Compact

Compact car jump starters are generally based on the latest in lithium ion battery technology. This allows them to pack an incredible amount of  jump starting punch in an astonishingly small package. We provide a detailed comparison between SLA and lithium devices in our best lithium ion jump starters article.

Compact units are designed to easily fit inside your glove compartment, keeping them out of sight.  Most units can also serve as powerbanks and as such have been sized to fit into your pocket or a backpack.  They really are the ultimate in portability and can often match the performance of the larger sealed lead acid counterparts.

The Everstart jump starter is just one example – it exceptionally tiny, but still packs enough power to start a family  sized car and even an SUV.

They are also usually made from tough materials to ensure they do not get damaged by corrosive liquids or grease. Don’t think their small size means they are compromised in anyway.

Safety wise, all of the units we review have at the very minimum reverse polarity, short circuit, low voltage, high temperature, and reverse charging protection mechanisms in place to keep you and your loved ones out of harms’ way.

Peak currents as high as 2000 amps are fairly common for these devices, which is generally enough to jump start most family vehicles, SUVs, motorcycles, scooters, boats, and more. Technology has even advanced to the point where supercapacitors have been incorporated into jump starters meaning they don’t need to be charged at all! We cover these in our best batteryless jump starter review post.

Multiple functionality has also become the norm on compact jump starters, with USB and laptop charging, as well as LED flashlighting standard  on most units. Air compressor combos are also available, allowing you to pump up your tires in those unexpected situations when your tires magically let themselves down. With these features however, just be sure you know how to charge a portable jump starter properly to prevent damage to the battery bank and ensure the maximum amount of life from your jump box.

If compactness is your primary concern, you’re definitely in the right place, as JumpStarterExpert.com has done the hard work of finding the best jump starters with the biggest-bang-for-buck performance in the smallest of packages. You’re sure to find exactly what you’re looking for right here.
