• Supports up to 8.5L gas / 6.5L diesel engines
• Operates from -4°F to 140°F for wide environmental use

What does the built-in air compressor do and how easy is it to use?

The cordless compressor delivers up to 150 PSI and offers four preset modes for cars, motorcycles, bicycles and balls. Choose the mode and set the target pressure on the LED screen; the unit automatically stops when the preset pressure is reached, preventing over-inflation.

• 150 PSI maximum flow for fast inflation
• 4 preset inflation modes and auto-off shutoff
• Includes hose and multiple nozzle adapters for different valves

How does JP400 protect my vehicle and my device while jumping or charging?

Safety features are built into both the clamps and the internal battery management system to reduce user error and protect connected electronics. The JP400 includes ten protection modes such as reverse-polarity, short-circuit and over-current safeguards, plus a smart self-identifying clamp to prevent sparks and incorrect hookups.

• 10 protection types including spark-proof and reverse-polarity
• Integrated BMS and self-identifying clamp for safe connection
• Low self-discharge and standby capability up to 36 months

What handy extras and usability features does it offer?

The JP400 doubles as a portable power bank and emergency light, making it useful beyond vehicle starts. A 4.15-inch LED display shows battery voltage and tire pressure in real time while dual USB ports power phones, cameras and small laptops; the 300-lumen LED provides flashlight, strobe and SOS modes.

• 4.15-inch smart LED screen for voltage and pressure readouts
• Dual USB output for charging mobile devices and accessories
• 300-lumen LED with three modes for roadside visibility
