10 Best Jump Starters For Diesel Trucks 2025 in the United States

The NOCO Boost Plus GB40 is a compact jump starter that's particularly appealing for those with diesel engines, providing 1000 peak amps and suitable for vehicles with up to 3.0-liter diesel engines. One of its standout features is its ability to perform up to 20 jump starts on a single charge, making it a reliable companion for heavy-duty use. The lightweight design (just 2.5 lbs) and small size make it highly portable, fitting easily in a truck or storage compartment.

Safety is a notable strength with the GB40. Its UltraSafe technology helps prevent incorrect connections with features like spark-proof technology and reverse polarity protection, making it user-friendly even for those who may not be mechanically inclined. Additionally, the device doubles as a power bank for charging USB devices and includes a bright LED flashlight with multiple modes, which can come in handy during emergencies.

There are a few drawbacks to consider. While it's effective for smaller diesel engines, its peak output may not be sufficient for larger or more powerful diesel engines, which could limit its usability for some truck owners. The battery capacity, while decent, might not offer the same extensive usage as some larger, bulkier jump starters, which could be a concern for those who need heavy-duty performance. Durability is generally good, with an IP65 rating for water resistance and a rugged build, but the plastic construction may not withstand extreme conditions as well as metal counterparts. The NOCO Boost Plus GB40 is an excellent choice for casual to moderate use, providing ample power and safety features for most diesel trucks, but those with larger engines or looking for extreme durability might need to explore other options.

The WOLFBOX 4000A Jump Starter is a powerful tool with a 24000mAh battery capacity and an impressive peak output of 4000 amps, making it highly suitable for starting large diesel and gasoline engines up to 10 liters. Its robust cranking and peak amps ensure it can restore power in emergency situations for a variety of vehicles, from cars to boats. The device is quite portable, weighing only 2.9 pounds and being compact in size, which makes it easy to store and carry around.

The HD LCD display is a practical addition, providing clear information about the device's status and functions, which helps users operate it easily. Its 65W USB-C quick charging capability is a significant advantage, allowing it to charge fully in just 1.3 hours and also power other electronic devices like phones and laptops, making it very versatile for travel or camping needs. The booster and LED flashlight with multiple modes (SOS, strobe, high-beam) are handy for emergency situations, adding to its utility.

On the safety front, it excels with IP64 protection against harsh conditions and 10 different safety features, including spark-proof and temperature protections, ensuring safe usage. Some users might find the price point higher compared to basic models, and its advanced features might be more than what a casual user needs. Additionally, while the compact size is generally an advantage, it could be seen as less rugged and durable than bulkier models designed for heavy-duty use. Still, for those needing a reliable and feature-rich jump starter, the WOLFBOX 4000A offers a balanced mix of power, portability, and safety.

The S ZEVZO ET03 jump starter is a strong choice for diesel truck owners and those with large gas engines, thanks to its high peak current of 2500 amps. This level of power means it can jump-start engines up to 7.0L diesel and 8.0L gas, which covers many trucks and larger vehicles. It’s compact and lightweight at just 1.4 pounds and small dimensions, making it easy to carry or store in your vehicle. The 74Wh battery capacity lets it perform up to 50 jump starts on a full charge, which is quite convenient for multiple uses.

Safety is well-covered here, with 10 intelligent protections that help prevent accidents like short circuits or reverse polarity, and the smart clamps beep and flash if something is wrong. Additional features like two USB ports allow charging your phone or tablets, and a bright 400-lumen LED flashlight with different modes (steady, strobe, SOS) adds practical emergency use. The standby time of over 24 months is impressive, though it’s important to remember to recharge it every few months to keep it ready.

One drawback is that to jump a completely dead battery (0V), the jump starter itself must be fully charged or show above 14V, so you need to keep it charged regularly. Also, while it’s durable enough for regular use, it’s not described as rugged or waterproof, so handle it carefully around harsh weather. This jump starter combines powerful engine support, portability, and useful extras with strong safety features, making it a solid, user-friendly option for diesel truck owners and others needing reliable jump-start assistance.
