The Gooloo A3 is a good fit for drivers who want jump starting and tire top-ups in one emergency kit. Choose it when both jobs matter, your vehicle falls within its engine limits, and you'll keep the unit charged.
Its main benefit is having a pump, clamps and emergency power together. If you already carry a reliable inflator, a separate jump starter may suit you better.
Our portable jump starter buying guide explains the wider choices if you're still deciding which type of kit to carry.
Who should buy the Gooloo A3?
The A3 suits daily drivers who want backup for a weak battery and a low tire without packing 2 separate powered tools. It's especially useful when you also need a pump for bikes or sports balls.
You still need to maintain the kit between emergencies. A combined tool only saves trouble if its battery is charged and its hose, clamps and nozzles are together.
When the Gooloo A3 makes sense
Choose the A3 if your main inflation job is an occasional pressure top-up and you want starting help available in the same bag. Its SUV, car, bike, ball and custom modes let you set up different jobs.
Those modes simplify selection, but you must enter the correct pressure for the item. A preset category doesn't know your vehicle's tire placard or your bicycle tire's requirements.
Who should skip it?
Skip the A3 if you need a different vehicle voltage, your engine exceeds its supported range, or you want a pump for repeated, lengthy inflation jobs. Those needs should guide the choice before extra features.
Drivers who already have a separate compressor should compare jump-only options in our best jump starter guide. Carrying another pump adds less value when that job is already covered.
What comes with the A3, and where will it fit?
The A3 includes the clamps, hose and nozzles needed to assemble its roadside kit. The box also contains a USB-A to USB-C cable, carrying bag and manual.
Gooloo A3: Best for everyday roadside backup
- 3,000A peak output
- 150 PSI inflator
- 12,000mAh battery
- LED flashlight
A combined emergency kit for drivers who want battery-starting help and occasional tire top-ups. Preset inflation, a pressure display and included nozzles also cover bikes and balls.
Pros
- BOOST mode for very low battery voltage
- Auto-stop inflation and digital pressure display
- Includes 5 nozzles and a carrying bag
- GOOLOO provides an 18-month warranty
Cons
- Shares battery power between starting, inflation and USB charging
- Charging temperature range is narrower than its operating range
The unit measures 4.96 x 5.87 x 2.3 in. Check the space for the complete bag rather than measuring only the main body.
Keep the clamps and air hose with the unit, with nothing heavy pressing on them. Store the small nozzles together so a missing adapter doesn't prevent you from using the pump.
The supplied charging cable isn't a wall adapter. Work out how you'll recharge the unit at home before leaving it in the car.
Will the A3 suit your engine and battery?
GOOLOO rates the A3's 3,000A peak output for 12V engines up to 9.0L gas or 6.5L diesel. Confirm both voltage and engine size before you buy.
Peak amps describe a brief output figure, not continuous charging power. They also don't explain every difference between jump starters with the same number on the box.
A cold engine, a deeply discharged battery and poor clamp contact can all make starting harder. Our guide to how many amps you need for a jump starter explains how to choose around your vehicle.
The A3 includes short-circuit, reverse-connection, overcurrent, overheating and overcharge protection among its 10 protective features. Correct connections still matter, so learn the vehicle's designated jump points before an emergency.
BOOST is for extremely low battery voltage, using GOOLOO's specified procedure. Don't treat it as the next automatic step whenever a normal attempt fails.
A jump starter supplies a short burst to help crank the engine. It doesn't restore a worn-out battery, repair an alternator or solve a fuel or starter-motor fault.
If your real need is recovering and maintaining a discharged battery at home, read jump starter vs battery charger before choosing equipment.
How useful is the A3's tire inflator?
The A3's pump is useful for bringing low tires back to their correct pressure and handling smaller inflation jobs. It has a 150 PSI maximum pressure, 35L/min airflow and automatic shut-off at your preset.
Maximum pressure isn't the pressure you should put in a car tire. Use the vehicle placard, usually found around the driver's door opening, or the owner's manual.
Check car tires when cold, before driving has warmed them. The maximum printed on the tire sidewall isn't the vehicle's recommended target.
GOOLOO says the A3 can raise a Tesla Model 3/Y tire from 30 PSI to 36 PSI in 1 minute. That's a specific top-up example, so don't use it to plan how long a fully flat or larger tire will take.
The display supports PSI, BAR and KPA. Confirm the selected unit before entering a target, since the same number means very different pressures in each unit.
Automatic shut-off saves you from repeatedly switching the pump off to check progress. Stay with the unit, watch for errors and check the finished pressure with a separate gauge when possible.
A pump can't repair a puncture, damaged sidewall or leaking valve. A tire that repeatedly loses pressure needs inspection, even if you can keep adding air.

Which alternative should you choose instead?
Choose an alternative when pickup tire top-ups, a larger status screen or broader engine support matters more than the A3's overall fit. Each option below has a clear reason to consider it.
| Product | Peak output | Inflator | Brand-rated engine support |
|---|---|---|---|
| Gooloo A3 | 3,000A | 150 PSI, 35L/min | Up to 9.0L gas, 6.5L diesel |
| Wolfbox MV16A | 3,000A | 160 PSI, 45L/min | Up to 8L gas, 6L diesel |
| AstroAI S8 Air | 3,000A | 150 PSI, 25L/min | Up to 9L gas, 6.5L diesel |
| Gooloo A5 | 4,000A | 160 PSI | All gas, up to 10.0L diesel |
Wolfbox MV16A: for pickup tire top-ups
Choose the Wolfbox if tire inflation and quick recharging drive your decision. Its airflow figure is higher than the A3's, and WOLFBOX describes inflation support for pickup tires and smaller vehicle tires.
