Has anyone here purchased the Cobra Jumpack and if so do you have one for your car and have you used it. Just wondering as it would look like a good emergency starter with small cables and something easy to store.

Few if any jumpacks will be able to maintain enough voltage for the electronics in an XK/XKR during start with a dead battery to run this car without crashing the computers....and this is one of the smallest I have seen. Forget it...it won't work.

It perhaps can start a 1.8L 4 banger with few electrical options....on a good day.

 

BluePoint (Snap-On) jump pack

I know for absolute certain that one of these will work without causing any issues. Though the amp rating between this and the cobra one are very different. I would think the cobra one would be good for most vehicles that don't have insanely temperamental electronics systems like modern Jags.

 

Yes I have seen these as a friend of mine has a couple at his shop. They seem to work great but the thing I was interested in with the Cobra was it's size. Thanks
