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

The LOKITHOR JP400 is a compact, multi-function 12V jump starter and 150 PSI air compressor that restarts 8.5L gas / 6.5L diesel engines, charges devices, and lights emergencies.

Engineered for roadside reliability, the JP400 combines a high-rate battery, digital display and CONNECTMAX clamp detection in a small, rugged package. It pairs a 2500-peak-power jump capability with a built-in tire inflator, LED lighting and dual USB ports so you can troubleshoot low battery situations and modest air needs without carrying multiple tools. The unit’s thermal design, battery management system and preset inflator modes make it practical for daily drivers, fleet vehicles and outdoor use.

How fast and powerful is the JP400 for jump starting vehicles?

The JP400 delivers 2500 peak amps and is rated to start 12V engines up to 8.5L gasoline or 6.5L diesel in seconds, even under challenging temperatures from -4°F to 140°F. An internal Battery Management System (BMS) and smart self-identifying clamps protect the unit and vehicle while optimizing output for a reliable start.

• 2500A peak power for quick crank and repeat starts.
• Supports large 8.5L gas / 6.5L diesel engines.
• Smart clamps with reverse-polarity, spark-proof and multiple protections.
• Operates in extreme temperatures (-4°F to 140°F).

Can this device inflate tires and how does the air compressor work?

The JP400 has a cordless 150 PSI air compressor with preset modes and auto-off functionality for cars, motorcycles, bicycles and sports balls. Select the inflation mode on the 4.15-inch LED screen, set the target PSI, and the inflator shuts off automatically when the preset pressure is reached.

• 150 PSI maximum for fast inflation of tires and inflatables.
• Four preset modes (cars, motorcycles, bicycles, balls) for quick setup.
• Auto-stop feature prevents over-inflation at set pressure.
• Includes hose and three nozzle adapters for versatile use.

What safety features and protections does it include?

Safety is central to the JP400’s design: an integrated BMS and smart clamp self-identification deliver ten types of electronic protections to minimize risk during use. The CONNECTMAX impedance detection improves clamp-to-terminal contact, increasing starting success when corrosion or poor contact is present.

• Ten protections: spark-proof, reverse-charge, over-charge, over-current, short-circuit, reverse-polarity and more.
• CONNECTMAX technology detects clamp impedance and boosts starting reliability by ~30%.
• Insulated clamps and rugged housing reduce user exposure to sparks and heat.
• Low self-discharge with ~36 months standby and 0.35mAh self-power consumption.

What else can the JP400 do during an emergency or outdoor trip?

Beyond jump-starting and inflating, the JP400 functions as a power bank and emergency light. Dual USB ports let you charge phones, cameras and small laptops, while a 300-lumen LED supports flashlight, strobe and SOS modes with up to 12 hours of light time.

• Dual USB output for phones, tablets, cameras and wearables.
• 300-lumen LED with three modes: steady, strobe, SOS for roadside signaling.
• Smart LED screen shows voltage and real-time tire pressure readings.
• Compact, high-density construction with improved heat dissipation and shock absorption.

Who is this for? The LOKITHOR JP400 suits drivers who want an all-in-one, portable roadside solution: owners of cars, trucks and SUVs with larger engines, fleet drivers, outdoor adventurers and anyone who prefers compact gear that covers jump starts, inflating, device charging and emergency lighting. It’s ideal when you need dependable starts, a quick tire top-up and power on the go without hauling separate devices.
