Not really sure how to politely say I have no opinions in this topic and really want to emphasize I really like "ishoot308's" posts. (Would love to learn some of his fishing tricks) But the video link posted above and what they are showing in the demonstration is really not a good thing to do. The test is a little misleading in one way by starting/ cranking the engine with the original / old maybe dead battery disconnected not a fair test. But that's not the real concern. The real concern is if you do get the engine started with just the "jump pack" with the main/ existing battery disconnected and then one of the leads using the alligator clips becomes un-done /disconnected for a split second, goodbye charging system on your boat or car in most cases. The video kind-ah suggests you could get the engine running then re-connect everything while the motor is running. (Never do this its a very bad idea.)

From the link below:

The moment he disconnects either lead from your battery, it's entirely possible he caused thousands of dollars in damage. Here's why...

Your battery does more than just provide electricity. It also shorts AC, spikes and transients to ground. Removing the battery from the circuit allows those spikes and transients to travel around, endangering every semiconductor circuit in your car. The ECU, the speed sensitive steering, the memory seat adjustments, the cruise control, and even the car's stereo.
