This is by far the best investment I have ever made. There are not many things more frightening than being alone, late at night, with a dead battery. It is a dangerous situation for anyone but me, as a single female, it is terrifying.

This jumper box is the best investments I have ever made. The entire process from start to finish is less than three minutes. It is so easy to use. First, you take the box out of its carrying case and plug the cable with the red and black clamps into the jumper box. Next, you connect the red clamp onto the (+) positive terminal of your dead battery, after that connect the black clamp onto the (-) negative terminal of your dead battery. Toward the end of the cable, near where it plugs into the box is a little button, push that button. Finally, get back into your car and turn the key. The car should start right up.

I have used this box on my 4-cyl. car, a 6-cyl. SUV that was completely dead, and on a 8-cyl. 4x4 truck. Each time was successful the very first try.

The jumper box has two USB charging ports to charge your phone and devices. It also has a very, very, bright flashlight with three different modes, one is an emergency flashing mode.

You charge it with the charging cord that is included.

I first bought one for myself because I had recently left my lights on at school. I had been using my interior light to study in the parking garage before class and I forgot to turn it off. It was the final class of the evening and not many people were at the school.

After class I got into my car, turned the key and nothing. My battery was dead. There was only two other cars in the parking garage. My phone was also dead. It was dark and I was scared.

Finally, parking enforcement came along and they successfully jumped my car. This was almost an hour later.

Right there I made up my mind that that would never happen again. I had heard about these little jumper boxes that fit inside the glove box. Honestly, I was skeptical. I took my chances, after some research, and purchased this jumper box. It lived up to all of my expectations.

I was so happy I bought one for my 80-year old mom, and my son.

Seller was quick and helpful!
Nice little box, has the juice to boost several batteries in a row. I would recommend for personal use. It can boost the battery on my car, and one of the 2 batteries on my diesel flatbed.

Used it for less than 6month, worked perfectly for those period. Surprisingly it just went off. Didn't last as long as expected.

Worked great for me. My battery wasn't completely dead, but the car wouldn't start. Hooked the little box up and it started like a champ. I have my doubts whether this would work if your battery was completely dead, but if there's a little bit of juice (but not enough), it does the trick. It's convenient, too: after starting up, you can hook it up to a car charger to juice it back up in case you need it again. Small enough to toss in the glove compartment, and you've got yourself a spare device charger and flashlight.

I bought this device after having somehow left my lights on in my car. I called a company that could be out within 30 minutes and use a portable car jumper and they quoted me a price of $216! I decided to purchase the Biuble Car jump starter since the videos seemed very authentic. I can say after you can go to device only one"¦ It works Believe it or not it truly works! The device is not complicators and when it arrived, it was 75% charged. I did follow the directions and let it charge fully before I tempted to jumpstart my car. Within five seconds of advice, my car started with ease. Well worth the money spent and I'm blessed for the money saved and Peace of mind
