AstroAI T4 Truck Air Compressor with Auto Shutoff, Alligator Clips, LED Light for Off-Road, Pickup, SUV, RV (Up to 33 Inch Tires)

The best

It works great. I had to use my roadside service and they had one once I saw it. I came home and ordered one for myself.

Stop looking

Stop looking, this pump works great. Good quality. Good idea to connect to battery , pumps fast.

Reliable

I use this frequently and it has never given me any problem it definitely saves me a trip to the local tire shop to get air when the sensor comes on.

Way better than expected for the price

This pump has plenty of power. My tires were low because of the -19*F weather overnight. Took about 10 seconds to go from 30psi to 42psi. And it shut off when it got to the 42psi setting. The pump is more stout than it looks too!

Fast filling of RV tires.

Sturdy and fast. Didn’t expect no 120v plug but battery connector not a problem.

Perfect for work trucks

I have bought 2 of these for our work trucks & they work great!! The hose is super long which my drivers love & they pump up the tires quickly.

Tire Inflator

Awesome. Used it within 3 days of purchase. Works as advertised.

Great inflator. It pulls 64 amps inrush current. The compresor head gets to 200 degrees F.

Initial review: Very nice inflator. Fairly quiet, much faster than those cigarette lighter models.
Standard car cigarette lighter sockets (also called 12V auxiliary power outlets) are typically rated for a maximum of 10-15 amps.
This little powerhouse pulls 19 amps while running, which is the reason you can't plug it into the 12V socket.
It also pulls 64 amps inrush current, for about 10 milliseconds: the reason the inline slow-blow fuse holds up.
I ran 3 tests, it pulled, 61A, 63A, and 64A inrush current.

It does heat up, so be careful not to grab the compressor head, it gets over 200 F in under 1 minute.

If you are trying to use this without a car nearby, you need a 100 amp CCA 12 volt battery to connect it to.

Don't try powering this with a 12V power tool battery; the 64A inrush current I measured will cause voltage drop, shutdown, or damage, as these batteries lack current limiting and can't sustain such draws. Stick to car/truck batteries with the included clips for safe use.

High-draw devices like the AstroAI T4 (rated around 20-25 amps continuous, with inrush spikes) can pull far more current than typical power tool batteries provide: often 10-30 amps max continuous for 12V models, depending on size (e.g., 2-5Ah packs). Attempting this risks excessive voltage sag, overheating, BMS shutdown, or permanent battery damage from the inrush current overwhelming the cells.
