Evaluation Criteria for Jump Starters
We evaluated the listed NOCO specifications for starting current, listed engine compatibility, charging features, portability, safety functions, and additional roadside capabilities. The comparison also considered the stated price of each model. The published data included zero total Amazon reviews and no customer excerpts, so customer feedback could not be used as evidence.
Compatibility comes first. A higher amp number does not automatically make a unit the right choice if your vehicle’s engine exceeds the manufacturer-listed limit or if you do not need the added size and cost. The recommendations therefore separate compact gas-engine models, diesel-capable options, high-capacity units, and models with extra functions.
Best Options
NOCO Boost GB70: Best for Most Large Vehicles
Why it stands out: The GB70 offers 2,000 amps and is listed for gas engines up to 8.0L and diesel engines up to 6.0L. That gives it broader stated compatibility than the smaller GB20, GB40, GB50, and GBX45 without reaching the price of the highest-capacity models.
The manufacturer lists up to 40 starts per charge, a 400-lumen flashlight with seven modes, a power bank, spark-proof technology, reverse-polarity protection, and an IP65-rated housing. Its listed price is $199.95.
Avoid if: You only need support for a small gas engine, want USB-C fast charging, or require a built-in tire inflator. The published specifications list a six-hour recharge time and do not identify the GB70 as an air-compressor model.
NOCO Boost X GBX155: Best for Maximum Engine Compatibility
Why it stands out: With a manufacturer-listed 4,250 amps, the GBX155 has the highest starting rating in this group. It is listed for gas engines up to 10.0L and diesel engines up to 8.0L, making it the clearest choice for very large engines within the listed lineup.
It also includes USB-C Power Delivery rated at 60 watts, dual-direction charging, a 500-lumen flashlight, a 60-second timer, and UltraSafe 2.0 protection. The manufacturer lists a 2.7-hour recharge time, or enough charge for a jump start after five minutes of charging, even from a depleted unit. Price is $369.95.
Avoid if: Your vehicle is a smaller gas-powered car and you do not need the extra engine capacity. It is the most expensive option in this comparison, and the manufacturer lists up to 18 starts per charge, fewer than some lower-output models.
NOCO Boost Air AX65: Best for Jump Starting and Tire Inflation
Why it stands out: The AX65 is the only listed model that combines a jump starter with an air compressor. It is listed at 2,000 amps for gas engines up to 8.0L and diesel engines up to 6.0L, while its inflator is rated at 67 liters per minute and supports tires up to 35 inches.
The manufacturer lists automatic pressure control from 15 to 100 PSI, selectable PSI, kPa, or bar units, USB-C charging, UltraSafe 2.0 protection, a power bank, and an LED flashlight. Its stated price is $254.95.
Avoid if: You want the lightest or least expensive emergency jump box. The published information does not provide a weight, recharge time, number of starts per charge, or flashlight output for the AX65. Buyers who already carry a separate inflator may also find the added function unnecessary.
NOCO Boost X GBX45: Best for Fast Recharging
Why it stands out: The GBX45 is rated at 1,250 amps and listed for gas engines up to 6.5L or diesel engines up to 4.0L. Its key advantage is charging speed: the manufacturer lists a 48-minute recharge time with USB-C Power Delivery and enough charge for a jump start after five minutes.
Other listed features include 60-watt USB-C Power Delivery, dual-direction charging, a 100-lumen seven-mode flashlight, a 60-second timer, and UltraSafe 2.0 protection. The listed price is $124.95.
Avoid if: Your vehicle has an engine larger than the stated 6.5L gas or 4.0L diesel limits, or if you need the highest number of starts per charge. The manufacturer lists up to six starts per charge.
NOCO Boost GB20: Best Compact Value for Smaller Gas Engines
Why it stands out: The $68.00 GB20 is the least expensive model in the listed lineup and weighs 2.4 pounds according to the manufacturer-listed specifications. Its 500-amp output is intended for gas engines up to 4.0L, and it includes a power bank and 100-lumen flashlight.
It also has spark-proof and reverse-polarity protection, an IP65-rated housing, and a listed capacity of up to 20 starts per charge. The manufacturer lists a three-hour recharge time.
Avoid if: You drive a diesel vehicle or have a gas engine above the stated 4.0L limit. It has the lowest peak-current rating here and is not the appropriate pick for large trucks, heavy-duty equipment, or buyers seeking broad diesel compatibility.
