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

The LOKITHOR JP400 is a compact 12V jump starter with an integrated 150 PSI air compressor and 2500 peak power designed to revive cars up to 8.5L gas / 6.5L diesel quickly and safely.

The JP400 combines a high-rate battery pack, a digital control panel and multiple safety systems in a small footprint so you can jump-start a vehicle, inflate tires and power devices from one portable unit. Built for roadside emergencies and outdoor use, it balances powerful starts with smart protections and a user-friendly LED display that reports voltage and pressure in real time.

How quickly can JP400 start a stalled car?

JP400 delivers 2500 peak amps and supports vehicles with engines up to 8.5L gasoline or 6.5L diesel. Its CONNECTMAX impedance detection and BMS help improve contact and increase starting reliability under varied conditions.

• 2500 peak power for rapid cranking
• Compatible with most 12V car and truck batteries
• CONNECTMAX boosts clamp-to-battery performance by detecting impedance
• Works in extreme temperatures from -4°F to 140°F

What does the built-in air compressor do and how easy is it to use?

The integrated cordless compressor provides up to 150 PSI to inflate tires, motorcycle wheels, bikes and sports balls. A preset mode with auto shut-off stops inflation at the target pressure so you won’t overinflate.

• Four inflation modes: cars, motorcycles, bicycles, balls
• Digital pressure monitoring on the 4.15" LED screen
• Auto-off when preset pressure is reached
• Quick inflation—designed to fill typical car tires in minutes

Is JP400 safe to connect and operate on my vehicle?

Safety is prioritized with a battery management system and smart self-identifying clamps that reduce user error. Multiple protections minimize risk from reverse polarity, sparks, over-current and temperature extremes.

• 10 protection types including spark-proof and reverse-polarity protection
• Insulated clamps and BMS to prevent unsafe connections
• Low self-discharge for long standby—up to 36 months
• Thermally managed housing for better heat dissipation and longer life

What else can this unit power and how long will the light run?

Beyond jump-starting and inflating, JP400 functions as a power bank with dual USB outputs for phones, cameras and small electronics. A 300-lumen LED offers flashlight, strobe and SOS modes for emergencies, with extended runtime at lower brightness.

• Dual USB ports to charge phones, laptops (via correct cable), cameras and wearables
• 300-lumen LED with flashlight, strobe and SOS modes
• LED light runtime up to 12 hours depending on mode
• Low self-power loss (approx. 0.35mAh) for long shelf life

Who this is for: The LOKITHOR JP400 is ideal for drivers who want a single compact tool for jump-starts, tire inflations and emergency charging. It’s especially useful for roadside preparedness, fleet vehicles, outdoor adventurers, and anyone who prefers an easy-to-read digital interface and enhanced safety features without carrying separate devices. The included accessories—jumper cables, hose, adapters and storage bag—make it plug-and-play for everyday use and travel.
