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

Really impressed with this starter pack I have a 2-litre pickup that doesn’t get used all that often, so the battery is usually dead whenever I come to use it. I bought this as a replacement for my old jump starter, which randomly stopped working one day. First impressions are really good. It’s very easy to use and comes in a nice little carry case, so it’s easy to keep in the vehicle. It comes with the charging cable and plug, and it charges surprisingly quickly. One of the biggest things I noticed is the size. As you can see in the pictures, I’ve put it next to my old starter pack for comparison. This one is considerably smaller — roughly three-quarters of the size in length, width and depth — and it looks much better as well. At the time of writing, it was less than half the price of my previous one, and considerably cheaper than something like a NOCO. Despite that, it works incredibly well. The screen is clear and bright and shows you the exact percentage of battery remaining, which is really handy. On my pickup, each jump start uses around 4–6% of the battery, depending on whether I use the boost function. So you’re getting a LOT of jump starts from a single charge. It also has a torch with multiple light modes (shown in the video), which is honestly a brilliant feature. If you’re out somewhere in the middle of nowhere and it’s dark, you can switch the light on, see what you’re doing, connect the leads and get the vehicle started without having to mess around with a separate torch. It gives me a lot of peace of mind knowing that if I’m out in a field somewhere and the pickup decides not to start, I can just jump it myself rather than having to rely on someone else. I’ve included a video showing it starting my pickup. The truck wouldn’t start, I connected this up and it was running again in around 30 seconds or less. For the price, size, build quality and ease of use, I’m really impressed with it. It does exactly what I bought it for and seems to do it very well. Highly recommended

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.

Bought in April as a "just-in-case" purchase before a big road trip, never had to use it until yesterday, unit was still on 100% after sitting in the car for last half a year and only used 4% to jump start my 5.0L V8 Mustang. Great piece of kit!

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

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

First class jump starter, used on a Land Rover Defender td5 which had a faulty battery, the vehicle battery was showing 9 volts, connected the WOOLFBOX and it started effortlessly with a flick of the key. Would highly recommended.

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?
