IT is a snug fit , but it fits securely to both items. It is easy to use. It is perfectly functional. I was worried that it would take up too much space, but so far on my palm sander no problem, you can even mount the dust collector without interference. I have not tried to charge a battery with this adapter mounted, so I can not address charging speed. My only complaint is that the adapter smell really bad, sort of a chemical/plastic/ozone type smell. Hopefully this will dissipate soon. ### ⭐⭐⭐⭐⭐ Great device that saves a lot of money *by on Reviewed in the United States April 28, 2026* Like many people, I have a variety of cordless tools. Over time I decided to stick with mainly one brand, but I still have the odd tool that takes a different battery. The only difference in these battery packs is the connection to the tool, and individual batteries can cost $50 or more. This solves the problem, I can use all my De-Walt batteries on my Milwaukee tool without having to buy a bunch of new batteries. Great Product. It works, fits perfectly and doesn't add much weight or bulk to the tool ### ⭐⭐⭐⭐⭐ Works great on Milwaukee tools *by on Reviewed in the United States April 13, 2026* Worked perfect without any compatibility issues. Fit all my Milwaukee tools perfectly. ## Frequently Bought Together - Adapter for DeWalt to Milwaukee Battery, Aikeec Battery Adapter for DeWalt 18 20V Lithium Battery Convert to for Milwaukee 18V for M18 Battery for Milwaukee for M18 Cordless Power Tool (Adapter only) - ZLWAWAOL MIL18DL Battery Adapter Converter for Milwaukee to Dewalt Battery, for Milwaukee ML18 18V Lithium Batteries Convert to Dewalt's 20V Lithium Batteries,for Dewalt 20V Cordless Tools - ZLWAWAOL DM18M Battery Adapter with USB & Type-C Charging Socket for Dewalt 20V & Milwaukee 18V M18 Lithium Battery Convert to Makita 18V Battery BL1830 BL1840 BL1850 (Adapter Only) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/229663744-battery-adapter-for-dewalt-20v-battery-to-milwaukee-18v-tools](https://www.desertcart.jp/products/229663744-battery-adapter-for-dewalt-20v-battery-to-milwaukee-18v-tools) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-17*
