10 Best Battery Jump Starter 2025 in the United States

The NOCO Boost Plus GB40 is a compact yet powerful battery jump starter designed for both gasoline and diesel engines. With a peak output of 1000 amps, it can jump start most vehicles quickly and efficiently, allowing for up to 20 jump starts on a single charge. This feature is particularly beneficial for drivers who require a reliable backup during emergencies.

One of the standout aspects of the GB40 is its safety features. It incorporates a mistake-proof design, including spark-proof technology and reverse polarity protection, which makes it easy to use, even for those who might be unfamiliar with jump starting a vehicle. This focus on safety is a significant advantage in the battery jump starter category.

In addition to being a jumper, it doubles as a portable power bank, allowing users to charge smartphones and other USB devices. The built-in 100-lumen LED flashlight with multiple modes, including SOS, adds extra functionality, making it a versatile tool for roadside emergencies. Portability is another strong point; the unit is lightweight at just 2.5 pounds and features a rugged, water-resistant design, rated IP65, ensuring durability in various weather conditions. However, while it is compact for a jump starter, some may find it a bit bulkier than simpler models. On the downside, the GB40's battery capacity may not be enough for larger or more demanding vehicles, particularly those with bigger engines outside its stated limits. It's also important to note that while it has a robust build, the price might be on the higher side compared to less feature-rich alternatives.

The GOOLOO GP4000 Jump Starter stands out as an impressive option in the battery jump starter category, particularly for those needing a reliable tool to jumpstart various vehicles. With a peak output of 4000 amps, it can quickly revive all gasoline engines and diesel engines up to 10.0 liters, making it suitable for cars, motorcycles, trucks, and even larger vehicles like RVs and yachts. Its robust battery capacity allows for over 60 jump starts on a single charge, which is quite remarkable for users who might frequently face dead batteries.

Portability is also a strong point here; at just about 4 pounds and with a compact design, you can easily store it in your vehicle without taking up too much space. The inclusion of dual USB ports and a Type-C charging port means you can power your other devices, providing added value beyond just jump-starting. Safety features are well addressed with 10 types of protection to prevent misuse and damage. The all-metal clamps add to the durability of the device, ensuring it can withstand repeated use. However, while the GP4000 is rugged, it would be good to note that it's not fully waterproof, so caution is advised in wet conditions.

Another plus is the built-in flashlight with multiple modes, which can be invaluable during emergencies at night. Plus, it operates effectively in extreme temperatures ranging from -4°F to 140°F, making it a reliable choice for colder climates. In addition, while the product has high performance, the absence of a wall charger in the package might be inconvenient for some users. Overall, the manual could be clearer for those unfamiliar with jump starters, which may require some extra learning for first-time users.
