"Look, no wires! This colorful E-Ink display is the first device I've seen that uses truly wireless power without contact."
Color E Ink displays were everywhere at ISE 2025, but this is the only one in the world that receives its power wirelessly.
During the digital signage exhibition at ISE 2025, several E Ink color monitors were presented, but the Wi-Poster stood out as the only one utilizing wireless power. This device is available in different sizes, ranging from 13 to 40 inches, and is the first functional product to use long-distance wireless power. An observer who saw it in action described it as "magical," a sentiment many agreed with.
Ori Mor, CEO and founder of Wi-Charge, explained that the use of wireless power allows companies to place the Wi-Poster anywhere, as it is virtually always powered. This means that images can be updated via Wi-Fi as many times as necessary, without the concern of connecting the device to a power source or needing to recharge batteries. Mor emphasized that over time, the costs of battery replacement can be significant, and that their wireless power solution can help businesses save money and reduce waste. Additionally, even with rechargeable batteries, there is expense and effort involved in keeping them charged.
Wi-Charge's wireless power system, called "AirCord," uses infrared to transmit up to 350 milliwatts of energy from a wall-connected transmitter to devices with a built-in receiver at a distance of up to 10 meters. A single transmitter can power multiple devices simultaneously, although each must have a line of sight to the transmitter. If something obstructs the line of sight, the flow of energy is interrupted, but it automatically resumes once the obstacle is removed.
In terms of safety, Mor assured that transmitting energy through the air is completely safe and has been validated by all global standards agencies, including IEC and CE in Europe, and FCC and FC in the U.S. As a Spectra 6 display device, the images from the Wi-Poster are visually striking, with rich and vibrant colors that are practically indistinguishable from paper, remaining visible even in sunlight. Mor demonstrated the image updating process, which took about 30 seconds.
Although E Ink is not suitable for video, Wi-Charge already has an LCD display powered by "Aircord" on the market called Wi-Spot, available in 7 and 9-inch sizes, primarily aimed at product-related advertising in the retail sector. This device is also equipped with motion sensors, enabling businesses to collect data on customer traffic and optimize their store layouts.
Wi-Charge also showcased a toothbrush holder and an Xbox controller that operate on wireless power, although these turned out to be prototypes and not products available for sale.
Currently, Wi-Charge has not revealed the pricing for the Wi-Poster, although they suggested that interested companies contact the company directly to discuss it.
