I had this version and I accidentally let it discharge which, for some reason prevented the USB-C from charging it. I had to fix it by taking the unit apart and forcing a charge into the lithium batteries. It wasn’t as bad as I thought, but it’s just one of those things to just remind people to do not let it fully run out of charge. The GOOLOO team may have fixed this since I bought mine, but if anyone runs into a scenario where it won’t charge putting just a little charge into the lithium batteries should tell the controller that the battery is there thus allowing it to charge.
I’m pretty sure this will boost a 6 litre diesel and up to an 8 litre gas engine ( I was looking at GP 4000s and GP 2000s etc so I might have mixed up the engine sizes ) On the plug that the cables are attached to there is a red light and a green light as well as a small “ boost “ button for batteries that are pretty much dead. Push that button and within about 20-30 seconds that little thing will start 5he engine right up.
Can I ask how long you've had this unit for? If it's been a while, has it lasted? My concern with Lithium polymer batteries is that they puff up after a while.
Bought one in may 2023. Defective from the start, doesn't hold a charge. Contacted them. They do not honor the valid warranty. Typical chinese way of doing business...
Where did you buy the product? From Amazon or Walmart or other platforms.Please leave the order number so that I can forward it to the relevant department for follow-up.
@@gooloo2 I do not have the order number. All I have is the proof of payment from paypal with transaction details on it with seller info HONG KONG HAOWEI TECHNOLOGY CO. That is you the official Gooloo store. (As Stated on your website).
They will never honor the warranty if you have a defective unit like the one I purchased!! Even with proof of purchase!! Typical chinese way of doing business....

I think the device you received is defective. You can contact after-sales customer service on the order, and the customer service staff will handle it for you.
Only press boost if it is blinking green. Blinking means the battery is very low and needs the extra boost. No waiting for AAA. With all the new 💩 in vehicles from gps to everything else people are reluctant to help you jump your vehicle because of damaging sensitive parts. With long cables you could be waiting a long time. Teach the drivers in your family how to use the jump box. Put the cables on then plug into the jump box. Turn key to on and watch the gauges go up. Like the gas gauge. Then turn the key to start. WOW you did it. Now unplug the jump box then remove cables from the battery. Done 😃
It is to distinguish it from GT4000. GT4000 has a heating function and is suitable for use in extremely cold weather, while GT4000S does not have a heating function.
AAA is great for flat tire changes but for a quick jump start then jump starters come in very handy. No waiting around for AAA. Also you don’t need another vehicle like you do with jumper cables. You may even have cables but people are reluctant to help in fear of harming something in there electric system in there vehicles. Teach all the drivers in your family how to use these portable jump starters. You could also bail someone else out some day. Test your alternator with the jump starter. Once your vehicle starts remove one cable. If the vehicle quits you need an alternator. If it keeps running it’s the battery. 😁
Thank you for your feedback. Please contact the after-sales staff through the order. The after-sales service will deal with it as soon as possible after receiving the information.
I bought my Gooloo less than a year ago. Fully charged it. Never used it. After only 1 month sitting there battery is down more than 50% therefore unusable...only 1 month. Recharged, same results....contacted service via email, they say they are on vacation lol....oh well....
Thank you for your feedback. We have a short holiday during the Spring Festival and will start working today. You can contact the after-sales staff through the order form.
RED LIGHT on and solid with beeping: Indicates the connection is wrong, you need to correct the battery clamps as step 2 mentioned, wait the GREEN LIGHT on and solid, then start the vehicle directly.

I have a 5 year old gooloo 1000 watt and it has saved so many people. When I get a request to jump someone I use this instead of cables. The biggest thing I’ve used it on was my f250 5.4 gas v8 but it started it easily with a dead battery. I’ve found it really beneficial for lawn mowers and motor cycles and even my jetski. It saved my vacation when my jetski battery died on a remote camping trip. Mine is finally beginning to have recharge issues and I have to watch it closely when charging as it will suddenly start to discharge while in the charger.
Makes a great paperweight. My GP4000 wouldn't even jump my daily driver 2015 Toyota RAV4 four cylinder, whose battery suddenly died. A new battery and all is back to normal.
