Why Choose the SPKSTAR SC12?
Traditional jump starters rely on lithium batteries that can degrade, swell, or become dangerous over time. The SC12 uses a supercapacitor design that is maintenance-free, ultra-safe, and built to last. It charges directly from your vehicle’s battery or a USB-C power source, then releases a powerful 1000A start-up current to crank engines up to 5.7L petrol and 4.0L diesel.
No pre-charging. No battery anxiety. No compromise on safety.
Step 1: Connect the EC8 clips cable to the jump starter and open the car engine compartment. Step 2: Connect the clamps to the car battery — red to positive (+), black to negative (-). Step 3: Start your car.
If the SC12 has been charged via USB-C or DC port to at least 90%, press and hold the power button for 3 seconds to enter force-start mode, then start your car within 30 seconds.
Otherwise, the SC12 will automatically charge itself. The OUT light flashes while charging. When fully charged, press your car ignition switch and the SC12 will automatically output power to start the car within 30 seconds.
Step 4: Remove the clamps and close the engine compartment.
