    • Just as good as NOCO
Color: GT4000-Red
This is a fantastic compact jump starter. While I haven’t yet tested it to its full potential, it easily jump-starts a fully dead 5-liter gas V8 engine. I will provide an update once I try it on my diesel truck, but I’m confident it will perform well. Each jump start uses only about 3-5% of the battery, and the unit quickly recharges with the included car charger. Impressively, it delivers up to 100 watts while charging in the car. I would definitely recommend this product and would purchase it again when the time comes to replace it. Although I haven’t had to contact GOOLOO’s customer support, they seem to have a solid reputation for backing their products. However, I do recommend considering the purchase of GOOLOO’s hard case, as the provided bag can be challenging to fit everything in feel like the unit is protected. While a hard case would be a better inclusion, I can’t complain too much given the unit's price. TL;DR: Excellent product, excellent price. ... show more

After much research I chose this jumpstarter. It is simple to use with the LCD screen. Perhaps it's biggest benefit is a full charge can be achieved in about an hour and twenty minutes. It will work from -40 degree to 140 degree temperatures. This is the only difference I can see between this model and the GT4000S which has a -4 degree to 140 degree operating temperature range. It weighs 2.42 pounds and measures 9.01L x 3.89W x 2.08H. It comes with a bag and cables to charge with. The clamps and cables measure about 18 inches long and are aliitle of a 1/2 inch wide. This will work on SUV's, cars and large trucks. ... show more

    • Great jump pack
Color: GT4000-Red
This small unit jumps a vehicle with ease. Has a high enough capacity to be able to jump several times before needing charged although I would recommend charging it sooner. Seems pretty durable and functions great at a price point that can not be beaten. There is a review of this unit on project farm you tube channel that says it all. Great product. ... show more

    • 10 Second Jump
Color: GT4000-Red
I’ve had other brands, and none have been as easy and quick as this one. I was totally amazed at the power and ease to start vehicle. We recently had a dump truck that wouldn’t start and the regular standup, plug in unit wouldn’t start it. They had it on charger and jumper for over 20 minutes. They completely used up any charge. I hooked up my GooLoo and in less than 20 seconds the truck came to life. It amazed my coworkers enough to have them request all the buyer info I had for them to order their own. The unit is very substantial in build quality. The weight, materials, and just overall build quality. I would buy another if needed. I just wish I’d bought this one before wasting my monies on the other brand. I would recommend this to anyone to at least give a try, especially with pricing the way it is now. I got a great deal and it’s now like $40 less than what o gave. I do recommend the add on purchase of the hard case. Very nice case that stores unit securely and is at a very affordable price. Just give it a try, and I’ll bet you will be as happy with your purchase as I have been. Thank you Amazon for carrying and offering at such great prices. ... show more

    • NEVER WORKED RIGHT - BUYER BEWARE!!!!
Color: GT4000-Red
I wanted to love this device, it worked for a slightly low battery but over the past year over a dozen times I have attempted to use this on scooters, motorcycles, honda civic, toyota 4runner, BMW 540I and it has failed to help when I needed it most. Tonight was the last straw, I tried it one last time and it didn't work on my fathers motorcycle who was stranded. I have followed the instructions step by step and I cannot get this paper weight to work. The boost function has never worked. I know it has been a year and I don't usually leave reviews but BUYER BEWARE, THIS DOES NOT WORK! IT WILL LEAVE YOU ON THE SIDE OF THE ROAD WISHING IT WORKED! Waste of $130. highly frustrated.... ... show more

    • It is great
Color: GT4000-Red
It works very well. It's great. I'm very impressed with the quality. I watched a youtube videos that compared it to similar devices and it performed very well for the price. I don't personally have anything to compare it to, but it did jump my car just fine. Two things I wish for: 1. I wish you could turn off the display when you are using it to charge or power a USB device. The display is bright and wastes power if you don't need to look at it. It's also too bright if it's on my nightstand and I'm trying to sleep. 2. I also wish you could charge a car battery. You can't charge a car battery because it won't stay powered up for more than 30 seconds, just long enough to jump start a car. I wish you could keep it powered on until the Gooloo was drained. You might have to recharge the Gooloo 10 times, I don't know many times it would take, but it's not an option because it won't stay on at 12 volts. ... show more

    • Just arrived haven't tried it.
Color: GT4000-Red
I like this Unit it has a very nice large easy to read LCD screen. The jumper cables seem to be heaver than the GP4000, it also come with charging cords unlike the GP4000, it displayed its charge rate in watts and percentages of charge. Not having to use this unit yet is a disadvantage but I had to say that it appears to be a far better product than the GP4000 which I returned and Purchased this GT4000 with cold weather warm up feature. I expect this to work well if and when I ever need it. I got this for traveling so it will be packed for trips. If I have a failure of this unit I will up date this review ... show more

    • Fantastic
Color: GT4000-Red
I've had this for about a year sitting in my truck. Needed it one day and it still showed 100% charge. I've used this twice now and it has worked perfectly. Well worth the money.
