Best CHAdeMO ↔ CCS EV Charging Adapters Electric vehicle (EV) owners with older Japanese cars like the Nissan Leaf, Kia Soul EV, Mitsubishi i-MiEV, or Outlander PHEV (all of which use the CHAdeMO DC charger plug) are increasingly stranded as U.S. fast-charging networks shift to CCS (Combined Charging System) or Tesla’s NACS. (Nissan has sold over 210,000 Leafs in North America, all with CHAdeMO ports, yet many DCFC stations now only offer CCS1 plugs.) To bridge this gap, aftermarket CHAdeMO-to-CCS adapters (and vice versa) have appeared. These heavy-duty adapters let a CHAdeMO-port EV charge from a CCS1 DC fast charger or allow a CCS1 EV to use a CHAdeMO charger. They’re essentially small computers with cables. In this guide we review the top CHAdeMO ↔ CCS adapters on the U.S. market, link to Amazon listings, and cover specs, pros/cons, compatibility, charging speed, build quality, and real‐world usage. How CHAdeMO↔CCS Adapters Work EV charging adapters like these are essentially DC protocol converters. The CCS and CHAdeMO standards use different electrical and data interfaces: CCS (and Tesla’s NACS) use power-line communication (PLC) for the handshake, whereas CHAdeMO uses a separate CAN-bus signal. The adapter houses a battery-powered controller that translates between the protocols. In practice, you plug the adapter into the charger (e.g. CCS1 output) and then plug its CHAdeMO end into your car (or vice versa). The adapter lights up and runs self-tests, then initiates charging. Because the translator circuitry adds complexity, these adapters are much larger and heavier than simple AC or Tesla adapters. For instance, one CHAdeMO→CCS adapter on Alibaba is described as “big, bulky, and expensive”. Safety is critical: most designs include fuses and temperature cutoffs (e.g. dual thermal kill-switches) to shut off if something overheats. Key Specs: Adapters are usually rated up to 250 A and 1000 V, i.e. 250 kW max. (This exceeds what most CHAdeMO cars can use – e.g. the Leaf’s onboard charger maxes at 62.5 kW.) The actual charging speed will be limited by your car’s capability and the station’s output. All adapters list an IP rating (typically IP54 or IP55 for dust/water resistance. Because firmware can be updated, some vendors promise fixes for new charger models. In short, these adapters work like a small DC fast-charger “translator box” between your car and the charging station. Why You Might Need a CHAdeMO to CCS Adapter With more EVs hitting the road, charging connector types can be a headache—especially when you’re switching between CCS and CHAdeMO plugs. Whether you drive a Nissan Leaf, Kia Soul EV, or older Tesla, a reliable adapter lets you charge across multiple networks without getting stranded. Things to Know Before Buying a CCS or CHAdeMO Adapter – Always check vehicle compatibility (some EVs don’t support adapter use).– Make sure the adapter supports DC fast charging (Level 3).– Look for UL or CE certification for safety.– Check if the adapter has heat-resistance and IP-rated waterproofing.– Compare charge speed (kW), supported voltage, and connector type (male/female). Top Picks: CHAdeMO ↔ CCS Adapters CCS1 To CHAdeMO EV Charger Adapter | 250A CCS Essentially the same spec 250A/1000V adapter sold under another listing. Like the TryBox unit, it’s rated for up to 250 kW and uses durable titanium-copper conductors. Pros/Cons: Similar to above (good capacity, but high cost and heavy). Check Price CCS1 To CHAdeMO Adapter | 250 A | 1000 V (up to 250 kW) for CHAdeMO EVs Designed for Japanese EVs (Leaf, Soul EV, etc.), it promises fast charging performance. Pros: High current capacity, rugged shell, built-in temperature safety. Cons: Very expensive (~$1.7K on Amazon), no official UL/SAE certification, bulky size. Check Price Lectron J1772 to Tesla Adapter | 80 Amp | 250V The Lectron J1772 to Tesla Adapter (80 Amp, 250V) is designed to help Tesla owners access a broader range of public charging stations across the U.S. It’s especially useful for those who regularly drive long distances. Check Price What to Look For When shopping for a CHAdeMO to CCS adapter (or CCS to CHAdeMO): Current & Voltage Rating: Aim for at least 100–150 A continuous, but higher is better if the adapter is sturdy. Most top models support up to 250 A/1000 V (250 kW). This ensures you won’t bottleneck faster chargers, even though many older EVs won’t use the full amount. Compatibility: Ensure the adapter matches your CHAdeMO and CCS version. In the U.S., CHAdeMO is standard (single port) and CCS1 (Combo 1) is used for DCFC. (CCS2 and CHAdeMO 2 are mostly European.) Check the product title: e.g. “CCS1 to CHAdeMO” for a CHAdeMO EV to use CCS1 chargers. Also verify it supports your car – typically all CHAdeMO EVs (Leaf, Soul, Mitsubishi) are supported. Build Quality: Look for robust housings and connectors. Many adapters use UL94-V0 or similar flame-retardant plastics. Check for integrated protection features (over-temp, short-circuit). Models like A2Z’s are UL/CE tested. A solid metal or thick plastic handle, indicator LEDs, and sturdy plugs are a must. Ease of Use: The best adapters are plug-and-play: you usually just plug the adapter into the charger cable, then into your car, and press “start.” Some adapters (like A2Z’s) include simple toggles or buttons for firmware modes, but most require no extra steps. Having a carrying case, USB update cable and a 12 V charge cord (to power the adapter’s battery) are nice bonuses (as one user praised on the Accraine model). Safety & Warranty: Be wary: no carmaker or charger network officially endorses these adapters. The CHAdeMO association warns of potential risks (electric shock, burns) and disclaims liability. Look for any available warranty (A2Z offers 1 year; some sellers offer return guarantees). Inspect user reviews: one Leaf owner found the Accraine adapter reliable across networks and called it “good value”. Others note you must charge the adapter itself (its internal battery) via USB or 12 V before use, so budget that into your prep time. Price: Expect to spend $800–1,800 on a CHAdeMO–CCS adapter. For example, the A2Z/Accraine style units run around $999–1,200, while random Amazon imports often list at $1,499–1,786. Price often reflects testing and support; A2Z’s $999 adapter was explicitly tested for safety, whereas many
