Bests & Worsts Reviews from Amazon

I bought the Noco GB40 a few days ago for my father and I am highly impressed. He has a GMC 5.7L V8 Savana van and has had some intermittent battery issues (something slowly draining the battery). After charging the GB40 I tested it on the van. A jump starter for the average driver is not something that you readily use, however it is very important that it works when you need it the most. In testing, I removed the side post connectors and hooked up the GB40. Then in manual override I was able to start the van. There was a slight hesitation, however it did start within the first 3 seconds. I have used other battery jump starters and this was the only one that I found that would start his van. Since the rating for the GB40 is towards the upper limit of his van, I bought another Noco, this time the GB70 for him. I didn't want to take any chances of it not starting (although it did without the battery). I will just keep the GB40 for my Jeep Renegade. In conclusion, this review is for the GB40. The Noco products are VERY well made and the clamps are excellent. Well worth the price and highly recommended.
