FlyAuto HH604 2000A Jump Starter with 150 PSI Inflator

The FlyAuto HH604 combines a lead-acid car jump starter with a tire inflator, USB charging, a 12V DC output and an LED light. The listing gives different engine-size limits in the title and feature details, so buyers should confirm compatibility before relying on it for a specific vehicle.

At a glance

Combines jump-starting and tire inflation in one unit, with USB charging, a 12V DC port and an LED light.
The listing claims 2000A peak current and a 150 PSI maximum inflator pressure.
The feature description claims it can inflate a tire from 0 to 40 PSI in 2 minutes. This is a listing claim, not an independently verified result.

What to know before buying

Listing details to confirm

The listing is inconsistent about engine compatibility: its title says up to 10.0L gas or 8.0L diesel, while a feature says 6.0L gas or 5.0L diesel. The advertised 2000A output, 150 PSI maximum and inflation-time claim are not independent performance measurements. Confirm the applicable engine limits and suitability for your vehicle before purchase.
