🚗 Powerful 4000A Peak Jump Starter
The GS4000 can jump start up to 12.0L gas and 10.0L diesel engines in as little as 1–2 seconds, making it ideal for full-size trucks, SUVs, RVs, motorcycles, boats, ATVs, and more.
⚡ Jump Start Dead Batteries (Even Below 2V!)
If your battery is extremely low, just press the BOOST button — it can revive engines even when voltage drops under 2V, something many jump starters can’t do.
📟 HD LCD Display
No more guessing. The bright LCD screen shows battery level, status indicators, and warnings clearly, even in daylight.
🛡️ 10-Level Intelligent Safety Protection
Includes short-circuit, reverse polarity, overcharge, overheat, spark-proof protection and more. Heavy-duty clamps ensure strong and safe conductivity.
🔌 USB Quick Charging + Portable Power Bank
The built-in USB port lets you fast-charge phones, tablets, and other devices on the go.
