LOKITHOR JP400 12V Jump Starter with 150 PSI Air Compressor — 2500A Peak, Color LCD, for up to 8.5L Gas/6.5L Diesel

The LOKITHOR JP400 is a compact all-in-one 12V jump starter with a built-in 150 PSI air compressor, 2500 peak power and a smart LED display for safe, reliable roadside power and inflation.

Designed to pack multiple emergency functions into a pocket-friendly unit, the JP400 combines powerful jump-start capability with a cordless tire inflator, LED lighting and dual USB charging. It supports gasoline engines up to 8.5L and diesel up to 6.5L, uses a high-rate battery and an integrated battery management system for safe operation, and displays voltage and pressure in real time on a 4.15" color screen.

How quickly will the JP400 get my car started?

The JP400 delivers 2500 peak power and is engineered to jump-start most 12V vehicles — including up to 8.5L gasoline and 6.5L diesel engines — in seconds. CONNECTMAX technology improves clamp-to-battery contact for more reliable starts even with dirty terminals.

• 2500A peak starting power for heavy-duty starts
• Supports up to 8.5L gas / 6.5L diesel engines
• CONNECTMAX auto-impedance detection enhances clamp contact
• 10 safety protections via integrated BMS and smart clamps

Can I inflate tires and how does the auto-stop work?

The JP400 includes a cordless inflator capable of 150 PSI that offers preset inflation modes and an automatic shut-off when the target pressure is reached. Choose from modes for cars, motorcycles, bicycles or balls and watch pressure update on the LED screen.

• 150 PSI maximum pressure, fast inflation for car tires
• Four preset modes and manual pressure setting on-screen
• Auto-off stops inflation to prevent overfilling
• Includes hose and three nozzle adapters for versatile use

Is the JP400 safe to use and what protections are included?

Safety is built into the JP400 through a multi-layer battery management system and insulated smart clamps that self-identify connections. The unit provides ten protection features to reduce risks during jump-starting or charging portable devices.

• Spark-proof and reverse-polarity protection for safe clamp connections
• Over-current, over-voltage, and short-circuit protections
• Temperature protections for low and high operating conditions
• BMS reduces self-discharge; up to 36 months standby life

What additional tools and features help in roadside emergencies?

Beyond jump-starting and inflation, the JP400 doubles as a portable power bank and emergency light with multiple modes. The bright LED and dual USB ports make it a practical companion for nighttime situations and powering small electronics.

• 300-lumen LED with flashlight, strobe and SOS modes; up to 12 hours runtime
• Dual USB output powers phones, cameras, laptops and accessories
• 4.15" digital display shows battery voltage and tire pressure in real time
• Durable thermal design and ventilation for extended life and noise reduction

Who is this for? The LOKITHOR JP400 suits drivers, fleet operators and outdoor enthusiasts who want a compact, durable emergency unit that handles jump starts, tire inflation and device charging. It’s particularly useful for owners of larger gasoline or diesel vehicles, service technicians, and anyone who values an integrated, safe solution for roadside problems without carrying multiple tools.
