Connectors are not a technical footnote — they are a market-access decision. Ship a CCS2 charger to a NACS-dominated US site and it collects dust. Ship only GB/T to Southeast Asia and you exclude every non-Chinese EV on the road. For a manufacturer like Max Power shipping across 30+ countries, connector strategy is inventory strategy.
Here is the 2026 reality, region by region.
The Four Standards That Still Matter
🇨🇳 GB/T 27930 (China)
Region: Mainland China exclusively — ~33% of global DC charger share by volume
Connector: Separate 9-pin DC round coupler (GB/T 20234.3); AC and DC are different ports
Comms: CAN bus via GB/T 27930
Spec ceiling: 1000V / 250A (legacy 2015); 2023 revision lifts to 1500V / 800A, ~800kW+ with liquid cooling
Next-gen: ChaoJi (joint China–Japan, up to 900kW, IEC PAS 63454) slowly entering high-power corridors
If you sell EVs or chargers inside China, GB/T is non-negotiable. If you export Chinese-brand EVs (BYD, NIO, Geely) to Africa, LATAM, or Central Asia — GB/T output on your charger is a competitive edge, exactly why our Ghana showroom unit shipped dual CCS2 + GB/T [link to Ghana case study].
.
🇪🇺 CCS2 (Combined Charging System Type 2)
Region: Europe, UK, Australia, New Zealand, India, Middle East, most of Africa & LATAM — ~28% global share, the dominant export standard
Connector: Type 2 AC inlet + 2 DC pins, single port
Comms: PLC via ISO 15118 (enables Plug & Charge)
Spec ceiling: 1000V / 500A, 350–400kW deployed, 500kW+ with liquid-cooling; evolving toward MCS (Megawatt Charging System) for trucks
Regulatory: EU AFIR mandates CCS2-compatible public DC by default
This is the first connector any global exporter must support. Our 160kW Bangkok taxi units and 240kW Costa Rica bus units both ship CCS2 as primary [link to case studies].
🇺🇸 NACS / SAE J3400 (North America)
Region: USA, Canada, Mexico, Israel — 48% of North American DC connectors by early 2026, CCS1 down to 40%
History: Tesla proprietary → opened 2022 → ratified as SAE J3400 in 2024; Ford, GM, Rivian, Mercedes, Volvo, Honda all shipping native NACS from 2025
Connector: 5-pin compact, AC+DC in one port, ~half the size of CCS1
Spec ceiling: 1000V / ~500A, 250kW today, 600kW+ on V4 Supercharger hardware
Outlook: CCS1 effectively dead for new builds by 2027; dual NACS+CCS1 outlets now common on US dispensers
🇯🇵 CHAdeMO (Japan)
Region: Japan legacy (Nissan Leaf, older Mitsubishi); ~7% global share, declining
Spec: Up to 400kW on CHAdeMO 2.0; CHAdeMO 2.1 (May 2026) hits 800kW; Japan itself migrating to CCS2 + ChaoJi
Verdict: Do not design new export hardware around CHAdeMO. Support it only as a secondary legacy outlet if serving Japanese fleet retrofits.
2026 Market Share Snapshot
Standard | Global DC share | Trajectory |
|---|---|---|
GB/T | ~33% | China-only, stable |
CCS2 | ~28% | Global export default, growing |
NACS | ~20% | North America consolidator |
CCS1 | ~12% | Phasing out by 2027 |
CHAdeMO | ~7% | Declining to legacy |

Multi-Standard Hardware Is the Practical Answer
Few operators serve one plug type forever. Our approach at Max Power:
Single-unit multi-output: 60kW / 80kW mobile units ship CCS2 + GB/T as standard — covers showroom demos for Chinese EVs and European buses on the same site : [The Mobile DC Charging Playbook: Power Wherever the Work Is]
Fixed DC range (120–360kW): configurable CCS2 / NACS / CHAdeMO / GB/T gun combinations per dispenser
Cable-retractor + dual-gun designs let one power cabinet serve mixed fleets — exactly what the European mountain mine needed for its Chinese-brand excavators and haul trucks [Read the Full European Mine Case Study]
Decision Rule for Buyers
Sell inside China → GB/T mandatory
Export to EU / AU / ME / LATAM / Africa → CCS2 primary
North America → NACS native + CCS1 adapter outlet for legacy
Fleet with Chinese EVs outside China → insist on GB/T + CCS2 dual output
Heavy-duty / mining / ports → plan for MCS migration path alongside CCS2
