F-150, RAM 1500, Diesel Pickup — The NOCO GB70 Is Built for Engines the GB40 Can't Handle
The NOCO GB40 covers most passenger cars and crossovers. The GB70 exists for everything the GB40 can't reach: full-size trucks with V8s, diesel pickups, RVs, boats, and fleet vehicles. 2000A peak current is double the GB40 — not an incremental upgrade, but a different product for a different vehicle class.
The most common reason people buy the GB70 over the GB40: they own an F-150, RAM, or other full-size truck. 5.0L, 5.7L, 6.2L gas engines — those are at or above the GB40's rating. For those vehicles, the GB70 is the correct choice, not an upgrade.

- ✓2000A covers full-size trucks (5.0L–6.2L V8), large diesel pickups, RVs, and fleet vehicles — the GB40 cannot reliably start these
- ✓Same NOCO safety features: spark-proof clamps, reverse polarity protection, error indication before current flows
- ✓USB charging output for phones and devices — functions as a portable battery when not jump-starting
- ✗Heavier and larger than the GB40 — if your daily driver is a sedan or crossover under 4L, the GB40 is sufficient and easier to store

What Verified Buyers Report
The most repeated use case in GB70 reviews is exactly this: full-size Ford, Chevy, or RAM trucks with cold or dead batteries. Multiple buyers describe starting trucks that had sat dead for days.
Consistent theme: buyers who bought the GB70 after a dead battery event (when they had to call a tow truck or wait for a jump) describe the purchase as “should have done this years ago.” The value is clearest in hindsight.
Several buyers in northern states and Canada describe starting diesel engines in -20°F weather. Cold reduces battery capacity significantly — diesel in particular needs more current to start in winter. The GB70 handles this where the GB40 struggles.
Frequently Asked Questions
Check your engine size. Under 6L gas or under 3L diesel → GB40 is sufficient. Over 6L gas, or diesel truck/RV → get the GB70. When in doubt for a V8 truck, get the GB70. Starting a larger engine than the device is rated for risks failing to start and potentially damaging the unit.
Multiple verified buyers confirm starting diesel engines in sub-zero temperatures. Cold reduces battery output capacity by 20–50% — the GB70's 2000A headroom is specifically why it handles this where lower-rated devices fail.
Similar to the GB40 — NOCO rates it for up to 1 year in storage. Check and recharge every 3–6 months. Store indoors when possible; extreme cold or heat degrades lithium-ion charge retention over time.
