Performance

Jump-Starting Power

The most important aspect of any jump starter is its ability to deliver power when needed most. The NOCO Boost X GBX155 excels in this area, providing a whopping 4,250 amps of peak output. This power allows it to start engines as large as 10.0L gas or 8.0L diesel, which is more than enough to handle even the largest trucks or agricultural equipment. Many customers have reported successfully starting their vehicles with ease, even after long periods of inactivity.

For instance, a user mentioned that the GBX155 started their 500-horsepower tractor, an engine that would typically require a larger, industrial-grade jump starter. This speaks volumes about the jump starter’s power and versatility. However, it’s important to note that while the GBX155 can handle a wide range of vehicles, the performance can vary depending on the condition of your battery and the vehicle itself.

Recharging Speed

When it comes to recharging, the GBX155 offers rapid turnaround. With its USB-C Power Delivery feature, the jump starter fully recharges in just 2.7 hours, a speed that is highly competitive compared to other models on the market. If you’re in a hurry, you can gain enough power for a jump start in just 5 minutes, making it ideal for situations where you don’t have time for a full recharge.

Portability

Despite its immense power, the GBX155 is surprisingly compact and easy to transport. Weighing just 7.01 pounds, it fits comfortably in most vehicle compartments, including gloveboxes and under seats. The included microfiber storage bag helps keep it organized and protected when not in use.

Power Bank Capabilities

As a bonus, the GBX155 doubles as a power bank, allowing you to charge various devices like smartphones, tablets, and even laptops via the 60-watt USB-C port. While it may not fully charge a laptop from 0%, it’s more than capable of providing a quick top-up when you need it most. This makes the GBX155 an excellent all-in-one tool for road trips, camping, and other off-grid activities.

LED Flashlight

The integrated 500-lumen LED flashlight is another standout feature. It’s bright enough to illuminate a work area or assist with roadside repairs. The flashlight includes seven different modes, which adds versatility, especially in emergencies. The SOS and strobe modes are useful for signaling for help in case of an emergency, providing an extra layer of safety.
