Engine rating against the rest of the line
Where the GB70 sits in the line
The jump from the GB40 is mostly about diesel: 3.0 liters becomes 6.0. The battery more than doubles too, from 24 to 56 Wh.
The GB70 also adds a 12 V output port rated at 15 amps on NOCO's spec page, so it can run a tire inflator or other 12 V accessory.
If you are choosing between this and the Boost X GBX75, compare the table below. The GBX75 has a higher rating on paper and a larger battery, and weighs less.
