LOKITHOR JA300 Jump Starter with Air Compressor | 1500A, 150 PSI Tire Inflator, 24-Month Standby

Meet the LOKITHOR JA300: A 4-in-1 Power Companion

The LOKITHOR JA300 blends jump starting, tire inflation, portable charging, and a bright LED flashlight into a compact, ready-to-go device. It delivers up to 1500A peak power to help revive 12V engines in seconds, with enough capacity for multiple starts per charge. Its 45Wh battery is built for longevity, offering 1000+ charge cycles and a minimal standby drain that keeps it ready during storage.

Beyond starting your vehicle, the JA300 features an integrated air compressor that can reach up to 150 PSI, paired with a precise digital display. This setup lets you monitor tire pressure in real time, switch between PSI and BAR, and stop automatically when the target pressure is reached. Real-world use examples include inflating a common passenger tire from 0 to 35 PSI in roughly five minutes, with readings calibrated for consistent accuracy.

Safety You Can Rely On

Smart protection is built in: real-time voltage monitoring detects abnormal conditions, while a robust BMS guards against short circuits, over-current, reverse polarity, overheating, over-charge, and clamp-off events. UL-2743 certification adds an extra layer of safety for both you and your vehicle.

Designed for Heat Management

A three-vent heat-dissipation design (two sides, one bottom) enhances airflow to keep temperatures in check during longer use, helping sustain performance and extend service life.

4-in-1 Emergency Toolkit

In addition to jump starting, the JA300 serves as a portable power bank for USB devices and a dependable LED flashlight with Steady, Flash, and SOS modes for roadside needs. Quick-charging support (USB 3.0) helps you power up smartphones, tablets, and other small devices on the go.
