Before diving into options, I made sure I clearly understood what the adapter does. Essentially, it allows you to use Milwaukee 18V batteries with tools or chargers that might not originally be compatible with those batteries. This can save money and increase flexibility in your tool setup.
Compatibility with Your Tools and Batteries

Price and Value for Money
Price was definitely a factor. I set a budget but also considered the value I’d get from a reliable adapter. Sometimes spending a bit more upfront on a trusted brand or better construction saved me from headaches later.
