10 Best Portable Jump Starter 2026 in the United States

The NOCO Boost Plus GB40 is a portable jump starter that excels in its ability to jump-start both gasoline and diesel engines, making it a reliable choice for car owners. With a peak output of 1000 amps, it can jump-start engines up to 6.0 liters for gasoline and 3.0 liters for diesel, which is quite impressive. The compact design, weighing only 2.5 pounds, enhances its portability, allowing users to easily store it in their vehicles without taking up much space.

One of the standout features is its safety design, which includes reverse polarity protection and spark-proof technology, ensuring that users can jump-start their vehicles without the risk of incorrect connections. This makes it particularly user-friendly for those who may not have experience with jump starters. In addition to jump-starting capabilities, the GB40 doubles as a portable power bank for USB devices and includes a built-in LED flashlight with multiple modes, adding extra utility. The durability is also commendable, with an IP65 rating indicating that it's water-resistant and designed to withstand various weather conditions.

The product has many strengths and does have some limitations. Although it's compact, the size may not suit everyone’s needs, especially if you're looking for something more robust for heavy-duty use. The charging time of 3 hours could also be a downside for those who need a quick turnaround. Additionally, the no-frills design may lack advanced features that some tech-savvy users might desire. The NOCO Boost Plus GB40 is an excellent choice for casual car users seeking a reliable, safe, and portable jump starter with added functionalities, though those needing something heavier may want to consider larger options.

The NOCO Boost X GBX155 is a powerful portable jump starter designed for those who frequently deal with larger vehicles like trucks and SUVs, as it’s capable of starting engines up to 10.0-liters in gasoline and 8.0-liters in diesel. One of its standout features is its impressive peak output of 4250 amps, which means it can jump-start a dead battery quickly and efficiently. Additionally, the USB-C power delivery makes it a multifunctional device, allowing you to charge smartphones, tablets, and even laptops, providing 60-watts of power both ways. The turbo charging capability is also a huge plus, with the device being able to go from 0% to jump-starting in just 5 minutes under certain conditions, and fully recharging in only 2.7 hours.

Safety is a top priority with the Boost X, featuring UltraSafe technology that includes spark-proof design and reverse polarity protection. This helps prevent mishaps during operation, making it easier for less experienced users to handle. Furthermore, the included accessories like heavy-duty jumper cables and a microfiber storage bag enhance its convenience and usability.

On the downside, its weight of 7.01 pounds may be cumbersome for some, especially if portability is a primary concern. While it is designed to be portable, there are lighter options available on the market that might be more suitable for users who prioritize weight over power. Additionally, the higher price point may deter some potential buyers who are looking for more budget-friendly alternatives.
