We also loved the crisp LED display, which allows for a trio of lighting modes, the dual quick charge USB ports and the multiple safety features, including over-charge protection.
Though this jump starter does offer a compact form factor, it is heavier than some other picks on this list, clocking in at nearly four pounds. Additionally, we found that the LED display struggled to adequately illuminate the information in bright sunlight. Compare this with the best remote car starter to be sure the Audew is the best.

On the diesel front, this only supports engines up to 5.5L, so we’d recommend our top pick over this one for diesel drivers. Also, there is no LED display, which can make it tricky to know just how much juice is left in the unit.

The battery on offer, however, is not as powerful as our top picks, though should be able to handle most 12V gas engines. Additionally, it must be charged every 30 days or it will cease to function, so maintenance is a must. To make sure your car stays protected, you’ll want to take a look at the best car alarm too.

Though this jump starter does technically service diesel engines, it only offers support for engines up to 5.5L, which is on the lower side.

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.
Best Portable Jump Starter Buyer’s Guide
The Most Important Features to Consider
- Engine Size Limitations
Most of the above products have some type of limitations as to what size engines they can adequately jump start. Make sure your engine size is supported before making a purchase, though our list does feature a couple of “catch-all” battery packs, like our top pick, which are certified to work with just about any engine out there. These limitations typically only come into play, however, with unusual vehicles, such as large trucks.
- Size and Weight
These are portable jump starters, so you are going to want to make sure they aren’t overly heavy and that they can fit somewhere in the car when not in use. To that end, we placed a spotlight on products as light as a pound or so and several that easily fit into a standard-sized glove box. Even the biggest model on our list, however, can fit in the backseat or in the passenger side floor.
- Safety Features
You are going to want to make sure that the jump starter you choose has a number of built-in safety features to reduce the risk of accidental damage. To that end, most of the above products feature overcharge protection and many have built-in alarms that will alert you if you have attached the clamps incorrectly.
- Additional Features and Accessories
Modern portable jump starters come with an array of additional features and accessories. These include quick charge USB ports, for juicing up smartphones and related gadgets, and DC outlets for the charging of larger items, such as laptops. Most items on our list also come with powerful LED flashlights, often with SOS modes when you are in trouble, and feature built-in compasses and an array of other useful gadgets.
