AstroAI S8 Air 3000A Jump Starter with Air Compressor, 12V Jump Box

Worked very well. The battery on my Landrover discovery drained due to a faulty fan blower module that ran for too long. Was able to jump start dead battery with this jumper pack. Very easy to use & lightweight, but powerful. Well worth it to have in your vehicle!

Planning a road trip. Got this as a little insurance. The features should fit any problem that could come up. Air pump, charger, jump starter, light. Compact and versatile.

This thing works great! I love it so much I got my wife the same model in a different color. We use them OFTEN for airing tires and have used them many times for jumping car batteries. Its a pure lifesaver when you're away from civilization..or just don't want to hassle with traditional avenues of addressing flats/dead batteries. The phone charging works great too.

Great little thing. Used it to jump a dead battery and worked quick. Also filled two tires with air. The battery goes pretty quick when using the tire psi function, which is why 4 stars. Im sure u would have to have charging capabilities close after adding air to tires. Yes would buy again.

Works perfectly and fast easy to use

Set psi and let it work,may take a few minutes but I don't mind! Haven't tried jumping off battery yet but the other one I had was weaker (2000A) but jumped car off fine. Happy with it so far 👍

I purchased this jump starter in March 2025. I kept it fully charged and stored it in my trunk for emergencies. Yesterday, I finally needed it to start a car that I hadn’t turned on for two months during the winter, and it worked perfectly. Impressively, the unit still showed 100% battery life even after sitting unused for such a long time. I haven’t tested the tire inflation feature yet, but I plan to try it soon. The design is simple, compact, and easy to store. Most importantly, it delivered plenty of power when I needed it. I'm very satisfied with this purchase.

I fully charged this unit when I received it (14 days ago), and it was on the way home last night that my car alerted for low tire pressure. I used the AstroAI S8 for the first time today to bring 8 tires up to their cold PSI recommendation. I found it very easy to attach and detach the hose/connector to all eight auto tires, with only a split second of any air loss. All eight tires needed the same setting (32 PSI cold), and I didn't have to keep adjusting the unit. I would say that the typical tire needed to increase about 8 PSI, and I timed one in my head at just under a minute to inflate to the proper level. I held the unit in hand to keep it off the wet concrete, and it never got warm enough to make me think it might get too hot. As for the battery, it was still at least 50% when I plugged it back in to recharge. Keep in mind that the unit sat 14 days, filled eight tires at about 8 PSI each, and that took it down to the 50-60% range. I've not yet needed to use it for a jump start, but I've gained some confidence based on other reviews and the ease of use for auto tire inflating.
