This adaptor is fantastic. Fits perfectly, snug, and tight. Doesn't wiggle around, won't come loose. Now you can use new generation of batteries on older tools that are perfectly fine, so you don't have to retire older tools or try to keep different battery types around. DEFINITELY WORTH THE COST! More pricey than the generics out there, but probably much better quality and much tighter fit also.

Dude I can't believe this is all I needed. Fit old XLR drills' firm factor perfectly. No problems, all my new DeWalt 20v batteries operate all the old 18v dolls columnar form-factors perfectly. I'm thinking of getting a couple more for friends or to have around on hand.

I didn’t want to buy all new tools and this can get me by for a while. Battery life carries over pretty good. It’s easy to switch between tools and it saves a lot of money on new tools.

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

this is the second one of these i have purchased. they work really well, and there are only a couple of things that you can't use with them. there are a few batteries that are not compatible, and there are a couple of tools that are not compatible. luckily, i only have one tool that can't be used. i'll just have to keep a couple of NiCd batteries around for that. there is one anomaly that i have noticed. on some work lights, the output is not steady. it dims a little, for a very short time, at constant intervals. i suspect it is a combination of circuitry in the adapter and the type of bulb in the work light (not LED). in any case, it's a great way to use new batteries on old tools.

takes a great deal of force to pinch both levers on either side simultaneously to remove the adapter from the tool. However. performs great as expected.

I purchased the DEWALT 18v to 20v Adapter (DCA1820) to breathe new life into my trusty old 18v Dewalt Jigsaw, and here's my take:Fit and Compatibility:The adapter fit my 18v tool like a glove. There was no fuss or need for any modifications. It snapped into place securely, ensuring that my jigsaw could now benefit from the newer 20v lithium-ion batteries.Performance:Over the past few months, this adapter has performed flawlessly. There's been no noticeable power loss or any issues with battery life. It maintains the charge well, and the jigsaw operates just as effectively as it did with its original battery setup.Value for Money:Now, regarding the price - yes, it does feel a bit steep for what essentially is a piece of molded plastic with some electrical contacts. However, when you weigh it against the cost of purchasing an entirely new tool or a set of batteries specific to the 18v platform, this adapter comes out as a clear winner in terms of cost savings.

Durable, well-made adapter with a few caveats:1) The active electronics in this adapter generate a once-per-second flicker on 18V worklights, e.g. the DW919, using either an LED bulb or the original Xenon bulb. Off-brand copycat adapters with only wires in them do not flicker.1a) Remove your battery from this adapter during storage to prevent the adapter electronics from slowly discharging your battery.2) The 2 tabs you see protruding forward PREVENT installation of the following batteries: 5Ah PowerStack DCBP520, 6Ah XR DCB206, 8Ah XR DCB208, 10Ah XR DCB210. The largest batteries that may install on this adapter are the smaller XR's: 5Ah DCB205 and 4Ah DCB204.2a) The 2 large 'compact' batteries 4Ah DCB240 / 3Ah DCB230 have a large footprint which extends forward 0.7" further than other batteries and could interfere on a circular saw, e.g. DC390.2b) The XR batteries that do fit this adapter (4Ah DCB204 and 5Ah DCB205) reduce max cut depth on the DC390 circular saw from 2-1/8" to 1-7/8" for carbide-tipped blade. Bevel cuts above 22 degrees are unaffected as the battery rocks up out of the way - so it can still 45 dimensional 2" lumber.3) As others have stated, the first time clicking this adapter into a tool it is VERY stiff, and nearly impossible to remove - you need to start to disengage one side, and hold that side partially open while disengaging the other side... It gets dramatically easier after a few install / removal cycles.

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.

Works great with my old XRP Nicad drill. Feels like got more power too with Lithium Batts but could just be imagination playing tricks again. But definitely benefiting from longer run time especially with 5.0AH battery. No probs inserting into drill or disengaging. What I would say probably an obvious downside is size increase of tool with adapter fitted.
