Cordless jobsite fans are not universally compatible with all power tool batteries. Compatibility depends on the brand and battery platform. Most major power tool manufacturers, such as DeWalt, Milwaukee, Makita, and Ryobi, design their cordless fans to work with their specific battery systems. For instance, a DeWalt cordless fan will typically be compatible with DeWalt's 20V MAX or FlexVolt batteries, while a Milwaukee fan will work with their M18 battery system. These manufacturers create ecosystems where their tools and batteries are interchangeable within the same brand and voltage platform. This means that if you own multiple tools from the same brand, you can often use the same batteries across different devices, including fans, drills, saws, and more. However, cross-brand compatibility is generally not supported, meaning a DeWalt battery will not fit a Milwaukee fan, and vice versa. Some fans offer dual power options, allowing them to be powered by both batteries and AC adapters, providing more flexibility. However, even in these cases, the battery compatibility remains brand-specific. In summary, when purchasing a cordless jobsite fan, it is crucial to ensure that it is compatible with the battery system you already own or plan to invest in. This ensures seamless integration into your existing toolset and maximizes the utility of your battery investments. Always check the manufacturer's specifications for compatibility details.
