Humavox, an Israel-based venture firm, is developing a cup-shaped wireless charger that can charge multiple devices placed in it.

The charger was exhibited at Mobile World Congress 2016, which took place from Feb 22 to 25, 2016, in Barcelona, Spain.

The charger can charge low-power devices such as bracelet-like activity meters and hearing aids. Currently, it can transmit 1W (200mA, 5V) of electricity, but Humavox plans to increase the capacity to 2.5W (500mA, 5V). It adopted a method that transmits electricity by using wideband waves. The frequency can be set within a range from 2.1G to 5.8GHz in accordance with customer needs and standards adopted in each country.

Humavox is planning to license the technology but has no plan to develop IC chips in house. The company is already under negotiation with some companies.

"We expects that products using our technology will hit the market in 2017, starting from the medical field," Humavox said.
