What’s the difference between NOCO GB40 and GB70?

The main difference between NOCO GB40 and GB70 is their peak current and intended vehicle capacity. The GB70 offers a higher peak current of 2000A, making it suitable for larger engines than GB40, which is rated at 1000A. This means that while the GB40 can handle most standard vehicles, the GB70 is designed for larger or commercial vehicles. For instance, if you're a truck owner or operate heavy machinery, the GB70 would be the better option. Pro tip: evaluate your vehicle requirements against the starter's specifications before deciding. However, if you only need a jump starter for smaller cars or occasional use, the GB40 might be perfectly adequate and more cost-effective.
