DEWALT Battery Adapter 18V to 20V, For Drills, Sanders and More, Charger Not Included (DCA1820)

Bringing my old 18V tools back online with this adapter has been awesome. I honestly wish I had known about these years ago. I stopped buying DEWALT tools because the battery platforms kept changing, and it felt like every upgrade meant replacing perfectly good tools. This adapter fixes that problem instantly. It snaps on securely, works flawlessly with my 20V batteries, and makes all my older drills, saws, and lights usable again. It’s one of the coolest and easiest accessories DEWALT has ever offered — simple, effective, and a huge money saver. If you have older 18V tools lying around, this is absolutely worth it.

The DeWalt adapter works great for converting older 18V tools to use the newer 20V batteries. It does exactly what it’s supposed to do, but it will not accept the larger 60V FlexVolt batteries. Still, it’s a very practical solution because it lets you run modern batteries on older DeWalt tools, saving you from having to replace tools that are still perfectly functional but use obsolete battery packs.

I trust this product more than the knock-offs and it keeps all my old 18v tools in business. I have at least 10 older Dewalts in service using these adapters. The one thing about them is that you must pop the battery off because it will drain the battery if left in the adapter for an extended length of time

It's decent battery adapter. My really old 18 volt DeWalt 1/2 impact torque wrench was starting to run sluggish and my Lithium batteries are getting a little slower at full charge (18 volts instead of 21 volts) . Everything is 20 volts now, so I bought this adapter. It makes use of ONE of my 20V max batteries backwards compatible with 5 cordless for 18 volt tools I have. Unfortunately for me it cannot use a DeWalt 6AH battery that came with my 3/8 ratchet kit. The 20V 4AH fits fine, but the 20V 6AH will not fit all the way, unless I cut some plastic on the adapter, which I might do. A simple plastic housing design change and the adapter would have fit easily.

This is perfect for all my 18v tools. I’ve had the cheaper ones, but the Dewalt brand is way better and much more durable.

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.

This works great. It does add a little bulk but if you have a dewalt that uses the older batteries you can't get anyone more this is a great option to make the newer batteries fit.

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.

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

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.

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

Excelente adaptador, le quedó perfecto a un rotomartillo de 18 volts

Is the perfect way to bond old tules with new chargers. I can only recommend it
