This significant difference of 2,500 RPM can be crucial for users who require faster cutting or grinding capabilities.
While both grinders feature three adjustable speeds, the FULLYEA offers a broader range, with settings of 12,000 RPM, 9,000 RPM, and 6,000 RPM. In comparison, the AOBEN's settings provide flexibility but do not reach the higher performance levels of its competitor. This performance edge may make the FULLYEA more appealing for those who prioritize speed in their projects.
Battery and Runtime
Battery life is a critical factor when choosing a cordless grinder, and both models come with two 4.0Ah batteries. This similar capacity ensures that users of both grinders can enjoy extended runtimes. However, the actual performance may vary based on the motor's efficiency and the tasks being performed.
The AOBEN grinder is designed for a variety of applications, while the FULLYEA offers a faster operational speed. Depending on the user's needs, the runtime may be impacted by the tasks performed at higher speeds. Both grinders eliminate the limitations of power cords, providing greater flexibility for use in various locations.

On the other hand, the FULLYEA grinder is also designed for ease of use, with a spindle lock feature that allows for quicker disc changes.

For budget-conscious consumers, the price difference is significant and may influence purchasing decisions.
Despite the price advantage of the FULLYEA, potential buyers should consider the performance differences before making a decision. While the lower price is attractive, the AOBEN offers features that may justify its higher cost for those seeking specific functionalities.
Which should you buy?
Choosing between the AOBEN Cordless Angle Grinder and the FULLYEA Cordless Angle Grinder ultimately depends on your specific needs and budget. If you prioritize speed and a lower price point, the FULLYEA at $49.99 is a compelling option, especially with its maximum speed of 12,000 RPM. However, if you seek a grinder with a focus on comfort, control, and additional safety features, the AOBEN at $79.99 may be worth the investment. Both tools provide excellent performance, but your choice should align with your project requirements and personal preferences.