It supports 65W USB-C charging, with WOLFBOX claiming a full recharge in as little as 1.5 hours. A charging adapter isn't included, so account for a suitable power source.
Skip it if carrying weight matters: it weighs 5.3 lb. Also check its engine limits carefully, since they are lower than the A3's despite matching peak-output figures.
AstroAI S8 Air: for a clear view of pressure
Choose the AstroAI if you want preset and current pressure visible together on a 2.4-inch screen. Battery level, operating status and error codes are also shown there.
At 2.4 lb, it's worth considering if you regularly move the kit between vehicles. Its accessory storage also helps keep the parts with the main unit.
Skip it for repeated long inflation sessions. AstroAI requires at least a 10-minute rest after 10 minutes of continuous pumping, and says to let the air tube cool before removing it.
Gooloo A5: for vehicles beyond the A3's range
Choose the A5 when your engine needs broader brand-rated support than the A3 offers. Confirm the exact vehicle requirements rather than buying it simply for the higher peak number.
It has a 20,000mAh battery and a built-in 45W USB-C output cable for devices. That built-in cable doesn't recharge the jump starter.
Skip it if the A3 already covers your vehicle and compact storage is your priority. The A5 measures 8.98 x 5.55 x 2.40 in and weighs 3.2 lb.
How should you set up the A3 before a trip?
Charge it fully, read both manuals and locate your vehicle's jump points before packing the A3. Learning the connections in daylight is easier than working them out beside a stalled car.
Use this first-use checklist:
- Confirm the vehicle is compatible and find its jump-start instructions.
- Charge the A3, then check its battery indicator.
- Inspect the clamps, cables, hose and connectors for damage.
- Find the vehicle's tire-pressure target and select the matching unit on the pump.
- Pack the kit somewhere accessible without unpacking the whole trunk.
Don't make your first attempt at understanding the controls during an emergency. Read the BOOST instructions separately, since low-voltage starting calls for extra attention to the procedure.
Our guide on how to use a portable jump starter explains the basic process. Follow the A3 and vehicle manuals for the exact connection order, attempt limits and waiting periods.
For inflation, connect the hose securely without forcing threads or bending the valve stem. Refit the valve cap and allow warm pump parts to cool before packing them away.
How should you charge and store it?
Keep the A3 charged on a schedule and after use, rather than waiting for a low-battery warning during an emergency. Its 12,000mAh battery supplies the starter, pump, USB charging and light.
Using it as a phone power bank draws from the same reserve you may need for the car. After a long inflation session or device charge, check the battery level and recharge as directed.
GOOLOO calls for a full charge before first use and recharging at least every 3 months during long storage. A calendar reminder makes that maintenance easier to remember.
The operating and storage range is -4°F to 140°F, while charging is limited to 14°F to 113°F. Let a very cold or hot unit return to a suitable charging temperature first.
Avoid prolonged heat, moisture and direct sunlight. An operating limit isn't a reason to leave the unit exposed on a hot dashboard.
After use, let the kit cool, wipe away dirt and check for damaged parts before storing it. Our guide to charging a jump starter covers the basic charging routine.
Which mistakes should you avoid?
The main mistakes are choosing by peak amps alone, entering the wrong tire pressure and forgetting recharge time. Preventing those errors matters more than using every extra feature.
- Confusing pressure with pump speed: A higher maximum PSI doesn't tell you how quickly a pump will top up your particular tire.
- Expecting a full battery charge: Getting the engine running doesn't mean the vehicle battery has recovered or will start again later.
- Repeatedly cranking without checking: Follow the allowed attempt length and cooling intervals instead of making back-to-back attempts.
- Ignoring a warning: Check the manual when the unit signals an error rather than trying to force a start.
- Relying on auto-stop alone: Enter the correct target and stay nearby while the pump runs.
- Leaving the kit depleted: Recharge after use and check it before a long trip.
Don't jump a battery that appears damaged, swollen, leaking or frozen. Follow the vehicle manual and seek help when the battery's condition is uncertain.
Should you choose the Gooloo A3?
Choose the Gooloo A3 for everyday roadside backup when your vehicle fits its engine limits and you want both starting help and tire top-ups. Make charging and accessory checks part of your car-care routine.
Pick the Wolfbox for pickup tire top-ups and fast charging, the AstroAI for its pressure-and-status display, or the A5 when your engine falls beyond the A3's supported range.
If you already own a good inflator, compare the size and convenience of a jump-only unit before adding another combined kit. For help choosing between the broader brand ranges, read NOCO vs GOOLOO.

Frequently asked questions
Can the Gooloo A3 inflate car tires?
Yes, the Gooloo A3 can top up car tires using its built-in pump and preset shut-off. Set the pressure from your vehicle's tire placard, with the tires cold, rather than using the tire sidewall maximum.
Stay nearby during inflation and check the finished pressure before driving.
What engines can the Gooloo A3 jump start?
GOOLOO rates the A3 for 12V vehicles with engines up to 9.0L gas or 6.5L diesel. Confirm your vehicle's voltage and engine size before choosing it.
A jump starter helps a weak battery crank an engine, but it won't repair a failed battery or another starting-system fault.
Does the Gooloo A3 have a BOOST mode?
Yes, the A3 has a BOOST button for extremely low battery voltage. Use it only after reading the manual's procedure and checking that the vehicle and clamp connections are correct.
Don't press BOOST simply because the engine hasn't started; first check the unit's indicators and instructions.
How should you store and charge the Gooloo A3?
Fully charge the A3 before first use and recharge it at least every 3 months during long storage. GOOLOO specifies use and storage from -4°F to 140°F, with charging from 14°F to 113°F.
Keep it dry and avoid prolonged heat or direct sunlight.
