Best CCS Adapters for Teslas – How to charge Teslas on CCS in North America

Not all Tesla cars can accept energy from CCS chargers. Earlier cars may not have the necessary hardware to communicate over the CCS protocol. You can confirm that your Tesla is compatible by going to the Software menu in your car and tapping on Additional Vehicle Information.

Here you want to see that CCS adapter support is “Enabled”, instead of “Not Installed”.

Teslas manufactured after October 2020 for the North American market should be compatible. But earlier models are potentially upgradable by Tesla Service. A new ECU upgrade is required the car reports CCS as unsupported. CCS compatibility can be retrofitted by Tesla’s mobile service.

The CCS adapter from LENZ is one of the best-value products in this category. Not only does it exceed required safety specifications, but it can deliver the full 250 kW supported by Tesla vehicles (in optimal conditions). This adapter product felt lighter in weight than competing alternatives and also includes a carrying case to keep the contact points clean while stored in your Tesla.

LENZ is a newer, California-based brand of charging products for EV drivers. We were impressed with their product designs and competitive pricing.

Specs

• CCS1 to Tesla (NACS) adapter
• Up to 250 kW charging speed
• Operating temperature range: -22 °F to 122 °F
• SGS listed to comply with UL 2231
• Includes carrying case
• 2 Year warranty

The newest version of the CCS to NACS adapter from Raylix has a longer “nozzle” and narrower dimensions at the bottom of the casing, making it compatible with the Cybertruck. Most other adapters get caught on the plastic trim of the wheel fenders, preventing the adapters from making a connection. But the Raylix adapter is one of few good products that is compatible with Cybertruck as well the rest of Tesla’s lineup.

We have not personally tested this product yet, but it has good third-party ratings and is specced to handle up to 400 amps and 30,000 usage cycles.

Specs

• Power: 250 kW
• Max amps: 400
• Rated for 30,000 mating cycles
• One year warranty

Lectron is a reputable brand in EV charging, and this CCS adapter is another well-built product. A 300 amp limit on this adapter means a theoretical max speed of 150 kW. However, in practice, we have seen a 131 kW peak, because Teslas’ voltage typically hovers closer to 400 volts than 500.

We tested the Lectron CCS adapter at six different DC charging stations, and it has been very reliable. The overall construction feels solid, but the thin plastic stick above the Tesla plug is the weakest point. This thin plastic stopper prevents the adapter from damaging the Tesla charging port. This is the product we decided to keep for daily usage.

Specs

• CCS to Tesla adapter
• 500V and 300A maximum
• 150kW
• Operating temperature range: -22 °F to 122 °F
• IP44 waterproof rating

The CCS adapter from tesplus appears visually and functionally the same as the one from Lectron. In fact, we would recommend purchasing whichever product is less expensive on Amazon at your time of purchase. The tesplus adapter has more user reviews, but that is likely because it was listed for longer.

The product description says up to 250 kW, but you are more likely to get ~130 kW in typical usage. CCS supports 250 kW and beyond, but because of the 300 amp limit of this adapter and Tesla being on 400-volt architecture, the user is unlikely to get more than 150 kW in optimal conditions. This is plenty fast! The tesplus CCS adapter has great reviews from other users too.

Specs

• Operating temperature range: -22°F to 122°F
• IP54 water resistance rating, splash and rainproof
• Max power: 250 kW (stated)
• Max amps: 300

For an EV battery to charge at the fastest possible speeds, it needs to reach a certain temperature range. (Typically 104° F – 120° F)

When a Tesla car is navigating to a Supercharger, it begins to precondition the battery for fast charging by warming it up. However, there is no option to manually begin to precondition the battery for non-Superchargers. So to get fast charging speeds from CCS EV chargers, the trick is to set the Tesla navigation to a nearby Supercharger, but instead drive to the CCS charger.

Doing this 10-15 minutes before your CCS charging session will warm the battery enough to get 100+ kW or more. This is especially important in colder weather in freezing temperatures because a cold battery would not be able to accept much more than ~40 kW for the first few minutes of charging.

And just as with Superchargers, you will need to arrive with a relatively low state of charge percentage to get the maximum speed. Aim to arrive at a DC fast charger with 10-20% remaining and a warm battery pack to get the most efficient and fastest charging session.
