NOCO GB40 vs. NOCO GB70: Fast Take
Transportable bounce starters just like the NOCO GB40 and NOCO GB70 present the comfort of on-demand energy when your battery inconveniently dies. You don’t need to fiddle with jumper cables or watch for roadside help, making the GB40 or GB70 supreme for a winter emergency equipment. Past leaping a automobile battery, additional options make both unit a handy software for tenting, looking, and fishing or to have across the farm or store.
- On the subject of on a regular basis autos: It’s arduous to high the 1,000-amp GB40 with its compact design, built-in flashlight, and reasonable $100 price tag. In case your “each day driver” is a typical sedan, crossover, or smaller SUV, the GB40 is the one transportable bounce starter you want.
- On the subject of heavy-use autos: Though the GB40 can deal with fuel engines as much as six liters, the two,000-amp GB70 is extra muscular and provides peace of thoughts if you happen to actually beat the tar out of your automobile. The GB70 is designed for bigger gasoline and diesel vehicles that endure strenuous miles because of heavy use from towing or shifting sizeable payloads. It retails for $200 on Amazon.
I personal a NOCO GB40 and a GB70 and have been pleased with each, save for one minor quirk concerning the GB70. Beneath I’ll evaluate and distinction every unit just a little additional.
Battery & Automobile Compatibility
The NOCO GB40 and GB70 will bounce varied lead-acid batteries, together with moist cell, gel, maintenance-free, enhanced flooded, and absorbed glass mat (AGM) batteries. Each will bounce nearly any RV, marine, four-wheeler, snowmobile, or garden mower battery. The principle distinction between the GB40 and GB70 in battery and automobile compatibility is their total capability.
For instance, the 1,000-amp GB40 will deal with fuel engines as much as six liters and smaller diesel powertrains as much as three liters. The two,000-amp GB70, against this, will bounce gasoline engines as much as eight liters and diesel powertrains as much as six liters in displacement, together with late-model HD vehicles from the Huge Three. That’s to not say it’s unattainable for a GB40 to leap a truck battery (like a half-ton truck) or {that a} GB70 is “too huge” for a sedan battery, extra that every unit has totally different parameters on the utmost it could actually deal with.

Clamps & Cables: Observations & Variations
The GB40 and GB70 have what NOCO calls “precision clamps,” which refers back to the clamp’s spark-proof, crocodile-jaw design. This enables the GB40 and GB70 to soundly and successfully chew down on batteries and terminals of various sizes. One potential draw back is the comparatively quick jumper cables on the GB40 and GB70, which is forgivable since they’re transportable models and might be positioned almost anyplace beneath the hood to succeed in the battery.
One key distinction is how the GB40’s clamps and cables are removable whereas the GB70’s are affixed. The removable cables of the already compact GB40 make it simpler to stow within the microfiber bag NOCO contains with each transportable bounce starter. Nevertheless, the GB70’s connected cables mitigate energy loss throughout a bounce, guaranteeing the unit is well-suited for bigger engines, particularly diesel vehicles.
The potential disadvantage is how the GB70’s cables and precision clamps face away from the flashlight. On the left facet is the charging financial institution, whereas the flashlight is on the fitting facet. The cables and clamps path again and away from the flashlight throughout a bounce and go within the path of the charging financial institution. Ideally, the flashlight and the cables ought to level in the identical path so it’s simpler to see the battery, particularly at night time.

Built-in Flashlight & Charging Financial institution
Built-in into the NOCO GB40 and GB70 is a flashlight with seven totally different modes, together with an SOS beacon and emergency strobe. The constant-on modes have three totally different brightness settings, from greater to decrease. Given its dimension, the GB70 has a brighter 400-lumen flashlight versus the GB40’s 100-lumen flashlight.
In the meantime, the built-in charging banks of both unit can cost a variety of non-public gadgets like telephones, tablets, and e-watches. The principle distinction is how the GB70 comes with an XGC extension twine with a 12V female and male adaptor. Not like the GB40, the GB70 can energy different 12V gadgets, like a transportable tire inflator (we typically use the GB70 to run our Slime inflator).
NOCO GB40 vs. NOCO GB70: Fail-Protected Designs
The perfect similarity between the GB40 and GB70 is the proprietary software program platform inside every unit known as the Battery Administration System, or BMS. As described by NOCO, the BMS is liable for key security options and making a “mistake-proof” transportable bounce starter.
With the BMS, the GB40 and GB70 solely output when the cables are accurately connected to a battery. For instance, if you happen to unintentionally connect with the fallacious terminal (reverse polarity), the models is not going to activate. Equally, if the polarity is right, however one of many clamps is unfastened, the BMS prevents them from delivering energy.
With a correct connection, the white 12V LED gentle will illuminate. The models will make an audible click on, indicating that leaping the battery is protected.
Moderately than hitting all the things they connect with at full blast, the GB40 and GB70 solely ship the juice required by the battery needing a bounce. The models can inform the distinction between a backyard tractor battery and a truck battery and alter energy supply accordingly.
NOCO GB40 vs. NOCO GB70 Verdict
- Reasonably priced & Compact: The 1,000-amp NOCO GB40 is our choose because it accommodates a large swath of on a regular basis autos, each new and gently used. Slim and skinny at beneath 2.5 lbs. with clamps and equipment, the GB40 is straightforward to stow. For those who want a brand new, high-quality transportable bounce starter that received’t break the financial institution, the GB40 is an effective choose for $100 on Amazon.
- Sturdy & Highly effective: As the larger brother, the two,000-amp NOCO GB70 offers extra leaping energy, a brighter flashlight, and a 12V energy outlet. For those who drive an even bigger diesel truck, have a fleet of heavy-use autos, or need a transportable bounce starter with just a little extra muscle, the GB70 is a good value for $200.
