Portable jump starter and power bank

The GOOLOO GP4000 delivers 4000A peak current to start all gasoline engines and diesel engines up to 10.0L displacement. Its 24000mAh capacity also serves as a portable charger for phones, tablets, cameras and other USB devices via dual ports, one supporting QC3.0 fast charging. The unit includes a 15V/10A DC output for 12V accessories such as tire inflators or car refrigerators.

Sustained operation across temperature extremes

Rated to function from -4°F to 104°F, the GP4000 maintains starting capability and device charging in harsh outdoor conditions. A full recharge via the Type-C input completes within 8 hours, and the internal battery holds standby power for 3-6 months between uses. The smart jumper cables incorporate eight protection circuits covering overcurrent, overload, overvoltage and overcharge scenarios during repeated jump-start cycles.

Rugged enclosure with integrated lighting

The waterproof and stain-resistant housing protects internal components during adventure, travel or emergency use. All-metal clamps on the smart cables resist breakage from long-term handling. A built-in LED work light offers three modes — solid, strobe and SOS — for visibility and signalling in low-light situations. The kit bag stores the jump starter, cables, wall charger, USB to Type-C cable, Type-C to Type-C cable and cigarette lighter adapter together.

Questions about this item

Does the 4000A peak current generate noticeable heat or noise during extended use?

The unit has no moving parts, so it runs silently; heat build-up is minimal during the short cranking bursts for which the 4000A rating applies.

What must I already own to recharge the GP4000 from empty?

A standard wall socket for the included Quick Charge wall charger, or a USB-C power source; the Type-C port reaches full charge in about 8 hours.

Will the 15V/10A DC output safely run my older 12V tire inflator and car fridge?

Yes, the 15V/10A(max) DC port is designed for 12V accessories such as tire inflators and portable fridges, and the smart jumper cable adds eight protection circuits.
