Dewalt adapter kit

Finding the best Dewalt adapter kit and dewalt battery adapter kit for 18v tools can be hard if you’re unaware of what features to look for especially that there are so many of them to find around. For this reason, we’ve put up a guide highlighting the top dewalt 18v to 20v adapter kit review in the category.

Our team has researched and reviewed these products to help you come up with a better decision. 

DeWalt has announced the launch of the Dewalt 20V Max Battery Adapter. A lot of 18V cordless tool users will be happy with this, especially those who heavily invested in DeWalt’s 18V tool system. With this adapter, it will be easier for 18V users to experience higher capacity batteries with lithium-ion technology. Stepping up from nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries, lithium-ion boasts plenty of advantages. Lithium-ion batteries have relatively low self-discharge, are lightweight, and have higher density energy making it the new standard battery for power tools these days.

“Consumers and pros that aren’t heavy users should be able to expect 5 or more years out of their cordless tools. As technology has left NiCd and NiMH behind, lithium-ion is the dominant standard in the industry. We wondered if there would ever be a solution to bring DeWalt’s stick style 18V batteries into the lithium-ion technology with the change to slide style packs on the 20V Max system. The DeWalt 20V Max Battery Adapter makes that happen.”

The DeWalt 20V Max Battery Adapter will allow most of DeWalt’s 18V cordless tools to function and operate with DeWalt’s 20V Max Lithium-Ion batteries. It’s going to add some height to the tool as well as a little bit of weight. However, moving to lithium-ion chemistry is worth the trade off. The new adapter is compatible with six 20V Max battery packs plus two Bluetooth enabled batteries, allowing users to choose the optimal battery for a the application at hand.

What is the Compatibility of the DeWalt DCA1820 Battery Adapter?

The DW Adapter comes with 6 battery options, which include:

71VubbsWaBL._SL1000_ Dewalt Battery Adapter Review
  1. 3 Ah
  2. 1.5 Ah
  3. 2.0 Ah XR
  4. 3.0 Ah
  5. 4.0 Ah XR
  6. 5.0 Ah XR

You should note that the Bluetooth batteries 2.0 Ah and 4.0 Ah can also be used with Dewalt’s 18v tools, so this definitely offers a little extra compatibility for you, as well.

Of course, there is also another reason to smile about this, because the reality is that your tooth won’t be blue at all—and neither will you! Isn’t that great? (but not as great as my jokes, right?).


  • The battery and charger don’t force you to buy individually or as a set—they can be purchased separately but can also be purchased as a kit. If you already have a usable charger (or battery) then you needn’t fork over the dough for these things. Today, many tools have the “baretool” setup and that more or less forces us to buy each item one-by-one which is expensive, while others only come in a kit and that requires us to spend more on something we don’t need. No problem with that here.
  • Dewalt’s battery adapter is quite variable so it can be and is actually designed to be used with a wide range of battery-operated tools within the popular and highly-rated De Walt arsenal.
  • It allows for full use of battery sizes up to 20V, even when combined and used with DeWalt 18v tools.
  • A excellent 3 year warranty is provided and even includes free service for 1 year after the purchase, which is quite impressive for something as affordable as it is. It is also readily available and value-priced at online shopping portals such as Amazon.
  • It is very light weight due to the design of both the material and the operating angle, which balances the battery quite nicely. The cool thing is that you can literally get 20v power usage with an 18v weight. Just imagine how jealous your friends will be when they see you whirring away faster than they are with their new tools. Your dog may not understand the value of this (unless he’s Old Yeller of course), but rest assured, your friends will.
  • The design allows for a slim and unobtrusive profile (see image above) which means that it doesn’t add much to your tool in the way of bulk, awkwardness, or clumsiness. When you factor this into the light weight I mentioned above, then I think you’ll really appreciate these aspects when you’re busy using your drill and aren’t bothered by fatigue or handling issues.


  • One of the sad truths is that this battery adapter cannot be used with the 18V XRP battery charger. Yes, sadly, it’s true: not all things are perfect, not even the DeWalt power tool lineup and matching adapter :(.

  • The DCA1820 battery adapter doesn’t work with chargers of various previous models. This is, to me, a somewhat small but VERY important point for  you to remember. It’s quite possible for you to place an order for one of these little gems and upon its arrival, realizing that it’s not compatible with the current charger that you have in-hand. A simple and fast check in the Death Star Plans — or in the product specs — will tell you quickly if this is truly the droid–err, charger that you seek.
  • A separate charger is actually required to work with this DeWalt 18v to 20v adapter. It seems like a no-brainer, but after I looked into other people who ordered it online, there have actually been some people to order it without looking closely enough at the product details (or maybe just not thinking about it). As a result, I think that it’s important for you that I note that this is an ADAPTER ONLY, and not an actual charger itself. In other words, it connects to the tool and allows you to attach the battery, but does not itself connect to any power outlet nor charge the battery. If you don’t have a working charger, then you’ll essentially either need to buy one or perhaps “permanently” borrow one from your neighbor (we don’t recommend the fiver-finger discount). If you are like my brother was back when we were teenagers, then you could just take it from a close friend or family member and later pretend that it was always yours!
  • I’ve already mentioned this before, but I think it’s important to reiterate that it is definitely NOT compatible with every single portable DeWalt tool ever made. Again, this may seem obvious to most of you—not to mention the fact that we already stated it above, and clearly I might add—but for those who may have missed it or have not retained or remembered this point, please, PLEASE be sure to check compatibility with your tools BEFORE placing an order for this adapter. The little bit of time you spend now could definitely save you time and frustration later, and possibly money, to boot. DOUBLE-CHECK THE COMPATIBILITY!
  • Premium or high capacity batteries are just not friends with this adapter so, as always, read the fine print. Again, it has a specific range of tools and batteries of which it is compatible with and this does not include the higher-capacity batteries, so keep that in mind when ordering. It’s sort of like when a new kid walks up to the rich snobs on the playground and asks “Hey, what’s up?” The immediate result will most likely be dumbfounded silence, followed a whole lot of frustration. A little foreknowledge goes a long way!

Final Word

The short and long of it is that this is a very straight-forward product with a clear function: it enables the use of both 18 and 20-volt batteries in certain older cordless DeWalt power tools. The only main questions left to get solid answers to are “How good is it? Is the cost fair?” and “How compatible is it with the various tools?”

In short, this is what I believe:

  1. It’s definitely darn good and worthy of the quality that DeWalt has built for most all of their line of tools. After looking up what others are saying, I found that customers who’ve purchased these have done so by the droves and left hundreds, if not thousands, of near-perfect ratings. That’s an excellent indicator from right out of the gate.
  2. The price point is excellent. Actually, the cost was a bit higher until more recently, and the price has actually dropped dramatically, much to my surprise. As of the writing of this article—September 1st, 2017—the adapter alone costs merely $35 online, which is not necessarily a permanent price but definitely palatable. That is an amazing value, considering how it has the power to bring our old tools back from an early grave.
  3. The compatibility isn’t “perfect,” but then again, it’s hard to actually see how it could be. The focus of this particular adapter is to work with a certain set or range of cordless tools—which happen to be the most popular ones–and that makes sense. With that in mind, I have no big beef about its compatibility and, given the new pricing structure, find that it is far more than a bargain.
