Regulation (EU) 2025/2052 is already in force and applies from 14 December 2028. Product teams now have a defined window to turn a connector change into a controlled engineering, compliance and supply-chain plan.
USB-C has largely settled the connector debate. For OEMs and operators, the harder question begins after connection.
Power must be negotiated, delivered and managed reliably across the external power supply, cable and device, during start-up, continuous operation and changing-load conditions. The transition is therefore a product-system issue, not simply a mechanical redesign.
Where the regulation fits
Commission Regulation (EU) 2025/2052 sets ecodesign requirements for external power supplies, wireless chargers, wireless charging pads, battery chargers for portable batteries of general use and USB Type-C cables. It also repeals Regulation (EU) 2019/1782 from 14 December 2028.
The regulation is already in force. Its main requirements apply from 14 December 2028, while a transitional provision supporting early compliance applies from 14 December 2025. The official regulation is available through EUR-Lex.
This is not a blanket requirement for every electronic product to use USB-C. Scope and obligations depend on the product category, design, how equipment is placed on the market and relevant exclusions. Accurate portfolio mapping is therefore the first step.
USB-C is only one part of the power path
USB Type-C defines the physical interface. USB Power Delivery can add power negotiation. The external power supply converts mains electricity into the required output. The cable contributes its power rating, resistance, energy losses and thermal behaviour. The device determines its actual load, start-up demand and response to changing conditions.
A common connector does not guarantee common performance. A robust design may require evidence covering:
· start-up and inrush behaviour;
· guaranteed continuous output and short-term peaks;
· load transitions and voltage stability;
· ripple, noise and cable losses;
· thermal performance within the intended enclosure;
· interoperability across credible device, supply and cable combinations; and
· surge performance where relevant.
The regulation addresses this wider system. Its requirements include energy efficiency at different loads, no-load and standby behaviour, interoperability, technical information and product markings.
Interoperable external power supplies must provide clear power information and, where applicable, display the Common Charger logo. Covered USB Type-C cables must be marked as either 60W or 240W. For dynamic power supplies, guaranteed continuous power is particularly important, rather than relying only on a short-duration maximum.
What teams should do now
1. Map the portfolio
Identify the products and external power supplies that may be affected, including standalone supplies, bundled units, regional variants, replacement parts and installed-base requirements.
Record each product’s interface, voltage, current, maximum or guaranteed power and likely transition route.
2. Establish the real power profile
Nameplate power is only the starting point. Teams should understand start-up current, inrush, continuous demand, peak demand, load changes, thermal conditions and operating headroom.
This confirms whether a USB-C PD design can deliver the required power continuously and reliably.
3. Test the complete CPE power path
Validate the CPE device, its purpose-designed external power supply and the intended USB-C cable as one complete system. Testing should confirm the required USB PD behaviour and reliable performance under real operating conditions, including continuous 24/7 use.
Where replacement cables, third-party cables or regional configurations are part of the intended deployment, test credible, qualified combinations rather than relying on one preferred setup. USB-C compatibility must not be confused with equivalence to a consumer phone charger.
4. Build the evidence and supply-chain plan
Prepare the required technical documentation, product information, markings and service guidance. At the same time, plan component availability, supplier capacity, sample builds, laboratory schedules, conformity work where applicable, production release and spare-part support.
A technically suitable design still needs a realistic route into volume production and long-term field support.
Why operators must be involved
For operators, power architecture affects deployment, service stock, customer support, field replacement and troubleshooting.
Clearer information and greater interoperability can simplify these processes, but only when the device, external power supply and cable are genuinely compatible. The transition should therefore be considered alongside product launches, installed-base planning, regional configurations, replacement units and service documentation.
Three assumptions worth challenging
USB-C automatically means USB Power Delivery. The connector and power-negotiation capability are related, but they are not interchangeable terms. The implementation must be defined and validated.
Higher wattage means a better solution. More available power does not confirm the correct voltage, transient response, cable compatibility, thermal behaviour or long-term suitability. The right-sized solution is the one that reliably meets the device’s real requirements.
There is no need to act until 2028. The application date is fixed, but engineering, testing and supply-chain lead times are not. Early mapping preserves options and gives teams time to qualify the complete power path properly.
The next step is controlled preparation
Regulation (EU) 2025/2052 has moved beyond being a future headline. It is now a product-planning issue for OEMs, operators and suppliers.
The practical response is to identify affected products, understand real power demand, validate the complete power path and build the supporting evidence while design and supply-chain choices remain open.
That creates a controlled route from legacy DC to USB-C where appropriate, without assuming every product requires the same solution.
The deadline is fixed. The quality of the transition is not.
