NFC Forum unveils its Wireless Charging Specification, allowing 1 watt charging for smaller devices
Context & Ripple Effects
Wireless charging has long been a standards turf war: A4WP and PMA merged back in 2015 to consolidate against the dominant camp, and Energous spent years chasing FCC approval for at-a-distance charging. The NFC Forum is now entering the fray from a different angle — instead of competing on watts, its new Wireless Charging Specification targets just one watt, aimed at earbuds and smartwatches rather than phones.
The strategic logic is that small devices already ship with NFC chips for payments and pairing, so the spec reuses silicon that is already in the bill of materials. It sits at the opposite end of the power spectrum from the phone-focused arms race — Qualcomm's Quick Charge 5 pushing minutes-long refuels — and foreshadows the split that later shows up in the WPC's own Qi2 25W push for high-power phone charging.
First-order effects
- Device makers building earbuds and smartwatches gain a standards-backed option to charge over their existing NFC antenna, dropping a dedicated charging coil from the design.
Second-order effects
- The Wireless Power Consortium faces a low-end flank: accessory makers choosing NFC-based charging no longer need Qi certification for sub-1W products, pressuring the WPC's per-device licensing reach at the bottom of the market.
Third-order effects
- If the pattern holds, wireless charging standards stratify by device class — consortium specs owning phones while NFC owns wearables — echoing how the A4WP/PMA merger consolidated the field rather than leaving three rivals standing.
The trend: Wireless charging is fragmenting into power-tiered ecosystems, with standards bodies carving up the market by device size rather than fighting over a single universal pad.
