Review: ممتاز
Review: I bought the GT4000S because I have a Ford Excursion with the large 6.8L Ford that has sit in recent times because of surgeries. I inevitably forgot to unhook the battery and after many weeks of sitting, it runs the battery down. Most recently a door switch began acting poorly and caused the battery to drain quickly. 2 weeks post surgery and the battery read less than 3 volts on a DMM. Tried a traditional pack I have (Stanley MAXX 1000A) and it turned on the lights but never attempted to crank. The GT4000S however, was very easy to set up, with one connection to the unit and essentially two button pushes. Out of the box and to my surprise, it immediately turned over my engine and started my Excursion with little effort. Only took 3% from the batteries charge as well. The display is basic but gives pertinent information. The unit itself is ruggedly built and its features are pronounced. The USB-C connections will charge everything from a laptop to a phone with ease. It will vary the voltage based upon the need of what is being charged. For jump starting, it will not let you hook up the terminals incorrectly and will indicate to you that you have them incorrectly placed. It recharges quickly, but is limited in the USB-C to <50watts when not connected to a dedicated 100watt charger from GOOLOO, which more than doubles the 1.5 hours to over 3 hours from dead, but isn't a huge concern as I plug it in overnight after using it then place it back in my truck in the morning. Overall, I am impressed with this unit and cannot say enough about it. Its compact, comes with a charging cable (USB-C to USB-C) jumper cables, a carry case (nylon type of sack), and a hefty manual. Couple of tips, if it has trouble starting the car because the battery is drained to near zero, press the button once to put it in boost mode, and immediately start the vehicle. Invest in the hard case kit that is sold for them. Well worth it and ensures that screen is 100% protected.

*by K***T on 3 July 2025*

Necessary for any car or RV and roadtrip. Just bought this for our son leaving for college. Almost everyone in our family carries a Gooloo in their car and have for last 7 years. We even used it recently to jump our $15K RV lithium battery bank. Easy to use, reliable, you're never stranded and always have power for phone charging, etc. They retain a charge for very long periods (my experience 2 years and more without recharge) and recharge quickly. A must for any loved one to keep them safe and independent. Faster to Gooloo jump a car than jumper cables- throw the cables away and don't wait for another vehicle to help. I use before calling AAA.
