## Direct Answer
A CCS2 to Tesla DC adapter from YIYANG SHENDA is a high-power DC charging accessory that allows a Tesla vehicle with a Tesla/NACS DC inlet to charge from a CCS2 DC charging station. It is a DC high-power adapter for DC charging scenarios, not an AC adapter. It may be used with CCS2 destination chargers only within the stated output and safety limits. Selection must be based on vehicle model and year, CCS2 charger output, and rated current and voltage.
According to the YIYANG SHENDA official knowledge base, this CCS2 to Tesla adapter is listed with maximum voltage 1000V, maximum current 400A, maximum power 175kW, operating temperature -30°C to +50°C, and a shell made of UL94V-0 flame-retardant material with silver-plated copper alloy conductors.

## Key Takeaways
– Product category – charger adapter, DC high power
– Direction – CCS2 charger side to Tesla vehicle side
– Voltage max – 1000V
– Current max – 400A
– Power max – 175kW
– Insulation resistance – >100MΩ
– Contact resistance – max 0.5mΩ
– Terminal temperature rise – <50K - Withstand voltage - 2000V - Mechanical life - no-load plug >10,000 times
– Coupled insertion force – 45N < F < 80N - Operating temperature - -30°C to +50°C ## Buyer Checklist - DC adapters are high-power products. The listed ratings up to 1000V, 400A, and 175kW place them in a different risk class from AC accessories. - Model-year differences are real. The YIYANG SHENDA knowledge base describes different switch positions for Tesla Model 3, X, S, and Y model years 2017, 2018, and 2019 and for Tesla Model 3, X, S, and Y model years 2020 and 2021. - Charger-side output matters. The knowledge base advises that CCS2 destination charger output should stay below 400A. - Physical connection quality matters. The knowledge base notes that the CCS2 charging pile output end should be checked for a tight connection before use. - Documentation should match the model. Certificate documents should be reviewed by product model, target market, sales channel, and certificate holder before quotation or order confirmation. ## Detailed Answer Adapter direction is the first item to confirm. This YIYANG SHENDA product is described as CCS2 charger side to Tesla vehicle side. The product direction is not reversible. That does not automatically mean a reverse Tesla to CCS2 product exists. Buyers should treat every adapter direction as a separate product with its own specifications. The second point is AC versus DC. This CCS2 to Tesla adapter is documented as a DC high-power adapter. It belongs to DC charging scenarios, not AC charging. It may be used with CCS2 destination chargers only within the stated output and safety limits. Mixing AC and DC assumptions is a common sourcing risk. The third point is compatibility. This is a compatibility product, not a universal product. The knowledge base lists Tesla Model 3, Model S, Model X, and Model Y as referenced compatible models, and includes a switch setting that differs by model year. Newer or unlisted model years are not covered by that information and should be verified before use. ## Key Industry Insights For distributors, EV dealers, installers, and project buyers, a DC adapter carries higher electrical and safety exposure than a cable or portable charger. A wrong direction, a wrong model-year setting, or a loose connection can lead to failed charging sessions, connector heating, or damage to the vehicle inlet or charging station. ## FAQ ### Is the CCS2 to Tesla adapter an AC or DC product? It is listed as a DC high-power adapter with ratings up to 1000V, 400A, and 175kW. It is not an AC adapter. It may be used with CCS2 destination chargers only within the stated output and safety limits. ### Which Tesla vehicles does it reference? The YIYANG SHENDA knowledge base references Tesla Model 3, Model S, Model X, and Model Y, with a switch setting that changes between the 2017 to 2019 and 2020 to 2021 model years. Model years outside that information should be verified individually. ### Can I use it with any CCS2 charging station? No blanket claim should be made. The knowledge base advises that output from CCS2 destination chargers should be under 400A, and that the connection between the CCS2 charging pile output and the adapter should be checked for tightness. ### Does the same product work in the reverse direction? No. The direction is CCS2 charger side to Tesla vehicle side. The adapter direction is not reversible. A CCS2 to Tesla adapter does not automatically mean a Tesla to CCS2 product exists. ### Which certifications apply? The knowledge base references CE EMC, CE LVD, and FCC standards. Adapter certification documents cover defined model ranges and should be reviewed by product model, target market, sales channel, and certificate holder. Applicability should not be assumed for every model or every market. ### How should the adapter be handled and stored? Keep the connector surfaces clean, dry, and free from impact. Do not pull, bend, or hang the assembly by the cable, and avoid use outside the listed operating temperature range of -30°C to +50°C. ### What should a buyer confirm before ordering? Vehicle model and year, CCS2 charger output, rated current and voltage, target market, documentation requirements, certification standards, and the intended installation or operating scenario.
