Key Features:

3000A Peak Current for 10.0L Gas and 8.0L Diesel Engines
The LIFMOCER GS300 delivers a powerful 3000A peak current that jump-starts vehicles in just 1 to 2 seconds, providing professional-grade performance for a wide range of vehicles including cars, trucks, SUVs, motorcycles, and boats. The impressive engine compatibility covers up to 10.0L gas engines and up to 8.0L diesel engines on 12V systems, making this one of the most capable portable jump starters available for both personal and commercial vehicle use. Whether you're dealing with a dead battery on a compact car or a heavy-duty diesel truck, the GS300 delivers the power needed to get your engine running quickly and reliably in any roadside emergency situation.

Force Start (BOOST) Mode for Critically Dead Batteries
The GS300 features a Force Start BOOST mode that can safely restart engines even when the battery voltage has dropped below 2V, a level at which most standard jump starters fail to function. This critical capability makes the GS300 effective in the most extreme emergency situations, including batteries that have been completely drained by harsh winter weather, extended periods of non-use, or accidental light drain. The BOOST function provides the extra surge of power needed to overcome severely depleted batteries, ensuring your vehicle starts every time regardless of how dead the battery may be, giving you complete confidence in any emergency scenario.

LCD Display for Real-Time Battery Monitoring
The built-in LCD screen displays the remaining battery percentage of the jump starter at a glance, allowing you to monitor the power level and ensure the unit is sufficiently charged before you need it. Knowing the exact battery percentage eliminates the uncertainty of wondering whether your jump starter has enough charge for an emergency, allowing you to recharge it proactively when needed. The clear LCD display is easy to read in various lighting conditions, providing reliable power status information whether you're checking it in a bright parking lot or a dimly lit garage.

Multi-Function: Power Bank and 3-Mode LED Flashlight
Beyond jump-starting, the GS300 serves as a portable power bank that charges smartphones, tablets, and other USB devices, making it a genuinely useful everyday carry item rather than a single-purpose emergency tool. The built-in LED flashlight supports three modes including steady light, SOS signal, and strobe, providing versatile illumination for night emergencies, roadside breakdowns, camping, and night travel. The combination of jump starter, power bank, and flashlight in a single compact unit makes the GS300 an all-in-one emergency preparedness tool that earns its place in every vehicle's emergency kit.

10 Intelligent Safety Protections
The GS300 is equipped with 10 comprehensive intelligent safety protections that ensure safe, reliable operation in every use scenario: overcurrent protection, reverse polarity protection, overcharge protection, overdischarge protection, high temperature protection, reverse connection protection, overvoltage protection, overload protection, short circuit protection, and sparkproof technology. The heavy-duty jumper cables are designed to handle the high current demands of jump-starting safely and reliably. This multi-layered safety system protects both the jump starter and your vehicle's electrical system from damage, giving you complete confidence to use the GS300 without risk of injury or equipment damage.

Premium Grade-A Chip with 2-Year Warranty
Powered by a premium Grade-A chip, the GS300 delivers stable performance, fast charging, and professional-level safety that holds up through years of demanding use. The high-quality chip ensures consistent power output and reliable performance in high-demand situations, from extreme cold to high-temperature environments. The GS300 comes with a 2-year warranty and 24/7 customer support, providing peace of mind and long-term protection for your investment.
