WOLFBOX 4000A Jump Starter Power Pack with 65W Quick Charger, MV24

I bought this item not expecting much from it as I have a Porsche and not started for months, bearing in mine this has a very high compression six cylinder engine and the original battery is Hugh so after fully charging the unit off I went. Turned the key and just a click from the engine as expected. Fitted the booster as instructed and believe me the instructions are very simple and the unit automatically switched on and saying to start vehicle, well that engine started in a nano second, to say i was amazed is an under statement. I am completely in love with this booster and to top it all off it is saying that i still have 93% charge left so in theory i can start the car another 9 times without recharging unit. This is a fantastic piece of kit. Just make sure you buy the correct amps for your car, 4000 Amp booster will start anything so overkill for most family vehicles, get the 2000 Amp unit in that case as it is cheaper. I highly recommend this booster and I don't recommend much to be honest. I checked the unit to see if it holds charge after 2 weeks and it has retained its charge rate, brilliant. It is a very compact and versatile unit as you can also charge your phones or laptop with it and stores in a very hard protective case. Best buy for me in years.

WolfFBOX 400a mega24 jump starter arrived one day early in its own box vacuum wrapped sealed box, simple packaging non waste wrapping. After a couple of teething problems human error of mine I had unknowingly put the contacts on the wrong battery connectors, after YouTubing I realised this. The anti polar protection is a good thing to have with this device especially when errors can occur. Anyway once they were on the right connectors it started straight away it's an amazing piece of kit I did wonder if I should of ordered the one with the tyre pressure inflator but I didn't and all the same I'm so glad I ordered this one. I looked at many reviews for this brand and NOCO brand but decided on this one I have a campervan and opted for the larger capacity of Wolfbox. It had 75% charge when it arrived. It was so simple to use my van had not been driven for a week and the battery was as flat as a pancake. The pack offers independence in not having to wait for the recovery to come out and a great asset if you are travelling around and maybe end up in an isolated area with no phone reception to call recovery and as long as you keep an eye on the charge left then at least you can get yourself back on the road again. I have recommended the wolfbox to all my friends

Very impressed with this jump starter. It feels well built, easy to use, and has plenty of power to start my vehicle quickly without any issues. The battery holds charge well, and the display is clear and simple to understand. It’s compact enough to keep in the boot but still powerful enough for larger vehicles. The extra features like the flashlight and fast charging are also very useful. Definitely a great item to have for emergencies and long trips.

Excellent. Arrived with 74% charge but charges to 100% really fast. Started my totally flat Range Rover first time. The storage box is great and keeps everything in one place. Wolfbox, leads charging adapter and charging lead. very happy with my purchase

I bought this jump starter as a bit of a sceptic. I’ve had them before and none have worked. I have a 2.5l diesel Land Rover discovery which I use for off road trips and camping trips. One of my fears is being in the middle of nowhere overnight and you wake up to a flat battery. This has completely removed that fear! I’ve used it loads of times now and it starts the car first turn of the key. Even when the battery has no power to even unlock the car you just hit boost and the car comes to life. Highly recommend, every car should have one!

came on time good price, charged up quickly but havn't needed it yet

Bought it yesterday since I found out that the one I initially bought didn't do what it was suppose to do. My wife's car doesn't run that often and this morning had to move it, as it didn't turn over again I unboxed this new pack and connected it. It had 75% capacity which was good. She turned the key and the car started straight away. This saved us lots of hassle trying to get my car in front with jump leads. Well recommended. It also comes with a case to hold the pack, leads and charger.

A great piece of kit. Small powerful. simple to use with a very clear screen.

Immer nach monatelanger Standzeit springt sie nicht an, meine Harley Davidson softail herritage. Bislang immer zeitaufwendig Starthilfe über den ADAC bekommen. Habe aufgrund des Testsieges die Wolfbox 4000A bestellt, die innerhalb von 24 Std. geliefert wurde. Kurz von 72% (Auslieferungsladezustand) mit gelieferten Ladegerät an der Steckdose auf 100% geladen. Mithilfe der detallierten Anleitung an Batterie der HD angeschlossen. Nur kurz den Startschalter gedrückt und die Maschine sprang sofort an. Ich kann dieses Tei nur wärmstens empfehlen und bereue es nicht schon viel früher gekauft zu haben.

Excelente producto para salir de las emergencias

Great, until now. Didn't have the chance to try yet. Small size, powerful, and charges fast

I have a Honda Element that I don't use much, and consequently the battery is always running low (especially if I forget to put it on the trickle charger). I've been caught a few times where it will act like it's charged and start up the first time, then after I've driven it to my destination, it won't start again when I need to drive back home. So I needed some insurance. I decided to buy this Wolfbox after seeing it tested, with very favorable results, on the Torque Test Channel. Even so, I was skeptical that such a small box could actually start a car engine, when the car's regular battery weighs like 25 lbs (small for a car battery, but still). But I tried it with a "mostly dead" battery (enough that the power locks worked but it chugged maybe 1 time when I tried to start it). It was night time so I turned on the integrated light on the Wolfbox - plenty bright enough and well positioned to see what I needed to do to hook it up. It took less than a minute to hook up, including finagling the hood open - way easier than dealing with jumper cables or the plug-in charger. The green START light lit up and I turned the key and the car started RIGHT up. I was shocked - the starter actually sounded like it had more pep than when using the regular battery to start normally. The best part is that I started with the Wolfbox at 100% charge, and after starting the car, it still read 97% full. I could drive the car around all day making multiple stops not worry about it with one charge on the Wolfbox. Also the included charger charges it super fast - it arrived about 70% charged and was charged to full in less time than my phone usually takes to charge (and it has a way bigger battery inside). Speaking of charging, I also used it to charge my phone using the bidirectional USB C port - kept my phone running at 100% using it as a hotspot for a whole afternoon, and only depleted a couple of percent of the battery. So this product gets an A+ from me. We'll see how the longevity is but it can't be worse than the regular car batteries. Which brings to mind a question - why are we still using lead car batteries when this lithium technology is clearly better AND cheaper?