NOCO Boost X GBX75: Best Step-Up X-Series Option
Why it stands out: The GBX75 increases output to 2,500 amps and is listed for gas engines up to 8.5L or diesel engines up to 6.5L. It provides more stated engine capacity than the GB70 and includes the X-series USB-C fast-charging system.
The manufacturer lists a 1.8-hour recharge time with 60-watt USB-C Power Delivery, a five-minute partial-charge jump capability, up to 12 starts per charge, a 400-lumen flashlight, a 60-second timer, and UltraSafe 2.0 protection. Price is $249.95.
Avoid if: You want the most starts per charge, the largest engine compatibility, or a built-in inflator. Its listed 12-start capacity is lower than the standard GB70’s stated 40 starts, and the published data does not identify an air compressor.
Compatibility and Buying Guidance
Before choosing a NOCO jump starter, compare your engine size with the manufacturer-listed maximum for both gasoline and diesel applications. Do not treat peak amps as a substitute for compatibility. The GB20, for example, is listed for up to 4.0L gas engines but has no diesel limit listed here, while the GB40 is listed for up to 6.0L gas and 3.0L diesel.
All 10 products are described as 12V jump starters and include safety features intended to reduce connection errors. The standard UltraSafe models list spark-proof and reverse-polarity protection. The X-series models list UltraSafe 2.0, along with enhanced thermal efficiency and power management. These features support safer operation, but the clamps still need to be connected according to the vehicle and product instructions.
Charging is another important difference. Standard models list recharge times from three to seven hours. The X-series units use USB-C Power Delivery, with the GBX45 listed at 48 minutes, the GBX55 at 1.2 hours, the GBX75 at 1.8 hours, and the GBX155 at 2.7 hours. The published data does not provide a recharge time for the AX65.
Buying Factors That Matter
- Match the engine: Select a model whose listed gas or diesel limit exceeds your vehicle’s engine size.
- Consider vehicle type: Small gas cars can use the GB20 or GB40, while larger trucks and diesel vehicles need a model with an appropriate listed diesel rating.
- Decide whether speed matters: Choose an X-series model if USB-C Power Delivery and rapid recharging are priorities.
- Check portability: The listed weights range from 2.4 pounds for the GB20 to 7.5 pounds for the GB150. Weight is not provided for every model.
- Think beyond starting: Every listed model includes a power bank and LED flashlight, while only the AX65 adds a listed air compressor and tire-pressure controls.
- Budget realistically: Prices range from $68.00 to $369.95. Paying more generally buys higher listed engine capacity, faster charging, or additional roadside functions, but not every vehicle needs those upgrades.
Common Buying Questions
Which NOCO jump starter is best?
For many larger cars and trucks, the GB70 is a balanced choice because it is listed at 2,000 amps for engines up to 8.0L gas or 6.0L diesel. The best choice depends on your vehicle and whether you need features such as fast USB-C charging or tire inflation.
What is the most powerful NOCO jump starter?
The GBX155 has the highest manufacturer-listed peak output in this comparison at 4,250 amps. It is listed for engines up to 10.0L gas and 8.0L diesel.
Which NOCO jump starter is best for a diesel truck?
Choose based on engine size. The GBX155 has the highest listed diesel limit at 8.0L, followed by the GB150 at 7.0L, the GBX75 at 6.5L, and the GB70 and AX65 at 6.0L.
Is the NOCO GB20 suitable for every vehicle?
No. The manufacturer lists the GB20 for gas engines up to 4.0L and does not provide a diesel-engine limit in the published data. Check your engine type and displacement before buying.
Which model includes an air compressor?
The NOCO Boost Air AX65 is the only model in this published product set identified as including an air compressor and tire inflator.
Closing Recommendation
The NOCO Boost GB70 is the strongest general-purpose recommendation for buyers who need substantial gas and diesel compatibility without paying for the maximum-output GBX155. The GBX155 is better suited to very large engines, while the AX65 is the most useful choice when jump starting and tire inflation belong in one roadside device.
For smaller gas engines and a lower purchase price, the GB20 is the straightforward compact option. Buyers who prioritize quick recharging should consider the GBX45 or another X-series model after confirming the listed engine limits. The right best NOCO jump starter is ultimately the one that matches your engine type, displacement, desired charging speed, and need for added roadside functions.
