Score is calculated from the manufacturer's published specifications. BaniCar has not handled this unit. Specs and availability change — verify on the listing.
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 safe default for sedans, crossovers and gas trucks that live in the glovebox. If you drive a diesel or want to charge a laptop off it, move up to the GBX series.
Pros & cons
Pros
- Spark-proof, reverse-polarity-protected clamps with a clear error LED
- IP65 housing rated from -4°F to 122°F
- Light at 2.45 lb and small enough for a glovebox

Cons

- No USB-C Power Delivery; recharge takes about 3 hours at 2 A
- 1-year warranty is the shortest here alongside the GBX models
- Not rated for diesels above 3.0 L
Best for
- Commuters with 4- and 6-cylinder cars
- Anyone who values a decade-long safety record over raw amps

Frequently asked questions
Can I use the GB40 on a frozen battery?
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.
What happens if I hook the clamps up backwards?
The red Error LED lights and no power flows; reverse the clamps to clear it. Manual override mode disables that protection, so NOCO says to use it with extreme care and only on 12 V lead-acid batteries.
Will it start my F-150?
NOCO rates it for gas engines up to 6.0 L, which covers every gas F-150. Diesel is limited to 3.0 L, so a Power Stroke is out — look at the GBX155.
