Will the GT6000 start a large diesel truck?

It is rated at 6000A peak, which Gooloo targets at large gasoline and diesel engines. Peak current is a brief surge, so a deeply discharged or very cold diesel may still need a second attempt or a warm battery.

How long can it sit before I need to recharge it?

Gooloo claims up to 24 months of standby. That assumes moderate storage temperatures and a full charge; check the battery indicator every few months and top it up before long trips.

What can I plug into the 15V/10A DC port?

It powers 12V and 15V accessories such as tire inflators and inverters through the included cigarette lighter adapter. Check the accessory's draw stays within the port's 10A limit.

What comes in the box?

Heavy-duty jumper cables, a 100W car charger, USB-to-USB-C and USB-C-to-USB-C cables, a cigarette lighter adapter, a storage bag and a user manual.

Can it charge a laptop or phone?

The three USB ports handle phones, tablets and other USB devices. There is no AC outlet, so laptops that need mains power are not supported.

How does it compare with smaller GOOLOO jump starters?

Smaller Gooloo models are lighter and cheaper but rated for smaller engines. The GT6000 trades portability for higher output, a larger battery bank and the 15V DC port.

Our take on the GOOLOO 6000A Jump Starter GT6000 Car Starter

The GOOLOO GT6000 is a 6000A peak-current lithium jump box for cars, trucks and other 12V vehicles, built around a 27,000mAh battery. It doubles as a power bank with three USB ports and a 15V/10A DC output for tire inflators and inverters, and it adds a 400-lumen flashlight with spotlight, strobe and SOS modes. Gooloo claims up to 24 months of standby between charges, backed by multiple protection circuits. It suits drivers who want one box for jumping, charging phones and running 12V accessories; it is bulkier and heavier than pocket-sized 1000–2000A jumpers, and its peak rating is a surge figure, not the cranking current a starter sees continuously.
