NOCO rates its Boost Pro GB150 at 3,000 peak amps, enough for gasoline engines up to 9.0 liters and diesel engines up to 7.0 liters, according to the company’s product and spec pages. The 12V lithium-ion jump starter packs an 88Wh internal battery, a 500-lumen flashlight with seven modes, an integrated voltmeter, and a 12V, 15A output for running accessories like tire inflators. NOCO lists it at $299.95 and says it can deliver up to 80 jump starts on a charge. This review covers what that means for trucks, boats and RVs, how it charges, and how it compares with NOCO’s other Boost models.

NOCO’s two weight figures differ. The 6.39 lb on the spec page may describe the unit alone, while 7.5 lb may include the attached clamps and cables; NOCO doesn’t say. Either way, it’s sized for a truck’s rear seat or a boat locker rather than a small storage cubby.
Which Vehicles It Covers
In everyday terms, that rating covers nearly every passenger car and gas pickup on the road, including heavy-duty gas trucks, plus the common 6.6- and 6.7-liter diesel heavy-duty pickups, which sit just under its diesel limit. Large motorhome diesels of around 9 liters and up are beyond its diesel rating. Check your owner’s manual for your engine size.
Compression-ignition engines take more cranking current than gasoline engines of the same displacement, especially when cold, which is why NOCO’s diesel rating is lower. For a deeper look at matching a starter to a diesel, see our guide to jump starters for diesel trucks.
Where It Sits in NOCO’s Lineup
NOCO’s Boost range runs from the 1,000A GB40 up through a 2,000A model at $199.95, the 3,000A Boost Pro reviewed here, and the 4,250A GBX155 at $369.95. The GB150’s larger battery, more than three times the GB40’s, matters if you plan to use it as a 12V power source as well as a jump starter. If your vehicles all have gas engines under 8.0 liters, NOCO’s 2,000A model in our GB70 review is the cheaper option. For a compact unit, see my hands-on NOCO GB40 review.
Beyond Jump Starting: The 12V and USB Ports
The Boost Pro’s 12V port can output 12V at up to 15A, about 180W, using the included female 12V adapter. That’s enough for most portable air compressors, a small 12V cooler or a 12V light, according to NOCO, which lists tire inflators and power inverters among the uses. With 88Wh of storage, our estimates for running 12V accessories from a full charge:
| Device | Typical draw (estimate) | Approximate runtime (estimate) |
|---|---|---|
| Portable air compressor | ~120W | ~35 minutes of running |
| 12V LED work light | ~20W | ~3.5 hours |
| Phone charging (USB, ~13Wh per charge) | — | Up to 6 charges (NOCO) |
| 12V cooler (thermoelectric) | ~45W | ~1.5 hours |
Running accessories uses battery you may need for a jump, so it’s smart to keep it above about half charge on the road.
Recharging the Pack
NOCO lists two ways to recharge the pack:
- 12V input, 5A: about 3 hours from empty using the included male 12V adapter in a car socket. This is the fastest option.
- USB-C, 5V at 2.1A: about 10.5W. NOCO doesn’t publish a USB-C charge time, but at that rate a full charge from empty would take roughly 8–9 hours or more by our estimate. It’s an overnight option.
The box includes a USB-C to USB-C cable and NOCO’s 12V male and female adapters plus an extension cable, but no wall charger, so plan on a USB charger you already own or the 12V route.
The Voltmeter and Flashlight
NOCO’s integrated voltmeter shows the vehicle battery’s voltage when connected, which helps you understand the problem before you jump. A reading near 12.6V on a resting battery usually means it’s charged, while a much lower reading points to a discharged battery or a parasitic drain. The 500-lumen flashlight has seven modes, including SOS and an emergency strobe, which is useful for roadside stops at night.
