NOCO Boost GB150 review
NOCO Boost GB150: 3000A UltraSafe Jump Starter Power Pack – For 9.0L Petrol and 7.0L Diesel Engines
By Tom Calder
A well-built jump starter for genuinely large engines - petrol up to 9.0 litres and diesel up to 7.0 litres - from a brand with a strong safety-engineering reputation. Treat the 3000A peak-amp figure as a marketing number rather than a true cranking-amp rating, and, like any lithium pack, keep it indoors rather than in a hot car over summer.
- Best for
- Owners of large 4x4s, pickups, vans or big diesel engines who want serious jump-starting headroom in one unit.
- Skip it if
- You drive a standard petrol car or small diesel

What we like
- Reverse-polarity protection and spark-proof clamps make it safe to use even for non-mechanics
- Genuinely rated for large diesels up to 7.0L and big petrol engines up to 9.0L, where smaller jump starters fall short
- A 500-lumen torch with SOS mode and a 12V accessory port add everyday utility, though USB charging in and out is a modest 5V/2.1A rather than fast
Worth knowing
- The 3000A peak-amp figure is a marketing number, not a true cranking-amp rating - the litre coverage is the more honest guide
- Considerably pricier than NOCO's smaller GB40/GB70 units, and overkill for a standard petrol hatchback or family car

Our review
NOCO's heavy-duty Boost: an 88Wh lithium pack rated at 3,000A peak for petrol engines up to 9.0L and diesels up to 7.0L, with up to 80 starts a charge and a 500-lumen torch. The figure that matters is that 7.0L diesel rating; among the NOCO packs on our site only the larger GBX155 goes higher. It suits owners of large 4x4s, vans, motorhomes and boats; a family hatchback does not need it.
What the numbers mean
NOCO rates the GB150 at 3,000A peak and, more usefully, for petrol engines to 9.0L and diesels to 7.0L. Peak amps describe a momentary surge and NOCO publishes no sustained cranking current, so the litre ratings are the honest guide, and 7.0L of diesel is well beyond a typical family car; NOCO pitches it at trucks, boats, RVs and SUVs as well as cars. The 88Wh battery is what gives it up to 80 jump starts on one charge by NOCO's count, and up to six smartphone recharges from the USB port. A built-in voltmeter shows the vehicle battery's voltage, and a manual override, held for three seconds, forces a boost into a battery too flat for the pack to detect.
On the road, in a British winter
NOCO rates the GB150 to operate from -20°C to +50°C, so a frosty start is within its range, though charging is limited to 0°C to +40°C, which means topping it up indoors rather than in a cold van. NOCO's guide allows no more than five attempts in 15 minutes, then a 15-minute rest. At 2.9kg and 315 by 185 by 69mm it is a boot or workshop tool, not a glovebox one. Beyond starting, the 12V XGC output supplies 15A, which NOCO says will run 12V devices such as tyre inflators and power inverters, and the 500-lumen torch has seven modes including SOS and strobe for a dark verge. The connection order, and when not to attempt a start, are in how to jump start a car.
How it compares
The NOCO Boost X GBX75 is the newer design: 2,500A peak, 8.5L petrol and 6.5L diesel from a 74Wh battery, 1.71kg, and a 60W USB-C port that refills it in 1.7 hours, against the GB150's 10W USB-C input. The CTEK RB 4000 matches the GB150's battery at 88.8Wh, publishes a 2,060A cranking figure, weighs 1.21kg and charges in 3.5 hours at 30W. For 24V trucks the VTOMAN V-Truck switches between 12V and 24V. More on our jump starter comparison.
Living with it
Charging is the GB150's weak point. The USB-C input is 5V at 2.1A, about 10W, and NOCO's datasheet puts a full recharge from a 2A USB source at about 11 hours; NOCO's 3-hour figure is for the 12V XGC input at 5A from a car socket, using the supplied adapters. USB output is the same 10W, fine for a phone and slow for a tablet. The box includes XGC 12V male and female adapters, an XGC extension cable, a USB-C cable and a storage bag. The shell is IP65 with the port covers closed. NOCO's spec page lists a one-year warranty, and its warranty terms say UK buyers may get a minimum of two years.
Safety and storage
Spark-proof clamps and reverse-polarity protection mean a wrong connection lights a red error rather than arcing. NOCO's guide says not to jump a damaged or frozen battery, to work in a ventilated space and to wear eye protection; manual override switches those protections off, so it is a last resort. The guide gives a storage range of -20°C to +50°C with a daily average of 0°C to +25°C, and warns that an unused pack discharges over time, so store it indoors and charged and check it every few months; charge it only between 0°C and +40°C. Our lithium battery fire safety guide has the household rules. A battery that keeps going flat is a job for a garage or a maintenance charger.
Our verdict
Buy the GB150 if you run a large diesel 4x4, a van, a motorhome, a boat or farm machinery and want one pack with real headroom and a long run of attempts. Skip it for a family car: the GBX75 starts almost as large an engine, weighs 1.2kg less and takes a 60W charge against the GB150's 10W, and a GB40 or GB70 covers most hatchbacks and estates for less.

Who shouldn't buy this
Don't buy it if you drive a standard petrol car or small diesel - a smaller, cheaper NOCO unit (like the GB40 or GB70) will start it just as reliably for less money.

Best for Drivers who want one mid-size jump starter that covers most family cars and small diesels, rather than buying NOCO's biggest (and priciest) unit just in case.

Can the NOCO GB150 start a 7-litre diesel?
NOCO rates it for diesel engines up to 7.0L and petrol engines up to 9.0L, on 12V lead-acid batteries. It is a 12V-only unit, so a 24V truck system needs a different pack.
How long does the NOCO GB150 take to charge?
NOCO quotes a 3-hour recharge from its 12V XGC input at 5A, using the supplied car-socket adapter. Over the USB-C input, 5V at 2.1A, NOCO's datasheet gives about 11 hours from a 2A source and 22 hours from 1A.
How many jump starts does the GB150 give per charge?
NOCO says up to 80 jump starts on a single charge of the 88Wh battery, and up to six smartphone recharges if you use it as a power bank instead.
How heavy is the NOCO GB150?
NOCO's specification lists 2.9kg and 315 by 185 by 69mm, so it belongs in the boot or the workshop rather than a door pocket.
