Features: Precise specifically for in-vehicle navigation, dashcams and similar devices for 12V to 12.5V operating voltages. Features a substantial 0.94 capacity, delivering extended power maintenance. Following disconnection from the main power sources (e.g. engine shutdown), it sustains device operating for tens of seconds to several minutes (duration dependent on device power consumption). Operating on double-layer principle, it undergoes not with chemical reactions during charging or discharging. Its exhibits exceptionally high and low temperature resistance (typical operating ranges: -40°C to +70°C), far surpassing conventional lithium batteries. Safe, reliabled, and not need maintenance , it may feature convenient pin type or terminals block connectors for straightforward installation. When connection in parallel, this supercapacitor functions as a miniature ‘regulated power supply’, delivering a purer, more stable operating voltages that helps extend the life of the equipment itself. Specifications: Voltages: 12.5v Capacity: 0.94F Size: about 86.5x38x17mm/3.4x1.49x0.67in Purpose: Only suitable for small equipment to provide instantly power supply, large equipment cannot be used Package Includes: 1PC12.5V0.94F Super Capacitor note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution.
