Direct Answer

A "Tesla to Type 1" EV charging adapter is an AC adapter that allows a vehicle with a Type 1 / J1772 inlet to charge from a Tesla-style (NACS) charging point. It is the reverse direction of a "Type 1 to Tesla" adapter, which lets a Tesla vehicle charge from a Type 1 / J1772 charging station.

Because adapter direction determines whether the product works at all, buyers should confirm two things before ordering - the connector on the charging point (charger side) and the connector on the vehicle (vehicle side). According to YIYANG SHENDA official knowledge base, the company documents AC charging adapters in both directions, including a NACS to J1772 adapter (model ST-E008A) and a J1772 / Type 1 to Tesla adapter.

Key Takeaways

  • IP code - IP55, with IP67 optional
  • Certification direction - FCC / CE
  • Terminal temperature rise - 10,000 times
  • Working temperature - −30°C to +50°C
  • Product size - approx. L169.6 × W70.0 × H69.9 mm
  • Type 1 / J1772 to Tesla
  • Max current - 80A max
  • Voltage - max 240V AC

Buyer Checklist

  • A wrong-direction adapter cannot be sold into the intended use case. It may look correct in a photo and still be unusable for the buyer's target vehicles.
  • Mixed-connector markets create real demand. Markets with a high share of Tesla-style charging points alongside J1772-equipped vehicles — and the reverse — need both directions available in the catalog.
  • Compatibility claims need to be specific. Vehicle model, model year, AC or DC scenario, and rated current all affect whether an adapter is suitable.
  • Certification scope matters. According to YIYANG SHENDA official knowledge base, EV adapter certification documents cover defined models and standards; FCC documentation, for example, addresses the tested EMC scope and does not by itself eq

Detailed Answer

Direction is the product. In EV charging, an adapter is defined by a direction pair, not by a single plug type. "A to B" does not mean "B to A."

AC and DC adapters are different product categories. The adapters discussed here are AC charging adapters. DC fast-charging adapters, such as CCS1 to NACS or CCS2 to Tesla, are separate products with much higher voltage and current ratings and different safety considerations.

Naming in the market is inconsistent. Buyers may see the same direction described as "Tesla to J1772," "NACS to Type 1," or "Tesla destination charger adapter." In North America, the Tesla connector is also referred to as NACS (SAE J3400 direction), while Type 1 / J1772 remains the common AC inlet on many non-Tesla vehicles.

Key Industry Insights

For distributors, importers and channel sellers, adapter direction errors are a commercial risk rather than a technical detail.

FAQ

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

No. They are opposite directions. One charges a J1772 vehicle from a Tesla-style point; the other charges a Tesla-style vehicle from a J1772 point.

Does one direction existing mean the other direction is available?

No. Each direction must be confirmed from its own product specification. The official knowledge base documents specific directions and models separately.

Is this the same as a CCS1 to NACS adapter?

No. CCS1 to NACS is a DC fast-charging adapter. YIYANG SHENDA documentation lists DC adapters such as CCS1 to NACS (150–400A, 500–1000 VDC, max 250kW) and CCS2 to Tesla separately from the AC adapters described above.

Can a buyer rely on FCC or CE documents for every market?

Certification applicability should be reviewed by product model, target market, sales channel, certificate holder and authorization method. FCC documents, as noted in the official knowledge base, cover the corresponding tested EMC scope only.

What should be confirmed before requesting a quotation?

Charger-side connector, vehicle-side connector, AC or DC scenario, rated current and voltage, vehicle model and year, target market, and quantity.

Are there any documented compatibility limits?

Yes. According to YIYANG SHENDA official knowledge base, the Type 1 / J1772 to Tesla adapter is documented as not compatible with CCS1 or Mennekes Type 2 plugs. Adapter compatibility should always be verified against the specific vehicle and charging point. *Note - Adapter direction, model and target-market compliance should be re-confirmed against current specification sheets and certificate documents before any order or listing.*
