GYS Batteryless Booster Gyscap 24v
GYS Heavy-Duty 24V Supercapacitor Jump Starter for Commercial Vehicles
The GYSCAP 24V Batterless Booster is an advanced, battery-free jump starter engineered for heavy-duty 24V vehicles including HGVs, buses, agricultural and construction equipment. Built with 10 high-performance supercapacitors (3,000 F each), it delivers 2,500A cranking power and up to 10,000A peak output for instant, reliable starts. Unlike traditional boosters, it contains no internal battery, offering an exceptional 1,000,000 charge/discharge cycles and long-term reliability even after extended storage. Fully autonomous, it charges directly from a running vehicle, via cigarette lighter socket, or through a compatible power supply. Designed for demanding site conditions, it operates in extreme temperatures from -40°C to +60°C. The SMART STARTER MANAGEMENT SYSTEM ensures protection against reverse polarity and short circuits, while the integrated digital display provides accurate voltage monitoring and capacitor charge status for maximum operational safety.
