LOKITHOR JP400 12V Jump Starter with Air Compressor — 2500A Peak, Starts up to 8.5L Gas / 6.5L Diesel

The LOKITHOR JP400 is an all-in-one portable 12V jump starter and cordless air compressor that delivers 2500 peak power to start cars up to 8.5L gas / 6.5L diesel and inflates tires up to 150 PSI.

Compactly engineered for roadside emergencies and outdoor adventures, the JP400 combines jump-start capability, a built-in 150 PSI inflator, LED lighting, and dual USB power in a single rugged unit. Its smart digital display, CONNECTMAX impedance detection, and ten-layer safety protections make it a practical and safer choice for motorists, motorcyclists, and small-fleet operators who want a reliable multipurpose power tool that stores easily in a trunk or shed.

How quickly can the JP400 get a dead battery going?

The JP400 delivers up to 2500 peak amps and is rated to start 12V engines up to 8.5L gasoline or 6.5L diesel in seconds, even in harsh temperatures from -4°F to 140°F. Its smart clamp with CONNECTMAX improves contact and increases starting reliability, so weak terminal contact is less likely to prevent a start.

• 2500A peak output for heavy cranking power
• Supports up to 8.5L gas / 6.5L diesel engines
• Operates in extreme temperatures (-4°F to 140°F)
• CONNECTMAX impedance detection for better clamp contact

Can I inflate tires with this unit and how accurate is the pressure readout?

The JP400's integrated cordless air compressor provides up to 150 PSI and has preset modes for cars, motorcycles, bicycles, and balls. Use the bright 4.15" LED display to choose the inflation mode, set the target pressure, and watch the unit auto-shut off when the preset pressure is reached for consistent results.

• 150 PSI maximum inflating power
• Four preset modes with auto-off at target pressure
• Real-time pressure monitoring on 4.15" digital display
• Includes hose and three nozzle adapters for different valves

What safety features protect me and my vehicle?

Safety is layered into the JP400 with a built-in battery management system and a self-identifying clamp that prevents common user errors. The unit offers ten protections — from spark-proof and reverse-polarity to over-current and temperature protections — reducing the risk of damage when connecting to 12V batteries.

• 10 protection types including spark-proof and reverse-polarity
• Smart BMS for safe charge and discharge control
• Self-identifying clamp reduces incorrect connections
• High-density, flame-resistant housing for durability

What additional functions does the JP400 provide on trips?

Beyond jump-starting and inflation, the JP400 functions as a portable power bank and emergency light. It has dual USB ports for charging phones and small devices, a 300-lumen LED with three modes (flashlight, strobe, SOS), and long standby and run times to support roadside repairs and night-time visibility.

• Dual USB output for phones, cameras, and small laptops
• 300-lumen LED with flashlight, strobe, and SOS modes
• 12-hour LED runtime and up to 36 months standby
• Low idle self-discharge (approx. 0.35 mAh) for long storage

Who is this for: The LOKITHOR JP400 is ideal for drivers who want a compact, multi-function emergency tool — commuters, families, campers, motorcyclists, and small-truck owners. It suits anyone who values quick, reliable starts for larger engines, a cordless inflator with accurate presets, and an integrated power/lighting solution for roadside and outdoor use.
