Reliable, powerful, and worth every penny
I absolutely love this jump starter. I’ve actually purchased it twice, and it has not disappointed. It’s powerful enough to start my car quickly with no hassle, even when the battery was completely dead.One of my favorite things is how compact and easy it is to keep in my vehicle—it doesn’t take up much space at all. The built-in display is clear, and I like being able to see exactly how much charge it has left. The added bonus of the fast charging feature is super convenient too.It gives me peace of mind knowing I don’t have to rely on someone else or wait for roadside assistance if my battery dies. Definitely a must-have to keep in your car. Highly recommend!

WOLFBOX IS THE BEST!
WOLFBOX 4000A is absolutely the best jump starter you can buy for the price you will pay. It is solid, dependable, and holds a charge for months. There are many good jump starters on the market today and competition for sales is heating up. However, if you want to charge your jump starter, put it in your vehicle and be confident that it will work properly in an emergency situation, buy a WOLFBOX. You will initially spend a few dollars more, but the confidence in the product and “peace of mind” is worth it. I own two WOLFBOX jump starters; the 4000A and the 4000A with air compressor. WOLFBOX Customer serve is the best, by far. They stand firmly behind their products and are genuinely concerned about product quality and customer satisfaction! Between Amazon’s and WOLFBOX’S excellent Customer Service, you will never regret your purchase!

Quality and price are of the most importance and this product checks off both requirements.
WOLFBOX 4000A Jump Starter,12V Car Battery Jumper Starter Portable with 65W Quick Charger works well. I had to use my booster to boost my truck battery just a few days ago, and it performed very well, I was surprised at how easily it boosted my truck , because alot of the time products are hyped up, but this was not the case. It is a great product and well worth the cost. I would advise anyone to purchase this booster to have on hand in case of an emergency.

Easy and fast hook up, lightweight but works like a heavyweight
I love this charger! Very easy to use and charges fast. I really like the fact that I don’t need to run extention cords for electric plugs. Best charger and I highly recommend anyone who drives to purchase one. You’ll be glad you did. If not, remember “i told ya to get one” when your car battery is dead.

Excellent!! Except??
I’ve got an old Chevy. It’s actually a 1995 3/4 ton with a 5.7L motor. It’s no joke. My starter is going bad and so when I go to start it in the 0 degree weather that we have up here in AK, it sucks a lot of juice from my battery and usually I don’t have enough battery power and need a jump. I have been quite pleased with my 4000mhA WOLFBOX. It has started my old truck 5 times in one day and still had over 50% of the battery life left. Quite pleased.I have yet to figure out why it won’t start a side post 12v though. I brought it along when I went to help a friend. He needed a jump start. When we hooked it up to his side post 12v……nothing. I ended up having to get the old fashion jumper cables with my truck on that one. I tried to jump another side post in another vehicle and….nothing. Like the jump box wouldn’t recognize that I hooked it up. I don’t get it. I also tried to jump another newer vehicle and there was nothing until I pushed the boost button. I am still rating this WOLFBOX with 4/5 stars. It’s alright with two thumbs up!!

Worked great on dead (3V) battery
MegaVolt24, 4000A.This thing works and was easy to use. The length of the jumper wires are pretty short, so depending on where the connections to the positive / negative terminals are under your hood, you may need extension jumper cables (proceed at own risk).Day 1: due to single digit Fahrenheit weather, the 12V battery of my 2020 Rav4 gas/hybrid (2.5L, V4 engine) dropped low enough to prevent the engine from starting and the dash from turning on. I wasn’t able to use another car to jump it, so I ordered this portable charger. I figured $120 was way cheaper than AAA or a tow – plus I can use this again and again.Day 2: the battery was so dead I couldn’t even unlock the car with the key fob. Not great.Day 3: this device arrived, pre-charged to 72% (the manual says >50% is needed for a jump) but using the included wall plug & USB-C cable, it charged it up to 100% within 30-45 minutes or so. I probed my car battery and it was dead dead, at 3V and change. I connected the MegaVolt24 to the terminals, it started beeping and indicated “Low Battery” on the display. Based on that, the manual told me I needed to hit the “boost” button on the charger for 2s, then start the car. And bingo, it got the engine going! I drove the car a little but had to jump it again after parking and the total charge of the MegaVolt24 went from 100% to 90% after two jumps.I’ll likely need to replace the battery but this portable jump charger is super handy. Though I’d recommend against leaving it in the car throughout winters & summers as the internal Lithium Ion batteries should stay between -4F and 140F, but will hold their capacity longer if kept around room temperature.

Best investment to have in your car
Definitely better than my previous jump starter, I can actually leave it in my car without charging it or worrying about the heat damaging it, I haven’t charged it in a while so it does have good battery life. I helped someone that needed a jump once and a few others with my old starter, definitely handy, and a life saver in case you need it in the worst case scenario. Safer than your traditional passing cables and you can take it anywhere.Definitely recommend getting one cause I’m getting another one for my car soon

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.
