A battery jump pack is THE safest bet in the hands of someone who is car smart.
Your cars alternator is NOT a battery charger. It is a maintainer for a fully charged battery. So if the battery is not properly recharged after a jump start then you run the risk of overheating and burning out your Alternator.
Lets see , With Mr. Friendly jump man I have seen. The Battery blown up, Electrical circuits fried from crossed polarity. Damage to computer modules. Even seen airbags deployed from jump starting.
But I'm sure someone will jump in here with " I never had a problem" 
And they usually drive a pre 81 vehicle.
AAA is a good value for these situitions.  |
Ditto these comments.
Last time I jumped a friends car (in 2001), my car wouldn't charge my battery the next morning costing me $300 for a new alternator. Too many expensive computers to risk by jumping a newer car. Get someone that knows what they are doing and charge the battery (or replace the battery if it's older that 3 years old).
