Safety note: Jump starters deal with high current. Follow the manufacturer's clamp order and engine-size limits; check the manual before use.
Verdict
The NOCO to buy if you want USB-C fast charging and a bit more headroom than the GB40 without jumping to the heavy GBX155. Still a 1-year warranty.
Pros & cons

- Lighter than the GB40 at 2.16 lb

Best for

Frequently asked questions
How fast does the GBX45 recharge?
NOCO lists about 0.8 hours on a compatible 60 W USB-C Power Delivery charger. The charger is sold separately; a phone charger will take much longer.
Can I jump a frozen or damaged battery with it?
No. NOCO's user guide warns: do not attempt to jump start a damaged or frozen battery, and use only on 12 V lead-acid batteries.
Is 1250 A enough for a V8?
NOCO rates it for gas engines up to 6.5 L, which covers most V8 trucks and SUVs. For diesels over 4.0 L, NOCO points to larger Boost X models.
