  • 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

  • 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

  • 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

  • Dependable and easy to use.
Color: Orange
My battery went dead on me at the gas station after I filled the car up with ⛽. Then I got but in the car and all I got was noise. It was time to use those new jump starter I purchased in December 2024. It worked perfectly and it was easy to do. It save me a lot of time and I was on my way.

  • good jump box for the price

  • Peace of Mind, while traveling!
Color: Orange
Works Fantastic. I bought this as a anniversary gift for my husband. We went to work, and someone's car battery had died in the parking lot. So he took the opportunity to use this. Started the car right away. It is light weight, comes with a carrying bag. Does not take up much room. And you can get peace of mind, if your battery does die, and you need a boost, this makes it so much easier, because you don't need a second car, or carry around long jumper cables. ... show more

  • Great to have for road trips
Color: Orange
Build quality: This product is great because of its size and fits in your tool box. Durability: It does the job it's ment to do. I use mine plenty for everything and I even got my neighbor one for his truck.

  • Good Product
Color: Orange
Haven't been using my CRV for a few months and the battery died in winter. Battery was only a year old. This thing was able to start the car in first attempt. Discharges 10-20% charge in one jump start. I have not tried how many times it can start, but I guess 4-5 times on one full charge. But anything more would be above expectation for this price range. For me, it worked to my expectations. the flashlight is a bonus. ... show more
