GOOLOO GT6000 Jump Starter (JS-271)

Which GOOLOO this is: GT6000, model JS-271

The listing names the GOOLOO GT6000 but gives JS-271 as its model and part number. GOOLOO's own GT6000 manual, linked from the GT6000 product page, prints GT6000 on its cover together with Model No.: JS-271. GOOLOO's GT4000S manual cover prints the same Model No.: JS-271, so the code alone does not single out the GT6000; check that the listing title still says GT6000 and 6000A before you order. The manual names Shenzhen Carku Technology Co., Ltd as manufacturer.

Because the listing uses JS-271 rather than the GT6000 name in its model field, check that any manual, charger or spare part you buy later names the GT6000 and not only the code. GOOLOO also sells the GT6000 in bundles with chargers, inflators and storage boxes, and this listing's bullets list the jump starter with a 100W car charger, cables and a storage bag.

The 6000-amp rating and two capacity figures

GOOLOO's page and manual give 6000A peak current for all 12V gasoline engines and diesel engines up to 12.0L, and the manual's specification table adds a starting current of 800A. The manual says the unit is for vehicles with 12V batteries only and says to start a vehicle only when the pack shows more than 20 percent.

Capacity is stated two ways. GOOLOO's page and the listing describe a 27,000mAh battery, while the manual's specification table gives 99.9Wh, 6750mAh at 14.8V. The manual also gives a life of more than 1000 cycles, and GOOLOO's page claims a 24-month standby.

GOOLOO's page gives the GT6000 as 8.98 by 1.49 by 3.92 inches and 4.44 pounds, and lists a 10-layer protection system covering reverse polarity, overcurrent, over-temperature, short-circuit and over-voltage and under-voltage.

Outputs, the display and the flashlight

The manual lists a USB-C port for input and output at up to 100W, a USB-A QC3.0 port at up to 18W, a second USB-A port at 5V 2.4A and a 15V 10A DC output rated at 150W maximum. It says the DC port is an output for car products and not a charging port, and that a cigarette lighter socket adapter is included for it.

The 3.2-inch display shows battery percentage, charging power, low-current mode, reversed clamps, a battery low temperature reminder and a READY signal, per the manual. GOOLOO's page adds pre-heating status to its readout list without describing that function elsewhere, so ask GOOLOO before relying on it.

The manual describes the LED light's modes as Normal, Strobe and SOS, GOOLOO's page calls them Bright Light, Strobe and SOS, and the manual's highlights page and the listing name a 400-lumen light with SOS, Spotlight and Strobe.

Charging: 1.4 hours needs a charger that is not in the box

The manual's specification table gives a full charge time of about 1.4 hours with a quick-speed PD100W wall charger, and says the unit reaches its 100W input only through a PD100W USB-C wall charger or the included SC100W car charger. It says the wall charger is not included and must be bought separately.

The manual's package list is the unit, a carrying bag, a USB-A to USB-C cable, a USB-C to USB-C cable, the jumper cable, the SC100W car charger, the cigarette lighter socket adapter and the user manual. It says charging other devices works while the unit charges, but not while it is starting a vehicle.

GOOLOO's FAQ says the unit turns itself off after 30 seconds without use, that it has a minimum load current of 200mA, and that Low Current Mode is for small devices such as earbuds and smartwatches. It says to recharge the pack every 3 months.

Temperature limits, IP65 and starting limits

The manual and GOOLOO's FAQ give an operating range of -20 to 60 degrees Celsius (-4 to 140 F) and warn against storing the pack in a vehicle parked in hot weather for long periods. The manual says to charge only at -10 to 45 degrees Celsius (14 to 113 F), and its error table asks you to restore the unit to 32 to 113 F when it reports a temperature fault.

GOOLOO calls the GT6000 IP65 water resistant; the manual says it handles small splashes but must not be immersed in water. The manual says not to start a vehicle more than 4 times within 10 minutes, and its error table says the unit enters a safe mode for 10 minutes if you do. The starting steps and full warnings are in the manual; read them before first use.

Warranty: 18 months in the manual, up to 30 on the website

The manual's warranty section lists 18 months of online after-sales service, a 30-day money back guarantee through Amazon, and replacement of a unit that fails from manufacturing issues within 18 months. It asks the original purchaser to show the original receipt or order ID, and excludes normal wear and tear, physical abuse, improper installation, misuse, modification and unauthorized third-party repairs.

GOOLOO's product page advertises up to 30 months of warranty without saying on that page what extends it beyond the manual's 18 months. Ask GOOLOO which term applies to an Amazon purchase before relying on the longer figure; the manual lists 1-888-886-1805 and fiona@gooloo.com for US support.
