other benefits from this jump starter

This is one of the best purchases I have ever made because additional to all the benefits and advantages this product has, the additional convenience is that you get to help other people needing a jump start without having to risk your own car battery.

Few people know that using the normal jumper cables to pass current to other car can damage your own car battery and compromise its performance or active life.

Yet at the same time it is hard to not help other person with their car if we can help, especially if they are at the middle of nowhere.

The Noco GB40 jump starter solves both issues in one shot, and it does it efficiently and quickly.

Our Rating

The Noco Boost Plus jump starter combines the reliability and performance of a high price jumper pack with the compact design and simplicity if much more affordable boosters.

It really delivers since it is a product made by a company that backs it up with over 100 years of experience in the business, and the best is you can check the comments and opinions of current users to validate the claims of this product.

Yet nothing like seeing the GB40 Boost Plus 1000A in action and witness the simplicity of its operation as well as its power. Take a look at these videos with Noco GB40 reviews and you’ll see how easy is using and charging this lithium jump starter.


Noco has different lines of products and the GB40 is under the NocoBoost umbrella. Here you have all the models available in that family so you can compare them.

Honestly, unless you have a big diesel truck, the Noco Boost Plus is the one you need. The GB20 as well may seem like a good option but consider this won’t start big gas cars like 8-cylinder Silverados or Rams.

This thing is amazing, never again jump a car the old conventional way sitting there revving up the engine. This thing doesn’t matter even if…


I used this product one time without incident. Recharged it properly and stored it in a hard Noco case that I bought to replace the cheap sock style…


I was skeptical of these contraptions but no longer. The first car I tried with it though it acted like it wasn’t working (at all). Fortunately I had read the…

how to use the gb40 noco

If you check the Noco’s website they say using their booster is pretty simple, and in deed it is. Yet it is until you use it and read the manual that some important details come to light.

Here I want to share with you what I’ve been able to find by using this booster for the last year and a half.

it truly is very simple to use

90% of the times you need to jumpstart a car battery you’ll just have to plug the clamps to the battery terminals, turn on the booster, wait for the charge LEDs to describe a follow pattern, start your engine, turn off the booster, unplug the clamps and that’s it!

what to do when it is not that simple (it happens…)

The other 10% may offer additional challenges and here I want to discuss them.

Manual Override

There will be days when you’ll need to use the manual override or boost mode function with flat dead batteries. Before doing this, make sure the connection is right, that is, red clamp to positive and black clamp to negative terminal.

Under normal conditions, the Noco battery charger GB40 will detect a reversed connection, yet if the battery is heavily discharged, the manual override function is the way to go.

The manual override disables the safety features of the Noco 40, so it won’t detect a reversed connection and if the connection is not right, this could damage your car’s electronics. To avoid this, always double check your connection to ensure it is not reversed.

Faulty engine

Another thing that happened to me was that my car’s engine was faulty but I was not aware of it, so I assumed that the battery was drained because of something and that a jump start would fix everyhing.

My Noco GB40 gave me 3 consecutive attempts to jump start my car, all 3 in less than 30 seconds. This got the internal battery of the jumper hot and the high temperature protection of the booster kicked in.

After maybe 20 minutes (hot summer day) I was able to try it for another 3 times until the booster showed empty.

My car did not start and I thought the GB40 had failed. It was until later that I discovered a failure in the engine that was preventing the car to start, so this really depends on your car’s engine condition as well.

other things to know Before buying it

No wall charger included: Inside the box you’ll find a micro USB cable that connects to a Type-A USB charging brick, but this brick is not included.

No type-C USB port: Other models from Noco and other brands come with a USB-C port but not this one.

3 Hrs. to fully charge: Since no USB-C input is available, the charging time of this unit is 3 hours, which is longer than other similar models from competing brands.


This is a wonderful product that keeps you from worrying about dead batteries. It’s one of those products you should keep in your vehicle at all times.

It’s portable and easy to use and comes with some of the most advanced safety features making it one of the best jump starters you can buy.

FAqS from the community

can you use the noco boost gb40 to jump start a 4.5l diesel engine?

