great adapter
Works well with my old Dewalt 18v drill I got for free. My battery did not stick in the adapter like some have said.

Works Great On Most 18V DeWalt Power Tools
These adapters are a great way to extend the lives of 18V DeWalt tools by standardizing on the 20V platform. I have an old but reliable set of 18V DeWalt tools and several newer 20V tools and maintaining two different battery platforms was not ideal. These adapters allow all to work with one battery type and one charger. There are two downsides to be aware of. First, the adapters are easy to install but can be difficult to remove so getting one for each tool is best. Also, the adapter increases the overall working size of the tool making it slightly heavier. This is not a huge problem in most cases but the extra length can render a circular saw unusable at some cut depths. This is because the battery may stick out too far to clear the workpiece. I use the 2AH battery to get around this problem on my particular saw. Other models may not require any extra attention.

These work great on my 18v XRP DeWalt tools!
I was really bummed when DeWalt discontinued the 18v XRP line of cordless tools. I have 10 tools and it became impossible to find new batteries for them. I was happily surprised when this converter came out - it works great and allows me to use the 20v batteries which are readily available. Sometimes, it is a bit stick when you try to remove it from the tool and requires a good tug to get it off, but that is a minor issue.

Relatively good product.
The product works as described. I went with Dewalt because I trust the brand. However, it is difficult to remove from the tool. I would have thought that Dewalt would have designed it better but it does work and has extended the life of my 18v tools. I'll probably have to make my own tool to remove the adapter more easily.

Exact fit, easy to use
Worked great. Still got some old Dewalt 18v hanging around. Don't need to throw away good tools

Good investment
These adapters work fine. Easy to convert my 18 volt tools to 20 volts. Other reviewers said they were hard to remove from the tools so I purchased several so I don't need to remove them. The only negative is that leaving batteries connected with the adapter over time seems to drain the battery . I left one connected in my circular saw for several days and the battery was completely drained. Recharged fine.

Makes my old tools work again
I've tried this on all my old dewalt stalk type battery tools. All tools work again with this adaptor now. The price is a bit excessive but if these tools keep working with this adaptor then it's well worth it. The adaptor came in proper plastic retail packaging with instructions so I have no doubt this is a genuine dewalt product

Works as Advertised
Despite a number of negative reviews, I found the adapter easy to insert and remove. It is easier if you take the battery out of the adapter before either inserting or removing the adapter from the tool. I have tested the adapter on a number of my old 18V tools and it works perfectly. Don't forget to remove the battery from the adapter when it is not in use (either on or off a tool) as the adapter contains electronic circuitry which will eventually drain the battery. This is easily achieved if you remove the battery from the adapter before removing from the tool.

transforme parfaitement une batterie NI-cd en Li-on dewalt
Fonctionne très bien m'a permis de remettre en circulation une scie sauteuse et une scie sabre marque Würth (oui il y a 20 ans c'était du dewalt déguisé en Würth). fonctionne également avec des anciennes machines dewalt. seul bémol, non compatible avec les nouvelles batteries Powerstack dewalt, les 2 ergots de chaque côté de l'adaptateur empêche l'engagement de ce type de batterie. après j'ai également acheté une copie chinoise à 20 euros, qui à l'air de fonctionner aussi, mais en tant qu'artisan, j'ai préféré prendre la marque Dewalt (certes 6 fois plus cher), en espérant avoir une garantie de qualité, j'espère que je ne me suis pas trompé, l'avenir me le dira. si ça peut aider certaines personne c'est compatible avec les anciennes machine qui ont les batteries réf.DW9095, DE9095 et certainement d'autres références que je ne connais pas. Merci d'avoir pris le temps de me lire. Gaël

Justo lo que buscaba
Excelente adaptador. Justo lo que buscaba ya que tenía herramientas que no utilizaba por las baterías anteriores y ya no cargaban. Con este adaptador hice revivir mis herramientas. Lo recomiendo
