GOOLOO Jump Starter GT4000 Arctic — 4000A Peak, -40°F Preheat & PD100W Charging

The GT4000 Arctic jump starter combines high peak current with cold-climate engineering and modern power delivery so you can restart a 12V vehicle quickly, even in subzero conditions. Built for drivers who face extreme temperatures, it pairs heavy-duty starting capability with multiport charging, a bright emergency light, and advanced safety protections. Compact enough to stow in a trunk yet powerful enough for large gas and diesel engines, this unit is designed to reduce wait time and increase confidence during roadside situations.

How does the GT4000 help start a dead battery in freezing weather?

The GT4000 delivers a 4000A peak output and includes a battery pre-heating system that activates at extreme low temperatures. That preheat function raises battery performance so the starter can turn over engines down to -40°F. It also has a BOOST mode for very low-voltage batteries, giving an extra surge when a standard jump may fail.

• 4000A peak current for 12V vehicles up to 12L gas / 10L diesel
• -40°F pre-heat tech preserves ignition ability in severe cold
• BOOST mode for reviving extremely depleted batteries
• Compatible with cars, SUVs, trucks, motorcycles, ATVs

What safety features protect me and my vehicle?

Integrated SuperSafe technology includes a battery management system with multiple protections to minimize risk during use. The smart jumper cable is spark-proof and prevents reverse polarity, while internal safeguards handle short circuits, overcurrent, and overcharge scenarios. These layers let you jump-start without the uncertainty and hazard of traditional cable-to-cable methods.

• Built-in BMS with 10 protections including reverse-polarity prevention
• Spark-proof smart clamps for safer connections
• Overcurrent, short-circuit, and overcharge guards
• Designed for easy one-person operation in roadside conditions

Can it charge devices and how fast does it recharge itself?

Beyond engine starts, the GT4000 functions as a versatile power bank with PD100W USB-C charging and multiple DC/USB outputs for phones, tablets, and laptops. The included 100W car charger refuels the unit from 0–100% in about 1.2 hours; a quick 5-minute top-up can provide enough energy for an emergency start. The fast charging capability makes it useful for work trips, camping, and long drives where device uptime matters.

• PD100W USB-C port suitable for fast laptops and phones
• 150W DC output plus two USB-A ports for multiple devices
• 100W car charger included for ~1.2 hour full recharge
• Quick 5-minute charge yields emergency start capacity

How reliable is the GT4000 for long-term emergency readiness?

The GT4000 is engineered for extended standby and repeated cycles: it can remain on standby for up to 24 months when fully charged, and its cells support over 1,000 charge cycles. Regular six-month top-ups keep it primed for emergencies. An 18-month warranty and a full accessory kit ensure you have everything needed right out of the box.

• Up to 24 months standby life when fully charged
• Over 1,000 charge cycles for long lifespan
• 18-month warranty and included carrying bag and accessories
• Complete kit: smart cables, charging cords, car charger, adapter

Who is this for? The GOOLOO GT4000 Arctic suits drivers who need dependable starting power in harsh climates—commuters, truck owners, fleet vehicles, RV and ATV users, and anyone who values fast device charging and enhanced safety features. If you want a compact, fast-charging jump starter that performs in extreme cold and doubles as a capable power bank, the GT4000 is designed to give practical, long-term readiness on the road.
