When your motorcycle battery dies unexpectedly, a compact and dependable jump starter can turn a roadside problem into a much easier recovery. The right option should fit your luggage, work with your motorcycle’s battery system, provide suitable starting power, and include safety features that make connections easier when you are away from home.

This guide compares three portable NOCO jump starters for motorcycle use. The GB20 is the most motorcycle-focused option, the GB40 adds useful multi-vehicle flexibility, and the GB70 provides substantially more reserve for riders who also want to cover larger vehicles.

Top Picks

Selection Criteria

For motorcycle use, starting power is only part of the buying decision. Portability, battery compatibility, clamp access, safety features, storage requirements, and ease of recharging the jump starter can matter just as much. A very large jump pack may offer impressive peak output while being less convenient to carry on a bike.

We therefore prioritized practical motorcycle use first, followed by versatility for riders who also own cars, trucks, ATVs, RVs, boats, or other compatible 12V vehicles. Spark protection, reverse-polarity protection, weather-resistant construction, integrated lighting, USB device power, portability, and clear manufacturer specifications were also considered.

NOCO GB20

The NOCO GB20 is the most motorcycle-oriented option in this group because it combines a 500A peak starting rating with a relatively compact body. It is designed for compatible 12V lead-acid batteries and gasoline engines up to 4.0 liters, giving it ample manufacturer-rated engine coverage for motorcycle-first use without moving into the size and weight of a heavy-duty jump pack.

Its IP65-rated enclosure, spark-proof design, reverse-polarity protection, 100-lumen flashlight, and USB device-charging output make it useful as a dedicated roadside emergency tool. The internal lithium-ion battery is rated at 24Wh, and the current manufacturer specification lists the complete unit at about 2.1 lb.

Why You’ll Like It

• 500A peak output in the most motorcycle-focused package of these three choices

• Spark-proof and reverse-polarity protection help reduce common connection mistakes during normal operation
• 100-lumen multi-mode light helps with nighttime roadside work
• USB power output can provide backup power for compatible personal devices

Who Should Buy This?

Choose the GB20 if your main goal is carrying a jump starter on a motorcycle and you want to minimize size and weight while retaining useful emergency features.

Who Should Avoid This?

Skip it if you primarily need to jump diesel vehicles or want substantially more reserve for larger multi-vehicle duties. Also confirm compatibility first if your motorcycle does not use a conventional 12V lead-acid starting battery.

NOCO GB40

The NOCO GB40 is the stronger all-round choice when you want one portable jump starter for a motorcycle and other household vehicles. It delivers 1000A peak output and is designed for compatible 12V lead-acid batteries, gasoline engines up to 6.0 liters, and diesel engines up to 3.0 liters.

At about 2.45 lb according to the current manufacturer specification, it remains portable but gives you more starting capability than the GB20. You also get an IP65-rated enclosure, spark-proof and reverse-polarity protection, a 100-lumen multi-mode flashlight, and USB device charging.

Why You’ll Like It

• 1000A peak output provides more multi-vehicle flexibility than the GB20
• Still portable enough for riders who can spare a little more luggage weight
• Can serve as one compatible emergency starter for motorcycles and many passenger vehicles
• Integrated spark-proof and polarity-protection circuitry helps reduce connection mistakes during normal operation
• USB power and a built-in flashlight add useful roadside functions

Who Should Buy This?

The GB40 makes the most sense if you want one jump starter for your motorcycle, car, SUV, or another compatible 12V vehicle instead of carrying a motorcycle-focused unit only.

Who Should Avoid This?

If minimizing motorcycle luggage weight is your priority, the smaller GB20 is the more focused choice. Riders needing substantially more reserve for larger vehicles may prefer the GB70.

Ease Of Use

Durability

The GB40 uses a rubberized over-mold and an IP65-rated enclosure with its ports properly closed. It carries a one-year limited warranty and remains reasonably portable despite its higher starting rating.

Key Benefits

• 1000A peak output for broader multi-vehicle use

NOCO GB70

The NOCO GB70 moves into high-reserve territory. Its 2000A peak rating is intended for compatible 12V lead-acid systems and engines up to 8.0 liters gasoline or 6.0 liters diesel. A typical motorcycle does not need this level of engine coverage; the main benefit is having one powerful jump pack that can serve your motorcycle and substantially larger vehicles.

The trade-off is portability. At about 4.18 lb according to the current manufacturer specification, the GB70 is considerably heavier than the GB20 or GB40. In return, you get a 56Wh internal battery, a manufacturer claim of up to 40 jump starts under suitable conditions, a 400-lumen flashlight, IP65-rated construction, USB device charging, and additional 12V power capability.

Why You’ll Like It

• 2000A peak output offers substantial reserve for multi-vehicle households
• 56Wh internal battery provides more stored energy than the smaller models
• 400-lumen flashlight is useful for dark roadside situations
• Well suited to riders who also want compatible coverage for cars, trucks, RVs, boats, or similar vehicles
• Spark-proof and reverse-polarity protection remain built in during normal operation

Who Should Buy This?

Choose the GB70 if you own a motorcycle but also want a high-capacity starter for substantially larger compatible vehicles, or if carrying the lightest possible motorcycle kit is not your main priority.

Who Should Avoid This?

