What’s in the box?
You’ll find a full accessory kit that gets you on the road quickly without hunting for add-ons. The A5 comes with smart jump cables, two types of USB cables, a pump tube plus five inflation nozzles to handle cars, bikes, balls, and small inflatables, and a carrying bag to keep everything neat.
Design and build quality
The A5 has a rugged, rectangular body sized for trunk storage, with textured surfaces and reinforced corners to survive being moved around. You’ll notice the build feels purposeful: ports are grouped logically, the integrated USB-C cable tucks into the side, and the compressor pump channels are neatly sealed to prevent accidental damage.
Jump starting performance
You can expect up to 4000A of peak current, which is enough to restart most 12V vehicles including all gasoline engines and diesels up to 10.0L. The included smart jumper cable protects against reverse polarity, short circuits, and overcurrent, so you can make the connection with confidence. For very low-voltage or near-dead batteries there’s a BOOST mode that supplies extra surge current to get a stubborn battery turning over.
Air compressor / tire inflator performance
The A5 uses a 25 mm high-efficiency motor that can reach 160 PSI. That translates into faster inflation compared with many portable inflators that use smaller motors. In practical terms, the manufacturer lists examples such as 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. You can choose between five inflation modes and the pump auto-stops when your preset pressure is reached so you don’t over-inflate.
Power bank and charging
The unit contains an honest, rated 20,000mAh battery, and GOOLOO emphasizes that this is an actual capacity rather than an inflated number. You’ll get multiple top-ups for phones and tablets, and the integrated 45W USB-C cable provides higher-power output for laptops and fast-charging phones (output-only cable). Expect the unit to support many small devices for a full weekend away and multiple vehicle starts before you need to recharge the A5 itself.
LED light and display
You’ll find a bright LED light with multiple modes for emergencies and roadside repairs. The 2026 model adds a sunlight-readable color LED display with a rotating status ring that shows inflation progress in real time. At up to 2000 nits of brightness the screen stays readable outdoors, which makes setting your target tire pressure and watching progress much easier when you’re dealing with bright daylight.
Usability and controls
Controls are straightforward: power on, select a function (jump, inflate, or charge), set the preset pressure for the inflator, and plug in. The smart jumper cable is keyed to prevent incorrect connections, and the inflator has an auto-stop feature that removes guesswork. The integrated USB-C output cable means one less cord to lose, although you’ll still use the included USB-A to USB-C or USB-C to USB-C cables for other devices.
Portability and storage
At roughly 9 × 5.5 × 2.4 inches, the A5 is compact enough to fit under a trunk organizer or in a hatchback storage compartment. The carrying bag keeps everything together, so you’ll be less likely to misplace the small nozzles and pump tube. While not the lightest device on the market, it strikes a good balance between capacity, power, and portability so you can comfortably keep it in your vehicle without it taking up precious space.
Battery capacity and real-world numbers
GOOLOO claims a real 20,000mAh battery and provides practical numbers to go with it: 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 real-world-oriented metrics that help you plan: if you use the unit mainly for short emergency starts and occasional phone charging, you’ll likely only need to recharge the A5 every few weeks or months depending on usage.
Temperature and reliability
The A5 is rated to operate between -4°F and 140°F, which covers most climates you’re likely to encounter. That operating window means the unit should perform at cold winter roadside jumps as well as hot summer days in direct sunlight. The design also resists normal knocks and bumps, which matters when it’s stored in a trunk with heavy gear.
Inflation modes and nozzle options
You can select from five inflation modes on the A5, letting you preset the target pressure for cars, trucks, motorcycles, bicycles, or small inflatables. The kit’s five nozzles cover a wide variety of valves: standard Schrader valves for cars and bikes, tapered nozzles for sports balls, and other connectors for inflatables and air mattresses. The preset auto-stop reduces the risk of over-inflation and helps you avoid manual checks with a gauge.
Integrated 45W USB-C cable and charging behavior
A notable convenience is the built-in 45W USB-C output cable, which is output-only and meant for charging devices not for data transfer. You’ll appreciate not having to carry a separate USB-C cable just to charge a laptop or phone in the car. For other device cables the box includes USB-A→USB-C and USB-C→USB-C, so you can charge older and newer devices using the same kit.
Display and user feedback
The color LED with a rotating status ring is a thoughtful touch that gives you instant visual feedback while the inflator is running. You’ll be able to glance at the unit and see whether inflation is progressing or done, even in bright sunlight thanks to the 2000-nit brightness. This is more user-friendly than a small two-line LCD and less fiddly than relying solely on audible beeps.
