WOLFBOX MV24A 4000A Jump Starter with 160PSI Air Compressor, 12V Car Battery Booster, 88.8Wh Portable Jump Box (10L Gas/10L Diesel) with 65W Fast Charging, Tire Inflator, Jumper Cables, LED Light

This jump starter is a real beast! First of all, it effortlessly jump starts a car with a drained battery--many times over. Second, the compressor is fast and accurate. Simply connect the air hose and the correct attachment for the tire or tube. Then select the target air pressure. In my experience, the tires come up to pressure rapidly (faster than most portable electric compressors) and the unit shuts off when the pressure reaches the target PSI. I have double checked with an independent gage and found it to be accurate. (Exception: I don't think the pressure measures accurately with the needle to pump up a basketball. We tried it on a rubber ball and popped it.) The digital controls make it a breeze to operate--no pun intended. It's a little larger than some jump starters but more compact than a jump starter and a compressor separately. I bought one of these after leaving the accessory power on in my 2020 Honda CR-V and draining the battery. Fortunately, the business that I was parked at had a customer who had a jump starter. Not this model but it worked and I decided to never be without one again. So, I did my research and decided on the Wolfbox with the compressor. I also have one of those spare tires that needs 60 PSI. I popped a tire a year ago in a national park and found that the pressure in the spare was low. I babied it along home--all the while worrying because my TPMS had given up and shut off all of my automated features (cruise control, blind spot monitoring, etc.). Weird that they should all fail in solidarity, right? Finally, a shopping tip, buy it in combo with the 65W charger for $10 more or you will likely need to order the charger separately at a higher price. It's a USB C connection and my laptop charger is 65W--so, I got lucky. But I have been gifting them to my adult children for their birthdays and made the mistake of buying 4 of them without the chargers and paying $15 or $16 each for an alternate brand.

The is an amazing place of equipment, it charges well, the air compressor is powerful, very efficient , compact and easy to use. It ts very reliable and made of outstanding materials

I freaking love this. I use it mostly for blowing up my tires. And it's so much quieter than the Halo bolt air was. I wind up using this a ton, as someone always needs it. I haven't jumped a car yet but I expect it to Excel at that too. I'm such a believer that everyone should have theses in their car that I bought my daughter's Halo bolts as well. They will be getting these when theirs need replacement. Could not be happier with my purchase.

This thing is an absolute beast, I love it. I use it around the farm and today I used it to jumpstart a tractor, then fill (not exaggerating) 14 trailer/dually tires in preparation for harvest. It filled all the tires (many of which were quite low) and still had one bar of power! I’ll be ordering another so I can have one in the barn and one in my truck. Absolutely great product.

I bought this thing to throw in my car, in case I ever need to use it. I have pumped up 5-8 motorcycle/bike/scooter tires, and it was effortless. I jumped a buddy's car, as well, and it was also effortless. Keeps the charge very well. In my opinion, every car should have one of these in the trunk.

WOLFBOX 4000A Jump Starter MegaVolt 24 Air WOLFBOX Jump Starter with Air Compressor I just got it today and so can't speak of the ability to start a car, but I have used the air pump and charged my phones with it. Here is my feedback on that. First, the bad: 1) The USB-C to USB-C cable that comes with it is adequate for charging the WolfBox, but not for an Android phone. I bought the extra WolfBox 65amp charger and it charged the WolfBox just fine using the WolfBox supplied cable. Then when I plug that same cable into my Samsung S22 it warns me that I need to immediately unplug the cable from my phone. It says there may be liquid or debris in the port. I suspected that the cable is manufactured to cut corners and is missing some connections, and that turns out to be the case. USB-C cables can have up to 24 wires (PINS) plus a shield wire. Using a USB cable tester, my high-end Lenovo power USB-C to USB-C cable has PINROW A 1/2/3/4/5/8/9/10/11/12 and PINROW B 1/2/3/4/5/6/7/8/9/10/11/12, plus Shield. The only thing missing are PINROW A6 and A7. The WolfBox USB-C to USB-C cable is missing PINROW A 2/3/6/7/10/11 and PINROW B 2/3/8/10/11. I have never seen a USB-C cable missing so may PINROW connections. My phone hates it, and why would I want to keep it in the WolfBox package if it can't even be used to charge a phone? I will substitute my Lenovo cable, which both charges the WolfBox and lets the WolfBox charge my phone. Shame on you WolfBox for cutting corners on that cable! 2) There is an additional power-out port on the device that the documentation doesn't explain, other than to say it's there. It's labeled 15v/10A and nowhere does it say what size of plug you might buy to take advantage of it. 3) It could use some strap or carrying handle. It's relatively heavy and made of slick plastic. I would not want to have to use it in an emergency in the snow and mud. Now, the good: 4) It pumped up the tires on my car nicely. I like how you can set it to the PSI you want and then it stops automatically. The air hose port got very hot just putting a few PSI into my little car tires, so I imagine that a big truck would bring it to near meltdown. 5) The zippered case it comes in is nice, and there's enough room in there for the 65w extra charger I bought so I can charge the thing.

