Real-Life Rescue: A Jump Starter That Saves the Day

The contractor was wrapping up a standard roadside tire change when he got an emergency call: an SUV was completely dead, stranded with kids inside, and one tire losing pressure.

Rather than bringing multiple tools, he pulled out the LOKITHOR JP400. In under 15 minutes:

• The SUV's battery was revived using the 2500A peak current BOOST function
• The leaking tire was reinflated with the 150 PSI smart air compressor

No tow truck. No delay. The family made it to their reunion safely and on time.

The JP400 Advantage: Performance That Speaks for Itself

Multi-Functionality That Fits in Your Glove Box

• Jump starts gas engines up to 8.5L and diesel up to 6.5L
• Smart air compressor with 4 inflation modes (cars, motorcycles, bicycles, sports balls)
• Emergency 300-lumen flashlight with 3 lighting modes (strobe, SOS, beam)
• Portable power bank with dual USB ports

At just 1.7 pounds, it combines multiple life-saving tools into one compact, glovebox-sized unit.

Proven BOOST Function for Dead Batteries

When a battery is completely drained, most jump starters fail. The JP400's BOOST mode overrides low voltage and automatically detects battery impedance, ensuring a jump-start every time.

Intelligent Inflation System with Auto-Shutoff

Flat tire? No problem. Just:

• Choose the appropriate mode (car, bike, etc.)
• Set your target PSI
• Let the JP400 handle the rest

It shuts off automatically once your set PSI is reached.

CONNECTMAX™ Technology Ensures Reliable Clamps

Battery terminals often develop rust or oxidation. LOKITHOR's exclusive CONNECTMAX system detects poor connections and compensates automatically, improving start-up performance by 30%.

Built-In Safety with 10 Layers of Protection

No need to be a mechanic. The smart clip system includes:

• Reverse polarity protection
• Spark-proof technology
• Overcharge, overvoltage, and short-circuit prevention
• Temperature and overload protection

Even beginners can jump-start safely.

Real-Time Diagnostics with Smart LED Display

The 4.15-inch digital display lets you:

• Monitor car battery voltage
• Track real-time tire pressure
• Select mode
• Gauge remaining battery life

All without guesswork.

Rugged and Durable in Extreme Conditions

From -4°F to 140°F, this device performs:

• Double balance beam at the base reduces vibration
• Dual-side ventilation boosts cooling efficiency by 50%
• Exterior is anti-aging, anti-shock, and fire-resistant

Research Supporting Jump-Starting Best Practices

1. Safety Protocols from Ohio State University

Ohio State’s Ohioline division recommends proper sequencing of cables, verifying voltage compatibility, and maintaining distance between vehicles. Jump-starting can result in sparks or electrical shorts if performed incorrectly. (Read the OSU Guide)

2. SLAC-Stanford: Boosting Battery Performance Scientifically

Researchers found that high current pulses significantly enhance lithium-ion battery life. This supports the JP400’s BOOST function, which delivers a controlled high-current pulse to revive dead batteries. (Read the SLAC research)

3. Iowa State University Battery Safety Guidelines

Battery systems must be used with certified insulation and surface protections. The JP400's design, smart insulation clips, and voltage control align with ISU’s best practice guidelines. (Iowa State Battery Safety)

Key Takeaway

The JP400 is more than a tool; it's peace of mind. Whether you're a commuter, off-road enthusiast, rescue technician, or road trip warrior, you won't find a more versatile, safer, or smarter device.

Its real-world success with emergency responders proves it’s not just a convenience—it's an essential.
