Mitsukin Shoji has boosted summer promotions for its SPEEDER-branded supercapacitor jump starters on Rakuten and Yahoo. Unlike standard lithium-ion units, these devices utilize supercapacitors to avoid ignition risks even in 70 degrees Celsius vehicle interiors. They require no pre-charging, as they can draw and boost residual battery power within 3 to 5 minutes to start a 12V or 24V engine. The line includes Ignic Pro, Ignic Max, and Ignic neo, offering maintenance-free safety and a service life exceeding 10 years. Sales are live during Yahoo's sale (June 4-7, 2026) and Rakuten's Super Sale (June 4-11, 2026).
