What Is The Noco GBX155 Booster?

The NOCO GBX155 is a rugged, portable lithium jump starter designed for 12V/24V vehicles up to 8.0L gasoline or 6.0L diesel engines. It features a waterproof (IP68) and dustproof design, integrated LED flashlight, and USB-C Power Delivery (100W) for charging devices. Built with a 2,000-amp lithium iron phosphate (LiFePO4) battery, it supports up to 60 jumps per charge and includes reverse polarity protection to prevent damage from incorrect clamps.

What defines the NOCO GBX155’s core functionality?

The GBX155 combines high-current jump-starting with multi-device charging, using LiFePO4 chemistry for rapid 3-hour recharges. Its waterproof casing withstands 1m submersion for 30 minutes, while the 400-lumen LED offers SOS/strobe modes for emergencies.

Technically, the GBX155 delivers 2,000 peak amps through brass clamps with 40% less voltage drop than copper alternatives. The proprietary X-STAT voltage stabilization prevents overloading sensitive electronics during jumps. Pro Tip: Store it at 50% charge if unused for months—LiFePO4 cells degrade slower than Li-ion when partially charged. For example, jump-starting a dead 6.7L diesel truck in -20°C requires holding the “Boost” button for 3 seconds to activate cold-weather mode.

How does the GBX155 handle extreme environments?

With an operating range of -40°C to 70°C, the GBX155 uses temperature-compensated charging algorithms. The LiFePO4 cells maintain 80% capacity after 2,000 cycles, outperforming standard Li-ion jump starters (500 cycles).

In desert conditions, the thermal cutoff engages at 75°C, pausing operations until cooling. Conversely, Arctic mode preheats cells using internal resistors when temps drop below -20°C. Pro Tip: Wipe clamps dry after saltwater exposure—chloride corrosion increases resistance by 0.3Ω/cm² annually. A real-world test showed 22 consecutive jumps on a frozen semi-truck battery before needing recharge.

What charging capabilities does the GBX155 offer?

Beyond jump-starting, the GBX155 functions as a 100W power bank, charging laptops via USB-C PD and smartphones with its 15W wireless pad. The input accepts 12-24V DC or USB-C PD for flexibility.

Charging a MacBook Pro from 0-50% takes 45 minutes using the 100W USB-C port. However, simultaneous device charging reduces jump-start capacity by 20%—prioritize vehicle needs first. Pro Tip: Use a GaN charger for fastest wall recharging (3 hours vs. 5.5 hours with 18W adapters).
