Heavy Duty Jump Starters That Actually Start Big Engines
For most heavy duty needs, the NOCO Boost Plus GB40 is the top pick. It delivers 1000 peak amps and is compact enough to store in a glovebox. Its main advantage is its safe spark-proof technology and ease of use. The main limitation is that it is not for the largest diesel engines; for those, consider the GB150.

Good to know
How many times can I jump start my truck on a single charge?
It depends on the battery capacity of the jump starter and the size of your engine. For example, the NOCO GB40 can provide up to 20 jump starts on a single charge for a standard car, but fewer for a larger truck. High capacity models like the Schumacher SJ1332 with 18Ah can do more, but it is recommended to recharge after a few uses.
Can these jump starters be used on diesel engines?
Yes, most models are rated for diesel engines, but the peak amp requirement is higher. For small diesel engines (up to 3 liters), the NOCO GB40 is sufficient. For larger diesel engines, you need at least 2000 to 4000 peak amps. Always check the manufacturer’s specifications for engine size limits.
Are these jump starters safe for my vehicle’s electronics?
Yes, quality jump starters come with safety features like spark-proof technology, reverse polarity protection, and overcurrent protection. These prevent damage to your vehicle’s computer systems. Always follow the instructions and connect the clamps correctly.
How long does it take to recharge the jump starter itself?
Recharge times vary by model. Most can be recharged from a wall outlet in 2 to 4 hours. Some also support recharging from a car’s 12V outlet, but that takes longer. The GOOLOO GP4000, for instance, has a fast charge feature that can reduce charging time.
Can I use these to charge my phone or other devices?
Yes, most jump starters have USB output ports to charge smartphones, tablets, and other small electronics. Some also have a 12V output for accessories. However, using the jump starter for charging will reduce its available power for jump starting.
What is the difference between peak amps and cranking amps?
Peak amps is the maximum current the jump starter can deliver in a short burst. Cranking amps is a measure used for batteries to indicate the current they can provide at 32°F (0°C). For jump starters, peak amps is the relevant spec. Higher peak amps generally means more starting power.
How do I maintain my jump starter?
Keep it charged. Lithium batteries slowly discharge over time, so recharge it every 3 to 6 months. Store it in a cool, dry place. Avoid extreme temperatures. Clean the clamps periodically to ensure good contact. Follow the manufacturer’s instructions for storage.
Can I jump start a vehicle with a completely dead battery?
Yes, most models can handle a completely dead battery as long as the battery is not damaged. Some have a ‘force’ mode to bypass protection when the voltage is very low. Always read the manual. For example, the NOCO Boost series has a manual override feature.
Our pick
For most drivers with heavy duty trucks, the NOCO Boost Plus GB40 is the best balance of power, portability, and safety. If you own a large diesel truck or frequently face extreme cold, the GOOLOO GP4000 offers the most power for the price. Choose the Schumacher SJ1332 if you also need an air compressor for off-road use. Avoid low amp models if you have a big diesel engine.