Safety features
Safety is built in with reverse-polarity protection, short circuit protection, overcurrent protection, and over-temperature protection for both the jump starter and the inflator. The smart jumper cable reduces the chance of user error, and the auto-stop inflator helps prevent over-inflation. You’ll still need to follow general safety practices — keep metal objects away from the clamps, connect correctly, and don’t operate the unit in extremely wet conditions.
Real-world test: jump starting a dead battery
When you’re facing a dead battery, the A5’s 4000A peak current comes into play. In tests like restarting a mid-size sedan after headlights, interior lights, and a short period of standby drained the battery, the A5 started the engine on the first try. If you encounter a battery that’s severely sulfated or otherwise damaged, the device can’t fix the battery — but it will get you running so you can drive to service.
Real-world test: inflating tires under load
The larger 25 mm motor shows up in the inflator’s performance. For heavier truck or SUV tires you’ll feel faster airflow and shorter inflation times compared to many compact inflators. The listed example — a 285/70 R17 pickup tire going from 30 to 36 PSI in about 2 minutes — reflects an ability to handle real world, heavier-volume tires where some smaller pumps struggle and overheat.
Real-world test: charging devices
With an actual 20,000mAh pack and a 45W USB-C output, you can charge phones, tablets, and some laptops without issue. You’ll find that modern phones charge quickly via the USB-C line and you can usually get a full phone charge plus a top-up for a tablet before the A5 needs recharging. If you plan to charge a power-hungry laptop for extended sessions, monitor the power draw because the integrated cable is output-only and designed primarily for on-the-go top-ups.
Comparison to similar products
Compared with single-function inflators or jump starters with lower amp ratings, the A5 gives you a lot of versatility. Some cheaper inflators will struggle with large truck tires and slower inflators often force you to run the pump for extended stretches, which can overheat smaller motors. Other combo units may claim larger battery capacities, but GOOLOO’s honest 20,000mAh rating makes it easier for you to predict real-world performance.

Who should buy the GOOLOO A5
You should consider the A5 if you want a single, reliable device to handle roadside emergencies and occasional maintenance. It’s a strong option for drivers of pickups, SUVs, and sedans who value the ability to inflate tires quickly and also need a dependable jump starter. If you regularly go off-road, take long road trips, or want a compact power bank for weekend gear, this unit will likely meet your needs.
Who might want something else
If you need a constant, heavy-duty inflator for professional tire shops or repeated commercial use, a dedicated full-size compressor is a better fit. If you want the absolute lightest unit for occasional phone charging and the rare jump start, there are smaller, cheaper options, but they won’t match the A5’s balanced combination of inflation power and jump-start capability.
Tips for use and maintenance
- Keep the unit charged: top it up every couple months if unused so you’ll have the necessary voltage when an emergency arises.
- Store the pump tube and nozzles in the carrying bag to avoid losing them.
- Before jump starting, double-check clamp polarity and ensure clamps are fully seated for the best connection.
- For multiple inflations in quick succession, allow the motor to cool between heavier uses to protect it from overheating.
- Clean the clamps and contacts occasionally to ensure good electrical connection and longer life.
Troubleshooting common issues
- If the unit won’t jump start: confirm clamps are connected correctly, check the A5 has enough charge, and try BOOST mode for very low battery voltages.
- If the inflator stalls or is very slow: ensure the nozzle is well-sealed on the valve; check for leaks; and if the motor gets hot, let it cool for a few minutes before continuing.
- If a device won’t charge: try a different cable from the included kit to rule out cable damage, and check the A5’s output status on the display.
Safety and best practices
You should always follow basic battery safety when using jump starters. Wear eye protection if you’re working close to the battery, remove metal jewelry that could accidentally short a clamp, and never allow the clamps to touch each other while connected to the battery. Use the auto-stop inflator feature to prevent over-inflation and set the correct tire pressure based on your vehicle’s placard or owner’s manual.
Warranty and customer support
GOOLOO backs the A5 with an 18-month warranty — longer than many competitors’ standard 12-month offers — which gives you additional peace of mind for a longer period. The full accessory kit in-box reduces the chance you’ll need separate purchases, and customer support channels are available should you need replacement accessories or troubleshooting help.
Value for money
Considering its combination of reliable jump starting power, fast inflation capability, a genuine 20,000mAh battery, and a useful integrated high-power USB-C output, the A5 represents strong value for what it offers. You’re getting four tools in one unit with user-friendly features like a bright display, auto-stop pump, and smart jumper cable — making the initial cost reasonable for the convenience and safety it provides.
