After the EU Laptop Charger Deadline, USB-C Becomes the Design Baseline

Key Takeaways

• The EU common charger rules now apply to laptops, making USB-C the default starting point for EU-bound portable designs, with USB PD required for covered devices charging above 15 W. 
• BOM impact concentrates on the PD controller, the cable, and the protection stack around the receptacle.
• The technical file ties the charging path's design, protection, and test data into the conformity case. 
• Upcoming EU regulations will target cables and wireless charging, with scope expansion beyond consumer electronics.

The Charging Port Decision Is Already Made

What changed on April 28, 2026? Laptops were added to the device categories under the EU Common Charger Directive, completing the initial regulatory phase-in. The rules of this directive apply to radio equipment categories with removable or embedded rechargeable batteries that use wired charging. The directive's rules first applied on December 28, 2024, to smaller devices such as phones, tablets, headphones, cameras, e-readers, keyboards, mice, earbuds, and several others. With laptops now included, USB-C compliance is the new design baseline.

Most major laptop OEMs transitioned their hardware before the April 2026 deadline, so current premium and commercial lines already commonly support USB-C charging. But now comes the harder part: standardizing USB-C charging behavior, packaging, and documentation across EU-bound SKUs. For example, the same connector is used across phones, wireless keyboards, and laptops, but each device places different demands on power delivery, protection, thermal design, and mechanical durability. Each device also requires its own conformity documentation.

Exceptions and Edge Cases

Older inventory is not grandfathered in. Devices that lack a USB-C charging port, or that use USB-C only for data without USB Power Delivery (PD) charging support, require review before they are placed on the EU market as new products. Some vendors also retain proprietary or magnetic connectors alongside USB-C, which is allowed when the covered device still supports the harmonized USB-C charging solution.

High-power devices like gaming laptops and mobile workstations are subject to an exception. According to Commission Notice 2024/C 2997, devices drawing more than 240 W can retain proprietary high-power connectors but must also support USB-C charging up to 240 W. A 330 W gaming rig, for example, can retain its barrel jack while also featuring a functional USB-C charging port.

Unbundling Affects Packaging and Docs

In addition to device-level requirements, charger unbundling changes what ships in the box and what the artwork must say. The rule, in force since the directive's first wave in December 2024, requires OEMs that bundle a charger to also offer the device without one, which makes a no-charger SKU standard for EU laptop lines. The European Commission estimates it saves consumers €250 million yearly and cuts e-waste by 980 tonnes annually.

What "Design Baseline" Looks Like in 2026

PD Controller Selection Has Moved Up the Architecture Stack

Standard Power Range (SPR) USB PD controllers, such as TI’s TPS25751, ST’s STUSB4500, and Renesas’ R9A02G011, support standard-power USB-C charging use cases up to 100 W.

Higher-power designs can move into PD 3.1 / Extended Power Range (EPR) parts and platforms, including Diodes’ AP33771C and AP33772S sink controllers, Renesas’ RAA489400 Type-C port controller, and Infineon’s EZ-PD^™ PMG1 family. The controller choice now constrains the rest of the power path, similar to how the MCU family choice constrains firmware architecture. 

Cable Specification Has Bifurcated

USB-IF discontinued certification of the 100 W USB-C-to-USB-C cable category back in December 2021. New certifications are either 60 W or 240 W, and the middle ground is gone. The 60 W cable requires no eMarker. The 240 W cable requires an EPR-certified eMarker, along with tighter creepage, a 53.65 V minimum functional voltage, and a 63 V minimum bypass capacitor rating. For OEMs bundling a cable, that eMarker is a procurement detail with compliance implications, since it communicates cable capability during PD negotiation. 

The Protection Stack Supports the Conformity Case

Electrostatic discharge (ESD), overvoltage protection (OVP), surge, and thermal protection choices now support the broader conformity case. The technical file should show how the USB-C charging path was designed, protected, tested, and documented, including the parts’ IEC 61000-4-2 ESD immunity and IEC 61000-4-5 surge immunity ratings. Protection parts such as ST’s TCPP series, including the TCPP01-M12, are designed for USB Type-C port protection, covering the Configuration Channel (CC) line, VBUS overvoltage, short-to-VBUS events, and ESD. 

Conformity Documentation Strategy

USB PD 3.1's EPR covers most laptop power profiles, keeping EPR specifications central to laptop design. The EU Conformity to USB-IF Specifications program, launched in 2024, provides OEMs and ODMs with a documentation path to show conformity to the USB specifications and IEC 62680 categories referenced by EU legislation. It supports the conformity package without requiring full USB-IF logo certification, keeping costs and timelines within reach for smaller vendors.

Packaging Artwork Is Engineering's Problem

Compliance extends to the artwork on the box. The directive requires the Annex Ia, Part III pictogram, in whichever format applies (charger included or not), plus the charging-capability label from Part IV, on packaging, in online product listings (near the price); the label also goes in the instructions. The label's power figures are engineering data, so updating the artwork means coordinating with marketing, mechanical, and procurement teams.

What’s Coming Next

The Common Charger Directive is now in its next review phase. Cable unbundling, scope expansion, external power supplies, and wireless charging are moving through separate EU review or rulemaking tracks, with an external power supply regulation already on the books for 2028.

Cable Unbundling Review

Under the amended Radio Equipment Directive (RED), the Commission has to report by December 28, 2026, on whether the unbundling rule should extend to cables. Consumer advocacy groups have pushed for the extension. If that extension is adopted, OEMs that currently bundle a USB-C cable in the box will need an additional no-cable SKU.

Ecodesign Rules Reach Chargers and Cables

Commission Regulation (EU) 2025/2052, adopted in October 2025, extends ecodesign requirements to external power supplies, wireless chargers, battery chargers, and USB-C cables, and will apply from December 14, 2028. For USB-C-to-USB-C cables, it requires compliance with the official USB specifications and a 60 W or 240 W power marking on each plug. Chargers and cables will carry their own regulatory requirements, alongside the device.

Wireless Charging Interoperability

Wireless charging is in a different situation. The Commission's stated assessment is that the wireless-charging market currently shows low fragmentation and a good level of interoperability among the dominant solutions, with no firm legislative proposal pending. The directive provides for future review as the technology matures, and Qi2 adoption across phones, earbuds, and small wearables will likely influence what any future harmonization step looks like. 

Scope Expansion

Additional rechargeable product categories are under review. The Commission's May 2025 supporting study examined whether common charger requirements should be extended to equipment the directive does not yet cover.

Designing with the New Baseline

The regulated path around the USB-C receptacle reads like a sourcing list because it is one: PD controllers, eMarker ICs, transient voltage suppressors, USB-C connectors, and EPR-certified cables, each now a BOM line item with compliance documentation attached. What separates teams designing under the new baseline is how early they see that list. Octopart surfaces lifecycle status, supplier alternatives, and stock across all five categories before the layout locks anything in.