Excellent for work truck emergency kit. I used it on my toyota tacoma and 4 runner. easy to use & plenty of power to fill the tires. Great choice.

This was a great investment, really happy that I purchased It was able to jumpstart my Jeep with a completely dead battery in less than a minute.

Die Wolfbox Starthilfe macht auf Anhieb einen sehr hochwertigen Eindruck. Verarbeitung und Haptik sind top, die Bedienung ist einfach und nach wenigen Minuten hat man alle Funktionen verstanden. Besonders praktisch finde ich den integrierten Kompressor. Es stehen fünf voreingestellte Modi zur Verfügung (Auto, Motorrad, Fahrrad, Ball und ein frei einstellbarer Custom-Modus), sodass der passende Druck schnell gewählt ist. Bis zu 10 bar sind im Fahrradmodus möglich. Ich habe bereits Bälle aufgepumpt, den Luftdruck am Auto und Fahrrad kontrolliert sowie eine Schubkarre befüllt – alles hat zuverlässig funktioniert. Zum Lieferumfang gehören außerdem verschiedene Ventiladapter, unter anderem für Bälle und französische (Presta-)Ventile. Die Anleitung könnte an dieser Stelle etwas ausführlicher sein, denn zunächst war mir nicht klar, wie die Adapter verwendet werden. Sie werden einfach in den fest am Luftschlauch verbauten Autoventilanschluss eingesetzt und anschließend durch das Verriegeln des Ventils fixiert. Sitzt der Adapter einmal richtig, funktioniert das Ganze problemlos. Auch der Batteriestarter überzeugt. Die LED-Anzeige ist gut ablesbar und der Verpolungsschutz sorgt für zusätzliche Sicherheit. Zum Glück musste ich ihn noch nicht zum Starten eines Fahrzeugs einsetzen, die Funktionen machen aber einen durchdachten Eindruck. Zusätzlich gibt es ein integriertes LED-Licht mit drei Modi (Dauerlicht sowie Blinkfunktionen), was bei einer Panne oder Arbeiten im Dunkeln sehr praktisch ist. Über USB-A und USB-C lassen sich außerdem Smartphone oder andere Geräte laden – ebenfalls ein nützliches Extra. Zum Aufladen des Geräts sollte man allerdings ein Netzteil mit mindestens 65 Watt verwenden, damit der Akku in angemessener Zeit wieder vollständig geladen wird. Besonders geärgert habe ich mich, dass ich das Gerät vor Kurzem noch nicht hatte. Durch eine Schraube im Reifen hatte ich schleichenden Luftverlust und musste ständig nach der nächsten Tankstelle suchen. Mit der Wolfbox hätte ich den Reifen einfach unterwegs immer wieder aufpumpen und problemlos bis nach Hause fahren können. Genau für solche Situationen ist das Gerät Gold wert. Abgerundet wird das Ganze durch eine stabile und kompakte Aufbewahrungsbox, in der alles ordentlich verstaut ist. Das Gerät passt problemlos ins Handschuhfach und ist damit jederzeit griffbereit. Für mich eine sinnvolle Anschaffung, die hoffentlich nur selten zum Einsatz kommt – im Ernstfall aber jede Menge Zeit und Nerven sparen kann.

Great unit, lots of power, starts my 6BT Cummins diesel, and 300 horse outboard. Good compressor, fast shipping.

An excellent jump starter and Air compressor with effective light.

Cet appareil se charge très vite. J'ai eu l'occasion de regonfler deux pneus de la voiture. Il m'a suffit d'indiquer la pression à atteindre sur la première ligne. Vous raccorder le gonfleur. Vous verrez immédiatement la pression restante. Vous mettez en route le gonfleur qui s'arrêtera des que la pressiondelandée est atteinte, et tout cela sans trop de bruit et très rapidement. En ce qui concerne le démarrage électrique, je ne l'ai pas encore test. Personnellement, le le recommande.
