Frequently Asked Questions (FAQ)
What if the jump starter fails to start the car?
Check whether the positive and negative connections are correct and free of looseness Check if the battery is faulty. Using a battery tester, if the voltage of a 12V car battery is below 5V or the voltage of a 24V car battery is below 10V, it is recommended to disconnect the cable lugs from the positive terminal of the battery, clamp the positive terminal onto the cable lugs, and then try to start the car.
How many times can it be used after fully charging?
The supercapacitor model uses residual power from the car battery to start instantly, ready in minutes. Therefore, the number of times it can start after a full charge is not a standard for measuring product quality. The product has a 30-second ignition interval for each start, and it will consume around 15% of the power for each start, which means you just need to wait about 1 minutes for another start.
How does the SC24 differ from conventional lithium-ion jump starters?
Unlike lithium-ion units, the SC24 features a battery-free supercapacitor setup. It requires no regular maintenance or long charging cycles, operates reliably in extreme temperatures ranging from -40°C to +70°C without risk of fire or thermal runaway, and delivers over 100,000 cycles with a 10-year lifespan.
What vehicle engines are compatible with the SC24?
The SC24 supports both 12V and 24V systems. It is universally compatible with gasoline engines up to 6.8L and heavy-duty diesel engines up to 16L displacement, including commercial semi-trucks, tractors, buses, RVs, passenger vehicles, and industrial machinery.
Can the SC24 be recharged via USB Type-C?
Yes. In addition to recharging directly from vehicle battery terminals via EC8 clips in about 6 minutes, the unit also supports rapid charging via USB-C (PD 140W max), achieving a full charge in roughly 7 minutes using a compatible power source.
Is the SC24 safe to leave inside a vehicle under direct sunlight?
Yes, because it contains no chemical lithium elements, the device is completely safe against overheating, swelling, explosion, or spontaneous combustion, even when stored inside hot car cabins or during freezing winter weather.