Most riders buying solely for motorcycle use do not need this much engine coverage or stored capacity. The GB20 or GB40 is easier to justify when luggage space and weight matter.

Ease Of Use

Durability

The GB70 has a rubberized over-mold and IP65-rated enclosure with its ports properly closed. Its larger body and stronger output make it better suited to multi-vehicle emergency duty than to minimalist motorcycle packing. It carries a one-year limited warranty.

Key Benefits

• 2000A peak starting output
• 56Wh internal lithium-ion battery
• Manufacturer-rated for up to 40 jump starts under suitable conditions
• 400-lumen multi-mode flashlight
• UltraSafe spark-proof and reverse-polarity protection during normal operation

How To Choose A Motorcycle Jump Starter

Start With Your Battery Type

Do not choose a jump starter only by peak amps. First confirm your motorcycle’s battery voltage and chemistry. The GB20, GB40, and GB70 are designed for compatible 12V lead-acid batteries. If your bike uses lithium, LiFePO4, or another battery chemistry, do not assume compatibility; follow the instructions from the motorcycle, battery, and jump-starter manufacturers.

Consider Portability

A jump starter is only useful on a trip if you are willing and able to carry it. Riders with small saddlebags or under-seat storage should place more weight on compact size and lower weight. Multi-vehicle owners may accept a larger unit in exchange for greater stored energy and broader engine coverage.

Understand Peak Amps

Higher peak output does not automatically make a jump starter better for a motorcycle. A smaller compatible unit can be easier to pack while still covering your intended motorcycle use. Larger units become more attractive when you also want one jump starter for cars, trucks, RVs, boats, or other compatible vehicles.

Check Clamp Access

Motorcycle batteries can be harder to reach than car batteries. Before buying, consider where your battery terminals or approved jump points are located and whether the supplied clamps can connect securely without touching surrounding metal parts. Always follow the motorcycle and jump-starter manuals for the correct connection points and sequence.

Do Not Ignore Storage And Recharging

A portable jump starter needs to be charged before you need it. Check its state of charge before long trips, follow the manufacturer’s recharge guidance, and store it within the temperature range stated in its manual. A discharged jump pack stored in your luggage will not provide the emergency backup you bought it for.

FAQ

Which Jump Starter Suits My Motorcycle?

Start by confirming your motorcycle’s battery voltage and chemistry. Then choose the smallest compatible jump starter that provides suitable starting capability and fits your available luggage space. The GB20 is the most motorcycle-focused option here, the GB40 gives you greater multi-vehicle flexibility, and the GB70 is aimed at riders who also want substantial capacity for larger vehicles.

Can I Use A Jump Starter On A Motorcycle With A Lithium Battery?

Do not assume compatibility. The GB20, GB40, and GB70 are specified for compatible 12V lead-acid batteries. If your motorcycle uses a lithium or LiFePO4 starter battery, follow the motorcycle, battery, and jump-starter manufacturers’ instructions before making a connection.

How Do I Use A Jump Starter Safely?

Read the manual for both the motorcycle and the specific jump starter before connecting it. Confirm voltage and battery compatibility, switch off unnecessary electrical loads, and connect the clamps to the approved points in the sequence specified by the manufacturers. Keep the clamps separated, keep connections dry, and stay clear of moving or hot engine components.

After the engine starts, disconnect the jump starter according to its manual. Do not activate Manual Override casually. NOCO states that this function disables normal safety protection and should only be used when the battery voltage is too low for the jump starter’s normal detection system.

Does A Motorcycle Need A 2000A Jump Starter?

Not simply because it is a motorcycle. The GB70’s main advantage here is multi-vehicle versatility rather than a normal motorcycle requiring 2000A. If your priority is motorcycle portability, the GB20 or GB40 is generally the more practical choice. The GB70 becomes more attractive when you also want to cover substantially larger compatible vehicles.

How Should I Maintain And Store A Jump Starter?

Store the unit in a dry location within the temperature range stated by its manufacturer. Check its charge before long rides and recharge it according to the schedule or guidance in the manual. Inspect the clamps, cables, housing, and charging ports periodically for damage or contamination.

What Is The Difference Between The GB20, GB40, And GB70?

The main differences are starting output, engine coverage, stored energy, weight, and portability. The GB20 is the most motorcycle-focused at 500A peak. The GB40 increases output to 1000A and adds broader gasoline and diesel vehicle coverage while staying relatively portable. The GB70 increases output to 2000A and uses a larger 56Wh internal battery, but it is considerably heavier and is best justified when larger vehicles are also part of your emergency-preparedness needs.

Quick Comparison

Wrapping Up

If you mainly want a compact emergency jump starter for your motorcycle, the NOCO GB20 is the most focused choice in this group. It keeps size and weight reasonable while providing the key safety and roadside features most motorcycle-first buyers are likely to value.

If you want one portable starter that can cover your motorcycle and a wider range of everyday vehicles, the NOCO GB40 offers the strongest middle ground between portability and starting capability. It is the most versatile choice here for riders who also want coverage for common passenger vehicles.

The NOCO GB70 is better suited to riders who also own substantially larger compatible vehicles and are willing to carry a heavier unit. Its 2000A rating and 56Wh internal battery provide significantly more reserve, but that extra capability is harder to justify when motorcycle portability is your only concern.
