LOKITHOR JP400 12V Jump Starter with 150 PSI Air Compressor — 2500A Peak, Portable Power Bank

The JP400 combines high current starting capability and a digital air pump into a single, portable unit engineered for modern drivers. Designed to revive 12V batteries in vehicles up to 8.5L gas or 6.5L diesel, it adds a pressure-controlled inflator, USB power outputs, bright LED lighting and advanced electronics in a compact, award-winning chassis.

How quickly can the JP400 start my vehicle?

The unit delivers up to 2500A peak current with a BOOST function that automatically detects battery voltage and assists in recovering deeply drained batteries. It’s rated to start 12V engines up to 8.5L gasoline and 6.5L diesel even under extreme temperatures.

• 2500A peak power for fast cranking
• BOOST mode for low-voltage recovery
• Works from -4°F to 140°F operating range
• Smart clamps with self-identification for secure connection

Can I inflate tires and set an automatic cutoff?

Yes — the JP400 features a cordless 150 PSI air compressor with preset modes and auto shut-off. Choose the mode for cars, motorcycles, bicycles or balls, set your target pressure on the screen, and the inflator stops automatically when it reaches that value.

• 150 PSI maximum for cars and light trucks
• Four inflation modes selectable on-screen
• Auto shut-off at preset pressure to prevent overinflation
• Inflatable hose and nozzle adapters included

What safety and reliability features protect my vehicle and the device?

Safety is handled by an integrated Battery Management System (BMS) and ten built-in protections such as reverse-polarity, short-circuit and temperature safeguards. LOKITHOR’s CONNECTMAX technology also automatically compensates for poor clamp-to-terminal contact, improving starting reliability by detecting and adjusting for impedance.

• Ten protection types including spark-proof and over-current
• CONNECTMAX for improved clamp contact and starting performance
• High-rate 80C battery with ultra-low standby draw (~0.35mAh)
• Dual-sided ventilation and upgraded thermal design for longer life

How does the JP400 serve outside of jump starts?

The unit doubles as a portable power bank and emergency light. It provides dual USB ports for charging phones and small electronics, and a 300-lumen LED with flashlight, strobe and SOS modes that can run for extended periods.

• Dual USB outputs for phones, cameras and laptops
• 300-lumen LED light with three modes and up to 12 hours runtime
• Smart 4.15-inch LED screen shows voltage and tire pressure
• Up to 36 months standby readiness with efficient BMS

Who is this for: The LOKITHOR JP400 is aimed at drivers who want a single portable tool that covers jump-starts, tire inflation and emergency power. It’s ideal for owners of larger gasoline or diesel vehicles, roadside workers, weekend adventurers, and anyone seeking a compact, safety-focused solution for vehicle emergencies and outdoor use. The package includes the JP400 unit, jumper cables, inflatable hose, USB cable, three nozzle adapters, a storage bag and a user manual.