Reading the Voltmeter
These are typical resting-voltage readings for a 12V lead-acid starting battery that has sat for a few hours with the engine off. They’re general guidelines, not NOCO figures, and temperature shifts them slightly.
| Resting voltage | Approximate state of charge | What it suggests |
|---|---|---|
| 12.6V or higher | ~100% | Healthy and charged; a no-start may be something else, like the starter or a connection |
| ~12.4V | ~75% | Fine, but worth a charge |
| ~12.2V | ~50% | Low; may struggle in cold weather |
| ~12.0V | ~25% | Likely to need a boost |
| Below ~11.8V | Discharged | Boost it, then recharge fully and test the battery |
Before you start, follow NOCO’s user guide and your owner’s manual for the connection steps; some vehicles route the connection to remote posts under the hood instead of the battery itself.
When a Jump Isn’t the Whole Fix
A jump starter gets you moving, but it doesn’t tell you why the battery died. After a successful start, a few checks help avoid a repeat:
- Drive long enough to recharge. A short trip after a jump may not restore enough charge for the next start.
- Check the resting voltage the next morning. The built-in voltmeter makes this easy. If the battery is well below about 12.4V after sitting overnight, it may be failing or something may be draining it.
- Look at the charging system. If the battery drains while driving, the alternator or a loose connection may be the cause; a parts store or mechanic can test it.
- Replace an aging battery. Lead-acid starting batteries typically last several years; if yours is old and needs frequent jumps, replacement is often the real solution.
For RVs and boats with a separate house battery, a battery monitor can show what’s draining it. Our Renogy Shunt 300 review covers one option.
Who Gets the Most From It
Households with a mix of vehicles. One unit covers a compact car, a gas pickup and a heavy-duty pickup, so it can live in whichever vehicle is going on the longest trip.
Boaters. The IP65 rating with ports closed suits a dry locker on a boat. Keep it stowed in its bag, away from bilge water, since IP65 isn’t a submersion rating.
Work trucks and farms. Up to 80 jumps per charge, per NOCO, means it can handle several vehicles on a cold morning before it needs a recharge, and the 12V output can run an air compressor for a low trailer tire.
Overlanders and campers. A dead starting battery far from help is the scenario this kind of unit is made for. Pair it with a way to recharge on the road, like the 12V input from a running vehicle or a power station’s 12V socket. Our overlanding power station picks cover the second option.
Jump Starter, Jumper Cables or Battery Charger?
| Tool | Needs another vehicle? | Best for | Limitations |
|---|---|---|---|
| Portable jump starter | No | Getting started alone, anywhere | Has to be kept charged |
| Jumper cables | Yes | Cheap backup in the trunk | Useless if no one stops to help |
| Plug-in battery charger | No, but needs an outlet | Restoring a flat battery overnight at home | Slow; not for the roadside |
Many owners keep a jump starter in the vehicle and a smart charger in the garage. The jump starter handles the emergency; the charger brings the battery back to full afterward, which is gentler than relying on the alternator alone.
Storage Tips
- Recharge after each use and every few months in storage.
- Keep it in the included microfiber bag, or NOCO’s optional GBC015 EVA case ($34.95), to protect the clamps.
- Avoid leaving it on a dashboard in summer sun.
FAQ
What size engine can the NOCO GB150 start?
Gas engines up to 9.0 liters and diesel engines up to 7.0 liters, per NOCO.
How many jump starts does it give per charge?
Up to 80, according to NOCO.
How long does it take to charge?
About 3 hours with the 12V, 5A input. USB-C charging at 10.5W is much slower.
Can it power a tire inflator?
Yes. The 12V output supplies up to 15A, which covers most portable inflators.
How much does it weigh?
NOCO’s spec page lists 6.39 lb and its product description says 7.5 lb.
Is it waterproof?
It’s rated IP65 with the ports closed, which means dust-tight and protected against water jets, not submersion.
Bottom Line
The NOCO GB150 is a strong fit for heavy-duty pickups, large gas engines, and boats, plus most heavy-duty diesel pickups. Its large internal battery and 15A 12V output also make it a capable roadside power source. If your engines are smaller, NOCO’s 2,000A model saves $100; for very large diesels, look at NOCO’s GBX155 or higher.
