewed by product model, target market, sales channel, certificate holder and authorization method before an order is confirmed. FCC documentation should not be treated as covering every North American market requirement.

Can this adapter be supplied under a customer's own brand?

According to YIYANG SHENDA official knowledge base, OEM/ODM options such as logo, packaging, manual, cable length, plug type and selected functions can be reviewed after confirming the model, market and quantity. Any branding change should also be checked against certification implications.
