How We Decided

In order to narrow down to the above list, we focused on reliability, running the jump starters through a myriad of tests, ensuring their ability to jump start a wide variety of vehicles, favoring products that are rated for use with both gas and diesel engines with support for gas engines up to 8.5 liters and diesel engines up to 6 liters.

We didn’t just rely on stats, though a high peak amp and cranking amp volume are nice, choosing, instead, to actually run them through their paces, checking to see how long they took to reach a maximum charge and how much standby time they offered once they achieved that charge. We also made sure each product on the above list boasted the ability to jump start a vehicle numerous times on a single charge, up to 40 times in some cases.

We also took a look at each product’s additional features, choosing packs that were easy to use, with reverse polarity alarms and other safety forward technologies that helped take the guesswork out of jump starting a car’s battery. We were also impressed by the number of products we tested that could double as external batteries for smartphones and gadgets, with many featuring USB ports, wireless charging capabilities and laptop adapters.

Finally, we liked portable and compact models that were easy to stowaway in a glove box or the back seat when not in use and those that were made from durable and long-lasting components. And if they couldn’t do that, they included other extras, such as a built-in air compressor.
