The WOLFBOX 4000A Jump Starter is hands down one of the best automotive purchases I’ve ever made. From the moment I unboxed it, I was impressed by the build quality and thoughtful design. It feels durable and well-made, yet it’s compact enough to fit easily in the glove box or trunk without taking up much space.Where this device truly shines is in its performance. With 4000 peak amps, it had no problem jump-starting my truck’s completely dead battery in freezing temperatures. It worked flawlessly and gave me peace of mind knowing I wouldn’t be stuck waiting for roadside assistance again.Beyond jump-starting, it doubles as a power bank with USB ports and even has a bright LED flashlight with multiple modes – super handy for emergencies or camping. The LCD screen is also a nice touch, showing battery levels clearly.Pros:• Massive 4000A peak current – starts large engines easily• Fast-charging USB ports for phones/devices• Rugged, portable, and easy to use• LED flashlight with SOS mode• Comes with a sturdy case and quality cablesCons:• None so far – it’s exceeded my expectations in every wayIf you’re on the fence, don’t hesitate. Whether you’re commuting, road-tripping, or just want to be prepared, the WOLFBOX 4000A is an absolute must-have. It’s reliable, powerful, and could truly save you in a pinch.

Don't be put off by the lo price. This thing is powerful and well made. It works better than all of those expensive brands I'm ashamed to say I bought 😅. It's very easy to use an comes in a heavy duty case to protect it. Make sure to fully charge it before you use it. Which shouldn't take long because it comes with 80% charge. To turn on just press an hold the power button for 3 seconds. I jumped off 2 f150 super duty trucks and a Honda sedan in the same day without recharging. I had 57% left. I definitely feel I got more than my monies worth💪🏾👍🏾.

Without having to depend on others with jumper cables to start my second car, I decided to buy this. And I am THE absolute worst with instructions!!!! This is very elementary and extremely, extremely easy to do!! So for those of you like me, who aren't very good at instructions,you will love this!!!! I tried starting at the regular way and that didn't work. So I used the booster feature and my horn kicked in, so that's what I needed, was to use the booster!! It's definitely a no brainer & I highly highly recommended!!!!

I ordered this one since my previous bulky jump started failed to jump start my Lincoln MKT that had been sitting unused in the garage for several months. It was a last ditch effort before I would have to call a towing service. The Wolfbox arrived the next day at 70% so I charged it to 100% in less than 1 hour and off to the garage. Hooked up the new unit and it wouldn't start the car. On closer exam the unit displayed Low on the screen , so following instruction I pushed the Boost button and the car lights came on and and it starteded immediately. Drove the car out of the garage and off for a 20 mile ride to charge up the battery. Strongly recommend this unit. It really is powerful and far superior than three other units I have had over the years.

I bought two of these to go into graduation gift baskets for nephews as they were moving out of home. They are easy to use and were a great rescue when they needed to get to work. Value is good, compact and portable so cable lengths are short. I will buy more for additional "welcome" to adulthood baskets.

My Jeep had a dead battery for 2 weeks until I could get to it. I mean dead...gone...not working.I hooked up the Wolfbox and tried to start the car... nothing.I then clicked on boost.. and boom the Jeep started up like a charm!If you've ever had a Jeep you know they can be unpredictable and a work in progress. Having the Wolfbox gives me a piece of mind that I won't be stranded!

My 6.4L Hemi is notoriously hard to jump when it’s really dead. AAA has sent tow trucks with jump boxes that don’t have the capacity, my other cars can’t get the job done, etc. I was skeptical that this compact jump box (The 4000 model) could get it done, but it handled it with no problem. It needed the boost on, but that seems normal and I have no problem with it. I’ll have this in my vehicle at all times and I’ll probably buy another for my wife. Totally worth the price. Couldn’t recommend it more.

I love this thing. The alternator in my truck was going bad. I used this , after fully charging it, 4 different times to start a 50 year old 350ci engine. It started rite away and only consumed 6'/. of capacity.
