Both the Noco GB150 and the GBx 155 are powerful jumpstarters. These Noco jumpers are well-suited for heavier vehicle batteries that need massive current influx to restart. Besides that, compact dimensions, USB ports and built-in torches turn these products from just jumpers to multi-functional tools.
GB150 (Boost Pro) is modishly designed jump starter that comes with integrated voltage indicator and pre-attached jumper cables. With different types of input and output ports it is easier to use and also offers the facility to power up 12V electronics on the go.
Conversely, GBX155 (Boost X) characterizes a similar look but has larger charge storing capacity. Thus, it can be used for even larger engine batteries very conveniently. Its advanced protective technology and increased thermal efficiency makes jumping more efficient and safer.
Compared with GB150, GBX155 is a lightweight jumper with high-power internal unit and enhanced safety features. It also has a higher peak current level and is useful for heavier engines but it is comparatively expensive.

Design
Comparatively speaking, GBX155 is relatively lightweight and has different in/out ports than the competitor. It has a USB-C in/out and two USB-A outputs but does not have any DC port or micro-USB port. Its unique design elements are its various LED indicators (charging level, fast-charging, reverse polarity, connectivity error, heat, cold and boost function).
Conversely, input ports of GB150 are very different including a 12 VDC fast charging inlet and a micro-USB input. Due to this feature, its adapters and connector cables are different as well. Plus, a voltmeter is integrated in this starter that tells the exact voltage level of the exhausted battery. It also weighs a little heavier than the competitor.
These starters resemble with each other for rest of features like flash intensity, temperature endurance and physical dimensions, showing a grey-black design. Their buttons and LED indicators are present on the upper side of the starter while ports and flashlight are located on the sidewalls. They also have a highly luminous flashlight whose various modes (SOS, Blink, Emergency, 10%, 50%, 100% brightness) make the starter an efficient camping torch as well. Similarly, both these jumpers require same temperature conditions for storage, charging and operation.

Recharging
Both these starters specify a fast recharge feature but through different charging sockets. GB150 has a 12V DC input that provides fast charging when connected with 5A (60W) charger. Besides that, this device has a micro-USB input that works with adapters up to 2.1A capacity. However, this port does slower charging than the other input. XGC adapters are included in the package for easy connections.
On the other side, GBX155 does not have a DC charging port and only enables charging via its USB-C in/out port. However, this port specifies 60W charging ability, enabling you to recharge the starter completely within 2.7 hours. However, fast charging is only possible when you use a compatible 5A (60W) charger. If you use a low-power charger, it would take several hours to replenish the storage level as its battery units have vast charge-holding capacity. Charge cables are provided with the package.
| Charger | GB 150 | GBX 155 |
| 5W | 45 h | 32 h |
| 10W | 22 h | 16 h |
| 60W | 2 to 3 h | 2.7 h |

Peak Starting Current`
GBX155 is a comparatively powerful jump starter as it offers high peak current that can be used to restart huge-sized batteries. The credit goes to its internal unit that has a higher charge storing capacity compared to its competitor. The electric power of its battery cell reaches up to 99 watt per hour, enabling it to provide the huge influx of 4250 ampere to bring life to a dead engine unit.
In contrast, GB 150 can store lesser charge and thus, its peak influx is also lower. Therefore, it is utilized to jump start small sized batteries in comparison. Its internal battery specifies 88 Wh electrical energy which limit its maximum discharge capacity to 3000 Amperes.

| Battery capacity | 88 watt-hour | 99 watt-hour |
| Peak current rating | 3000 Amperes | 4250 Amperes |
Safety system
These starters are equipped with an anti-spark system and also employ mechanisms to regulate charge-discharge functions within a safe range. However, GB150 specifies an earlier and relatively less advanced safety structure (named UltraSafe technology) from Noco. This includes reverse polarity protection and spark-proof features to ensure a safer jumping operation.
In contrast, GBX155 is constructed using UltraSafe 2.0 technology, which is an upgraded version of the competitor’s safety structure. Resultantly, this starter has higher thermal efficiency and provides better safety from overheat damages. Its power management is also enhanced and charge storage and supply is better regulated.
Manual Override
These starters do not supply heavy current when attached to totally exhausted batteries because sudden high influx gives rise to many safety concerns. Thus, spark-proof system of these GB starters automatically stops the discharge in such cases. GB150 stop detecting batteries when voltage is below 2 volts but GBX 155 stops supplying current at 3 volts due to its superlative protection mechanism.
However, you can manually bypass security systems if your battery has very low voltage and does not restart with normal jump starts. Press the boost button on top of the device to override over-discharge protection and supply heavy current to your engine battery.
Supported battery types and Vehicles
Noco specifies these starters only for jumping and recharging 12V lead-acid batteries. Thus, these tools work well lead-acid batteries having wet, gel, MF, EFB or AGM cells. But using them with other battery types or voltage levels may lead to accidents.
As for vehicle compatibility, Boost X takes the lead over the contestant by supporting relatively heavy duty vehicle batteries. It can jump start batteries employed in 10L gas or up to 8L diesel engines. However, this jumper cannot be used to power 12V accessories as it lacks a DC output port.
On the other side, GB150 is compatible with smaller engines in comparison as its charging cell is relatively less powerful. But it is effective for supplying power to 12V electronic appliances like tire inflator, or small fans etc.
