My advice take it or leave it, is unless it's really absolutely necessary is to avoid using a battery or booster to start a car take the battery off and charge it 
Often it doesn't take too long to get enough charge in it for it to start a car.

Russ - do you know whether any of the cars that suffered from spike damage had been jump started using a power pack?
My personal order of choice is based on avoiding connection/disconnection to an operational alternator as much a possible in order to reduce the likelihood of a spike resulting from inductive or regulation components reacting to the sudden load changes. So, circumstances allowing, my order of preference for starting a car with a discharged battery is as follows:
1. Remove battery, charge, reconnect.
2. Use an intelligent maintenance type charger in situ for a few hours.
4. Use my spare fully-charged battery as a source for a jump start.
5. Use a power pack as the source.
6. Jump start car to car, with the donor car's engine switched off.
