LOKITHOR JA300 1500A Jump Starter & 150 PSI Air Compressor — 7.0L Gas / 4.5L Diesel, 45Wh Power Bank

The LOKITHOR JA300 is an all-in-one emergency power and air solution that jump starts 12V vehicles up to 7.0L gas/4.5L diesel and inflates tires with a built-in 150 PSI compressor.

Designed for drivers who want a single portable unit to handle dead batteries, low tire pressure and small device charging, the JA300 combines a 1500A peak jumper, a turbocharged tire inflator, a 45Wh power bank and a bright LED flashlight into one rugged, safety-focused tool. It pairs high output performance with long battery life and multiple protections so you can respond confidently to roadside situations without carrying separate gadgets.

How quickly will the JA300 restart my car and which engines does it support?

The JA300 delivers up to 1500 amps peak current, allowing most 12V vehicles to restart within 1–3 seconds. It supports gasoline engines up to 7.0L and diesel engines up to 4.5L, making it suitable for sedans, SUVs and many light trucks. With a capacity for about 30 jump starts per full charge, it’s ready for repeated use over longer trips.

• 1500A peak current for fast cranking in 1–3 seconds
• Compatible with gas engines ≤7.0L and diesel ≤4.5L
• Roughly 30 jump starts per full charge under normal conditions
• 45Wh premium cells rated 1000+ cycles for long service life

What does the built-in air compressor do and how accurate is it?

The JA300’s integrated turbocharged inflator reaches up to 150 PSI and pushes 35 L/min airflow, so it handles common passenger tires quickly and accurately. A digital pressure sensor with professional calibration maintains ±1% accuracy, and a preset auto shut-off prevents over-inflation. Unit selection between PSI and BAR and quick inflation times make roadside tire care straightforward.

• Max 150 PSI, 35 L/min airflow for fast fills
• Inflates a 195/65R15 tire 0–35 PSI in about 5 minutes
• Digital display, unit switching (PSI/BAR) and auto shut-off
• Professional ±1% pressure calibration for reliability

How does the JA300 protect me and my vehicle during use?

The unit includes an advanced battery management system and multiple safety safeguards to reduce risk when jump starting or inflating. Real-time voltage monitoring warns of abnormal conditions and the system defends against short-circuit, over-current, reverse polarity, over-temperature, over-charge and clamp-off scenarios. The JA300 is UL-2743 listed for enhanced safety assurance.

• Real-time voltage monitoring alerts abnormal conditions
• Comprehensive BMS protections for electrical faults and misuse
• UL-2743 certification for industry-recognized safety
• Sturdy clamps and clamp-off protection for user safety

What additional functions and practical features does it offer?

Beyond jump starting and tire inflation, the JA300 works as a portable power bank and flashlight, making it a true 4-in-1 emergency tool. It supports fast USB charging for phones and tablets and offers a 300-lumen LED with steady, flash and SOS modes for visibility at night. The thermal design uses three large vents to improve heat dissipation and extend continuous operation time.

• USB fast charge input/output (5V/3A; 9V/2A) for devices
• 300-lumen LED flashlight with Steady/Flash/SOS modes
• Three-vent cooling to increase heat dissipation by up to 75%
• Compact, portable design for trunk or garage storage

Who is this for: The LOKITHOR JA300 is ideal for commuters, road-trippers, rideshare drivers and anyone who wants dependable roadside preparedness without multiple devices. It suits owners of cars, SUVs and light trucks who want a safe, multi-function unit with strong jump-start capability, accurate inflation, and device charging — especially useful for families, fleet operators and travelers who value long battery life and certified safety.