You can definitely try. While Noco does advertise this booster for only 3.0L diesel engines, sometimes people report they are able to jump start bigger vehicles with it.

There is a technical support to this.

Theoretically speaking, you need 1 amp per in³ (cubic inch) of your gas engine and double of this for diesel cars.

Assuming your engine, oil, and the ambient temperature are OK, a 4.5L Diesel engine amps requirement to start is as follows.

1L = 62 in³
4.5L x 62 in³ x 2 (diesel engine requirement) = 558 amps

This means that 558 amps are enough to jump start your 4.5L diesel engine, if everything else is right. That is, the condition of the motor, the motor oil and the ambient temperature are OK.

Since the GB40 delivers up to 1000 amps, you can definitely give it a shot.

Remember that the amps act like that lever that will rotate the engine. If the engine is rusty or the oil is not liquid but most solid, it would be harder to spin the wheel.

The same is true if the ambient temperature is too low, since the freezing temperatures tend to make it difficult for the motor gears to spin.

Is there any care or maintenance THE jump starter needs?

Nothing special. Store this product in a dry and cool place because humidity and hot environments can damage it severely.

Before getting into your vehicle to go for a long drive, check the charge of this product. You can use your vehicle’s power or any wall outlet to charge this device and it can hold it for up to 12 months.

Is there a warranty for this product?

It comes with a one-year official warranty and you can also return this product within one month of receiving it.

Will this unit start my V8 Ford Mustang?

Yes. It can start up to 6.0L gas engines and a V8 Ford Mustang is not as big, so it should be able to start it.

How long will it hold its juice to give me a jump start when I need it? How often should I recharge it?

12 months. Yet you can charge it every 6 months to ensure its battery is in optimal conditions.

About its lifespan, it really depends on how often you use it, but if this is for personal use only, it can be years before you need to replace it.

Do I need to remove the clamps quickly after jumping the battery to avoid damaging other electronics?

No. Thanks to its UltraSafe technology you don’t need to hurry in doing that.

Is it good for Gel batteries?

Yes. It starts any Lead-Acid battery, including Gel ones.

Can I use it as a car battery charger?

No. This is not a charger but a jump starter box. It will not charge nor maintain your battery but only give it that initial spark so the engine starts running. The alternator should do the charging part.

Will it work on my Ford Escape?


Does the unit go connected to a power source to jump start a car?

No. This jumper box uses an internal Lithium battery to pass current to your car’s battery and start the engine. Just need the Lithium battery to be charged and that’s it.

How many times can I charge my iPhone with this unit?

Only 2. If you mean from 0 to 100% charge, then 2. If your phone is somewhat charged and you want it to fully charge it, you can have more times of that. It also depends on how big the battery of your iPhone is.

How is it can jump start a car several times but small electronics like phones only a couple?

Some small electronics have very large batteries and they consume lots of power. If you talk about charging a phone from 0 to 100%, a unit like this can only charge these a few times.

Jump starting a car requires much less charge because most car’s batteries have some charge in them, so this unit only provides what is missing to start the engine.

How long are the cables?

About 12 inches from the connector to the clamps tip. These are long enough to reach any battery terminals.

Can I get only the replacement cables?

Yes. You can get them here.

The Noco Plus is not working, what can I do?

Probably need to be more specific about what “not working” means. You can check the user guide on this page and go to the troubleshooting section to find more help.

What does the red light indicates?

This is the error LED and if it is on means you have a wrong connection like a reversed polarity or the connection with the battery is not good. Make sure you are connecting the clamps to the right poles of the battery.

what is the noco boost plus charge time?

The GB40, also known mistakenly as the Noco Boost Sport GB40, does not come with a wall charger. It depends on what you use to charge it, but if you charge it from a normal USB port, the Noco Boost Plus GB40 charge time is anything between 3 to 6 hours.

how much it costs?

The Noco boost plus GB40 price is No products found.. Sometimes it is lower depending on if there is a special offer. We’ll always have the best deal here for you available, so be sure to check our page regularly.
