GT4000 vs GT4000S: Which 4000A Jump Starter Is Right for You?
Comparing the GOOLOO GT4000 and GT4000S? Both deliver 4000 peak amps, support a wide range of 12V vehicles, and provide powerful portable charging. The key difference is cold-weather performance.
Quick Answer
Choose the GT4000 if you regularly drive in extremely cold conditions. Its Intelligent Pre-Heating Technology is designed to help start vehicles in temperatures as low as -40°F. If you want a powerful everyday jump starter with a broad operating temperature range, the GT4000S is an excellent alternative. Both models provide 4000 peak amps, support 12V vehicles, and feature a large 88.8Wh battery with PD100W USB-C charging.
A dead car battery can leave you stranded at home, in a parking lot, or far from roadside assistance. A reliable portable jump starter provides a convenient way to get back on the road without depending on another vehicle.
The GOOLOO GT4000 Jump Starter and GOOLOO GT4000S Jump Starter are two high-output options designed for drivers who want substantial starting power in a portable package.
So, what is the difference between the GT4000 and GT4000S? Let's compare their key features and find out which model may be better suited to your driving conditions.
Power and Vehicle Compatibility
Both the GT4000 and GT4000S deliver up to 4000 peak cranking amps. This gives either model the power needed for a wide range of 12V vehicles, including cars, motorcycles, ATVs, RVs, tractors, boats, and lawn equipment.
Depending on the vehicle and battery condition, both models are designed to support vehicles with gas engines up to 12.0L and diesel engines up to 10.0L.
Battery Capacity and Charging
Both jump starters use an 88.8Wh / 24,000mAh battery based on a 3.7V cell rating. The large battery capacity provides enough portable energy for vehicle starting as well as charging personal devices.
One of the standout features shared by the GT4000 and GT4000S is PD100W USB-C input and output. This allows compatible devices to charge much faster than with conventional USB charging.
Each model also includes two USB output ports and one 15V DC output port, giving you several options for powering or charging compatible electronics and accessories.
Cold-Weather Performance
Cold weather is where the GT4000 and GT4000S differ most significantly. Low temperatures can reduce battery performance and make engine starting more difficult, particularly during winter or in extremely cold climates.
GT4000: Built for Extreme Cold
The GT4000 features GOOLOO's Intelligent Pre-Heating Technology, designed to help the jump starter operate in temperatures as low as -40°F. The pre-heating system helps prepare the battery for starting without requiring a long waiting period.
GT4000S: A Broad Operating Range
The GT4000S is designed to perform across a wide temperature range of approximately -4°F to 140°F. For everyday driving and normal seasonal conditions, this provides substantial temperature coverage.
Display and Operation
Both models feature a 3.2-inch LCD display that makes important information easy to monitor during use.
The display provides useful information such as battery level, operating status, and error reminders. This helps you understand the jump starter's condition before and during a jump-starting session.
Built-in LED Light
Vehicle emergencies do not always happen during daylight. Both the GT4000 and GT4000S include a built-in 400-lumen LED light for situations where additional illumination is needed.
The light includes flashlight, strobe, and SOS modes. You can use the flashlight to inspect the engine bay, illuminate an area around the vehicle, or use the SOS mode to signal for assistance in an emergency.
Safety Features
Jump starting involves high electrical current, so built-in protection is an important part of choosing a portable jump starter.
Both models incorporate multiple protection systems designed to help provide safer operation, including:
- Over-current protection
- Overload protection
- Over-voltage protection
- Overcharge protection
- Additional protection through the smart jumper cable system
The included smart clips and jumper cables help monitor the connection between the jump starter and vehicle battery, adding another layer of protection during use.
