Dell unveils Pro 7 supercapacitor peripherals of the future

Dell unveils future-ready peripherals

Dell has introduced the Pro 7 wireless set (product code KM746), comprising a mouse and keyboard that do not use conventional rechargeable cells or disposable batteries. The devices instead rely on supercapacitors, enabling the peripherals to recharge in only a few seconds. According to the company, five seconds of charging provides around one day of use, while five minutes delivers up to one and a half months of battery life for the mouse and up to three months for the keyboard.

The key benefit of supercapacitors is their exceptionally fast charging and their near-total resistance to degradation over time. Unlike lithium-ion batteries, they are less vulnerable to wear and do not need periodic replacement in the way disposable batteries do. Supercapacitors are also regarded as safer in terms of fire risk. Dell has not yet announced the price of the Pro 7, but confirmed that US sales will begin on 16 April.

As CNews notes, interest in supercapacitors has also been growing in Russia in recent years, where new materials and components for these energy-storage systems are being developed. Russian researchers had previously proposed using unusual raw materials in supercapacitor manufacturing, including stems from giant hogweed.
