10 Best Portable Battery Jump Starters 2025 in the United States

The NOCO Boost Plus GB40 is a portable battery jump starter that boasts a powerful 1000-amp lithium battery, capable of jump-starting gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters. This makes it a reliable option for most standard vehicles. With a battery capacity that allows up to 20 jump starts on a single charge, it ensures you have ample power when needed. The safety features are particularly impressive, including spark-proof technology and reverse polarity protection, which prevent accidents and make the device user-friendly even for novices.

Weighing just 2.5 lbs and compactly designed, it's quite portable and easy to store in your vehicle. The multipurpose nature, functioning as a power bank for USB devices and featuring a 100-lumen LED flashlight with multiple modes, adds to its versatility. The rugged, water-resistant design (IP65 rating) enhances its durability, making it suitable for various environmental conditions.

However, some potential drawbacks include the relatively short 24-inch cable length, which might limit flexibility in certain situations. Also, while it charges quickly (around 3 hours), it requires a powered USB-C port, which could be a minor inconvenience if you don’t have one readily available. Despite these minor issues, the NOCO Boost Plus GB40 stands out for its robust performance, advanced safety features, and multi-functionality, making it a solid choice for anyone looking for a reliable portable battery jump starter.

The NOCO Boost X GBX155 is a powerful and versatile portable battery jump starter, ideal for those who need a reliable solution for jump-starting large engines. With a peak output of 4250 amps, it can efficiently jump start vehicles with up to 10.0-liter gas or 8.0-liter diesel engines, making it suitable for cars, trucks, boats, RVs, and more. Its robust battery capacity also allows it to function as a 60-watt USB-C power bank, enabling you to charge a range of devices like phones, tablets, and laptops on the go.

One standout feature is its rapid recharge capability; it can go from zero to ready for a jump start in just 5 minutes of charging, thanks to the USB-C technology with power delivery. Safety is well-addressed with UltraSafe 2.0 technology, which includes spark-proof and reverse polarity protection, enhancing user confidence and reducing the risk of mishaps. This model is also designed for enhanced thermal efficiency and power management, contributing to a longer battery life.

On the portability front, it weighs in at 7.01 pounds and has compact dimensions, making it relatively easy to carry and store, although it might feel slightly heavy for some users. Additional features include a 500-lumen LED flashlight with SOS mode, providing extra utility in emergency situations. The product comes with heavy-duty jumper cables, a USB-C charging cable, and a 12V USB-C fast charger, packed in a microfiber storage bag. While the price point might be higher than some competitors, the combination of power, safety features, and versatility makes the NOCO Boost X GBX155 a strong contender for those needing a reliable and multi-functional jump starter.

The AstroAI S8 Car Battery Jump Starter is a compact and lightweight device designed to jump-start vehicles with up to 6.0L gas or 3.0L diesel engines, making it suitable for most cars, SUVs, motorcycles, and small trucks. Its 1500-amp peak current means it can quickly start dead batteries, which is a strong point for emergency use. The built-in smart boost mode helps with very low battery voltages, increasing its reliability when a battery is fully drained. The jump starter also includes metal clamps designed to prevent heat damage and ensure a better connection, adding to its safety features. In fact, the device protects against many common risks like reverse polarity, overcurrent, and short circuits, which makes it user-friendly and safe even for those new to jump starters.

Portability is another big plus here—at less than 1 pound and roughly the size of a small book, it fits easily in a glove box or travel bag. Beyond jump-starting, it doubles as a power bank for charging devices and includes a versatile LED flashlight with multiple modes, which can be handy in roadside emergencies. However, its 37Wh battery capacity is moderate, so it won’t provide many jump starts before needing a recharge, especially in cold weather where performance can drop. Also, while it’s durable for everyday use, it’s not heavy-duty enough for larger trucks or continuous professional use.

This jump starter is an excellent choice for everyday drivers who want a reliable, easy-to-carry, and safe solution for unexpected dead batteries, with the bonus of extra practical features for trips and emergencies.
