How to buy a jumper pack

How to buy a jumper pack

Every big box and auto parts store sells “jumper packs.” But many emergency and portable power packs masquerade as jumper packs. They may start a dead car, but only if the battery is partially discharged. So you need to know how to buy a jumper pack.

Jumper pack peak amps rating is irrelevant

There is NO industry standard test to determine peak amps rating. In fact, it’s a meaningless term. So a pack puts out 900 peak amps? Well, for how long? A millisecond?

When you buy a car battery, you buy it based on its Cold Cranking Amps (CCA). CCA tests are standardized within the industry, so you can rely on that rating. The same holds true when it comes to jumper packs. Buy a pack based on its CCA rating, not peak amps.

How many CCA amps do you need? Well, if you’re trying to jump start a dead battery on a 4-cylinder engine, 200 CCA will do the job. If you’re starting a larger engine, look for a larger pack.
