GOOLOO GP3000 3000A Lithium Jump Starter — Compact 12V Jump Box for 9L Gas / 7L Diesel with BOOST and 400-Lumen LED

GOOLOO GP3000 is a compact 3000-amp lithium jump starter designed to restart 12V vehicles up to 9L gasoline or 7L diesel engines while also powering devices and roadside tools.

The GP3000 combines high cranking power, multi-layer safety, and practical emergency features into a portable jump box. Built with GOOLOO JUMPCORE and SUPERSAFE technologies, it’s engineered to revive deeply discharged batteries, protect users from common electrical hazards, and provide useful auxiliary power on trips, work sites, or during roadside incidents.

How reliable is the GP3000 at actually starting large engines?

The GP3000 delivers up to 3000 peak amps and is rated to start most 12V vehicles, including gas engines up to 9 liters and diesel engines up to 7 liters. A BOOST mode helps when the vehicle battery is completely depleted or has too low a voltage to detect.

• 3000 amps peak cranking power for heavy-duty starts
• Suitable for cars, trucks, SUVs, ATVs, yachts, and more
• BOOST button for deeply discharged batteries
• Works reliably across a wide temperature range (-4°F to 140°F)

What safety features protect me and my vehicle?

GOOLOO equipped the GP3000 with its SUPERSAFE protection suite to minimize electrical and user risks. The included smart jumper cable and internal circuitry guard against reverse polarity, sparks, overload, and other common dangers.

• 10-layer protections: over-charge, over-current, short-circuit, reverse-polarity, and more
• All-metal heavy-duty clamps resist wear and maintain a safe connection
• Spark-proof design and reverse-charge prevention for user safety
• Built to operate safely in extreme temperatures

What extra functions does the GP3000 offer besides jump starting?

Beyond starting a vehicle, the GP3000 acts as a multi-tool battery pack for emergencies and roadside needs. It integrates charging ports, a bright LED, and a DC output to run common car accessories.

• Two USB outputs for phones, tablets, and accessories
• 400-lumen LED flashlight for night-time assistance or signaling
• 15V DC output to power tire inflators, vacuums, and similar devices
• Compact design with included storage case and charging cables

How durable and serviceable is the unit for regular use?

The GP3000’s hardened, scratch-resistant shell and premium components are designed to withstand the bumps and drops of field use. Regular maintenance is simple: keep it charged every few months to preserve battery health.

• Rugged plastic housing resists impact and surface wear
• Recommended recharge interval roughly every 3 months
• Includes smart jumper cable and multiple charging cables in box
• Compact, portable footprint for storage in trunks or work kits

Who is this for? The GOOLOO GP3000 is aimed at drivers, fleet operators, outdoor enthusiasts, and tradespeople who need a dependable, all-in-one power and jump-start solution. It’s especially useful for owners of large gasoline or diesel vehicles, those who travel in remote areas, or anyone who wants a robust emergency power kit that doubles as a device charger and roadside tool power source.
