MIL18DL Battery Adapter Converter for Milwaukee to Dewalt Battery, for Milwaukee M18 18V Lithium Battery Convert to Dewalt 20V Lithium Battery,for Dewalt 20V Cordless Tools

This works great!

Worked great for Dewalt power tools except my Dewalt Weed eater. . The M18 8.0 Milwaukee battery with this adapter hits the unit and wont fit . Would probably work i am sure, if it fit

Perfect convertor for Milwaukee batteries to DeWalt tools, saved me a ton of money!

This is for the MIL18DL (Milwaukee Batteries to DeWalt Tool adapter). The adapter itself isn't bad, it works and will fit your DeWalt tools. I can't speak for the Ryobi version of this adapter as the pics show 2 parallel 18AWG wires for a total ampacity of 32A @ 90A or 36A @ 105C (don't know what the wire insulation is rated for in that adapter). HOWEVER! I took it apart because I've never purchased from this seller before and found that the wiring is only 1x18AWG and 90C rated. This puts the max amperage for this adapter at 16A, maybe 18A if you get a version with 105C rated wiring insulation. This is opposed to other adapters which are running 14 or 12AWG, which is 25A or 30A @ 90C and 33A or 45A @ 105C. The 18AWG in this adapter isn't even affixed to the blades very well, some strands weren't soldered/welded on which is going to reduce its ability to carry current and create more heat. I tried replacing the wire with 10AWG 200C rated wire for a max rating of 75A, but the prongs would not play nicely and ended up carrying the heat to the plastic, deforming it, vs. affixing the wire. In short, use this only if you don't plan to use demanding tools with it because the tool is going to either run subpar OR this adapter is gonna get hot. P.S. For some reason it says, "Supports fast charging" on the side but just like every other adapter, it states "Do not charge using adapter." Not sure what genius put that one in, but guys, never charge using an adapter regardless of what it says.

If you're looking for a battery adapter to use Milwaukee M18 batteries with a Dewalt 20V tool, this will work. However, one thing to note is that this adapter reverses the battery orientation. In some cases that may cause ergonomic or tool usability issues. As an example, I was using this on a cordless non-name brand brushless tool which runs the 4.5" surface conditioning drums. The Milwaukee battery hung down lower than if using a Dewalt battery on the tool when using this adapter. I looked again on Amazon and found one alternate adapter which preserves the proper battery orientation (ASIN: B0FJD4B9DS). That one isn't built quality as well as this adapter, but it keeps the battery in the right spot and is working fine. Does this one work? Yes, but I think there are better alternatives out there which doesn't impact certain cordless tools from being used effectively with a Milwaukee battery. I didn't notice this when purchasing, so this is why I decided to write the review to educate others. In the first photo you'll see this adapter on the tool with a Milwaukee M18 Forge battery to make my point. The second photo is the alterative adapter, and you can see how it affects the clearance of certain tools. On a drill, this probably wouldn't be a big deal, but on a grinder, it may be something worth paying attention to.
