Our verdict
This is a diesel-and-deep-cold question. The GB70 covers nearly every gas vehicle and light diesels; the GBX155 exists for 6.7L and 6.6L diesel pickups, plow trucks, RVs, and farm equipment that need sustained high current at -20°F, and it adds 65W USB-C charging in both directions. If you don't own a big diesel or work in brutal cold, the GBX155 is an expensive way to get a GB70.
Pick the NOCO if…
- ✓Heavy-duty diesel pickup, RV, or ag equipment
- ✓Routine -15°F and colder starts
- ✓You want fast USB-C recharging and a laptop-capable power bank
Pick the NOCO if…
- ✓Gas engines up to 8.0L or diesels up to 6.0L
- ✓Budget and portability matter
- ✓You want a 12V accessory port
