Chargifi was a UK technology firm that built a cloud-managed wireless charging network for commercial venues. Its system let operators remotely monitor, control, and monetize charging spots in restaurants, hotels, and stadiums. Chargifi did not just sell charging pads. It sold the software that made those pads visible and adjustable from a dashboard.
By late 2021, the organization had split into two entities. Its cloud-based wireless power management software was spun out as a standalone venture called Airfuel Alliance, focused purely on the software layer. The original hardware and core wireless charging assets were acquired by Energous Corporation, a semiconductor outfit specializing in GaN-based wireless power solutions. The deal closed in late 2021. The Chargifi brand, as a combined hardware-and-software operation, ceased to exist in that form.
Chargifi's technology differed from standard Qi charging in one fundamental way: it added a cloud management layer that turned a passive power port into an asset a venue could measure, control, and monetize. Major deployments spanned restaurants, hotel lobbies, conference centers, airports, and sports stadiums. Venues made money through free amenity-driven retention, paid sessions, and sponsored charging. The eventual split reflected a strategic conclusion that the software and the hardware had different economics and different growth trajectories.
What Chargifi's technology did that standard Qi charging did not
The limits of standard Qi
Standard Qi wireless charging is a physical protocol. A pad delivers power to a device placed on it. There is no network connection, no usage data, no way to know whether the pad is working unless a person tests it.
The cloud management layer
Chargifi added a management layer on top of that. Its network used a cloud backend to communicate with charging spots installed in furniture, tabletops, or walls. Each spot reported its status: online, offline, charging, idle. A venue operator could see, from a single dashboard, that a charger at table 14 had stopped working and send maintenance before a customer complained. The system also tracked how long each spot was used and by what device types, giving operators data they could use to justify the installation cost.
Beyond power delivery
The charging itself could still use Qi or other inductive standards. The difference was not in the power delivery. It was in the remote monitoring, the ability to push firmware updates over the air, and the option to require payment or a login before the charger activated. That combination turned a passive power port into an asset that a venue could measure and control.
Who deployed Chargifi's smart charging
Target venues and installation partners
Chargifi's target market was commercial indoor spaces where people sat for 30 minutes or longer: restaurants, hotel lobbies, conference centers, airports, and sports stadiums. The firm announced partnerships with furniture manufacturers and fit-out contractors who embedded the charging hardware into tables, counters, and seating areas during construction or renovation.
Three revenue paths for venues
The model for venues had three revenue paths. First, a venue could offer free charging as a customer amenity, using the data from the system to prove to corporate stakeholders that the investment drove longer dwell times or repeat visits. Second, a venue could activate paid charging, requiring a guest to scan a QR code and pay a small fee before power started flowing. The software handled the payment processing and split revenue with the venue. Third, the venue could sell sponsorship: a beverage brand could pay to make charging free for customers, with the Chargifi dashboard tracking impressions and delivering measurable return for the sponsor.
The GaN engineering partnership
Chargifi also partnered with Energous to develop charging solutions based on gallium nitride (GaN) technology. GaN components are smaller and more efficient than silicon equivalents, which mattered for embedding chargers inside furniture without creating heat or bulk. That engineering partnership gave Chargifi access to Energous's WattUp technology, which could deliver power over distance rather than requiring direct contact.
The business model for venue operators
The investment and the return
A venue operator considering Chargifi faced a capital expenditure: purchase the charging hardware, pay for installation, and subscribe to the cloud management software. The return on that investment came from three levers.
Lever one: retention and satisfaction
The first lever was customer satisfaction and retention. Chargifi's own materials cited data showing that customers who used in-venue charging stayed longer and spent more. The dashboard gave the operator a way to measure that effect, which helped when making the case to franchise owners or corporate procurement.
Lever two: direct revenue from paid sessions
The second lever was direct revenue from paid charging. The system allowed an operator to set a price per session or per minute, with payment collected via the guest's phone. Chargifi took a cut of each transaction. This model worked best in high-traffic locations like airports, where travelers had limited alternatives and a clear need to top up their devices.
