NOCO Boost GB50 1500A UltraSafe Portable Jump Starter
More headroom for larger gas engines and diesel trucks without going to the heavy-duty GB70.
- Buy if you drive a full-size truck or large SUV with a 6.0L+ gas engine
- 1500 amps covers diesel engines up to 4.5L that the GB40 misses
- Same safety features as the GB40 in a slightly larger package
Best For / Not For
Best for
- Full-size truck and large SUV owners
- Diesel truck owners with engines up to 4.5L
- Buyers who want GB40-level safety with more amp headroom
Not for
- Compact car owners who are paying for headroom they do not need
- Diesel truck owners with engines larger than 4.5L (need GB70)
- Buyers on a tight budget (the GB40 covers most cars)
Key Details
What Makes It Stand Out
The GB50 is the sensible step up from the GB40 for truck owners. The 500 additional amps translate to meaningful extra headroom on cold mornings when a battery that is 80% discharged needs more current to turn over a large engine.
The diesel coverage expansion to 4.5L is the other practical advantage. Many diesel pickup truck owners run in the 3.0L to 4.5L range, and the GB40's 3.0L diesel ceiling leaves them short.
Value
The GB50 costs more than the GB40 but less than the GB70. If your vehicle falls in the 6.0L to 7.0L gas or 3.0L to 4.5L diesel range, it is the correctly-sized tool for the job.
Pros and Cons
Pros
- 1500 peak amps handles large gas and mid-size diesel engines
- Same spark-proof and reverse polarity protection as GB40
- Gas coverage up to 7.0L, diesel up to 4.5L
- LED flashlight and USB power bank built in
Cons
- More expensive than the GB40 for coverage most car owners do not need
- Slightly larger and heavier than the GB40
- Still not enough for very large diesel trucks (8.0L+)
Bottom Line
Buy the NOCO Boost GB50 if you drive a full-size truck or a diesel vehicle up to 4.5L and want the GB40's safety features with enough extra headroom to handle large engines confidently.
