Product Highlights:
- The VX1 jump starter integrates six functions – car jump start, tire inflation, lighting, SOS warning, device charging, and 12V accessory start – based on an upgraded 2024 design meant to lead future market trends.
- This versatile battery jump starter packs multiple capabilities into one unit.

- The built-in air compressor has an LCD digital meter and tire pressure detection to automatically shut off at preset PSI/BAR/KPA values. Inflating an average car tire to 20 PSI takes around 3 minutes with the 150 PSI compressor, useful for bikes, balls, and inflatables too.
- The unique honeycomb heat dissipation design allows the VX1 jump starter to disperse heat more effectively, enhancing safety performance by 30% and extending service life by 50%. Its upgraded thermal engineering improves durability and safety.
- With 10 built-in protections against issues like overcharging, overcurrent, short-circuit, reverse polarity, and extreme temperatures, the VX1 allows easy and fast car starts in harsh -4°F to 140°F environments. Safety is the paramount priority in its design.
- The VX1’s LED lights offer Normal, Strobe, and SOS modes for emergencies, while the unit also functions as a portable power bank to charge USB devices via its port and provide 36 hours of high-brightness lighting. It combines an emergency light and mobile charging capabilities.
