With the growing adoption of electric vehicles (EVs) in North America and around the world, more drivers are enjoying the convenience of green mobility. However, for owners of older or imported models, a practical challenge remains: vehicles like the Nissan Leaf and Mitsubishi Outlander PHEV still use the CHAdeMO fast-charging interface, while newly built public fast-charging stations in North America predominantly support CCS1 or NACS standards. As CHAdeMO charging stations gradually decline in number, many owners worry about the charging options for their older EVs.

According to the latest data from the U.S. Department of Energy’s Alternative Fuels Data Center (AFDC) and EV Charging Stations, as of January 2026, the total number of public DC fast-charging connectors in the U.S. is approximately 67,916. NACS (Tesla / SAE J3400) accounts for around 48.2%, CCS1 for about 31,350 (approximately 40%), and CHAdeMO connectors number only about 8,900 (less than 12%). CHAdeMO saw minimal growth in 2025, with only about 181 new connectors added—less than 1% increase—while CCS1 connectors increased by approximately 9,850 in the same year, a 37% annual growth rate. This clearly shows that CHAdeMO deployment is stagnating or declining, while CCS1 and NACS stations are expanding rapidly. As a result, drivers may encounter difficulties finding compatible fast chargers during daily commutes, long trips, or emergency charging situations.

The good news is that the CCS1 to CHAdeMO adapter provides a practical solution. It enables CHAdeMO vehicles to use CCS1 fast-charging stations, allowing owners to charge their cars without replacing the vehicle or relying on the limited CHAdeMO network. Whether for daily commuting, weekend trips, or emergency power needs, the adapter ensures a smoother, more reliable EV charging experience. It allows older vehicles to continue operating confidently while taking full advantage of modern charging networks.

This guide will provide a detailed overview of how CCS1 to CHAdeMO adapters work, key selection criteria, and a comparison of mainstream brands. Real-world usage examples will help you choose the product best suited to your vehicle and driving habits, making every charge more efficient and reliable.

1. Overview of CCS1 to CHAdeMO Adapters

A CCS1 to CHAdeMO adapter is more than a physical connector; it includes a protocol translation module. Its main functions include:

Electrical conversion: Safely converts the DC power output from a CCS1 station to a current suitable for CHAdeMO.

Protocol handshake: The internal controller simulates the CHAdeMO communication protocol to enable compatibility between the charger and the vehicle.

Safety protection: Overcurrent and overvoltage protection, along with temperature monitoring, ensures safe charging.

Unlike CCS2 adapters, the CCS1 version is primarily designed for the North American and Canadian markets and is optimized for the unique CCS1 charging handshake protocol.

2. Key Selection Criteria

Recommended selection process:

Confirm the vehicle’s supported CHAdeMO maximum current and voltage
Different models (e.g., Leaf, Outlander) have different maximum accepted currents. Compare these with the adapter’s rated specifications.

Check the charging station’s output power
Select an adapter that matches the output power of the CCS1 stations you commonly use.

Firmware upgrades and after-sales service
Prioritize brands that support firmware updates and have active maintenance to avoid future compatibility issues.

Review real user feedback and case studies
Pay special attention to experiences from users with the same vehicle model.
