10 Best Portable Jump Packs 2026 in the United States

The NOCO Boost Plus GB40 is a portable jump pack designed to jump-start dead car batteries efficiently. Its 1000-amp peak current makes it suitable for gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters. One of its standout features is its ability to deliver up to 20 jump starts on a single charge, which is impressive for its compact size and lightweight design at just 2.5 lbs. This makes it very portable and convenient to carry around in your vehicle.

The safety features are robust, including spark-proof technology and reverse polarity protection, ensuring safe use even for those not technically inclined. Additionally, it serves multiple functions as it can act as a power bank to recharge USB devices and includes a 100-lumen LED flashlight with several modes, including SOS and emergency strobe. These extra functionalities add to its value, making it more than just a jump starter. The device is also water-resistant (IP65 rating) and has a rugged, over-molded casing to prevent damage, which enhances its durability.

One potential downside is the recharge time, which is about 3 hours via a USB-C port at 2.1 amps, which might be slower compared to other products in the market. Additionally, while the product has a strong performance for most users, those with larger engines or who need frequent use might find the 1000-amp peak current limiting. However, its high customer ratings and extensive safety features make it a reliable choice for regular users in need of a portable jump pack. The included accessories, such as heavy-duty booster clamps and a microfiber storage bag, along with a 1-year warranty, further cement its practicality and user-friendly design.

The NOCO Boost X GBX155 is a powerful and versatile portable jump starter designed for a wide range of vehicles, including those with large engines. With an impressive 4250 peak amps, this jump starter can handle up to 10.0-liter gas and 8.0-liter diesel engines, making it suitable for cars, trucks, motorcycles, boats, and more. One of its standout features is the extremely fast recharge time, thanks to USB-C technology, fully recharging in just 2.7 hours or providing enough power to jump-start in just 5 minutes of charging. This makes it highly convenient for emergency situations.

Additionally, it doubles as a power bank capable of charging various USB-C devices, such as phones, tablets, and laptops, with 60-watt power delivery. The UltraSafe 2.0 technology enhances safety with spark-proof and reverse polarity protection, ensuring a user-friendly experience. Weighing 7.01 pounds and with dimensions of 8.18 x 4.84 x 13.51 inches, it is relatively portable, though a bit on the heavier side for some users. It also comes with heavy-duty jumper cables, a USB-C charging cable, a 12V fast charger, and a microfiber storage bag. However, some users might find the weight and size slightly cumbersome for carrying around. The built-in 500-lumen LED flashlight with SOS mode is a handy addition for nighttime or emergency use.

One point to consider is the relatively high price, which might be a deterrent for budget-conscious buyers. The NOCO Boost X GBX155 is a robust, feature-packed jump starter that excels in power and versatility, making it an excellent choice for those needing reliable vehicle starting and device charging capabilities.

The WOLFBOX 4000A jump starter is a strong choice for those needing a reliable and portable power boost for 12V vehicles, including cars, trucks, and boats with engines up to 10 liters (gasoline or diesel). Its 24000mAh battery and impressive 4000A peak current give it plenty of power to handle emergency starts, making it suitable for a variety of vehicle sizes. The device is quite portable at just under 3 pounds and slim dimensions, which helps if you plan to carry it in your car or take it on camping trips. One standout feature is the fast recharge time—thanks to a 65W USB-C quick charge, it fully recharges in about 1.3 hours, much faster than many competitors.

The HD LCD display is helpful for checking the device's status at a glance, and the one-touch boost function simplifies jump-starting for users who may not be familiar with the process. Safety is well-covered, with UL, FCC, CE certifications and an IP64 rating, meaning it can withstand dust and water spray, plus it’s tested for operation in very cold or hot temperatures. Added extras like the multifunction LED flashlight (with SOS and strobe modes) add emergency value.

While it’s powerful and portable, the jump starter is specifically limited to engines under 10 liters, so it may not suit very large diesel trucks or commercial vehicles. Also, users should be mindful of the weight if they want a truly compact device for casual use. The included warranty and customer support provide peace of mind. This jump starter is a solid pick for drivers who want a fast-charging, feature-rich, and dependable emergency power pack without complicated setup.
