Noco Gb50 Vs Gb70 Buying Guide
Portability and Size
When considering portability, the GB50 generally holds an advantage due to its more compact and lightweight design. This makes it an excellent choice for users who prioritize keeping it easily accessible in a glove compartment, backpack, or even a motorcycle saddlebag. Its smaller footprint means it takes up less space, which is a significant factor for those with limited storage.
Conversely, the GB70, while still relatively portable, is noticeably larger and heavier. This increased size is a direct result of its higher battery capacity and more robust internal components. If you plan on using it for more demanding jump-starting situations or for powering multiple devices, the slightly less portable GB70 might still be a viable option if its power output is a priority.

Power Output and Cranking Amps
The core difference lies in their power output. The GB70 boasts significantly higher cranking amps compared to the GB50. This translates to a greater ability to start larger engines, including those found in trucks, SUVs, and diesel vehicles. If your primary concern is ensuring you can jump-start a wider range of vehicles, especially those with larger displacement engines or in colder conditions, the GB70’s superior power is a clear benefit.
The GB50 is perfectly capable of jump-starting most passenger cars, motorcycles, and smaller engines. Its 1000 peak amps are more than sufficient for typical roadside emergencies. For the average car owner who rarely encounters exceptionally challenging starting conditions, the GB50’s power output is more than adequate, offering a good balance between performance and price.
Battery Capacity and Longevity
Battery capacity is a key differentiator. The GB70, with its larger internal battery, can provide more jump-starts on a single charge and is also more capable of holding a charge for extended periods. This makes it a more reliable option for emergency preparedness or for users who might not have frequent access to a charging source. Its higher capacity also allows for more power delivery over a longer duration.
The GB50 offers a respectable battery capacity that will comfortably handle multiple jump-starts for typical vehicles. While it may not match the sheer number of jump-starts the GB70 can provide, it still offers excellent longevity for its size and intended use. For most users, the GB50’s capacity is more than sufficient for their needs, providing peace of mind. (See Also: Pixel 6a Vs Iphone 12 )

Frequently Asked Questions
Which is better for a diesel truck?
For a diesel truck, the Noco GB70 is the clear choice. Diesel engines require significantly more power to crank, especially in cold weather. The GB70’s higher cranking amps are specifically designed to handle the demands of larger diesel engines, ensuring a reliable jump-start when you need it most. The GB50 may struggle or be unable to start a diesel.
Can the GB50 jump-start a V8 engine?
Yes, the Noco GB50 can jump-start most V8 engines in gasoline vehicles. Its 1000 peak amps are sufficient for the typical starting requirements of a V8. However, if the V8 is in a larger truck or SUV, or if the engine is cold or has a weak battery, the GB70 would provide a more robust and confident jump-start. (See Also: Galaxy Watch 6 Vs Active 2 )
How long does it take to charge the GB70?
The charging time for the Noco GB70 can vary depending on the charging method. Using a standard USB charger, it might take around 6-8 hours to reach a full charge. However, utilizing a higher-output charger or the included 12V car charger can significantly reduce this time, potentially to around 3-5 hours for a complete recharge.
What is the difference in battery capacity?
The primary difference in battery capacity is that the GB70 has a significantly larger internal lithium-ion battery.
