Wi-Charge Shuts Down: Wireless Power Pioneer Ends Operations

What happened to Wi-Charge?

Wireless power transmission pioneer Wi-Charge has ceased operations, according to an announcement by founder and chief executive Ori Mor on LinkedIn. The company, which developed room-scale wireless power technology using infrared laser beams, had targeted applications in digital signage and retail environments. Mor described the decision as emotional, marking the end of a venture that sought to eliminate power cables for low-energy devices across commercial spaces. The closure was reported by invidis, a German trade publication covering the professional AV and digital signage sectors.

How did Wi-Charge's technology work?

Wi-Charge's system transmitted electrical power wirelessly across distances of up to several meters using focused infrared light. A ceiling-mounted transmitter would locate compatible receivers — embedded in devices such as electronic shelf labels, small digital signs, or sensors — and deliver up to a few watts of power without physical connections. The technology aimed to solve installation challenges in retail settings where running power cables to every display location proves costly or impractical. Unlike inductive charging pads that require close proximity, Wi-Charge's approach allowed for greater device mobility within a defined coverage zone.

Where was the technology deployed?

The company found niche adoption in retail environments, particularly for edge-shelf displays and electronic shelf labels that require minimal power but benefit from cable-free placement. These low-power applications aligned with Wi-Charge's output capabilities, which were suited for devices consuming milliwatts to low single-digit watts. Digital signage integrators explored the technology as a way to reduce installation complexity in stores where adding electrical outlets at every shelf edge would be prohibitively expensive. The company also demonstrated proof-of-concept installations for smart building sensors and other internet-of-things endpoints.

Why did the company close despite its technical achievements?

While Wi-Charge demonstrated technically viable wireless power delivery, the business faced challenges scaling beyond pilot projects. The digital signage and retail technology markets have seen consolidation, with many integrators opting for battery-powered or power-over-ethernet solutions that leverage existing infrastructure. Competing wireless power standards — including resonant inductive and radio-frequency approaches — also vied for the same low-power device ecosystem. The company's closure reflects broader difficulties in commercializing room-scale wireless power at a price point and reliability level that displaces wired alternatives for mainstream deployments.

What does this mean for wireless power in digital signage?

Wi-Charge's exit leaves a gap in the room-scale wireless power category, though the underlying concept retains interest for specific use cases. Retailers continue to seek ways to power proliferating shelf-edge displays and sensors without extensive electrical work. Alternative approaches, including improved battery chemistries, energy harvesting, and power-over-ethernet standards, remain the practical choices for most deployments today. The shutdown underscores that technical feasibility alone does not guarantee market adoption when installation economics and ecosystem maturity favor incumbent solutions.
