Dell unveils next-generation Pro 7 peripherals with supercapacitors

Dell unveils next-generation peripherals

Dell has introduced the Pro 7 wireless set (catalogue number 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 be charged within seconds. According to the company, five seconds of charging provides roughly a 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 principal benefit of supercapacitors is their exceptionally fast charging and their near-total resistance to degradation over time. Compared with lithium-ion batteries, they are less affected by wear and do not need routine 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 said US sales will begin on 16 April.

As CNews notes, interest in supercapacitors has also been increasing in Russia in recent years, with new materials and components for these energy-storage systems under development. Russian researchers have previously suggested using unconventional raw materials in supercapacitor manufacturing, including giant hogweed stems.
