Key differences between Noco GB40 and Stanley J5C09Noco GB40 Vs Stanley J5C09

  • Battery ampere capacity

The manufacturers of both jump starters have not specified the internal ampere capacity. The two jump starters support up to 1000 amperes output range; however, there is a slight difference between them where Noco GB40 can jump-start car battery 20 times while charging once while a Stanley can perform approximately five jump-starts.

A Noco GB40 jump starter has a larger internal battery capacity when compared to the Stanley J5C09 jump starter.

  • The number of jump-starts in a single charge

The number of jump-starts in a single charge for both Noco GB40 and Stanley J5C09 is recommended differently. For example, a NICO jump starter can jump start a dead battery up to approximately 18 to 20 jump starts before the car battery is recharged. In contrast, you can jump-start the car battery using a Stanley jump starter only four times before you restore the vehicle battery.

Most people using Stanley jump prefer examining the battery’s condition and identifying why the car battery is failing to start or is flat. The jump starter is still charging if they fail to fix the battery since the jump starter can only jump-start the battery for a few times. When purchasing a jump starter for your car, consider the number of jump-starts the jump starter can support if the battery flattens while travelling.

  • Design and performance

The two jump starters have different features, although they function the same. The Noco GB40 allows the user to jump start the car and charge other devices such as smartphones since it contains USB ports. Also, the Noco GB40 jump starter has a power pack only and has a 100 lumen LED light that helps at night mainly.

When compared to Stanley J5C09, the features differ. For instance, the jump starter allows power transmission from the power supply source to the battery. Also, it provides light, just like the Noco GB40. Finally, the jump starter has a unique built-in compressor that jump-starts your tires by pumping them, bringing them to correct functioning.

  • Charging methods

Each jump starter has different charging methods. For Stanley J5C09, they can be charged through the main switch or a charger with 12 voltages. The ability of the jump starter to be charged by 12 voltages is advantageous since you may keep charging the battery while driving.

Compared to Noco GB40, the jump starter is charged via USB only, and it is challenging to keep driving along with the car battery charging. Therefore, choose the best jump starter with the best charging method that suits your preference.

Standard features between Noco GB40 and Stanley J5C09Standard features between Noco GB40 and Stanley J5C09

Jumps starters perform the same function of bringing dead or failing batteries to correct functioning allowing the vehicle to run normally. The jump starts have some common features that are discussed below.

  • USB ports

Both Noco GB40 and Stanley J5C09 have USB ports. The ports provide connectivity to other devices that use USBs, such as tablets and smartphones. If the jump starter lacks US ports, it is advisable to consider choosing one with the ports to allow an individual to establish a connection that can jump-start the battery bringing it to correct functioning.

  • Polarity

The two jump starters have a safety feature of protecting the car battery from any reverse polarity if the battery is connected to the power supply source. Reverse polarity is a situation where the car receptacle is connected backwards instead of in front. Reverse polarity usually occurs when either the black or red wire is connected to different cables.

  • Ampere range

Unlike other jump starters, both Noco GB40 and Stanley J5C09 support high amperes. For instance, they can support up to approximately 1000A maximum output range. Therefore, they can charge a dead battery if possible due to their maximum amperage output.

  • LED lights

LED lights are vital, especially at night. Both Noco GB40 and Stanley J5C09 jump starters have built-in LED lights used for working at night.

  • Battery indicators

The battery level indicator is essential in that it indicates the level of charge remaining and how long it can last before the battery drains power ultimately. The battery level indicator feature is standard for Noco GB40 and Stanley J5C09.
