WOLFBOX 4000A Jump Starter with 160PSI Air Compressor, 12V Car Battery Booster, 65W Fast Charge, 88.8Wh Portable Tire Inflator, LED Display for 10L Gas & 10L Diesel Engines, LED Light, Jumper Cables

Excellent product. When the real cold hit the northeast, the temperature dropped significantly. A 4 of my tires we down by 5 PSI and I could feel it in the steering. This little Wolfbox inflated all 4 tires in under 1 minute each!. This was much better than waiting in line at the local market for use of the air compressor. The design is intuitive and the screen is bright easy to read. the face of the box has large bold numbers and figures that make it easy to read. I did this in direct sunlight and it was still easy to read. The box came with half a charge and was fully charged within 2 hours. I highly recommend this product to be included in your vehicle for "just in case" situations.

Have had this for about a year. Let me tell you this is great. Have had to use twice for jump start. Once for myself and once for a nice lady with young kids stranded whose battery died. Both times this fired up the vehicle no problem. Now the other part the air pump. This has come in handy a few times. Before soccer practice for my girls to inflate soccer balls, a few times for bicycle tires, and even once for the baby stroller. Also the truck tires? No problem this sucker inflated them quick and easy. Saves a lot of time and money from air pumps at the service station. Love this. It’s a must have in the back of your vehicle. It gets used more the you would think. I didn’t think I would get as much use out of it over the course of a year. I actually bought a second one for my wife’s car. Pick this up if you are thinking about it. More than enough power and great battery life.

Really Good. it will completely jump start a 4.8L diesel engine with dead batteries. it lasted me around 4-6 jump starts with some other usage. Air compressor is great for what it is honestly really impressed and really compact for storing. i would strongly recommend it especially if you get it at a discount.

A quick summary is that this little unit holds a lot of power/features and is much better than my older lead-acid style jump starter/inflator device. I purchased this Wolfbox portable jump starter/air compressor to replace and older unit I previously kept in my vehicle. Although the old unit does still work, it is massive/bulky, taking up a lot of floor space in the back seat (it is the big yellow CAT unit in the photos/videos). And what a difference it is, sitting at less than half the size even in the carrying case. Apparently the Lithium-ion batteries in the Wolfbox are the way to go these days compared to the AGM lead-acid battery in my old unit. The Wolfbox unit comes with the jump starter/inflator, jumper cables, inflator hose, a few valve attachments, and a USB-C charging cable all packed within a nice carrying case. (and also a manual). Great presentation overall, and it feels sturdy/premium. The only note I can think of for Wolfbox to improve here would be to add a piece of foam in the center of the case to act as a divider/protection. This would keep the jumper cables/other contents stored in the pouch from touching/scratching the jump starter unit stored in the other half. Not a huge issue by any means, and I rectified this by cutting out my own piece of thin foam (you can see it in the pics). It looks so nice I would hate to see it scratched up over time. I charged it as-directed out-of-the-box, and it took less than 30 minutes to top it off. Reading in the manual, it says it would take 1.5-2hrs time for a full charge. My old unit recommended charging for 24 hours, so a big improvement there as well. Given this time of year, the cold temperatures have come in and caused all of my tires to lose some air pressure, setting off the dashboard warnings. So I thought this would be a perfect opportunity to compare the air compressor feature vs my old one since all tires needed to be filled 6-8psi. The short story is that the Wolfbox wins out again. I had two tires that both showed they were 6psi low exactly, so I set my old unit on one tire and the Wolfbox unit on the other. My old unit took 3:51 (3 minutes and 51 seconds) to inflate 6psi, while the Wolfbox took all of 1:13 to inflate 6psi. So the Wolfbox is 3x faster than my old unit. Quite impressive for being half the size. I love how big the display is. The screen is bright and I can easily read the numbers while standing up compared to the tiny screen on my old unit. It also has cool functionality that lets you set the target PSI, and it will auto-shutoff when complete. There are presets for a vehicle, motorcycle, bicycle, and ball, but you can set it higher/lower than those and also update the preset if you want. While I have not been able to test the jump starter functionality yet, it advertises 3000A compared to the 1200A of my old unit. I'm unsure how that translates to actual cranking amps, but seems to be more than capable for my medium size SUV. Overall, I am quite impressed at the power/functions/features. Coming off of my old unit, it seems to be an improvement in almost every way. The price is reasonable for what you get. Hopefully I won't have a dead battery and have to test the jump starter, but good to know it's there.

Das Produkt macht optisch einen sehr guten Eindruck. Alles wirkt hochwertig und haltbar. Natürlich ist die Größe und das Gewicht nichts für die Handtasche aber dafür ist es auch nicht gedacht. In der mitgelieferten Tasche sind alle Zubehörteile sicher verwahrt und geschützt. Der Akku war zu 70 % geladen und mit einem 65 Watt Netzteil (gehört nicht zum Lieferumfang) sehr schnell auf 100 %. Die Bedienung erfolgt über Taster auf der Gerätevorderseite und dem Display und ist nahezu selbsterklärend. Ich habe die Starthilfe sofort an einem Fahrzeug mit abgeklemmter Batterie getestet und den Motor zwei mal ohne Probleme gestartet. Dabei hat der Akku lt. des vierstufigen Symbols auf der Anzeige fast nichts an Energie verloren. Der integrierte Kompressor funktioniert ebenfalls einwandfrei und ich habe gleich alle vier Reifen des Fahrzeugs auf den benötigten Reifendruck aktualisiert. Auf dem großen Display wird der aktuelle Druck in wählbaren Dimensionen angezeigt und kann vom Ist-Wert mit den Tasten + und - auf den Sollwert gebracht werden. Die Zubehörteile sind von guter Qualität und sitzen stramm und dicht. Auch die eingebaute Leuchte funktioniert gut in drei verschiedenen Modi. Die Powerbank-Funktion habe ich noch nicht ausprobiert aber ich bin überzeugt, dass das auch gut funktioniert. Ein paar Verbesserungsvorschläge hätte ich dennoch: - keine hochglänzenden empfindlichen Kunststoffteile verwenden - die Anzeige des Akkustandes auf dem Display in % angeben - Taster beleuchten oder farbig gestalten für die Verwendung bei schwachem Licht - gegen Mehrpreis gleich ein passendes 65-Watt Netzteil mitliefern Insgesamt bin ich mit dem Produkt sehr zufrieden und empfehle es uneingeschränkt weiter.

Just buy it ! Amazing and works perfectly

Fiable, bueno y de calidad. Lo he tenido que utilizar y ha hecho su función de forma excepcional. Mucha potencia y ergonomía. La funciona de inflado de neumáticos es top

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.

It's absolutely amazing, it started my 2.2 diesel automatic mercedes with a completely flat battery instantly, the torch was handy as this happened when it was dark. I have inflated all my tyres to the correct psi, it stops automatically when the correct tyre pressure is reached which you can adjust easily by pressing the plus or minus buttons. You can charge your mobiles from this also and use it for other usb devices, so many uses in 1 package, takes around 90 minutes to fully charge, apparently it holds it's charge for 2 years, though I would top the battery up every 5 or 6 months just in case, or more frequently if you use it to inflate or check your tyre pressures. It comes in a robust smart case to protect it, the jump start leads grip very strong, it's an excellent quality item from wolfbox, as soon as you open it you will see for yourself. I have their mirror dash cam also which is another amazing quality product. I would honestly recommend this to everyone..
