WOLFBOX 4000A Jump Starter with 160PSI Air Compressor, 12V Car Battery Booster, 65W Fast Charge, 24000mAh Portable Tire Inflator, LED Display for 10L Gas & 10L Diesel Engines,… by WOLFBOX

This thing’s a total game changer. The first time I used it, my truck battery was completely dead—and the WOLFBOX fired it right up like nothing happened. A week later, I used it to help my neighbor, same story. The air compressor’s no slouch either—it filled my tires fast and even handled my bike with no problem.

What I really like is how easy it is to use. The screen’s clear, the light’s bright, and it doesn’t feel cheap. Plus, it charges my phone super quick. It’s one of those things you hope you don’t need often, but when you do, you’re damn glad you have it. Five solid stars from me.

Works great!

So far so good. Bought this baddie to figure out where a parasitic drain was coming from, ive had it for about two weeks. It has a battery tester, which was a pleasant surprise since i just had a hunch that the car battery was not bad. so ive used it for the jump at very least 3x a day (it gets embarrassing to do on a new car trust me) but id have to jump the car every time I started it until i was able to fully charge the 12v via driving+alternator. I only charged the car battery with this box for about 45 maximum max but I also did not check my battery to see where it was at before hand witha voltmeter because i knew it was completely drained. The wolfbox effectively repowered the entire car, all accessories ect after 45 minutes. I still had more than half the power left in the wolfbox, even after using the boost button a few times. Only charged the wolfbox when i bought it, and once more at the end of the week after jumping my car approximately 9x. I fully charged it again, carried me another week and only used half its power once again.
its so small, easy to use and the manual is small but easy to understand with spanish and english directions.
The 2 things i can shamelessly complain about are: length of cable lines (i have to rest the box by wiper blades when id like to be seated in my driverseat looking at stats) and the thickness of the clamps themselves… i have a hard time clamping the ground port (black) on my (car) battery because that part of the port is slightly under the lip of the dash, and the other is close against the battery box. Ill take a photo when i get some daylight or a video if its too difficult to make out via photo.
Overall, saved me from having to buy another battery (230$) and murdering that one too- (i didnt know the drain was parasitic right away) the time and dignity of being able to diagnose and fix my own issue without the hassle of anyone else trying to blow smoke up my tailpipe (priceless, truly) also caught this baddie on sale. Kind of excited for the weather to change so i can add some air to my tires and not have to wait in a free air line 🙃 but I digress.
Measure the clearance you have to clamp the ports and make sure you have (car) battery access first, note: before I bought this box, i asked someone with a 2025 explorer to give me a jump; his battery was within two compartments and the second was under the dash…there was absolutely no clamping access. Just a heads up for newer car people who are dealing with battery beef and are trying to avoid the dealership. ✌🏽

What a fantastic must have. This portable jump starter is a great addition to ANY car. At my trade, our shop has multiple cars. One of the vehicles had a dead battery and wanted to test this wolfbox jumper. And it worked flawlessly. You should use the boost mode for a better chance of starting the car when the battery is completely drained. The tire inflator is very helpful too. Filled up my tires and it automatically stops where it should. A bit expensive but worth the investment. Saving a lot more than calling a tow or having no service with a dead battery.

Pros:
jump starts almost any vehicle

Jumper cables are thick and durable

Has a boost mode on the jumper

Tells you if you have the jumper cables connected correctly.

Tire inflator is easy to use and can choose to fill other things like soccer balls, motorcycles, etc.

rechargeable with USB-C.

Comes with a hard case

Comes with usb c to usb c cord

Cons:

Does not come with the power brick.

Tire inflator is a bit loud, but not really a big deal.

Not a big deal also, but I wish there was two zippers.

Expensive.

Overall this is a fantastic device that can save you from being stranded.

Had a flat tire and this pumped it up in only a few minutes and allowed me to drive the car home. Absolute life saver and really good quality.
