The CLA Introduces Advanced Charging Technology 

If you’re considering the all-electric 2026 CLA, Mercedes-Benz of Arrowhead in Peoria, AZ, is here to help you understand everything you need to know about charging. As one of the newest models in the Mercedes-Benz EV lineup, the CLA introduces advanced charging technology that ensures faster, more efficient charging both at home and on the road.

Fast Charging with 800-Volt Architecture 

The 2026 CLA offers an 800-volt charging system, allowing drivers to take advantage of the latest ultra-fast charging technology. At 800-volt charging stations, the CLA can add up to 201 miles of range in 10 minutes, perfect for travel. 

Mercedes-Benz has integrated the CLA with its growing network of Mercedes-Benz High-Power Charging hubs, giving drivers access to charging stations across the country. 

400-Volt DC Charging Compatibility 

While the CLA model’s main strength lies in its 800-volt system, compatibility with 400-volt DC chargers will be available in Spring 2026. At that time, new CLA models will come with a factory-equipped converter to connect to 400-volt DC fast chargers. 

• With converter (Spring 2026 and later): Compatible with both 800-volt and 400-volt DC fast chargers. 
• Without converter (launch models): Compatible only with 800-volt DC fast chargers. 

This distinction makes it important to know which charging architecture your CLA is equipped with before planning road trips. 

Dual Charging Ports: J1772 and NACS 

The 2026 CLA will be the first electric Mercedes-Benz model to feature both a J1772 plug and a NACS charging port for DC fast charging. This dual compatibility ensures you’ll be able to plug into a wide range of stations, including the expanding Tesla Supercharger network and other high-power charging networks. 

Additionally, every CLA comes with a CCS-to-NACS DC fast-charging adapter, giving you access to the Mercedes-Benz integrated charging ecosystem. 

Home Charging Options 

For daily convenience, the 2026 CLA can be plugged into the Mercedes-Benz Wallbox at home. This allows for simple, overnight charging, so you can start every morning with a full battery and peace of mind.
