Direct Answer

In North America, the two adapter families solve different charging problems, and they are not interchangeable.

The single most important rule - direction matters. "A → B adapter exists" does not mean "B → A adapter exists."

Key Takeaways

  • AC family - J1772 ↔ NACS style adapters such as the Type 1 to Tesla adapter and the ST-E008A NACS to J1772 adapter.
  • DC family - CCS1 to NACS adapters such as ST-E007.
  • ST-E008A (NACS → J1772, AC): AC 110V–250V, 32A MAX, terminal temperature rise 10,000 times, operating temperatu
  • J1772 / Type 1 → Tesla (AC): up to 80A MAX, Max 240V AC, working temperature −22°F to +122°F, intended for Level 1 and Level 2 charging stations and Tesla Model 3 / S / X / Y; not compatible with CCS1 or Mennekes Type 2 plugs.
  • ST-E007 (CCS1 → NACS, DC): 150–400A, 500–1000 VDC, Max 250 kW, operating temperature −30°C to +50°C.

Key Industry Insights

| Connector | Typical role | Charging type |

|---|---|---|

| J1772 / Type 1 | AC charging inlet on many non-Tesla EVs and AC charging stations | AC (Level 1 / Level 2) |

| CCS1 | J1772 body plus DC pins, used by many North American DC fast chargers | DC |

| NACS (Tesla-style, standardized as SAE J3400) | Newer North American vehicle inlet and charger connector | AC and DC |

Because NACS carries both AC and DC, an adapter that matches the shape may still be wrong for the electrical scenario. This is why the YIYANG SHENDA official knowledge base applies an explicit Adapter Direction Gate - every adapter must state Charger Side → Vehicle Side, and must be reviewed by AC or DC scenario, rated current, voltage, vehicle model or year, and target market.

FAQ

Can one adapter handle both AC and DC charging?

No. AC adapters and DC fast-charging adapters are separate product categories with different electrical ratings. Confirm the charging scenario before selecting.

Will a J1772 to Tesla adapter work at a Tesla Supercharger?

No. Superchargers are DC fast-charging equipment. A J1772 to Tesla adapter is intended for Level 1 and Level 2 AC charging stations.

Can a CCS1 to NACS adapter be used with every NACS vehicle and every CCS1 charger?

Compatibility must be confirmed by vehicle model and year, charger-side equipment, rated current and voltage. The knowledge base describes it as designed for CCS1 North American DCFC charging stations and does not support a blanket "fits all" statement.

Does the NACS to J1772 adapter also work in the other direction?

No. The ST-E008A is specified as NACS to J1772. The reverse direction requires its own verified product specification.

Is FCC or CE documentation enough to sell in North America?

Not automatically. Adapter applicability must be confirmed by connector direction, AC/DC scenario, current, voltage and target market. The knowledge base notes that FCC documentation reflects the tested scope and does not by itself represent every North American compliance requirement.

What should a distributor check before listing these adapters?

Vehicle-side connector, charger-side connector, AC or DC, rated current, rated voltage, vehicle model or year, IP rating, operating temperature, packaging and label content, and the certificate documents relevant to the specific model.

Can these adapters be supplied with a customer brand?

Customization options such as branding and packaging are reviewed case by case. The knowledge base advises confirming model, market, quantity and certificate implications before treating any customization as fixed. *Note for buyers - product parameters and certificate applicability should be re-confirmed against the current specification sheet and certificate documents for the exact model before purchase, since connector generations and market requirements can change.*
