The build quality of the GBX155 is exceptional, with a tough, rubberized casing designed to withstand rough handling and environmental exposure. It feels solid and well-made, offering a sense of durability that’s perfect for both everyday and emergency use.
Design & Features:
- Massive Power: With a 4250A peak current, this is one of the most powerful jump starters in its class. It’s designed for heavy-duty vehicles like trucks, RVs, boats, and large diesel engines. The 10.0L gas and 8.0L diesel engine compatibility make it an excellent choice for anyone with a larger vehicle or a fleet that needs a reliable jump starter.

It includes reverse polarity protection, spark-proof technology, and overcharge protection, ensuring that it’s incredibly safe to use. Even if you accidentally connect the clamps incorrectly, it won’t damage the device or your vehicle’s electrical system.
- LCD Display: The LCD screen on the GBX155 provides real-time information, including the remaining charge and the status of the jump-start process. It’s clear and easy to read, which is especially helpful in low-light or emergency situations.
- Multi-functional: The NOCO Boost X GBX155 is more than just a jump starter; it doubles as a power bank with a USB output for charging phones, tablets, and other devices on the go.

The GBX155 detected the battery’s status and provided just the right amount of power to get the engine cranked up fast.

If you’re ever unsure about the status of your jump-start, the display screen clearly shows the progress, so you’re always in control. Even if you’ve never used a jump starter before, the GBX155 makes the process straightforward and stress-free.
Portability & Storage:
Despite its power, the GBX155 is reasonably compact for its capabilities, weighing about 10 pounds.
