1. What is a CCS Adapter?
A Tesla CCS adapter is a charging accessory made by Tesla or certified third-party brands.
It converts the NACS port (North American Charging Standard) on Tesla vehicles to a CCS port (Combined Charging System).
This allows Tesla owners to charge at third-party CCS fast charging stations.
2.Types of CCS Adapters
There are now two types of CCS adapters: CCS1 and CCS2.
CCS1 is used in North America and Korea.
CCS2 is used in Europe and China.
Different regions have different vehicle and charging standards.
Users should choose the right adapter for their car and location.

3. Charging Port Types in the US
Below is a table of common charging port types in the United States:
Port Type |
Description |
Typical Power Range |
|---|---|---|
NACS |
Used by Tesla Superchargers |
Up to 250kW |
CCS1 |
North American Combined Charging System |
Up to 350kW |
CHAdeMO |
Mainly for Japanese vehicles |
Up to 50kW |
J1772 |
Level 1 & Level 2 AC charging |
Level 2: 7-19kW |
4. Value of the CCS Adapter
Compatibility Expansion:
The adapter breaks brand barriers.
According to data from AFDC (Alternative Fuels Data Center), as of January 1, 2025, there are over 12,400 CCS fast charging locations and nearly 51,000 charging ports in the United States (including about 2% temporarily unavailable ports).
It gives access to a vast CCS charging network in North America.
Emergency Charging:
If a Supercharger is busy or down, CCS stations offer a backup.
Market Data:
Tesla has deployed over 29,000 NACS ports (57% of the total).
Other networks mainly use CCS1.
Electrify America, EVgo, ChargePoint, and EV Connect are the largest CCS networks.
5. CCS1 Adapter Compatibility
Important:
The CCS1 adapter and the CCS charging protocol are different things.
Even if you buy a CCS1 adapter, your Tesla may not support the CCS protocol. according to the Tesla manual.
Some vehicles need a "Charge Port Controller" upgrade.
How to check compatibility:
On your Tesla touchscreen, go to: Controls > Software > Additional Vehicle Information > CCS and Third Party NACS DC Fast Charging Support
You will see one of three statuses:
- Enabled: Your car supports CCS protocol. You can use CCS and third-party NACS chargers.
- Not Enabled: Your car does not support CCS/NACS charging protocol. Check the Tesla app for upgrade options.
- Not Compatible: Your car cannot use CCS protocol. Third-party NACS or CCS charging is not possible. (May require a "Charge Port Controller Module" to support)
Note: Usually Before 2021 Tesla Model 3/Y will not compatible
Example:
There is a video showing a successful CCS1 adapter and Charge Port Controller upgrade on a 2021 Tesla Model 3/Y:
6. Typical Use Cases & Steps
Common Scenarios:
- Long trips: Use CCS stations in areas without Superchargers.
- Cost optimization: Some CCS stations are cheaper than Superchargers, especially at night.
- Sharing: Share CCS stations with friends who drive non-Tesla EVs.
Operating Environment:
Voltage: 500V DC
Enclosure Rating: IP44
Operating Temp: -22°F to +122°F (-30°C to +50°C)
Storage Temp: -40°F to +185°F (-40°C to +85°C)
Caution: Do not use or store the adapter outside these ranges.
7. Summary
The CCS adapter is the "key to charging freedom" for Tesla owners.
During the transition to unified charging standards, the adapter's lightweight design and wide compatibility make it essential for long journeys.
As Tesla opens its network and supports more standards, NACS is becoming the mainstream in North America.
But no matter how standards evolve, breaking barriers and improving compatibility is the real milestone for the electric era.
