I think its a really good device to have in your car, but it does have some caveats. Unfortunately, like in the video, this does not work on a diesel double battery vehicle but works flawlessly with any other single battery vehicle. It will not charge the battery enough to where the diesel truck can start. It's pretty light and the battery carries most of the weight. I don't recommend storing the battery in the car 24/7 as it can cause issues with performance and its storage ability. I usually just carry my battery with me every time I go in the car and take it back in when ready. You can also put it in an Insulated bag to keep it cool during hot days. You can also charge your phone with it, as it has USB ports, and LED lights for illumination. Overall, I think its a good battery charger/booster but I think if you're looking for a jump starter, than this would be too expensive for your needs, and I think a regular jump starter would fit better. If you're looking for a battery booster that can charge your battery and also be used in an emergency, than this unit is great.

As always, dewalt made a fantastic product. The product provides an easy portable jump starter with many other cool features. The device itself is quite compact and works well.

The DEWALT Professional Battery Booster Kit is a dependable and well-designed solution for vehicle emergencies and everyday charging needs. The included 20V lithium battery charges efficiently and offers strong capacity, providing plenty of power for multiple boosts and device charging. It’s highly effective at jump-starting low batteries, making it a reliable tool to keep on hand. The unit feels sturdy and easy to use, with smooth application and comfortable handling. A standout feature is the built-in LED light, which is especially helpful during nighttime situations or low-visibility conditions. It also includes two USB-A ports, making it easy to charge phones and other devices—particularly useful during power outages. On top of that, it operates quietly compared to traditional jump starters, and its durability ensures consistent, reliable performance whenever you need it.

It’s quite different from what I normally use. But it is very convenient and portable. Easy to use and plug in and charge fast. The tool is light weight and material seems to be durable. Love it so far, very affordable too
