Dewalt 20V MAX Lithium-Ion Battery Adapter for 18V Cordless
This adapter allows me to use the most advanced 20v Lithium ion Dewalt batteries for all my older 18V Dewalt tools that were configured with the older style Nicad batteries that inserted into the tool. The Ni-Cad batteries would loose their charge over time. I don't have that issue w/the Lithium ion batteries. To use it, simply insert the adapter into the tool, then slide the 20v battery into the adapter. Thank you Dewalt for this product.

This worked as advertised on all my 18v tools. Saved me from having to upgrade everything. It's lightweight. Makes tools goofy looking but gets the job done.

This adapter is awesome and works great on my 18 volt tools
This adapter using the 20 volt battery really extends the work time on my 18 volt drills and lights. It also works great on my saws all and again the run time is really extended. I would buy again and again, it makes that much difference in the performance of my equipment

Finally a tool vendor takes care of loyal customers
Allows customers who own both 18v and 20v Dewalt tools to use a single 20v battery to drive both tools. Nice to have a vendor who recognizes customers needs and responds. Makes me a loyal Dewalt customer. I used to buy Craftsman battery powered tools for years but every time they came out with a new tool, the battery was different.

The best thing since sliced bread!
Dewalt has caught a lot flack from a lot of reviewers, such as hard to remove, it does not work on all tools. I am just glad that one company has made an effort to help out the many owners of the 18 volt line who invested heavily in the 18 volt line such as me. All of my 18 volt tools are in perfect working order except for my trim saw, which the bolt that you tighten the saw depth with has stripped out and no longer holds the saw up in a position for thinner depth cuts. Other than that, the adapter works just as it should, it is light and works to my satisfaction!

About time!
About time. A lot of people and contractors have a lot of money tied up in 18V tools- this make the transition to the 20V's a lot smoother. Bought the adapters to use on my old 18V's, but all the new tools and batteries I will buy will be the 20V, thanks to having an adaptor

Love the 20v battery adapter for the 18v tools!
Easy to use and adds power and longevity to cordless saws, like the circular saw and the "saws all" saw. Actually like the 20v battery better on the 18v impact driver than on the 20v impact driver because the max rpms on the 18v are lower than the max rpms in the 20v impact driver. Seems like it will be durable. The 20v lithium ion batteries hold a charge longer than the 18 v no cad, so this adaptor will allow us to use existing tools for years to come if they phase out 18v no cad batteries

Fabuloso
True this works with only the small 20V LI-ON battery but does it ever work and so far with Drills, Saws, Recip saws,Jig saws the works. Typical DeWalt Quality and functionality. Folks, Even the smaller batteries last a long time and with LI-ON even longer plus you get 2. This device works well for folks who have all the hurting hands and finger problems that come with age advancement and sometimes it is difficult to squeeze those prongs on the 18 volt post battery so now on you favorite tool no more pain plus the post unit is also available as a separate unit if extras are needed

The description and tech specs says it will work only with the 200 and 203 series batteries but I have the 204 series batteries, will this product work the newer series of batteries?
DIYer on Aug 4, 2016
BEST ANSWER: I use this for my 203 series battery and it works fine.
I would think if it were more versatile they would certainly take advantage of the wider customer baseby including the 204 series in their description.
