Capacitors take an infinitesimally lower amount of time to gather charge than batteries and tend to be generally lighter, i-Rocks is putting this fact to good use with its Quick Charging Wireless Mouse prototype showcased at the 2024 Computex. The device charges up to full in 5 minutes for 4-30 days of use, depending on the current. If you're in a hurry, just plug it in for a minute, and you can get through the day. Also, the capacitor is rated for 100,000 recharge cycles, compared to the 1,000 cycles that the lithium-ion batteries powering contemporary wireless gaming mice come with. The capacitor is lighter than batteries, and is exempt from the kind of travel and transport restrictions lithium-ion batteries have to deal with—you don't need to put this mouse in your carry-on, and can check it in at the airport. i-Rocks said that they plan to launch this mouse later this year. The company is also working on wireless keyboards based on capacitors.
