Overview:
On November 24, 2025, the European Commission officially adopted and issued Commission Regulation (EU) 2025/2052, introducing mandatory eco-design requirements for external power supplies, wireless chargers, universal portable battery chargers, and USB Type-C cables.
It is reported that over 400 million external power supplies (EPS) are sold annually in the EU market. The regulation aims to significantly reduce electronic waste and improve energy efficiency. By 2035, with the mandatory implementation of the new rules, approximately 3% of the total energy consumption during the EPS lifecycle is expected to be saved (equivalent to the energy used by about 140,000 electric vehicles in one year).
Additionally, the regulation not only sets higher energy efficiency standards for EPS but also introduces new interoperability requirements. For example, all USB chargers sold in the EU market must be equipped with at least one USB Type-C port and use detachable cables. These requirements will complement the EU Common Charger Directive, accelerating the full unification of charging interfaces for consumer electronic devices.
Part 1: Effective and Enforcement Dates
Effective Date: December 14, 2025
Transition Period: December 14, 2025 – December 14, 2028
During this period, products compliant with the new regulation will be deemed to meet the requirements of the old regulation (EU) 2019/1782.
Enforcement Date: December 14, 2028, replacing the old regulation (EU) 2019/1782.
For EPS with a nominal output power exceeding 100 W via USB-PD ports, the energy efficiency requirements of the old regulation (EU) 2019/1782, Annex II will continue to apply until December 14, 2030.
For EPS intended as spare parts (e.g., clearly labeled "External power supply for spare parts only" on packaging and a freely accessible website), certain provisions of the old regulation (EU) 2019/1782 will remain applicable until December 14, 2033.
Part 2: Key Revisions
Revision 1: Expanded Scope of Products
The old regulation (EU) 2019/1782 only covered external power supplies, while the new regulation extends control over the entire "charging ecosystem" of electronic devices such as smartphones and tablets, including:
External power supplies (updating the definition by removing the 250W maximum output power limit);
Charging docks (e.g., robot vacuum charging bases) that meet the EPS definition;
Wireless chargers and charging pads;
Universal portable battery chargers;
USB Type-C cables.
Revision 2: Added Interoperability Requirements
As a key supplement to the EU Common Charger Directive, the new regulation introduces additional interoperability requirements. For interoperable power adapters, the following must be met:
Must be equipped with at least one USB Type-C or USB-PD port;
The operation of USB Type-C and USB-PD ports must be independent of any other output ports, unless they are USB-PD ports sharing output power;
The maximum rated output power must be provided via the USB Type-C or USB-PD port;
The USB Type-C or USB-PD port must not have a hardwired output cable.
Cables must be detachable from the power supply to prevent the entire unit from being discarded due to cable damage.
Revision 3: Enhanced Energy Efficiency Standards
While the old regulation (EU) 2019/1782 already imposed strict energy efficiency requirements, the new regulation (EU) 2025/2052 further tightens these standards:
Added efficiency limits for EPS at 10% load;
Added standby power consumption requirements for wireless chargers;
Further tightened idle power consumption limits for EPS;
Further improved efficiency limits for EPS.
Revision 4: Supplemental Measurement and Calculation Requirements
The new regulation (EU) 2025/2052 provides additional clarifications on testing standards and conditions, primarily:
Specified the output measurement location for EPS USB Type-C and USB-PD ports and introduced a cable resistance correction factor;
Defined the test cable length and cross-sectional area for EPS ports other than USB Type-C or USB-PD;
Required dynamic EPS to be tested under load conditions ensuring power output;
Added surge testing requirements for interoperable EPS.
Revision 5: Labeling Requirements
As a key supplement to the EU Common Charger Directive, the new regulation introduces additional labeling requirements:
Interoperable external power supplies: Must display the following "Common Charger" logo on the product itself, packaging, and instructions:
Height requirements: When affixed to the nameplate, the height (A) must be at least 5 mm; when affixed to the housing, packaging, or instructions, the height (A) must be at least 7 mm.
Interoperable external power supplies: Each USB Type-C and USB-PD port must be labeled with its maximum output power. For USB-PD ports sharing output power, they must also graphically indicate the shared maximum total output power. The font height must be no less than 2.56 mm.
USB Type-C cables: Must clearly mark the maximum supported power (60W or 240W) on both plug molds, with the font height of "60" or "240" no less than 1.2 mm and the letter "W" no less than 0.6 mm
