Our recommendation
Choose the GB40 if you drive a gas car or small SUV: 1000 peak amps, 6.0L gas coverage, lighter, cheaper, and easier to store. Choose the GB70 if you drive a truck, large SUV, or diesel: 2000 peak amps and 6.0L diesel coverage are not optional at those engine sizes. Both share NOCO's spark-proof safety system and winter ratings.
Power and engine ratings
The GB40 delivers 1000 peak amps for gas engines to 6.0L and diesels to 3.0L. The GB70 doubles to 2000 peak amps for gas to 8.0L and diesels to 6.0L. The right choice is entirely a function of what is under your hood.
Size, weight, and storage
The GB40 is compact enough for a glove box or door pocket. The GB70 is a trunk unit: heavier, bulkier, and built for bigger jobs. Daily-carry convenience favors the GB40.
Capacity and extras
The GB70's 56 watt-hours give more start attempts per charge and longer accessory runtime. Both include USB device charging and LED lights; neither will disappoint on features.

Yes. Spark-proof connections and reverse-polarity protection are standard on both.
