Key Features of MAXWIN K-CJS01
Battery-Less and Recharge-Free Design
Unlike traditional jump starters that rely on lithium batteries, the K-CJS01 incorporates a supercapacitor. This design means the device does not degrade when left unused, ensuring it is always ready for immediate use. Its long-term storage capability provides peace of mind, as it never needs to be recharged to maintain its readiness.

Instant Engine Start with Supercapacitor Technology
The K-CJS01 utilizes a powerful 2500F supercapacitor (composed of five 500F capacitors) to amplify the minimal residual power from a vehicle’s battery. This boosted power is then returned to the vehicle, allowing for an immediate engine start. This method ensures reliable operation even when the vehicle’s battery is severely drained.

High Current Output for Large Vehicles
With a peak current of 2000A, the K-CJS01 is capable of starting a wide range of vehicles. It supports gasoline engines up to 8L and diesel engines up to 6L, making it suitable for large vehicles such as Land Cruisers, Alphards, and various imported cars.

Quadruple Safety System
Prioritizing safety, the K-CJS01 employs a highly reliable capacitor-based system, which inherently carries almost no risk of ignition compared to lithium-ion alternatives. It is equipped with a quadruple safety system that includes reverse polarity protection, short circuit protection, overcurrent protection, and overheat protection.

Extreme Temperature Resilience
Designed for versatility, the K-CJS01 can operate in a wide temperature range from -40°C to 70°C. Unlike conventional jump starters that experience significant performance degradation below 0°C, this product has been tested and proven effective in extreme cold environments. This makes it an ideal tool for use in ski resorts, winter fishing trips, and emergency situations.

User-Friendly IPS LCD Monitor
The device features a high-brightness, high-visibility color IPS LCD monitor. This display allows users to quickly check the progress and voltage status, ensuring straightforward operation even for novices.

Integrated LED Light for Emergencies
An emergency LED light is built into the K-CJS01. This light can be used for illumination during night work or in dark areas, and it can also function as an SOS signal in emergency situations.
