The media could not be loaded. This is such a great product at a competitive price point, especially if you like to be prepared. With this portable jumper starter, you’re able to jumpstart your car without needing to rely on others for help. Works perfectly as described, and is small and portable. Comes in a nice bag that you can leave in your trunk that does not take up any space at all. Would make the perfect gift for any adult!

I have had this for a year and used it for charging phones and jumping cars. Holds a charge for a while! Sat in my car unused for 6 months, neighbor borrowed it to jump his battery. It worked on the first try! Fantastic item! I also purchased one for my son. He has not had to use it yet, but was happy to receive it!

This lightweight battery pack was almost fully charged upon delivery and sat in the truck for a couple months. It held its charge and when I needed to use it to jumpstart my car, worked perfectly. It instantly started the car upon both clamps touching the terminals however so keep that in mind when using it. You don't need to press a button to deliver the charge. Also only drained about 20% of the battery to jumpstart it but the battery displayed 0% until a few seconds after I plugged it in to charge it. Overall I'm very satisfied with this purchase and it saved me a hassle when my battery died.

Bought this jumper because I have an older car that is always iffy. I have had to use it 3 times this past winter and I am so thankful I had it. It never fails I was nowhere near help Everytime I needed it. It charges up quickly which is wonderful because I work late nights. Great product!

Just got it because one day I was doing Uber Eats and while waiting for orders I was listening to the radio and when an order came in my car didn't start lol. So had to canceled and my sister came to the rescue. I got this booster and it starts my car fast, love that I can also charge my phone also. And no,, I don't listen to the radio no more. Lol. I do recommend.

This is the perfect portable jumper starter easy enough for my daughter to use with easy connections to the battery terminals. Hopefully she won't need it, but inevitably the time will come when she needs to deal with a dead battery and someday she will appreciate that this is in the trunk of her car in the handy case. The USB port chargers, flashlight and compass are convenient bonused just in case she ever needs to charge her dead iPhone or needs a flashlight for an emergency.
