4000A Jump Starter Power Pack with 65W Quick Charger, MV24 | 10L Petrol / 10L Diesel, 12V Jump Pack with Boost, 24000mAh, 88.8Wh, LED Torch, Power Bank, Portable Battery Booster Pack

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.

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.

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

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

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

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

Arrived with 16% power. Charged to 100% in less than hour & a half. Started my flat 3.0 (c320cdi) Mercedes turbo diesel instantly, using charging point rather than directly on battery. Used 4% according to display. Very well made, high quality materials throughout it would seem. Time will tell if this is better than a £30 booster, but so far I'm very happy.

Charging is quick and vehicle started right up - No hesitation. Wolfbox is powerful and compact. Great product.

Totalmente efectivo y práctico.

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

Zeer positieve ervaring met de verkoper. Kort na mijn aankoop bleek dat de Wolfbox 4000A jump starter was afgeprijsd. Na contact met de klantenservice is het prijsverschil netjes en snel terugbetaald, zonder discussie. De communicatie was duidelijk en professioneel. Dat noem ik correcte en betrouwbare service. Het product zelf maakt een degelijke en robuuste indruk en voelt kwalitatief aan. Ik heb de jump starter nog niet daadwerkelijk op een auto hoeven testen, maar op basis van de afwerking, specificaties en de vele positieve YouTube-reviews van andere gebruikers heb ik er alle vertrouwen in dat het apparaat doet wat het belooft. Alles bij elkaar ben ik zeer tevreden over de afhandeling, de service en de manier waarop met mijn verzoek is omgegaan. Dat geeft vertrouwen en maakt dat ik deze verkoper zonder twijfel kan aanbevelen.
