AstroAI S8 Air 3000A Jump Starter & 150PSI Air Compressor Inflator
Product description
High-performance jump starting and multi-function utility: The S8 Air packs a 3000A peak lithium battery capable of jump-starting 12V systems and is rated to handle up to 9L gasoline and 6.5L diesel engines. It claims multiple jump starts per full charge and operates across a wide temperature range from -4°F to 140°F.
Integrated 150PSI air compressor: The unit includes a built-in inflator with a maximum pressure of 150PSI and selectable units (PSI, KPA, BAR). The pump delivers up to 25L/min for rapid inflation and has five preset modes for common inflation jobs. The compressor will automatically stop once the preset pressure is reached, and the hose and fittings can be stored with the unit.
Clear 2.4" display and user feedback: A sizable 2.4-inch digital display shows battery level, operating status, error codes, and live pressure readouts during inflation. The screen is designed to be readable in bright conditions, making it easier to monitor pressure and other indicators in real time.
Safety features and construction: The housing is molded from durable ABS to resist rough handling. The device incorporates ten electronic protections to prevent incorrect operation and meets national UL and FCC certification standards. A widened honeycomb vent design reduces internal temperature by roughly 30% to help cool the unit during use.
Compact organization and accessories: The pack stores its power cord and accessories internally so parts are not easily misplaced. Typical included items are the jumper clamps/cable, the inflation hose, USB output ports for charging devices, and adapter fittings for different inflatables. The device also provides three lighting modes—steady flashlight, SOS, and strobe.
Use and care guidance: Allow cooling time for the inflator hose after extended use as it gets hot during operation. To preserve battery longevity, fully charge before first use, operate within the specified temperature range, and recharge every 2–3 months during long storage. If inflation readings appear abnormally high, disconnect and briefly run the compressor without contact to clear blockages. For troubleshooting or warranty service, contact the manufacturer’s technical support.

Small but mighty
It works as it should. Has helped me out several times and I use it regularly. For its size it performs amazingly.

Great for tires and more
I mainly bought it for inflating tires and it exceeded expectations. Took a worst tire from 38 to 45 PSI in under two minutes. The display reads pressure and it stops automatically at the set value. During an outage I used the light and charged my phone. Haven’t needed the jump feature yet.

Valuable peace of mind
I’ve had it almost a year and it holds charge well. I haven’t needed to jump my car yet, but having the compressor and jump option is reassuring. Overall quality is solid and compact.

Worked exactly when needed
When my Land Rover’s battery died due to a faulty blower, this jumper started it without issue. Lightweight, easy to use, and surprisingly powerful—definitely worth keeping in the car.

Top pick for a car kit
If you don’t carry one of these you’re missing an essential item for your vehicle.

Essential for a family van
This combo is one of those emergency items you only realize you needed after the fact. It’s compact but powerful for both jump-starting and inflating tires. Our van’s battery often drains with all the devices and screens running, and this has let us restart without waiting for assistance. The inflator is handy for quick driveway checks and filling on the road. So far it has performed without any downsides.

Fast inflator, solid construction
The inflator is quick and reliable for both emergencies and routine maintenance. I haven’t needed to try the jump function, but the build feels robust and dependable. It’s a sizeable unit but that gives confidence in its capabilities.

Consumer on the budget 5/5
Every driver should own one
Fantastic purchase—compressor works great but needs a 10–15 minute cooldown after heavy use. Jumped an older small-block engine without trouble, and the light and charging kept my phone and handheld devices running during an outage. Gives real peace of mind. The battery indicator isn’t numeric, but I learned how it behaves.

Handy all-purpose emergency tool
Well-made product that matches the description. Used it during emergencies and it performed correctly.

MEL 4/5
E5 error rendered it useless
After many successful uses the unit threw an E5 error and became unresponsive except for the light. It would still take a charge but no longer worked for jump-starting or inflating. I suspect extended cranking may have triggered the fault. Online fixes didn’t help and warranty replacement seems uncertain.

Good value and useful accessories
Looks solid so far. Inflated my bike tire with included fittings and it was convenient. The unit charged my Android phone but would not recognize my iPhone. Haven’t had to use the jump starter yet.
