I had my 20v set for over 6 years and I found a few 18v tools in my tool box. I was thinking about getting the 18v adapter to 20v start kit therefore I can get new batteries too. Anyone used this adapter? What you think ?

I don’t have it myself but my uncle has it for his 18v tools and he loves it

Just check to make sure it’s compatible, I believe you can only use slim packs with it as well

I had one for a short while. Unfortunately, it did not work on several of my tools. Specifically the finish nail guns. It did work with four and five amp hour batteries I had and there was a noticeable improvement to the power on the one tool I had that it did work with. It was one of the original units shipped (version 1.0), that had some issues and the supplier requested it be returned, and I have not tested the latest version with larger batteries due to not replacing it, as the not working with nail guns is still an issue with the latest released version.
