Energous demos WattUp system that can wirelessly charge devices from 15 feet away
This router can power your devices wirelessly from 20 feet away — Wireless charging hasn't really set the world on fire. Since the Palm Pre first introduced us to the idea at CES 2009 …
Context & Ripple Effects
At CES 2015 Energous pitched WattUp as room-scale wireless power — devices charging from about 15 feet away. Two years later, the reality the company itself announced was far narrower: an FCC-approved Energous product that works from just three feet, debuting at CES 2017.
The gap between that promise and delivery is visible across the rest of the coverage: Qualcomm's answer to charging anxiety was speed over distance with Quick Charge 5, the NFC Forum standardized only 1-watt wireless charging for small devices, and by 2023 Wi-Charge's shipped system managed just 2-3 watts and demanded line of sight between transmitter and receiver.
First-order effects
- CES attendees in 2015 see a distance claim WattUp cannot ship: Energous' own later FCC filing caps its first product at three feet, so the 15-foot demo is a roadmap item, not a product spec.
Second-order effects
- Smartphone vendors facing the same battery-life pressure route around over-the-air power entirely, adopting wired fast-charging like Qualcomm's Quick Charge 5 rather than waiting on RF-based systems.
- Standards bodies hedge with modest, shippable specs — the NFC Forum's 1-watt standard gives accessory makers a certifiable path instead of betting on long-range claims.
Third-order effects
- If the pattern holds, true over-the-air charging never reaches phones and instead settles into niche fixed installations — Wi-Charge's line-of-sight, few-watt deployments for sensors and small devices are where the category actually lives.
The trend: Over-the-air wireless charging keeps being demonstrated at distances it can't commercially deliver, while mainstream charging progress comes from wired fast-charge and short-range low-power standards.
