What Is It?

The WOLFBOX 4000A Jump Starter with 160 PSI Air Compressor is a 12V portable lithium battery booster combined with a 160 PSI tire inflator — eliminating the need for a separate air compressor in your trunk. This is the best-selling unit in the WOLFBOX line, holding a 4.6-star Amazon rating and ranking among the best-sellers in Amazon's Jump Starters subcategory.

After comparing it against 8 competing 2-in-1 jump starters in the $100–$200 range, this stands out for its 4000A peak output (handling 10L gas/diesel engines), 65W USB-C fast charging, IP64 dust/water rating, and a 24-month limited warranty backed by 24/7 customer service — making it the most-purchased mid-tier choice for drivers who want jump-start + tire inflation in one device.

Replaced 3 trunk items with one box

This multifunction jump starter took the place of multiple previous items in my car's trunk, but most importantly the 12v compressor I used to carry all the time. Out of the box, it had a half charge and via a USB-C source, I was able to top it up in less than an hour.

Inflated 4 tires in under 4 minutes total

When the cold hit the northeast, 4 of my tires were down by 5 PSI and I could feel it in the steering. This little Wolfbox inflated all 4 tires in under 1 minute each. Much better than waiting in line at the local market for the air compressor.

Air hose gets hot during long fills

The connector between the device and the air hose does get hot when filling for a while but I can't take anything away as it is clear that will happen from the warnings and document. For passenger-car tires it's no issue.

Frequently Asked Questions

Common questions from shoppers considering this product:

Q:How fast can the inflator pump up a tire?
A:Per WOLFBOX's specs (verified by reviewers): 2 min 30 sec to inflate a 315/70 R17 pickup truck tire from 30→36 PSI; 1 min 20 sec for a 275/70 R17 SUV tire; 40 seconds for a 195/65 R15 sedan tire from 29→36 PSI.
Q:Does the air hose get hot during use?
A:Yes — multiple reviewers note the air-hose connector heats up during longer fills (e.g., truck tires from low pressure). WOLFBOX flags this in the documentation as expected behavior. For passenger-car tires this isn't an issue; for truck tires plan for a brief cool-down between fills.
Q:Does it include a wall charger?
A:No — this 2-in-1 model ships with the unit, jumper clamps, USB-C cable, and case, but does NOT include a wall plug charger. WOLFBOX sells a compatible 65W charger separately. The bare 4000A model (rank 2 in this list) does include the wall charger.
Q:Is the 4000A overkill for a 4-cylinder car?
A:Yes — 4000A is rated for engines up to 10L gas or diesel. A 4-cylinder car (typically 1.6–2.5L) only needs ~1,500A peak. Pick this if you have a mixed garage (truck + car), tow with a 6+ cylinder vehicle, or want headroom for cold-weather starts.

Bottom Line

The WOLFBOX 4000A Jump Starter with 160 PSI Air Compressor is the most-purchased unit in the WOLFBOX line for good reason. Combining 4000A jump-start power with a 160 PSI tire inflator eliminates two trunk items at once. With strong verified-buyer volume, a 4.6-star Amazon rating, and consistent best-seller status in Amazon's Jump Starters subcategory, it's the volume-pick mid-tier choice — at $125.99, just $6 over the bare unit but adding a $40+ tire-inflator's worth of utility.
