When your car battery dies, traditional jumper cables are a great solution to boost it, assuming you can call roadside assistance or find a kind person who can help you. However, relying on them isn’t always practical for maintaining or repairing your vehicle, especially if you find yourself stuck on the side of the road with no one around.
Fortunately, many manufacturers now offer portable jump starters. These are essentially portable power banks, storing energy to boost your vehicle’s battery in an emergency without the need for another car’s help. Many feature lightweight and compact designs that are perfect for keeping in your car, while others are big and bulky, with more robust features like built-in air compressors, USB charging, and even wall-style AC outlets.

The best portable jump starter for your needs is one that has both a peak and sustained amperage output that is suitable for your vehicle. Smaller cars, light pickup trucks, and things like ATVs don’t need as much power as a diesel engine pickup or semi. For typical drivers, a jump starter with a peak output between 1000 and 1400 amps should be more than enough power. But if you have a fleet of commercial vehicles, construction equipment, or even marine vehicles, you’ll want something with an output of up to 6000 amps.

Aside from price, there were several other factors I considered when comparing portable jump starters for this list.
- Size: Not every car or garage has the space to store large, bulky portable jump starters or battery chargers. I made sure to include compact models as well as larger ones.
- Power output: Not all portable jump starters are created equal. If you have a large truck or commercial vehicle, you’ll need a jump starter with a higher amperage output than one you would use on your grandma’s ancient Crown Victoria. Conversely, if you drive an ultra-compact car or have small engine equipment like ATVs, you’ll need something with a weaker output so you don’t burn up your battery or alternator.
- Multiple uses and other features: Several brands like Stanley and DeWalt make portable jump starters that also act as tire inflators, power banks for charging devices, radios, and even flashlights. I made sure to include a few of these for anyone who doesn’t like the idea of a single-purpose device.

While testing and researching each portable jump starter on this list, I kept these criteria in mind:
- Multifunctionality: Nobody has the space or patience to maintain an arsenal of special tools and devices for their vehicle. So I made sure that each model on this list offered at least one other function, be it an air compressor, power bank, or built-in flashlight.
- Vehicle compatibility: No two people are going to drive the exact same car, or have the same power needs for all of their vehicles. Each model on this list has been verified for use in both gas and diesel vehicles as well as marine batteries and ATVs.
- Portability: The whole point of having a portable jump starter is to be able to take it with you, whether that’s on a cross-country road trip or a jaunt across town to the grocery store. While each model may differ in size, each one featured on this list has been vetted for in-vehicle storage.

A jump starter is a piece of equipment that is meant to give a short, powerful burst of energy to your battery in order to get the engine to turn over. After your battery is successfully jump started, you should let your car run for at least 30 minutes so the alternator can recharge the battery.
A battery charger, however, is designed to deliver a slow, steady, much lower level of energy to safely recharge a battery from depletion or to perform regular battery conditioning for peak performance.

Alternators are pretty resilient pieces of equipment, and are built to be resistant to all kinds of outside influences. However, you can severely damage it when trying to jump start your car if you have the cables connected to the wrong battery nodes or if you have the incorrect battery type. Always make sure your cables are connected correctly and that the battery is the correct size and power for your vehicle.

Absolutely. Batteries, including car and truck batteries, aren’t meant to hold a charge forever. And factors such as time, temperature, and even how often you use your vehicle can affect how the battery discharges. If a battery sits for years or experiences extreme temperatures, the battery will slowly discharge energy, which can lead to it not holding enough of a charge to even be jump started. If this happens, the only option is to replace the battery with a brand new one. Fortunately, many places offer discounts for bringing in old batteries or recycling programs to keep dangerous chemicals from leaking batteries out of landfills.
