GOOLOO A3 2-in-1 Car Jump Starter with Air Compressor, 3000 A, 150 PSI
The GOOLOO A3 is a portable 12 V car jump starter with a built-in air compressor, able to start engines up to 9.0 L petrol and 6.5 L diesel. It offers 3000 A peak current, a BOOST function for deeply discharged batteries, a 150 PSI (35 L/min) tyre inflator with auto shut-off, an LED flashlight and USB outputs for phones and tablets. One device, five functions.
Description
The GOOLOO A3 combines several roadside essentials in a single body: a jump starter, a tyre inflator, a power bank, an LED flashlight and an SOS light. According to the manufacturer, one full charge is enough for up to 50 jump starts. The 3000 A peak current and the BOOST button help start 12 V vehicles with a heavily discharged battery.
The integrated compressor inflates up to 150 PSI (35 L/min) and offers 5 inflation modes (off-road vehicle, passenger car, bicycle, ball and user-defined), automatic shut-off at the preset pressure and switchable units (BAR / PSI / KPA). According to the manufacturer, a 205/55 R16 tyre (0–36 PSI) is inflated in under 7 minutes. A large LED display shows battery level, pressure units, mode, and current and preset values, and stays readable in bright sunlight.
The smart jumper cable has an LED indicator: green means a correct connection, red means reversed polarity. The unit has 10 protections, including short-circuit, overload and reverse-polarity protection. It operates from −20 °C to 60 °C, is rated for more than 1000 charge cycles and, according to the manufacturer, retains about 90 % charge after 24 months on standby.

Good to Know
- The unit cannot charge other devices while jump-starting.
- Recharge the unit at least every 3 months. Use the USB-C cable and a wall charger (charger sold separately).
- Do not store the unit for long periods in a vehicle where the temperature exceeds 60 °C, as this may damage the battery.
- After connecting the clamps, the LED indicator should light green (correct connection); red indicates reversed polarity. After pressing BOOST with a green light, start the engine within 30 seconds.
- When charging low-current devices (e.g. earbuds or smartwatches), the unit may switch off automatically if the current falls below 200 mA.
- Read the user manual (EN) before use. Bundles with extra accessories (e.g. with the GT160 inflator) are also sold; this description covers the standalone A3 unit.
