Which NOCO jump starter fits your vehicle?
The best NOCO jump starter is the smallest model whose stated engine range covers your vehicle, with enough margin for the way you plan to use it. These picks range from the GB20 for gas engines up to 4.0L to the GBX155 for gas engines up to 10.0L and diesel engines up to 8.0L.
Peak amps are useful for comparing models, but they do not replace checking your engine size and fuel type. NOCO describes spark-proof and reverse-polarity protection on both classic Boost and Boost X models; the Boost X line adds UltraSafe 2.0, a 60-second timer, and two-way USB-C Power Delivery.

Cons
- Weighs 7 lb
- Largest form in this group
The GBX155 is the clearest fit for very large engines in this group, with a stated range up to 10.0L gas and 8.0L diesel. It also makes sense for buyers who want a high-output jump starter that can serve as a USB-C power source for other devices.
Its 60 W USB-C Power Delivery works in both directions. NOCO states a 2.7-hour recharge, or enough charge for one jump start after 5 minutes, even from a depleted battery.
The GBX155 weighs 7 lb and is rated for up to 18 starts per charge. Choose it when engine capacity and USB-C charging justify the size; skip it for an ordinary car that fits a smaller model.

- Two-way USB-C charging
- 100-lumen flashlight
Cons
- Up to 6 starts per charge
- Larger engine fit may not be needed for smaller cars
The GBX45 suits buyers who want a quick recharge and a little more engine range than the GB40. It supports gas engines up to 6.5L and diesel engines up to 4.0L.
NOCO states that it can recharge in 48 minutes using USB-C Power Delivery, or gain enough power for a jump start in 5 minutes. The trade-off is capacity for repeated starts: it’s rated for up to 6 starts per charge.
At about 2.6 lb, it remains relatively easy to carry. Choose it if fast charging and two-way 60 W USB-C matter; skip it if you want more starts between charges or don’t need the USB-C features.
NOCO Boost GBX75: Best for drained batteries
- 2,500 amps
- Gas engines up to 8.5L
- Diesel engines up to 6.5L

This Boost X model has substantial engine capacity, two-way USB-C power, and a manual override feature for batteries below 3V.
Pros
- Up to 12 starts per charge
- Can gain jump-start power in 5 minutes
- 400-lumen flashlight
Cons
- Weighs 5 lb
- Standard low-wattage phone chargers take longer
The GBX75 suits larger engines and includes a manual override for a vehicle battery below 3V, when the safety sensors may not detect it. It supports gas engines up to 8.5L and diesel engines up to 6.5L.
It can gain enough charge for a jump start in 5 minutes, and NOCO states a 1.8-hour recharge when using a 60 W USB-C Power Delivery charger. A standard low-wattage phone charger takes significantly longer.
It weighs 5 lb and is rated for up to 12 starts per charge. Choose it for the engine range, USB-C charging, or manual override; skip it if your battery is above the detection threshold and a smaller model already covers your engine.

The GB150 is built around large engine limits and a stated 80 starts per charge, with a 500-lumen flashlight and power bank.
Pros
- Highest stated start count here
- IP65-rated housing
- Spark-proof and reverse-polarity protection
Cons
- Weighs 7.5 lb
- Recharges in 7 hours
The GB150 is the classic Boost option for large vehicles and buyers who value a high stated number of starts per charge. Its engine limits reach 9.0L gas and 7.0L diesel.
NOCO rates it for up to 80 starts per charge, the highest stated figure among these picks, and a 7-hour recharge. The 500-lumen flashlight has seven modes.
At 7.5 lb, it is a substantial unit to keep in a car. Choose it when repeated starts and large-engine support matter more than Boost X USB-C Power Delivery; skip it if you want a faster recharge or a lighter pack.
The GB150 and GBX155 comparison focuses on their main trade-offs.

