WOLFBOX 4000A Jump Starter,12V Car Battery Jump Starter with 65W Quick Charger,LED Display,24000mAh Portable Jump Starter Battery Pack(10L Gas 10L Diesel Engine) with Booster,LED Light,Jumper Cables

I bought an EV charging station from them recently and I can't say enough good things about their customer service and support. I got responses within minutes and they have been in constant contact with me and pushed multiple firmware updates to my unit based on feedback and request I submitted. Great company. Amazing support.This portable jump starter and mobile charging unit is well built, top quality, and fully functional. I've verified it fast charges my Pixel 9 Fold and can fully power my MacBook Air 15". My power went out the day I got it, and I used it as a long-term light source. It was bright and used almost no power during the outage to keep my underground house well lit.I have other mobile jump-starting units, and they can be a bit tricky on how exactly to get them to start the jumping process. This unit takes all the guess work away, as all you need to do is connect it and it will automatically power up and start the jumping process when you turn the key. No sequence of key presses or order of operations to remember years after you read the instructions. Has plenty of power for most 4, 6 and 8 cylinder engines. And can start them multiple times on a single charge, depending on how drained the car battery was when used.The instructions are mostly well written and straight forward. The only thing you really need them for is to know how/when to use boost mode vs normal mode. The bottom line is use boost mode (power it up by holding the boost button) when the car battery voltage is below 9v. The instructions are a little unclear on this point, but I've verified though other sources that this is the correct way to use boost.I'm very happy with this unit. It came well packaged, the carrying case if very well built, and the unit itself is solid and sturdier than my other more expensive units.

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.

This jump starter is a beast in a good way. It can handle jump starting a big 10 liter gas or diesel motor. The cables are heavy duty. It comes with the cable to charge the Wolfbox and has a built in light. There is a digital display that shows the amount of charge left. It's portable and well worth the cost. It works great and gives you peace of mind knowing you have the ability to jump start your vehicle s.

This is a great value for the money. It is compact and easy to carry. I love that there is a flashlight, really more of a beacon. It works great. It is really well made. I feel a bit more secure having this in my jeep. This would be a great gift for anyone who has a car!

Thankfully, I have not had to use it yet. I bought it after helping a friend with his 2500 Chevy needing a jump with no one around. Hopefully it is just an "insurance policy" I carry in my truck and check the charge on every so often. BUT>>>> It worked great for my friend.

This is an amazing power supply to make a dead battery work! Gives an extra peace of mind. Small, convenient and holds it’s charge to work when it is needed.

After receiving it I had a problem starting my Kia SORENTO Hybrid. It was totally dead. I connected the jump starter, powered it on but had to hit the boost button before I could deliver enough power to the car to start the hybrid. The screens on the dash lit up and I was ready to go. Great tool and I will never be without it in the future. It provides a sense of security knowing if your battery goes dead there is a simple way to charge it and start your vehicle.

This is extremely handy and often works better & faster than cables. First introduced to a portable jumper by law enforcement, made sure the church had one, now home as well
