Unleashing the Power of NOCO Boost Max GBX155

The NOCO Boost Max GBX155 is the pinnacle of the NOCO X Series, representing a complete reimagining of what a portable lithium jump starter can achieve. Designed for high-displacement gasoline and diesel engines, this unit delivers a staggering 4250 amps of starting power. This is sufficient to jump-start engines up to 10.0L Gas and 8.0L Diesel, covering everything from passenger cars to semi-trucks and motorhomes. The GBX series introduces the new "Extreme" design, which focuses on rapid power delivery and ultra-fast charging. By utilizing the latest lithium-polymer battery chemistry, NOCO has managed to create a device that is significantly more powerful than its predecessors while maintaining a portable form factor that can be handled by a single individual.

Thermal Efficiency and Ultra-Fast Charging

One of the most impressive technical advancements in the GBX155 is its 60W USB-C Power Delivery system. This allows the unit to be fully recharged in just a few hours, or to provide enough power for a jump start after only five minutes of charging. The internal battery architecture is optimized for high-speed thermal dissipation, allowing for multiple jump-starts in quick succession without the unit entering a thermal lockout. This efficiency is vital for roadside assistance professionals who may have to assist multiple stranded motorists in a single shift. The unit also serves as a high-speed charger for USB devices, making it an excellent companion for off-grid travel.

Safety First with UltraSafe 2.0 Technology

Safety is the most critical aspect of any high-power electrical device, and NOCO’s UltraSafe 2.0 technology provides the ultimate peace of mind. This system includes spark-proof technology and reverse polarity protection, but it goes further by improving the thermal efficiency and battery management to provide better performance and longer battery life. The jumper cables are integrated directly into the housing to minimize resistance and heat, and the clamps are designed to be slim yet incredibly durable, fitting into tight battery compartments that other jump packs cannot reach. This ensures a safe, spark-free connection every time, regardless of the user's technical skill level.

A Versatile Tool for Modern Roadside Recovery

The NOCO GBX155 is more than just a battery booster; it is a full-featured emergency tool. It features an incredibly bright 500-lumen LED flashlight with seven different modes, including SOS and emergency strobe. This is an essential safety feature for changing tires or inspecting an engine at night. The ruggedized casing is rated IP65 for water and dust resistance, meaning it can be used in rain, snow, and mud without fear of damaging the internal electronics. This durability makes it a favorite among off-road enthusiasts and heavy equipment operators who work in the most challenging environments on earth.

Unmatched Capability and Safety Features

  • Delivers 4250 amps of peak starting power for engines up to 10L Gas / 8L Diesel.
  • 60W USB-C Power Delivery for ultra-fast recharging and laptop power.
  • UltraSafe 2.0 technology provides spark-proof and reverse polarity protection.
  • High-intensity 500-lumen LED flashlight with multiple emergency modes.
  • Rugged, water-resistant IP65 rated housing for use in all weather conditions.

Advanced Battery Management Systems

The GBX155 utilizes a sophisticated internal battery management system (BMS) that monitors the state of health of each individual lithium cell. This ensures the cells are balanced during charging and discharging, which significantly extends the overall lifespan of the device. The BMS also protects against over-charging and deep-discharging, two of the most common causes of lithium battery failure. By maintaining the battery in its optimal state, NOCO ensures that the GBX155 will be ready to perform even after months of storage. This reliability is why the Boost Max series is considered the gold standard for portable jump-starting technology.

Meh
Size: 10, Color: Black
I had a real leather version of these shoes for many years. They are still totally wearable, however the soles have worn smooth from using them so much. so naturally I buy a new pair. These are the same design. the stitching is close, the pattern in the leather is the same. But they are so much cheaper. There is no real leather. It's all synthetic. The sole is not the same quality of rubber. The stitching is not as good. They look fine, brand new, yet I am sure they will not last. these are cheap. They also cost less, so I guess they are an average value, but I am very annoyed.
