Which is better for jump-starting a car?

The Gooloo GT160. It has a 1200A peak current and jump-starts engines up to 7.0L gas or 5.5L diesel. The AstroAI has no jump-start function.

Which inflates a tire faster?

The Gooloo. Its 35L/min airflow is about double the AstroAI's 17L/min, and Gooloo says it fills a 205/55/R14 tire in about a minute.

Is the Gooloo worth the extra $20?

Yes if you want cordless use, a jump starter, or a power bank. If you only top up tires at home, the $19.99 AstroAI covers that for less.

Which lasts longer on one charge?

The Gooloo, with up to 45 minutes of cordless runtime. The AstroAI runs off the car socket and needs a cooldown after about 15 minutes.

Can the AstroAI inflate a completely flat tire?

Yes, but slowly. It is rated to 150 PSI and has auto shut-off, but its lower airflow means a full fill takes longer than on the Gooloo.

Do both have auto shut-off?

Yes. Both stop at your preset pressure. The Gooloo adds four preset modes (car, motorcycle, bike, ball) plus manual mode from 4 to 160 PSI.