NOCO states a 1.2-hour recharge and up to 9 starts per charge. Like other Boost X models here, it can gain enough charge for one jump start in 5 minutes.
It weighs 3.4 lb and includes a 200-lumen flashlight. Choose it when you want USB-C charging in a smaller package than the GBX75; skip it if your engine needs more capacity or you prefer the classic Boost line’s higher stated start counts.
NOCO Boost GB20: Best for compact cars
- 500 amps
- Up to 20 starts per charge
- Gas engines up to 4.0L
- Compact 2.4 lb form
A smaller-engine option with a power bank, 100-lumen flashlight, and spark-proof and reverse-polarity protection.
Pros
- Light 2.4 lb form
- Up to 20 starts per charge
- IP65-rated housing
Cons
- Gas engine limit is 4.0L
- No diesel engine capacity specified
The GB20 is the compact choice for a gas engine up to 4.0L. It fits a smaller car or other gas-powered vehicle within that limit, but it has no stated diesel engine range.
It is rated for up to 20 starts per charge and recharges in 3 hours. The power bank and 100-lumen flashlight add convenience for a roadside kit, and the model includes spark-proof and reverse-polarity protection.
At 2.4 lb, it is easy to store. Choose it when compactness is the priority and the engine is within range; skip it if you want more flexibility for a larger vehicle, since the GB40 covers a wider range.
How do Boost and Boost X compare for a NOCO jump starter?
Classic Boost models focus on jump-starting, a power bank, and core safety features, while Boost X models add two-way 60 W USB-C Power Delivery. Boost X versions also include a 60-second timer and state that 5 minutes of charging can provide enough power for one jump start.
The classic GB40, GB50, GB70, GB150, and GB20 state recharge times from 3 to 7 hours. Boost X recharge times vary by model, from 48 minutes for the GBX45 to 2.7 hours for the GBX155, when charged as specified.
Choose classic Boost if you want a familiar set of jump-start and power-bank functions. Choose Boost X if charging other USB-C devices or recovering charge quickly is useful, and check whether you can use the recommended charging power for the model.
How should you choose a NOCO jump starter?
Choose by engine range first, then weigh the device’s size, recharge time, and stated starts per charge. A higher peak-amp number is not a reason to carry a heavier unit if a smaller model already covers your vehicle.
Check the engine displacement and fuel type in your owner manual. Match those details to the model’s stated maximum, and leave a sensible margin if you expect to use the same unit with more than one vehicle.
Think about where you’ll keep the jump starter. The GB40 and GB20 weigh 2.4 lb, while the GB150 weighs 7.5 lb; a more powerful model may be less convenient if you need to carry it from home to several vehicles.
Decide whether USB-C charging is a real need. Boost X models can also power compatible devices through USB-C, but a classic Boost model may suit you better if your main goal is a compact emergency jump starter.

How do you set up and care for a NOCO jump starter?
Charge the unit before an emergency, keep its cables and clamps with it, and learn the connection sequence in the model’s instructions. A jump starter that has been stored unused still needs periodic attention so you don’t discover it is depleted when your car won’t start.
Choose a storage spot where you can reach the unit and clamps together. Keep the charging cable with the jump starter, and recharge after using it so it is ready for the next time.
For a jump start, switch off the vehicle and any accessories, then follow the model instructions for connecting the clamps to the battery. Keep the clamps from touching each other, confirm the connections before starting, and remove them in the order the instructions specify.
Don’t keep cranking if the engine does not start promptly. Check the connections and battery condition, allow the unit to rest as directed, and seek help if the vehicle still won’t start.
Boost X models use a high-voltage design and 60-second timer, so follow the model’s specific timing and charging directions. The GBX75’s manual override is for situations where the battery is below 3V and the safety sensors may not detect it, not a routine step for every jump.
What mistakes should you avoid when choosing or using one?
The most common buying mistake is choosing by peak amps alone. Verify the engine’s fuel type and displacement, then compare the model’s stated limits before deciding whether extra capacity is worth the extra weight.
Another mistake is assuming all NOCO models recharge at the same speed or support the same device charging. Boost X models include 60 W USB-C Power Delivery; classic Boost models state recharge times ranging from 3 to 7 hours.
Don’t assume a fully drained vehicle battery will always be detected in the usual way. The GBX75 specifically includes manual override for a battery below 3V, but using an override changes the normal safety process, so use it only as instructed.
Avoid storing the jump starter after a use without restoring its charge. Also avoid guessing at clamp placement or disconnect order.
Use your vehicle’s guidance and the jump starter’s manual, especially if your battery is hard to reach.
Which NOCO jump starter should you choose?
Pick the GB40 for everyday cars, the GB50 when you want more engine headroom, and the GB70 for larger SUVs and trucks. Choose the GBX155 for the largest engines here, the GB150 for its high stated start count, or a Boost X model when fast USB-C charging matters.
The best NOCO jump starter is the one that covers your engine and is practical to keep charged and within reach. If you’re still deciding whether to carry one, read are jump starters worth it? for a broader look at when the backup is useful.
