【Car Troubles】No fear of dead batteries! A jump starter that doesn't need charging and lasts for 10 years

A jump starter that is not frequently used. Even if you prepare it, what if it doesn’t work when you really need it... I was worried about that. With a model that is battery-less and doesn’t require charging, it seems like it would be easy to use in case of an emergency.

No need for charging and safe with no lithium battery!

MAXWIN has developed a high-safety jump starter equipped with a supercapacitor that is "charge-free" and battery-less. Having one on hand makes long drives and car trips seem worry-free.

The K-CJS01 adopts a supercapacitor system without a lithium battery. It is equipped with five 500F capacitors, achieving a total capacity of 2500F. Due to its battery-less structure, it is less likely to degrade even if left unused, and regular charging management is unnecessary. You can eliminate the worry of “If I’ve left it in the car for a long time, will it be out of charge when I need it?”

The peak current required for engine starting is up to 2000A. It can support gasoline vehicles up to 8L and diesel vehicles up to 6L. It can cover a wide range of vehicles, including Land Cruisers, Alphards, and various imported cars. As a model compatible with 12V vehicles, powerful starting performance is ensured.

Conventional jump starters can suffer a significant drop in performance below 0℃. The K-CJS01 has a wide operating temperature range of -40 to 70℃, making it reliable not only for outdoor activities like skiing and winter fishing but also as an emergency tool during disasters. Additionally, the capacitance method, which is also used in commercial applications, greatly reduces the risk of ignition. It is equipped with various protective functions including reverse connection protection, short circuit protection, overcurrent protection, and heating protection.

A high-brightness color IPS liquid crystal display is used, allowing users to check voltage and progress at a glance. The operation design makes it easy for beginners to use without confusion. Furthermore, it is equipped with an LED light, which can be used not only as a working light in the dark or at night but also as an SOS light.
