It does function, but the top doesn’t fit all the tools that are older. So, trying to release it from your tools can be very difficult.

It did what I needed it to do!

It does what it says it does as far as power, but it is very hard to remove it from the tool as the release buttons have to go in much further to release it.

I ordered this item to get my old heavy duty 4 tool set with the hard case that I had bought back in the days that DEWALT was making tools to perform and last for ever. Since I have many newer tools that have small batteries I actually started looking for an item like this many years ago when DEWALT still did not have this item, but the offbrand stuff were too expensive and not tested enough. I recently found this Item and ordered it online. I am happy I did, the shipping was quick and item was securely packed. Then I tried it on all 4 old tools and they all worked fine. I used a 2Ah battery which is the minimum required size and the tools had good enough power, I am certain batteries with more juice than 2Ah would work with even more power. Now installing this device with the battery on the tool is a breeze but taking it off was a bit of challenge or at least for me, I am getting better at it though , it has a trick that I still haven’t fully mastered but I will soon. I do recommend this product just make sure your tool is in the list of the tools that can work with this.

Although there are side clips allowing you to remove the adapter from the tool, it is VERY difficult to remove it. So much so that you probably won’t want to remove it and just buy another. That is what happened to me as I just bought my second one because the first one was too hard to remove.

Adapter fits well, no problem inserting or removing the battery
