The NOCO GBX155 BOOST X is one of the most flexible lithium jump starters that has ever been produced. This jump starter has a voltage of 12 volts and may be used to jump start a wide variety of vehicles, such as automobiles, motorbikes, trucks, vans, boats, tractors, ATVs, and more. It can start engines with a capacity of up to 10 liters of gasoline or 8 liters of diesel. In this article we are going to explore the difference between the NOCO Boost X GBX155 and the GooLoo GT4000.
Comparison With The GooLoo GT4000 Jump Starter
This portable lithium car battery jump-starter releases maximum energy at every start. This is not an upgrade; rather, it is part of an entirely new series called the Extreme Series. The all-new design of the NOCO Boost X GBX155 features extreme jump-starting power for powerful engine starts. Rated at 4250 amps, this jump-starter for a car battery is made of lithium and is portable.
The Gooloo GT4000 design features an LCD monitor and a 100W charging connector, making it more user-friendly than the product it competes with. This booster’s operation is controlled by an artificial intelligence software, which also provides protection against a wide variety of mistake types and ensures that automatic replies are provided. When working in the dark or in an emergency, the 400 Lumen LED comes in very handy as a source of illumination.

Booster Recharge
When compared to the NOCO GBX155, the GT4000 has an extremely significant advantage in terms of the battery’s ability to be recharged.
The NOCO GBX155 Boost X comes equipped with USB-C technology, which, when combined with power delivery, enables you to achieve lightning-fast recharges. It takes only 2.7 hours to completely recharge, and it only takes 5 minutes to go from having no charge to being able to start the vehicle using the jump starter.
The GT4000 can be swiftly recharged, and it takes a shorter amount of time to bring its battery level back up to full. This effectiveness can be attributed to the 100W charging connector, which enables the device to reach its maximum capacity in just approximately one and a half hours of charging. If you charge the jump starter for three minutes after it has been totally discharged, it will be able to hold enough energy to jump-start a vehicle.
Supported Batteries
The Gooloo GT4000 has a higher capacity for charging mobile devices. It can be used to power up electric appliances that make use of 12V units, as well as jump-start the batteries of vehicles with 12V engines.
You have the ability to charge virtually anything with the assistance of the NOCO GBX155 USB-C Power Delivery. Its built-in power bank delivers a total of 60 watts of power, which can be drawn either in or out, making it easy to charge all of your favorite USB-C devices, including smartphones, tablets, laptops, and wearable electronics, among other things.
Compatible Vehicles
The GBX155 is one of the most multifunctional lithium jump starters that have ever been created. All types of vehicles, including automobiles, motorbikes, trucks, all-terrain vehicles (ATVs), boats, recreational vehicles (RVs), sport utility vehicles (SUVs), tractors, and more with gasoline/ petrol engines of up to 10 liters and diesel engines of up to 8 liters can be jumped started. With a maximum starting power of 4250 amps.
GT4000 demonstrates compatibility with gas engines with a modest capacity. It is only capable of starting gasoline/ petrol engines that have a capacity of up to 12 liters, despite the fact that it is compatible with diesel-powered or hybrid engines that have the same 10-liter capacity.
Unique Features of GT4000
Even though the NOCO GBX155 Boost X is significantly more advanced than the GT4000 in a number of respects, the GT4000 retains a few characteristics that are exclusive to itself. For example the method for pre-heating the environment. After connecting the vehicle’s battery, the GT4000 can operate in temperatures as low as -40 degrees Celsius and reach the required temperature for starting within one minute.
After connecting the jump starter to the vehicle battery or pushing the BOOST button for one to two seconds in extremely cold environments, the pre-heating feature will start up on its own, regardless of whether you did it manually or automatically.
On the LED screen that is 3.2 inches in size, all of the information concerning the current status of the product is shown in a clear and understandable manner. There are ten different types of protective technology that are built in, and they work together to alleviate any concerns you may have regarding faulty functioning or sparks.

Fast Charging
The Gooloo GT4000 is recharged using either the car charger that is supplied or a quick-speed wall charger (Quick Speed Wall Charger not Included). The 100W max input function can only be reached by using this device in conjunction with a PD100W USB-C wall charger or a SC100W vehicle charger. The PD100W USB-C quick speed wall charger is not included in the kit and must be purchased separately. It can be found here.
The GBX155 features rapid charging technology that enables it to be charged at a rate of up to 60 watts per minute when the device is connected to an external power source. In order to make full use of this function, you will need a charger that is compatible with your device and is capable of providing 60W of power via USB-C Power Delivery 3.0. When the charging rate is greater than 15 watts, the “rapid charge” LED will light up to indicate that USB Power Delivery 3.0 is in operation.
How to Charge GBX155
The GBX155 needs to have a full charge applied before it can be used because it only has a half charge when it’s first removed from the packaging. Connect the GBX155 to the computer using the USB-C IN/OUT connection by making use of the USB-C Charge Cable that is provided in the package or the 12V Car Charger. It is possible to recharge it using any powered USB port, such as an AC adapter, car charger, laptop, or any of a number of other options.
The USB-C IN/OUT port makes use of Power Delivery 3.0 technology, which makes it capable of receiving or sending up to 60W. The amount of time required to recharge a GBX155 will vary depending on the level of discharge it has experienced as well as the type of power source that is being utilized. Depending on the state of the battery, the actual results can be different.
When the internal battery is being recharged, the GBX155 has charge LEDs which indicate the level of charge the battery has. The LEDs will slowly pulse ‘on’ and ‘off’ before becoming solid until all four charge LEDs are on. After the battery has been fully charged, the green LED that indicates 100% charge will remain lit, but the LEDs that indicate 25%, 50%, and 75% charge will become “off.” The maintenance charge indicator, a green LED that flashes 100% of the time, will do so at irregular intervals.
Jump Starting with GBX155
- Before attempting to jump start the vehicle, make sure that all of the power loads in the vehicle, such as the headlights, radio, and air conditioning, are switched off.
- To begin the jump-starting process, press the power button, and you will notice that all of the LEDs will flash once. When you are linked to the battery in the correct manner, the white boost LED will light up, and the battery charge LEDs will flash in sequence. As soon as a battery is recognized, the start of a countdown for a timeout that lasts sixty seconds will occur.
- Try turn the engine over and see if it will start. The vast majority of cars and trucks can be started instantly. If you try to start the vehicle and it does not do so immediately, wait 20 to 30 seconds and then try starting it again. In order to begin a new jump-start process after the 60-second timeout has elapsed, the device will need to be powered off and then back on again. Within a period of fifteen minutes, you should not attempt more than five consecutive jump starts at a time. Wait fifteen (15) minutes after the GBX155 has been allowed to rest before attempting to jump start the car once more.
- After you have started your vehicle, turn off the device, release the battery clamps, and remove the GBX155 from your vehicle.
Final Reflections
Both of the jump starts that have been discussed above come with their own set of advantages and disadvantages. However, the NOCO Boost X GBX 155 is currently in the lead since it delivers an easy user experience and is of a very high quality.
