GOOLOO GT4000S Jump Starter Key Features & Specs

The GOOLOO GT4000S Jump Starter is packed with features that make it a standout product in its category. Understanding these specifications helps in appreciating its robust performance and versatility.

4000 Amp Peak Current

At the core of the GT4000S’s impressive capability is its 4000 Amp peak current. This immense power allows it to jump start virtually any 12V vehicle on the road, including large diesel trucks up to 10 liters and all gasoline engines.

This level of power significantly surpasses that of many standard jump starters, which often max out at 1000-2000 Amps. The higher amperage provides a more reliable and quicker start, especially for stubborn engines or in extremely cold conditions.

It means you won’t be left stranded by a weak battery, even if you own a heavy-duty vehicle or equipment. The GT4000S provides the necessary punch to get your engine turning over efficiently.

100W Two-Way Fast Charging

The GT4000S is equipped with advanced 100W USB-C Power Delivery (PD) technology for both input and output. This allows for incredibly fast recharging of the jump starter itself, reducing the time it takes to get back to full capacity.

When used with a compatible 100W PD wall charger (sold separately), the unit can be fully recharged in a fraction of the time compared to traditional models. This rapid turnaround is crucial for professionals or those who need constant readiness.

Furthermore, the 100W PD output enables the GT4000S to act as a powerful portable charger for laptops, tablets, smartphones, and other USB-C powered devices. This multi-functional aspect adds immense value, transforming it into an essential emergency power source.

SuperSafe Lithium Technology

Safety is paramount with battery-related devices, and GOOLOO has integrated its SuperSafe technology into the GT4000S. This comprehensive protection system guards against a multitude of potential hazards, ensuring user and vehicle safety.

Key safety features include reverse polarity protection, short-circuit protection, over-current protection, over-charge protection, and over-temperature protection. These safeguards prevent damage from incorrect connections or internal malfunctions.

The intelligent clamps provide visual and audible alerts for incorrect usage, making the jump-starting process foolproof. This level of protection instills confidence, especially for novice users who might be apprehensive about handling vehicle electrics.

Portable & Durable Design

Despite its powerful capabilities, the GT4000S maintains a relatively compact and portable form factor. It’s designed to be easily stored in a trunk, glove compartment, or under a seat, ready for immediate use.

The robust casing is built to withstand the rigors of automotive environments, offering resistance to drops, dust, and splashes. Its durable construction ensures longevity and reliable performance even in challenging conditions.

The package typically includes heavy-duty clamps and a USB-C charging cable, all neatly organized for convenience. The thoughtful design extends to ease of handling and storage, making it a practical tool for any vehicle owner.

Built-in LED Flashlight

An often-overlooked but highly useful feature is the integrated LED flashlight. This powerful light source is essential for nighttime emergencies or working in dimly lit areas under the hood.

The flashlight typically offers multiple modes, including a steady beam, a strobe light for signaling, and an SOS signal. This adds another layer of safety and utility, making it a valuable tool in any roadside emergency kit.

Power Bank Functionality

Beyond its 100W USB-C PD output, the GT4000S also includes standard USB-A ports. This allows it to charge a wider array of devices simultaneously, from older smartphones to action cameras and other gadgets.

Having a reliable power source to keep your communication devices charged during an emergency is invaluable. The GT4000S ensures you stay connected, even when your vehicle’s battery is dead or you’re far from a power outlet.
