Features
● Cold-Weather Operation
Supercapacitor jump starters compensate for the reduced discharge capability of traditional batteries in freezing temperatures. The Grepow Supercapacitor Emergency Jump Starter can reliably start vehicles in extreme cold as low as -40°C. With an operating temperature range of -40°C to -50°C, this 24V ultra-low-temperature jump starter ensures effortless starts—whether in blizzards or scorching summer heat.
● Multiple Starts Without Recharging
Unlike conventional supercapacitor jump starters, Symbo’s 24V Supercapacitor Emergency Jump Starter combines supercapacitors and batteries, significantly increasing the number of consecutive starts. No waiting for recharging—ideal for situations requiring repeated ignition attempts.
● High Energy Density
Compared to supercapacitor-only jump starters, Symbo’s 24V Supercapacitor Emergency Jump Starter (with integrated battery) overcomes the low energy density of pure supercapacitors. This is especially critical when:
A single start demands higher energy, or The vehicle has significant parasitic drain, which would quickly deplete a supercapacitor alone.
● Heavy-Duty Supercapacitor Jump Starter
Symbo’s proprietary supercapacitor technology ensures longer lifespan compared to traditional lead-acid battery jump starters. Under normal use, it delivers over 100,000 cycles.
● Powerful 24V Supercapacitor Jump Starter
With a peak current of 2100A, Symbo’s jump starter can ignite most gasoline engines and diesel engines up to 8.0L within minutes. Perfect for emergency starts in:
Trucks, mining vehicles, tractors, RVs
Snowmobiles, heavy machinery, and specialized equipment
