EU law mandating universal chargers for devices comes into force

Original Article ↗ Hacker News Discussion ↗

Scope and Technical Details of the EU Rule

  • Law targets “radio equipment” under 100W. Many commenters note USB Power Delivery (USB‑PD) is explicitly required for devices that do wired “fast charging” (>5V, >3A, >15W).
  • Proprietary fast‑charge protocols are allowed, but they must support full USB‑PD functionality at least as well as the proprietary mode.
  • The baseline 5V/slow charging remains allowed; fast‑charge behavior is constrained by PD rules.
  • Separate EU “Ecodesign” regulation is expected to deal with charger-side behavior (efficiency, PoE, etc.), not just device ports.

Innovation vs Regulation

  • Critics worry mandating USB‑C will freeze connector innovation and create regulatory capture: only big firms will have the lobbying power to update the law when a better standard appears.
  • They point to slow or awkward evolution of other EU rules (e.g., cookie banners, data protection, self‑driving constraints) as evidence that “laws don’t get updated quickly.”
  • Supporters counter that:
    • Previous EU pressure already pushed micro‑USB, then allowed migration to USB‑C.
    • Laws can reference evolving standards (e.g., newer EN/IEC versions).
    • Market “left alone” did not converge; only Apple resisted USB‑C.

USB‑C / USB‑PD Practicalities

  • Many users want the mandate extended to more DC devices (routers, switches, small appliances) to eliminate barrel‑jack “wall warts.”
  • Discussion of PD quirks:
    • Fixed‑voltage PD‑to‑barrel “trigger” cables often fail if a charger doesn’t support certain voltages (e.g., 12V).
    • PD 3.0’s Programmable Power Supply (PPS) can request 3.3–21V in fine steps, which partially solves this, but support varies in the wild.
    • Mis-implemented USB‑C (e.g., missing CC pull-downs) leads to devices that only charge via A‑to‑C cables.
  • Proprietary fast‑charge systems (e.g., SuperVOOC) are debated: some praise thermal behavior; others argue PD PPS can match them and that vendor lock‑in is the real motive.

Batteries and E‑Waste

  • Many believe chargers are a smaller e‑waste issue than non‑replaceable batteries.
  • There is strong support for upcoming EU rules requiring “readily removable” portable batteries by ~2027, though “readily” and water resistance details are debated.
  • Arguments:
    • Pro: dramatically extends device life; aligns with circular‑economy goals.
    • Con: complicates waterproofing, adds cost/volume, increases risk from bad third‑party cells.

User Experience, Apple, and Cables

  • Mixed views on Lightning vs USB‑C: Lightning seen as mechanically robust and well‑controlled; USB‑C praised for power/data capabilities but criticized for fragile/loose ports and confusing cable capabilities.
  • Anecdotes about Apple devices refusing to fast‑charge with some third‑party cables raise suspicions of “malicious compliance,” though others report no issues and point to wattage or signaling differences.
