This jump starter pack for diesel includes cables, manual, and starter itself. The manufacturer even included a connector to the cigarette lighter, which should be plugged in DC output. Everything is well-packaged. When you take this device in your hand, the first thing that strikes your eyes is an LSD display which shows the voltage. And next to it, you can find a power button.
On one side, there are input to charge the jumper up and DC output. On another side, on the front, 2 connectors to charge your phone took their place. The device is supplied with a flashlight that has 3 modes.

Sounds fantastic, isn’t it?
It comes in a little case with the jumper cable wires and the USB charge cable, book with instructions, and jump starter itself.
The jump starter is very convenient to use, having 4 lights. All 4 lights flashing mean that the battery is at full power. On the front side of it, you have a flashlight and 2 out port charge cables. One is a smart cable, another one is capable of 5V/2.1A. On the same side, there are ports for the cables to jumpstart a car. The inbuilt flashlight comes onboard, as well.

I’m totally sure that this power station can’t be left without attention since it deals with plenty of different tasks and comes at a reasonable price. The GB70 is the one best jump boxes for diesel, a tire, and air mattress inflator, and an effective power station. In an emergency situation on the road or when you want to charge your smartphone quickly, the NOCO makes it best to satisfy your needs.
Besides the device itself, you get a series of different cables: charge cable, as well as a cable to plug other 12-volt accessories to run off the jump pack. And you get a carrying case to put it all in.
This is a 2000 Amp battery, it’s rated for gas engines up to 8L and a diesel engine up to 6L. On the side here, you have 2 separate ports in and out. This has a 2.1 amp USB out and 12V/ 15A out. Also, the user gets a 2.1 amp micro USB in and 12-volt/3A in for a fast charge.

- It works really well. It managed to jumpstart 10 cars without having to charge it.
- Flashlight on the end is much bigger than average flashlights on other jumpstarters.
- It is really safe. So in case you accidentally mix up the cables the warning flashlight will light up.
- It is slow to recharge when you plug it directly into the wall with a micro USB. It may take a full day.
- Cables could be longer. They are only about 10 inches.
This jump starter for a diesel truck can also be called a portable battery charger. Being supplied with a 2000 Amp Peak, 2100 mAh, this 12V power bank can serve up to 8L gas and diesel engines. It also provides a 10W wireless charging.

As well the all Naoko units, this one has reverse polarity and spark protection. It means that if you mix cables, for instance, it will not turn on or if you have 2 volts it will automatically turn itself off. If you don’t have 2 volts, you should push a red button on the front panel, to override it. The white light means that you have enough power even if you can a fully discharged battery.
You can charge a device via a cigarette lighter. To find a necessary port, just take a look at one side of the device where you will find 12V USB out, and 12V USB in. It takes 2-3 hours to be charged this way.

How does a Diesel Jump Starter Work?
The battery jump box for diesel and gas allows starting the engine without having to use another vehicle to give you some boost. Basically, it’s a charging device that jump starts the vehicle by giving it enough current. One of the greatest things about these units is that they help the battery start charging right away. When you hook up the clamps to the battery’s terminals, it transfers its peak amperage to the vehicle’s battery, boosting its cranking amps.
Note that even the best jump starter for diesel only gives out a base peak amperage, so it’s not capable of charging the battery, and it doesn’t matter how long you keep it plugged. It also may not be helpful if your battery is dead or very low on charge. It works by giving you one shot of starting the battery.
Nowadays, many diesel jump starters come supplied with an air compressor and a couple of USB ports. This way, they can also work as the air pumps for tires and the charging units for portable devices (phones, tablets, etc.).
Difference Between Diesel Jump Starter & Gas Jump Starter
The diesel engines need much higher cranking current than their gas analogs of the same size: for example, a four-cylinder gas engine requires 150-200A, while a four-cylinder diesel engine will need 300-400A. So, when opting for a jump starter for a diesel/gas engine, you need to take into account the size of the device: the jump starter for a diesel engine is bigger than the ones that work for gas engines, and, accordingly, are more powerful. The gas engines can actually be charged up even with a very weak jump starter. Though, today’s market can offer the jump-starting units that work for both diesel and gas engines.
How to Jump Start a Diesel
Follow the next steps to jump start a diesel-powered vehicle:
- Read the owner’s manual, provided by the manufacturer of your jump-starting device. In the case, if your vehicle has a positive ground, the instructions on how to use it will be different.
- Check if the starter is charged at full or at least a half.
- Ensure that your vehicle’s battery voltage matches the jump starter’s output voltage.
- Turn your vehicle off and take the keys out of the ignition.
- Turn the jump-starting device off as well.
- Identify the positive (may be marked with such symbols as “P,” “POS,” or “+”) and the negative (may be marked with such symbols as “N,” “NEG,” or “-“) terminals on the battery.
- Identify the positive/negative clamps on the jump starter. As usual, the positive ones are red and the negative ones are black.
- Hook up the jumper cables to the corresponding terminals. Don’t forget to check if the clamps are solidly fixed so they didn’t get loose.
- Turn the jump starter on.
- Wait for at least 30 seconds before starting the vehicle.
- Don’t crank the engine for too long: do this for no more than 5 seconds. If the vehicle won’t turn on after the first attempt, wait for at least 2 minutes before trying again.
- Turn the jump starter off and remove the clamps after the engine starts.
- Allow the vehicle to idle for 3-5 minutes before driving.
Difference between Cranking and Peak Amp
The peak amps are the indicator of the jump starter’s performance. More precisely, it’s the highest current that the unit pushes out during an initial burst when starting the engine. It’s an electrical current that causes the engine to rotate. However, this current fades pretty quickly.
The more stable current is called cranking current, and it gives a more prolonged engine cranking. This way, the cranking current is a more precise measure of the true abilities of the jump-starting device. In most cases, the peak current is sufficient to start the engine before the device’s output power fades out. However, there are also cases when even the cranking current is not sufficient to help you start the engine.
How to Jump Start a Diesel Truck with 2 Batteries
In fact, the process of running the vehicles with 2 batteries is about the same as with a single battery car. The only thing that should be noted if you want to know how to jumpstart a diesel truck is that one of the batteries may have thicker cables. In this way, you should connect the starter terminals to the battery using thicker cables. If both batteries have the same thickness of cable, you can use either one of them.
