Jump-start performance
You’ll appreciate how much starting power is available when you need it most, especially for larger engines and deeper discharges. The 4000A peak output and BOOST mode give you the ability to overcome low-voltage batteries more reliably than smaller jump packs.
4000A peak and BOOST mode
The 4000A peak specification means the GOOLOO A5 can handle substantial cranking current demands, making it suitable for full-size pickups and many diesel applications up to 10.0L. When you face a near-dead battery, the BOOST function helps stabilize low-voltage conditions to get the vehicle started fast.
Real-world jump tests and reliability
In typical testing scenarios, the A5 will restart most 12V vehicles repeatedly on a single charge depending on battery condition and temperature. You can expect many starts per charge in moderate conditions, and the unit is rated for operation from very cold to very hot environments so you’re less likely to be caught out by weather.
Air compressor performance
The integrated inflator is a standout feature if you want more than just a tiny tire pump; it’s built for heavy-duty tasks and rapid inflation. With a larger 25 mm motor and up to 160 PSI, it handles truck tires, SUV tires, passenger cars, and smaller inflatables efficiently.
160 PSI capacity and 25 mm motor
The bigger 25 mm motor provides more airflow than typical compact inflators that use smaller motors, which translates into faster real-world inflation times. You’ll notice the difference when inflating larger tires or topping off a spare in the rain or at the side of the road.
Inflation examples and timings
GOOLOO provides real-world timings: for example, inflating a 285/70 R17 pickup tire from 30 PSI to 36 PSI in about 2 minutes, or a 195/65 R15 sedan tire from 30 PSI to 36 PSI in roughly 30 seconds. These examples translate into meaningful time savings when you need to correct pressure quickly and continue driving.
Auto-stop, presets, and accessories
You can choose from five inflation modes and use five included nozzles for different tasks, and the pump will auto-stop once your preset pressure is reached. That feature removes guesswork and reduces the risk of over-inflation, which is especially handy when you’re inflating multiple tires or items at night.
Power bank and charging capabilities
The A5 doubles as a genuine 20,000mAh power bank so you’re not relying solely on inflated marketing numbers—it’s honestly rated for real usage. The integrated 45W USB-C cable (output-only) plus additional USB outputs make it practical for charging phones, tablets, and small laptops in a pinch.
45W USB-C output for devices
That 45W USB-C output gives you enough power for fast-charging many phones and tablets, and even some small laptops that accept 45W charging. The convenience of a built-in cable saves you digging through your bag for a separate lead when your phone is at 1% after a long drive.
Battery life and realistic numbers
GOOLOO states the unit supports up to 50 engine starts, 50 minutes of continuous inflation, multiple phone/tablet top-ups, and up to 99 hours of lighting depending on the mode. Those are realistic, conservative claims based on the rated 20,000mAh battery and make planning easy for weekend trips or emergency preparedness.
LED light and display
The LED system on the A5 is more than a basic flashlight; you’ll find several useful modes and a highly visible display that helps you monitor status while working outdoors. The display’s 2000-nit brightness keeps information readable in bright daylight, which is a practical usability advantage.
Sunlight-readable display and rotating status ring
The color LED screen includes a rotating status ring that shows inflation progress in real time, making it simple to see where you’re at without staring at numbers. The 2000-nit brightness ensures you won’t have to shade the screen with your hand in bright sun to check pressure or battery level.
Lighting modes and runtime
The unit includes multiple lighting modes and claims up to 99 hours of runtime depending on which mode you choose, making it useful for roadside repairs, campsite tasks, or emergency signaling. You’ll find the light helpful both for hands-free illumination and for signaling in low-visibility situations.
Build quality and portability
Size and materials matter when you plan to store the device in a trunk and use it under stress, and the A5 balances ruggedness with portability. The dimensions make it easy to tuck away in a bag or under a seat, while its exterior feels durable enough for realistic automotive use.
Size, weight, and handling
At about 8.98 × 5.55 × 2.40 inches, the A5 is compact compared to many combination units, but still large enough to house the inflator and battery. The form factor makes it a practical trunk staple for drivers who want a single device that handles multiple tasks without occupying much space.
In-box accessories and carrying bag
GOOLOO supplies a complete accessory kit including smart jumper cables, a USB-A to USB-C cable, a USB-C to USB-C cable, pump tubing, five nozzles, and a carrying bag. That full complement reduces the need to buy extras and gets you ready to use the unit right away.
Safety features
Safety is critical with jump starters and compressors, and the A5 includes multiple protections to keep you and your vehicle safe during use. Those protections reduce risk when you operate the unit under stressful or rushed conditions.
Smart jumper cables and protections
The smart jumper cable provides reverse polarity protection, short-circuit protection, and other safety measures to prevent damage to the vehicle’s electrical system or to the jump starter. The smart clamps and built-in electronics cut power in unsafe conditions so you can use the unit with greater confidence.
Operating temperature and durability
The device is rated to function from -4°F to 140°F, which covers most climates and use cases you’ll encounter on the road. The broad temperature tolerance means you’re less likely to lose capability in extreme weather, whether in a bitter winter morning or a hot desert afternoon.
How to use the GOOLOO A5: Jump-starting your car
Using this unit for a jump start is straightforward, and you’ll want to follow steps carefully to keep everything safe. Here’s a friendly step-by-step guide to get you moving quickly.
Step 1 — Prepare the vehicle and A5
Park both vehicles on level ground if using another vehicle, or position yourself safely on the roadside if using just the A5, and engage both parking brakes. Make sure the A5 is charged and the smart jumper cable is connected to the unit before you attach clamps to the battery.
Step 2 — Connect jumper clamps correctly
Attach the positive (red) clamp to the positive battery terminal, then attach the negative (black) clamp to a solid unpainted metal ground point on the engine block or chassis away from the battery. Double-check that clamps are secure and not touching each other or moving engine parts.
Step 3 — Engage BOOST if necessary and start
If the battery is deeply discharged, tap BOOST on the unit to enable low-voltage assistance and then attempt to start the vehicle. Once the engine starts, disconnect the clamps in reverse order, stow the cables, and allow the alternator to recharge the vehicle battery for 15–30 minutes or as appropriate.
How to use the GOOLOO A5: Inflating tires and items
The inflator is fast and has preset modes, but proper setup will save you time and reduce frustration. Follow these steps for consistent results.
Step 1 — Choose the correct nozzle and mode
Select the nozzle size that fits the item you’re inflating and set the target PSI on the unit using one of the preset modes or manual mode. Make sure the pump tube and nozzle are sealed properly on the valve stem to minimize leakage.
Step 2 — Monitor the rotation ring and auto-stop
Start the pump and watch the display ring for real-time inflation progress; the pump will auto-stop when the preset pressure is reached. If you need partial fills or a different pressure, cancel, adjust the preset, and resume inflation.
How to use the GOOLOO A5: Charging phones and devices
Using the A5 as a power bank is simple, but keep a few practical points in mind to optimize charging speed and battery life. The integrated cable makes charging a phone easier when you’re on the go.
