We had an issue last summer when the battery switch was left on and we found both batteries dead the next time we tried to use the boat. We had to take one of the batteries home to charge it and lost a beautiful day of boating. This year, I bought one of these for myself for Father's Day to have on hand just in case. Not even a week after receiving it, the same thing happened with a friend's boat, but this time we had our Uibi jump starter in the car. We jumped a 150 HP outboard with no issue and it only used 2% of the charge! A couple of days later, we lost power in our cottage and used it to charge a nearly dead phone. One of my better purchases for sure.

As a concerned father, I wanted to ensure my daughter wouldn't have to rely on strangers to jump-start her car in an emergency. That's why I purchased this portable jump starter for her to keep in her vehicle. And, boy, am I glad I did! We recently had a situation where my car was stranded with a dead battery, and this device came to the rescue. The LED lights are incredibly bright and provide excellent visibility. What really impressed me was how long the charge lasts - even after a week, it still shows 98%! Plus, it's a lifesaver for charging phones in emergencies. I highly recommend this product to all fellow worried dads out there who want to keep their loved ones safe and prepared on the road.

I was surprised at how small this was. It's a lot smaller than the old battery jumpers you would keep in your car. It's a great thing to have especially in the winter. As a safety. You can charge it with the cord that it comes with. It was really great quality. It would be a great gift or an item to get a new driver.

This thing is small and compact and pack. A huge punch definitely worth the money crank just about any engine and any condition battery wise. And you can use it as a power device for your devices and what have you

I had problems charging it the only way I can charge it is in my car when I’m driving I have not tried it yet so I don’t know but it looks a good one

I enjoy the size of this product. I have several small engines and an old truck that I have to jump on a regular basis. I have used this on them over the last week and it has worked well! I really enjoy the size of it that I can just throw it in my back pack and use it to recharge my phone as well. It charged my iPhone quickly. The clamps hold well to the battery post as well! I’m actually thinking about buying another one to keep in my wife’s car.

This product works great. I like that it is small and portable. it could easily fit inside the glove compartment in your car or in the door storage compartment. Overall great product for the price.
