NOCO Boost Pro GB150 Review (2027)
In-depth review of the NOCO Boost Pro GB150: 3000 peak amps, diesel rating to 7.0 liters, and a 500-lumen work light.


NOCO Boost Pro GB150
A 3000-amp lithium booster rated for big gas engines and mid-size diesels.
Our verdict
The GB150 is the booster to buy when smaller packs feel marginal: 3000 peak amps and a 7.0-liter diesel rating cover the trucks and work vehicles that strain lesser units. Spark-proof clamps and reverse polarity protection keep it forgiving, and the bright LED plus USB power bank output make it useful well beyond jump duty. It is bigger than commuter boosters, but for diesel and large V8 owners that size buys real starting confidence.
What we like
- 3000 peak amps start gas engines up to 9.0 liters and diesels up to 7.0 liters
- Spark-proof connections and reverse polarity protection make a wrong hookup a non-event
- 500-lumen LED flashlight handles night breakdowns without a second tool
- Doubles as a USB power bank for phones and tablets on the road
What to watch out for
- Noticeably larger and heavier than compact commuter boosters
- Premium price tier compared with the rest of the NOCO Boost line
- More output than a small four-cylinder car will ever use
What owners report: NOCO Boost Pro GB150
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Serious headroom for big gas engines and mid sized diesels makes cold starts feel unhurried
- A very bright work light handles a dark engine bay without holding a phone torch
- Mistake proof connections carry over, so the extra power does not add hookup risk
Common complaints
- Noticeably larger and heavier than commuter boosters, so it lives in the trunk rather than the cabin
- Premium cost is difficult to defend if the household only runs small cars
- Most small engines will never touch the output this pack was built to deliver
Who it is for
Owners of diesel pickups, large gas trucks, and SUVs who want maximum starting headroom in one pack.
Starting power and engine coverage
NOCO rates the GB150 at 3000 peak amps, with gas engine coverage to 9.0 liters and diesel coverage to 7.0 liters. That diesel figure is the headline: it reaches the smaller and mid-size truck diesels that fall outside the ratings of compact boosters, while the gas rating swallows any production V8. As with every lithium booster, a completely frozen, deeply discharged battery still needs a healthy margin, so the rating should be read as coverage, not a guarantee.
Safety systems and the light
The pack is spark-proof and protected against reverse polarity, so clipping it on backwards produces a warning rather than damage. The 500-lumen LED is genuinely bright for engine-bay work and roadside visibility, a step up from the token lights on budget packs. Heavy-duty clamps and a solid housing suit a tool that lives in a truck bed box or under a seat.
Power bank duty and trade-offs
A USB output lets the GB150 charge phones and other small devices, which matters during the same outages and breakdowns that flatten car batteries. The trade-offs are size and price: it is the largest style of handheld booster NOCO sells and sits at a premium tier. Drivers of small cars pay for capacity they will never use, but truck and diesel owners get exactly the reserve they need.

Questions, answered
Will the GB150 start a 6.7-liter diesel pickup?
It is rated for diesel engines up to 7.0 liters, so a 6.7-liter diesel falls inside its published coverage. Very cold weather and a deeply discharged battery reduce any booster's margin, so keep the pack charged and warm when possible.
Can it charge a phone?
Yes. A USB output turns the pack into a power bank for phones and other small USB devices between jumps.
