Best Jump Starters for Diesel Engines 2024 – What You Need to Know?
Keeping a jump starter in your vehicle is always recommended since you never know when the battery could cause trouble on the road. The traditional cables are convenient.
All you need to do is to connect a dead battery to a well-working one. However, the problem is when there is no one around. For example, when your car dies in the middle of nowhere.
In that case, a much better solution is a portable car jump. It’s no surprise that this is one of the main trends when it comes to additional things to always carry in your trunk.
Let’s see what are the best models for diesel engines in 2024.
1. S ZEVZO ET5000
| Peak Current | 8000 Amps |
| Battery Capacity | 27,000mAh |
| Engine Compatibility | All gas engines and up to 16.0L diesel engines |
| USB-C Fast Charging | 60W PD, recharges in 2 hours |

If you are looking for a reliable product, the S Zevzo is one to go with, and make your trip safer and hassle-free.
I tested it on my 7.3L diesel truck, which normally takes a significant amount of effort to jump-start. To my surprise, this compact jump starter fired up my truck in under 30 seconds.
With 8000A peak current, this jump starter can handle even the toughest jobs, starting engines up to 16.0L diesel or any gas engine without breaking a sweat.
Also, thanks to the 60W USB-C fast charging, you can fully recharge the jump starter in only 2 hours.

Another excellent choice comes from Clarke. It provides impressive power with a peak current of 1200A. While it may not offer the same capabilities as the previous model, it’s still perfect for most diesel engines today.
Moreover, the Clarke JSM 1200 is compact and light. It won’t take up any space in your trunk. You can even keep it under the seat(but don’t forget that you placed it there).
When it comes to potential downsides, I read some of the comments about overheating. If you have a diesel car or a truck with more than 3 liters, it simply won’t be efficient enough.
3. Gooloo GP4000 Portable
| Feature | Details |
| Battery Capacity | 26,800mAh |
| Peak Amperage | 4,000A |
| Max Diesel Engine Capacity | Up to 10.0 liters |
| Ports | 2 USB, USB-C, 12V outlet |
| LED Light | Yes (with strobe and SOS modes) |
Unlike the previous cable, the Gooloo portable jumper offers much higher flexibility. Not just for regular cards, but also for trucks and heavy machinery with engines up to 10 liters.
Furthermore, you will enjoy the advantage of having a battery capacity of over 26,000 mAhs, which means that you keep it in your trunk for a long time without recharging.
The only downside is the weight and size. It could take some space in the trunk, which can be frustrating if you have a smaller vehicle.
4. Halo Bolt Ai
| Weight | 2.5 lbs |
| Dimensions | 3.82 x 7.17 x 1.6 inches |
| Amperage | 500A |
| Air Compressor | Yes (Integrated) |
| USB Ports | Yes (multiple) |
| Flood Lamp | Yes |
Don’t let it’s size fool you. This compact device can jump-start most cars on the roads today. The limit is 3.0 liters.
The convenience is especially seen when you realize that you can keep it in the glovebox. There is also an integrated air compressor, which can help you with inflated tires, or when you want to clean your car.
Still, I must highlight that it is not a suitable buy if you own a truck or a car with bigger engine.
5. Stanley J5C09

| Weight | 17.8 lbs |
| Dimensions | 11 x 7.5 x 13 inches |
| Peak Amperage | 1,000A |
| Max Diesel Engine Size | Up to 6.5 liters |
| Air Compressor | Yes (120 PSI) |
| Work Light | Yes (bright, swivelable) |
| Power Station Capabilities | Yes (USB and 12V car plug ports) |
Another great portable jumper comes from Stanley, a well-known brand in the car market. The best part about this model is that you can use it on all regular vehicles today (the limit for diesel engines is 6.5 liters).
It also has an air compression feature, meaning you can also use it for an inflated tire, or any other situation that requires air compression.
When it comes to cons, I can only mention its size. it is indeed quite bulky. If you own a regular sedan or a smaller diesel with an engine of up to 2 liters, maybe some lighter option will be more suitable.
