There were models with lower amps and cheaper but decided to pay a bit more to get the extra cracking if I ever needed.

Wolfbox is better known for their dash cameras and I’ve had one installed in my Promaster cargo van for over a year now. So I tried this Megavolt24. Lithium WH capacity greatly exceeds other jump starters (Noco etc) at this price point in Ontario Canada and it also does USB power bank and flashlight functions. Build quality is excellent and the unit feels like a brick. Very nice product presentation too with the retail packaging, welcome instructions and soft shell box for all the components. Recommended!

This is well presented in a box and travel case and will store neatly in the car.The booster took its charge from my Samsung charger so easy to use. It took about 1 hour to boost from 78% to 100% max charge. Love the lamp which can strobe and send SOSNeeds to be charged every 3 months for best performance.Good booster pack and well.made.

Rare that a product exceeds my expectations, but this one did. Ordered it to recharge a dead truck battery, which happens a few times per year because I drive it so infrequently, especially when it gets colder. In the past, have to position another vehicle, open hoods, connect cables (and fidget with them until I have a strong connection), start up the truck, disconnect the cables from both vehicles, and drive the “charging” vehicle back to the carport. The Wolfbox was great. Spent about a half hour charging it to 100% after It arrived. Connected it to the truck battery (could not have been easier), and truck started right away. Only used up 3% of the Wolfpack charge. All within five minutes or less.Quality is superb. Comes with a very nice storage case. It’s lightweight. It will also charge other devices like tablets, computers, and phones. As we live in earthquake country, as well as regions threatened by power outages due to fire, the charging versatility of this device is incredible.There are other much cheaper alternatives out there, but from my perspective, this is worth every penny and more. Rarely offer any kind of product endorsement, but felt compelled to give this one.

I like everything, I love the protective box it comes in and the ease of use also.I actually started an 18 tonne truck with it on boost mode, started first time no problem.I’m really pleased I bought this unit.It was a great price also compared to similar items.

I was very pleased how the battery jumper starter works.* The display showed the status of everything. It is very clear (be sure to read the instruction).* The battery status dropped about 2 to 3 percent after press the booster button. It applied to my SUV.. If you need to do another booster button, it would give you plenty of power available. More likely, you would just need one incident of using booster button.0* The weight of the starter, bag, etc is almost 3 pounds. The size is very reasonable. I was shocked that the case is small and powerful.* USB-C will recharge very quickly.

I love how portable, lightweight, small size, quick charging and affordable this device is. My only concern was it did not charge the dead battery in my Suburban. It charged my Mercedes battery immediately. AAA came out to jump my Suburban battery and it started right up with their portable charger.

The Wolf Box is small and slender great to have on board any car or truck I just got it and was close to being fully charged and ready so I wanted to try some of its features. I used both USB options to power cell phone and wireless speaker to play some tunes. I was amazed on after using it for over an hour how much battery life was still in the Wolf Box. Since it is brand new haven’t used the jump start features when I do I will post a comment. Also the Wolf Box is light weight so if you go camping or to a picnic and want to power up something you be dragging something heavy around….for now since it is brand new and I haven’t had a chance to play around with the jump start to much I say I am happy with it so far.Oh the charging time is super quick and the jumper starter has a boost feature for the dead car battery that gives you a fit..

I got this product in case my car doesn’t start in our cold Wisconsin winter. I am a single 68 year old female and don’t know anything about jump starting a car. I have had problems in the past where someone would jump start my car for me but I wanted something I could do on my own. After researching and watching videos, I decided the Wolfbox was worth a try. I got it, charged it, and in about 3 weeks I went to start my car and it wouldn’t start. I read the easy to follow instructions and in a matter of a few minutes my car was running with no outside help! The directions are easy to figure out even for someone with no knowledge of what to do. It still said that it was at 98% charge after I used it. It comes in a sturdy case with room for all accessories. It has a phone charging port which is a bonus. It has a boost feature to use if the regular charge isn’t enough. (I didn’t need to use it.) Also, for those of us that are apprehensive because we’ve heard about batteries blowing up because of puttin the clamp on the wrong polarity, there is an alarm that will tell you before you go any further. I never review items but am making an exception in this case because I am so thrilled with it! It is easy to understand for an amateur and has given me great peace of mind. The Wolfbox is worth every penny!

This is so easy and it works!! Literally there is nothing to it…plug the unit into an electric socket and charge to 100%. Unplug unit and go to car needing jump start and follow simple instructions (it shows which color clip goes to which battery terminal). Soon you will be able to start your vehicle. The unit is small and light weight…has a light so you can use in dark and emergency flasher if you need it for visibility. So, I repeat, this charger is so easy and well worth the price in my opinion!
Amazing Customer –
I would highly recommend this product. I knew it was cold out and my jumper cables were getting old, so I decided to buy this instead. I used it TWICE 2 weeks after I bought it and it started my car with no problems. It got me to the auto parts store so I could replace the battery. I didn’t even need a second vehicle to jump start my car. It was fast, and very easy to use. Great product and it has a compact case for storage.

This little battery jump pack works great for a fraction of the price of the competition. Good power and easy to use. The battery seems to hold a charge for a good amount of time. It went 4 months without use and only lost 2% of a charge. Seems durable. Nice features like the light and USB charger.