Lever three: sponsored charging
The third lever was sponsored charging. A brand could cover the cost of the session in exchange for a branded landing page or a push notification. The venue earned a flat fee or a share of the sponsorship. Chargifi's dashboard tracked how many users saw the brand message, giving the sponsor a measurable return. This model was lighter for the venue: no per-transaction friction, and the guest got free power.
How Chargifi's strategy changed over time
Starting with hardware
Chargifi began as a hardware outfit. It designed and sold the charging spots themselves, and the cloud software was a feature that differentiated those spots from generic Qi pads. Over time, the team concluded that the software was the more valuable and scalable part of the operation.
Why software won
Hardware has inventory risk, supply chain complexity, and longer sales cycles tied to furniture replacement schedules. Software has higher margins, can be updated remotely, and can support any charging hardware that meets the communication standard. In 2021, Chargifi acted on that insight. It spun out its cloud management platform into a separate entity called Airfuel Alliance. The new venture would license the software to any hardware manufacturer, not just to venues using Chargifi's own pads.
Two pieces, opposite directions
The original Chargifi hardware operation, including the physical charging products and the engineering team behind them, was acquired by Energous Corporation. Energous was already a supplier of GaN-based wireless power components, and the acquisition gave it a set of finished products and existing venue relationships. The two pieces of the old Chargifi thus went in opposite directions: software became an independent platform venture, hardware became part of a semiconductor firm's product line.
The role of smart or cloud-managed power in the product's value proposition
What "smart" actually meant
The term smart wireless charging means little unless it is compared to the alternative: a dumb pad that does nothing but pass current. Chargifi's product was smart in four specific ways.
Observable and controllable
First, it was observable. Every charger reported its status to the cloud, and the dashboard showed a map of all chargers in a venue. An operator could see that a unit was offline before a guest ever touched it. Second, it was controllable. The system could disable a charger remotely, push a firmware update, or change the pricing model without a site visit.
Measurable and monetizable
Third, it was measurable. The system counted sessions, duration, device types, and failed charging attempts. That data fed into operational decisions and into the sponsorship revenue model. Fourth, it was monetizable. A dumb pad cannot charge a fee, show a sponsor's logo, or limit access to loyalty program members. Chargifi's network turned the act of charging into a transaction or a marketing touchpoint. That was the core value proposition for venue operators: the charger was not a cost center but a revenue-generating asset with a measurable return.
The split confirmed the thesis
The separation of software from hardware, completed in late 2021, confirmed that the firm believed the smart layer was the long-term play. The hardware remained necessary, but it was increasingly commoditized. The differentiation lived in the cloud.
What happened to Chargifi as a corporate entity
The end of the combined entity
Chargifi as a combined hardware-and-software operation ceased to exist in late 2021. The corporate entity split along product lines. The cloud management platform was spun out as Airfuel Alliance, a new venture focused entirely on the software layer. The hardware assets, including the physical charging products and the associated intellectual property, were acquired by Energous Corporation.
The Energous acquisition
The acquisition by Energous was announced in late 2021. Energous, a publicly traded US semiconductor firm, had been working with Chargifi on GaN-based wireless charging solutions. The deal gave Energous a ready-made product line and a set of commercial deployments in restaurants, hotels, and stadiums. It also gave Energous the engineering team that had built those products. The financial terms of the acquisition were not disclosed in the announcement.
Where the pieces landed
The Airfuel Alliance spinout continued to operate independently, licensing the software platform to hardware manufacturers and venue operators. The Chargifi brand, as of December 2023, was no longer used by either entity. The hardware lives inside Energous's product portfolio. The software lives inside Airfuel Alliance. The original organization, which had tried to sell both as a single solution, concluded that the two lines had different economics and different growth trajectories. The split was the final strategic move of Chargifi as an independent entity.
