A flat battery or a flat tyre on a deserted road is not a situation anyone plans for. The GOOLOO A3 exists for exactly that moment. This compact, all-in-one emergency power unit combines a 3000A peak-current jump starter, a 150PSI digital air compressor, and a 100-lumen LED torch into a single device weighing approximately 1kg. It sits in your boot, stays charged for up to 24 months without a top-up, and works across cars, motorcycles, RVs, boats, and any 12V vehicle. No second car needed. No roadside assist call required. The lithium polymer cell is rated for over 1,000 charge cycles, which means this is a one-time purchase built to last years of real-world use rather than a disposable emergency item. Two-way fast charging keeps the unit ready quickly and doubles as a power bank for phones and accessories when you are not jump starting a vehicle.
Key Features and Benefits
- 3000A peak current starts flat batteries in petrol engines up to 9.0L and diesel engines up to 6.5L, covering the vast majority of passenger cars, SUVs, utes, vans, and light commercial vehicles
- Built-in 150PSI digital air compressor with programmable auto shut-off inflates tyres to an exact target pressure without over-inflation risk or manual monitoring
- Smart circuitry detects and recovers deeply discharged batteries that are too flat to trigger a conventional jump starter
- 12,000mAh lithium polymer cell with a 1,000-plus cycle lifespan delivers consistent peak output over years, not months
- Two-way fast charging accepts 10W input to recharge the unit and delivers 12W USB output to charge phones, dash cams, and other devices simultaneously
- Integrated 100-lumen LED torch operates in three independent modes: steady illumination for roadside repairs, SOS flash for emergencies, and strobe
- 24-month standby capacity means the unit retains usable charge after two years in storage without monthly maintenance charging
- Six-layer built-in protection covers reverse polarity, short circuit, over-current, over-charge, over-voltage, and over-temperature, making it safe for everyday drivers without technical knowledge
- Universal 12V compatibility works on cars, motorcycles, RVs, boats, yachts, forklifts, and other 12V systems
- Weighs approximately 1kg and fits in a glove box, centre console, or boot bag

Installation Notes and Special Functions
No permanent installation is required. The GOOLOO A3 operates as a standalone plug-and-play device.
To jump start a vehicle, connect the clamps to the battery terminals with red to positive and black to negative, follow the LED safety prompts on the unit, and start the engine. The smart detection circuit identifies deeply discharged batteries before attempting a jump and prompts the user accordingly, preventing false starts and protecting the unit from damage.
To inflate a tyre, connect the inflation hose using the included nozzle adapters, set the target PSI value on the unit, and press start. The compressor cuts power automatically once the programmed pressure is reached.
The LED torch activates independently from the jump starter and compressor functions and requires no connection to a vehicle.
No professional installation is required, but users who are unfamiliar with battery terminal safety should read the included instruction manual before first use. Do not connect to wet terminals or operate the unit in standing water.
For storage, keep the unit charged to at least 50 percent capacity and recharge fully every six months if the device is not in regular use.
