    Had been looking at these for sometime since my last dead battery issue. The person who came to jump my vehicle had a device similar to this one. This one seems to be just what I was looking for although I haven't had a need to jump start my vehicle yet. Reviews and logic seem to indicate that this device will do the trick. Charging cell phone with it went without a hitch. Price was good when I bought it (on sale) so, so far; win win.

    This has been a life saver for me. I bought this as something to have because I thought it was cool. I found out how valuable it really was. My battery was dead in my SUV & I was on the Turnpike at night. I pulled out the jump pack & what do you know it started my SUV up without any problem..I would recommend this to everyone!!!

    Now that I have had this thing for 6 months and put it through its Paces a number of times and happy to say it is everything that was promised to be! And yes, I have jump started 2 cars with dead batteries using the small jumper cable included, and it really did start the cars! Well done.

    Where's this thing been all my life. This will save you money and hassle spent on those SOL jump start situations. Best of all, keep it in the glove compartment. Good for several jumps before needing a recharge. One of the best and handiest gadgets I've ever owned.

    Great for small cars as soon as I plugged it to jumpstart my suv the fuse breaker broke and it's not just replacing the fuse to fix it you had to buy another set of battery clamps from cobra directly :(

    This thing is great. Jumped my 7 passenger Suv in 3 seconds flat, which included the time it took to get in the car to start it. Good enough charge to jump 3-4 cats minimum. Also is a extendable battery unit for all your USB devices.

    I bought this for motorcycle use on tours since it is so small and easy to pack however it will start an 80's V8 car at a pinch. It takes a long time to charge but given the source and power output that's not really an issue.

    I´ve had the previous version of this product, so I´ve bought the newest model, and is great, just that this new model have a fuse, but is not replaceable, but is better than burn the whole item.
