  • Great quality product worth every penny
Color: Orange
Why did you pick this product vs others?: This thing is awesome. I think every woman in the world should have one. I ordered it on a flash sale, not even believing that it was gonna work for real and now all my friends call me asking me to jump their cars when their batteries go dead this is very simple to use. It’s very small you could fit inside of your glove compartment. That’s how small it is. It’s a great quality. It’s a two step process to jumping your battery. You literally hook the cables up press the boost button and then start your car in your car starts right up. It’s a great qualities so far. I’ve had it for a little while now and every time I have to take it out to use it. It has been charged since the day that I’ve got it so it does stay charged for a very long time. I’m not quite sure how long yet cause mine has not died. I still have 100% battery life and I’ve used it three times ... show more

  • Small and does the job
Color: Orange
Oh, this charger does the job! One always should be prepared for any eventuality. I used this baby to jump start a car that I neglected to start up for months. It worked really well! The charge started the car, a dead battery no less despite its size. It has usb connections, so it can be used to charge your phone in case of an emergency. It has a light that stays on or flashes according to what you may need. It’s a bright light, so it will be seen from a distance when you use it when stranded on the side of the road. Charge it overnight and is ready to use! Read the instructions before using it. This is a great source of power in any emergency. I am planning in getting another to leave at the house for emergencies. ... show more

  • Power Jump Starter a MUST HAVE
Color: Orange
My 2011 Lexus Hybrid was sitting for 3 months. I called AAA for a jumpstart. The technician told me to drive it around town, preferably the parkway, to give the Hybrid battery what it needs. I tipped him $20 and he was gone. I drove it maybe 30 minutes around the neighborhood. The next morning, it would not start. I went on line and found this beauty, nicely priced with same day delivery. It was waiting for me when I returned from work. It was charged 3/4 out of the box so I plugged it in for a full charge, followed the directions hooking it up to my car’s battery, made sure to press the boost button and voila - a super quick charge. This little doozy has power! I did drive it on the parkway and around town for a solid hour and all is well! I purchased one for each of my children to keep in their cars. It’s a solid instrument & a total must have; easy to store in the car in its carrying case (which is included). Oh, and the flashlight feature is a real bonus. As long as you keep it charged, it’ll save you a load of money and hassles when you need it! My only regret is not purchasing this before calling AAA. ... show more

  • Easy to use and worked every time (so far)
Color: Orange
One random morning my car refused to start (repeated clicking with flashing console screens). Wasn't sure it was a battery issue until I called my insurance for a jump start. Bought this after doing some research, for the price this is a great product for a peace of mind and time saving (those jump start folks still takes time to get to you). It appears to be relatively well built. I have since used the product 3 times and t has worked every single time so far and have saved me the headache of calling for a jump start. The carry case is just a drawstring bag, so nothing to write home about. It charges relatively quick and uses about 25% of the battery per use so far. I would recommend charging it back to full after every use or periodically topping it off to ensure it has enough juice. I only have 1 car so it's not a huge problem for me, but for folks with multiple cars, they may want to get a unit with a bigger battery capacity. ... show more

  • It's a good jump box, but looses power quickly
Color: Orange
It's a good little jump box. It's portable , has a flashlight and USB ports. I've only used it to jump my riding lawn mower. The only reason I'm giving 4 stars is because once the battery drops below 75%, it won't start the mower anymore until I charge it back up to 100%. I wish I could get some more power from it when the battery starts to drain. It works fine, I just have to keep it charged all the time, which might not be ideal if you're using this in a car or truck. ... show more

  • Great value and quick and easy to use.
Color: Yellow
I bought this recently and it works very well. It arrived about 50% charged and I immediately fully charged it. It was very easy to use and the clamps stayed securely fastened while on my battery post while jumping my car battery in garage. I got about 4 jumps out of it. The emergency light is nice and the usb charging ports for other devices are handy. This will make nice Christmas gifts this year. Great value also. I hope it lasts a long time. Quick and easy to use. ... show more

  • It works, don’t procrastinate and get stuck on the road
Color: Orange
This thing works! I have used it five times now. People at work made fun of me when I said I could use this so the didn’t have to shuffle vehicles around to jump a buddy’s truck. I connected it up and told them to turn the key and it fired right up. Just today I leave work to drive home and my battery was dead. Connected this thing and pressed the boost button, turned my key and my truck fired right up. It got me to an autozone so I could buy a new battery. Life saver this thing is! Get it and you won’t regret it. When using it multiple times the battery will drain quickly. Keep it charged and don’t forget about it! I got 5 jumps out of one full battery. It’s now charging since I used it and then it goes back into my truck. ... show more

  • Comes in handy!
Color: Orange
Not gonna lie, I didn’t think this would be worth it but I was WRONG! This bad boy has saved my life multiple times when my car was giving me problems. Super easy & safe to use! I think everyone should have one of these as back up.
