WOLFBOX 4000A Jump Starter with 160PSI Compressor

This compact power pack from WOLFBOX combines a 12 V jump starter and a high-pressure air compressor so you can tackle flat batteries and low tyre pressure with a single handheld unit. It is aimed at drivers who want a portable emergency kit that also serves as a 88.8 Wh power bank for charging phones and tablets, while offering rapid USB-C charging and an integrated LED work light.

Key Points

The unit delivers a peak 4000 A starting current, which the manufacturer states is capable of jump-starting petrol or diesel engines up to 10 litres. The built-in air compressor reaches up to 160 PSI and is rated to inflate typical van and some light truck tyres quickly. A 65 W USB-C input/output shortens recharge time, and the device includes multiple USB-A outputs for charging smaller gadgets. The LED torch reaches around 400 lumens and has standard, strobe and SOS modes for roadside emergencies. According to the specification, the pack operates down to -20 °C and carries IP64 protection against dust and splashing water, adding resilience in poor weather.

Usage Recommendations

For jump-starting, attach the clamps to the vehicle battery following standard safety practice and ensure correct polarity. Use the compressor with the appropriate nozzle for the tyre valve and monitor pressure with the unit’s gauge; for a medium SUV tyre the manufacturer example suggests inflation times of roughly 1 minute 20 seconds from low pressure to highway-ready pressure. The fast-charge USB-C port allows the pack itself to be recharged in about two hours with a compatible charger, making it practical for regular top-ups between trips. Consider storing the pack in the boot in a padded bag to protect the casing and cables, especially if you travel on rough roads.

Positive Aspects

The combination of jump starter, 160 PSI compressor and a mobile power bank reduces the number of separate devices needed for vehicle emergencies. The rapid 65 W charge capability means less downtime before the pack is ready again. The robust LED lighting and selectable emergency modes improve visibility during night-time roadside situations. The pack’s cold-weather performance and IP64 rating offer added confidence in winter months, although extremely prolonged exposure to heavy rain should be avoided.

Note that while the 4000 A peak figure is the rated maximum, actual performance depends on battery condition and ambient temperature, and very large commercial vehicle engines exceed the stated 10 litre guidance.
