    Item Description

    The Stanley 300-amp jump starter delivers three hundred amperes of current to a twelve-volt battery for instant startup of your vehicle. The Stanley jump starter works on desulfation technology to provide an instant start. The built-in charger enables you to charge the battery any time and anywhere on the go. This convenient portable jump starter works equally well for motorbikes, especially in extreme winter conditions and prevents any choking of the battery. The Stanley 300-amp jump starter is small, easy to carry and lighter than many other battery-equipped units. The complete jump starter comes with a heavy-duty metal clamp in an impact-resistant, injection-molded case.

    • Delivers 300 amps of instant starting power
    • 600 peak amps of power

    Rated 4.5 out of 5★ by 27reviewers.
    Rated 1 out of 5★ by It left me stranded once, and failed me TWICE!!!! I bought this item to keep in my trunk in case of emergency, and I made sure that it was properlycharged before my road trip. As it so happened it was called into duty and simply did not work. The tow truck guy arrived and pulled out his little jump starter box, hooked it up and my car cranked instantly.The other experience i was fortunate to have been at home and had left a dome light on, and this box simply didn't work. I went and had all my electrical systems checked along with the battery and everything came out to be in tip top shape, and i had an electrician friend double check everything for me and agreed that there were no problems at all with the car, but the problem was indeed a fault in this jump starter.I was fortunate that i had kept the receipt, had no problems returning the product. 11/12/2013
    Rated 3 out of 5★ by No Air compressor I have a older version that has air compressor but this one does not. Unfortunately only found out after getting the product delivered. The picture is wrong. I would still recommended it as a battery. 09/15/2011
    Rated 5 out of 5★ by Happy with it. I have had a jump starter before and it was big and heavy. This one is compact and light. I also like the light on the side that moves. 08/20/2011
    Rated 5 out of 5★ by Excellent Product - Excellent Price Am so frustrated continually seeking jump-starts because the battery in my stored vehicle dies ... and the unit I purchased last year from another store to renew power to the that battery requires removing and lifting the exhausted, heavy battery into my home. Now, my problems are solved! 06/04/2014
    Rated 5 out of 5★ by Super Price I'm very happy with my battery changer and the shipping was fast and cheap 02/28/2012
    Rated 5 out of 5★ by Arrived in days and fully charged! Have only used it for a dead cell phone so far but it's a great aid for a car with some electrical issues. Along with a battery tester I know where I stand at all times.A lot cheaper then buying a new battery while on the road. Thank you. 11/29/2012
    Rated 4 out of 5★ by Inexpensive Peace of Mind Luckily, I have not needed to use this item so I can not comment on it's performance. I'll do that when the opportunity arises. The unit feels sturdy and has a nice feature set. I can, however, weight in on Walmart's rapid and inexplicably cheap shipping. The package was 14 lbs. and delivered in two days by FedEx for $1.97. I was impressed. Thank You Walmart 05/08/2012
    Rated 5 out of 5★ by No Need to Be Dependent on Anyone for a Jump It's a great feeling having this in my trunk in the event my battery gives out. 03/10/2012
