    5.0 out of 5 stars A Cost-Effective Upgrade

    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.

    5.0 out of 5 stars works pretty well
    Reviewed in the United States on December 6, 2024
    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.

    4.0 out of 5 stars Performs great, however, difficult to remove device from tool.

    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 could not find replacement batteries for my Dewalt drill and impact driver. These adapters were available, I purchased two of them with batteries and have been using them since the purchase without any problems. They are a bit bulkier than the newer drills and drivers but for my use they work well. One more thing there are no clips or hooks for these adapters so you cannot hang them off your tool belt.
