EV Adapter FAQs

General Questions

What is an EV adapter, and why do I need one?

An EV adapter enables your EV to charge at different types of charging stations by connecting your vehicle’s charging port to the station's plug type. This is essential for ensuring compatibility when using public charging stations or different charging setups at home.

How do I choose the right adapter for my EV?

To select the correct adapter, identify your EV’s charging port type and the charging station you plan to use:

  • Tesla to CCS1 Adapter: For non-Tesla EVs charging at Tesla V3 or V4 Superchargers.
  • CCS1 to Tesla Adapter: For Tesla vehicles charging at CCS1 fast charging stations.
  • Tesla to J1772 Adapter: For J1772 EVs charging at Tesla Level 2 chargers (e.g., home chargers or destination chargers).
  • J1772 to Tesla Adapter: For Tesla vehicles charging at J1772 AC Level 1 or Level 2 charging stations.
My car is a Tesla, which adapter should I get?

If you want to charge your Tesla at a CCS1 charging station(DC Charging Station), choose the CCS1 to Teslas adapter. If you’re charging at a J1772 (AC)station, choose the J1772 to Tesla adapter.

My car is not a Tesla, which adapter should I get?

If you want to charge your car at a Tesla Supercharge, choose the Tesla to CCS1 adapter. If you’re charging at a Tesla wall charger, choose the Tesla to J1772 adapter.

Do these adapters support fast charging?

Check the adapter specifications and charging station type to confirm compatibility.

Supports Fast Charging: Tesla to CCS1 and CCS1 to Tesla adapters (DC fast charging).

AC Charging Only: Tesla to J1772 and J1772 to Tesla adapters (Level 1 and Level 2 charging).

What should I consider before buying an adapter?

Before purchasing, check the following:

  • Your EV’s charging port type (Tesla, CCS1, or J1772).
  • The charging station type you frequently use.
  • The charging speed you need (Level 1, Level 2, or DC fast charging).
  • Compatibility requirements, such as enabling CCS1 for Tesla vehicles.
Can these adapters be used for Level 1, Level 2, and DC fast charging?
  • Level 1 (120V AC): Only J1772 to Tesla and Tesla to J1772 adapters support Level 1 charging.
  • Level 2 (240V AC): Both J1772 to Tesla and Tesla to J1772 adapters work for Level 2 charging.
  • DC fast charging: Only Tesla to CCS1 and CCS1 to Tesla adapters are compatible with DC fast charging stations.

Before charging, confirm the type of station and ensure it matches your adapter's specifications.

Are these adapters safe to use?

Yes, all our adapters are rigorously tested to meet industry safety standards. They are built with durable materials to ensure safe and reliable charging for your EV.
