ADVANTAGES of the noco gbx 155

You are investing in peace of mind: A dead battery ruins your day. If you get stuck at the middle of nowhere with your family in the car is worse. The GBX 155 saves the day & keeps you and your family going. Worth to mention this booster works as needed when you need it.

Great Benefit vs Cost: The Ultra Safe technology, the reliability of the booster, the power it supplies to your small electronics, the size of engines it effectively jumps, the integrated LED flashlight, the 5 min for a single jump, and the fast charging capability make this jump starter a real bargain for the price you pay and the benefits you get.

4250 Amps: What makes your car start every day are the quantity of amps it gets from the battery. An 8-cylinder gasoline engine of 5.7L requires 300 – 400 amps to start. This booster gives you 10x that power and is designed to work with 10L gas and 8L diesel engines.

Force Start with a Button: If the battery is heavily discharged the force start function pushes power through the battery to start the engine. Again, this function is not available in all jump starters, but the Noco Boost X GBX155 4250A 12V has it. Just remember this mode disables safety features so be careful when using it.

Charge your phone and laptop: The 155 GBX also works as a battery charger for your phone, drones, cameras, laptop, and other small electronics.

USB A&C Ports: This ports help to charge your electronic gadgets and the booster itself. And the USB-C port provides fast charging.

12V Cigarette adapter: Charge your booster on the go with the 12V adapter. Connect it to the cigarette lighter of your car and never run out of battery.

5 min for 1 jumpstart: Other jumpers need to have 50% to 80% of charge to boost your car. The GBX155 only needs 5 minutes of charge to give you one effective jump start and get you back on the road.

Fast charging: This is a game changer for jump starters of this size because other boosters take 7, 8 and even 24 hours to fully charge. The Noco Boost X 155 needs about 4 hours with the included cigarette adapter, and 2.7 hrs with the 60W one (sold separately) to get 100% charge.

Forget about sparks: Sparks are the reason why people (especially women) are afraid to jump start a car. And rightfully so, who wants the risk of an electroshock jumpstarting a car? Now this is past with the Ultra Safe technology the GBX155 has, and yes, even if clamps touch each other when the booster is On.

No more damaged cars due to incorrect clamps connection: Another big risk when jumpstarting a car is damaging its electronics that control the motor, which is not easy nor cheap to fix. The reverse polarity protection of the Noco GBX155 ensures that only until the connection is right the booster will pass power to the battery.

Internal Battery Booster Temperature protection: This is to protect the investment you’ve done with this booster. The GBX155 will tell you if the temperature of its battery is too hot or too cold to operate. Worth to mention that operating a Lithium battery in the wrong temperature may damage the unit, so the booster will protect itself until the temperature is right.

Saves power automatically: If you happen to leave On your jump starter, it will discharge eventually and won’t have power to boost your car when you need it. The auto power conservation mode of the Noco Boost X 4250 amps turns it off after 60 seconds of pushing the On button to ensure the unit is charged when you need it.

Lithium battery: These hold more power in less space than lead-acid batteries and that is what allows them to be very portable. So look for a lithium battery based jump starter if you want a portable and efficient unit.

500 Lumen lamp: This lamp is so bright to help you see in the dark with sharp clarity and do an effective jump start.

HOW TO USE THE gbX155 noco – easy and intuitive

Here some comments you want to remember when using this unit.

• After the clams are connected to the right battery terminal, push the On button.
• You should see a the Charge LEDs chasing and the BOOST LED turning solid white.
• This indicates you can start your car.

Yet if things are not this straight forward, here are some tips about what you can do.

ERROR OR PROTECTION LEDS ARE ON

The image above shows a summary of the potential causes why each LED is on or blinking, yet it is a good idea to check the manual and specification sheet (included after this section) to exactly know what is going on.

Yet most common problem is a reversed connection, so ensure the connection is right and check again.

none of the error leds are on or blinking but can’t jump start the car

This is another typical scenario where the car’s battery is so discharged that the booster does not detect it, and it is very common. For this you’ll have to use the manual override function.

Here is what you have to do:

1. Remember that manual override disables all protections, so if clamps touch each other sparks will be produced and a reversed connection could damage your car.
2. Ensure the clamps are attached correctly, that is, the red to the positive terminal of your battery and the black to the negative one.
3. Press and hold the manual override button❗️for 3 seconds until the chasing pattern appears and the BOOST LED blinks white.
4. Start your car.

After this turn off the booster and disconnect the clamps. Here you have some videos to show you how it’s done.

What You Need to Know Before Buying the gbx 155 jump starter

Manual override disables safety functions: It is important to know that the force start function disables safety features. Right now, there are no alternative products with force start and safety features at the same time, but is good to know before getting this booster.

No wall charger included: The GBX155 does not come with a wall charger. Most customers don’t care because they can charge it from their computer, their car, or using a spare brick charger, but it’s good to know you won’t receive a wall adapter inside the box.
