LOKITHOR JC400 9-in-1 Battery Charger & Jump Starter – 2500A, 12V Portable Jump Box

Your all-in-one roadside companion

The LOKITHOR JC400 is a compact 9-in-1 device that blends a jump starter, battery charger, maintainer, trickle charger, desulfator, voltage detector, portable power bank, and an emergency LED light with a built-in compass. This palm-sized powerhouse fits neatly in a glove box or bag while offering a robust 2500A peak to jump 12V engines up to 8.5L gas or 6.5L diesel, and it remains capable across a wide temperature range from -4°F to 140°F, making it a versatile ally for daily drives and longer road trips.

Flexible power for many batteries and situations

Three selectable charging currents (0.75A, 1A, 2A) let you tailor charging to different battery chemistries and states. It supports 6V/12V regular batteries, 12V AGM, and 12V lithium packs, so you can keep cars, trucks, motorcycles, lawn equipment, boats, and more ready to roll. The FORCE CHARGING mode can even wake batteries down to 1 volt, helping you squeeze life from a deeply discharged pack.

• 9-in-1 versatility: jump starter, battery charger, maintainer, trickle charger, desulfator, voltage detection, portable power bank, LED light, and compass
• Three charging currents for precise maintenance: 0.75A, 1A, 2A
• Compatible with 6V/12V, AGM, and lithium batteries

Battery care, desulfation, and long-term health

The JC400 uses a 7-stage charging routine to maximize safety and efficiency. When full, it enters trickle/float mode to maintain battery health during winter storage. The built-in desulfator uses pulse current to address sulfation and stratification in older or idle batteries, potentially extending life.

• 7-stage charging with auto trickle/float maintenance
• Desulfator with pulse current rejuvenation
• ConnectMAX technology helps improve starting reliability by addressing terminal impedance

Safety, visibility, and on-the-go power

Engineered for safety, JC400 includes a battery management system and self-identifying clips with 10 protections against spark, reverse charge, over-charge, over-current, short-circuit, reverse polarity, and temperature extremes, among others. It doubles as a power bank with USB-A and USB-C outputs, and the 300-lumen LED light keeps you seen and oriented at night. A bright 4.15-inch display shows voltage and charging status in real time, while the compact shell resists sun, rain, dust, and drops. Standby on a full charge can reach up to 27 months.

• 10 advanced protections for safe operation
• Dual USB ports and a 300-lumen LED light for emergencies
• Real-time battery data on a bright display
