Jump Starter, 1200A Peak 12V Car Battery Jump Starter Portable Jumper Box (Up to 6L Gas, 4L Diesel Engine) with Smart Protection Jumper Cables, Quick Charge & LED Flashlight

If you have ever been on the side of the road stranded because your car wont start you already know the struggle, or on that cold day when you get inside and go to turn the key but all you hear a click...yup thats the worst.This allows you to jump your car about 3 times before needing a charge. All you do it clip them on to the battery terminal in your car and the car starts right up which is amazing. I was reading how it has about a 1000 charge life cycle. Which is good because the price makes up for it. This is one of those things you as yourself if you need it...you might not at the time but when you do its a big problem. Overall like how it has multiple usb ports as well as a flashlight attached to it. Good for beginner drivers or for those with older cars that need a jump here and there

You get something like this hoping you never need it. I got it to keep in my adapted van so I knew I could get my car started when I needed it.Finally needed it. Had my special needs daughter in the car. And guess what... it didn't work. No charge. Brought it home to recharge and... didn't hold a charge.This is something only needed in an emergency and when it doesn't work, it leaves you stranded.I recommend getting a different brand.

I like the jump starter, it is compact. But there is no wall adapter for charging. Not sure how to charge.

The media could not be loaded. I bought this as a precaution just in case one won’t start. Since None of my cars are broken down I tested this charger using my fluke multimeter to make sure at least 13 volts needed to start my car was being produced. Once this jumper was fully charged, my multimeter read almost 17 volts were being produced. It works! I think I’ll take it out of the trunk once in a while just to make sure it’s fully charged. It’s nice to have a little piece of mind that if my car won’t start I have this in the trunk instead of trying to hunt someone down to help jump my car.

Bought 3. Two were bad out of the box. You cannot depend on this to work when you need it most.

Stopped working before I even got to use it. Doesn't charge, doesn't turn on nothing. Seen quite a few reviews saying this and now I know it's true. They're sending defective refurbished products so it's a hit and miss. Do not recommend at all.

I had purchased this car jumper as a back up to one I purchased last summer. It is a Gooloo brand and it has been fantastic. This ROCBOC model is not as streamlined or as convenient as my first purchase. One major complaint is the ROCBOC model does not come with any sort of carrying device or bag. Nothing. Not even a cheap nylon drawstring bag. Also, I paid MORE for this model, with less accessories, than the Gooloo jumper with a nice case.I charged the unit, unplugging when it was fully charged. Used it for the first time this morning and it did not jump the battery the first try. I had to readjust the clamps and it did turn over then.I am likely going to keep this product and try to find a case for it for easier travel. These usually are stored in a vehicle for emergency use so a carrying case is really necessary.

I wish I had bought it earlier! My car's battery was dead and the juice leaked out a week before the bought it. It thew me in a situation that I was trapped in a parking lot desperately waiting for someone to come and help me jump my car for twice! I didn't know this kind of product could be found here on Amazon until a friend of mine told me after I changed a new battery for my car. I should've got this already and always keep it in my car, in case any battery issue happens again, then I don't have to depend on others to help me.
