DM18M Battery Adapter with USB & Type-C Charging Socket Compatible with Dewalt 20V & Milwaukee 18V Batteries, Convert to Makita 18V Batteries (Not Made in Milwaukee,Dewalt, or Makita)

This 18M Battery Adapter is basically the United Nations of power tools. If you’ve got DeWalt 20V or Milwaukee 18V batteries and Makita 18V tools, this little genius makes them all play nicely together. First off, the fit is solid and secure. My DeWalt 20V and Milwaukee 18V batteries lock in firmly, and the adapter connects cleanly to my Makita 18V tools without any wiggle or sketchy movement. It feels sturdy and workshop ready, not like some flimsy plastic experiment. Performance-wise? Impressive. My Makita tools run smoothly and consistently with both DeWalt and Milwaukee batteries. No power drops, no weird behavior just reliable performance like you’d expect. The bonus USB and Type-C charging ports are the real surprise win. I can charge my phone, headphones, or work light straight from my tool battery. It’s perfect for job sites, camping, road trips, or even emergency backup power during outages. Turning a tool battery into a portable charging station is a game changer. If you’re like me and have a “mixed family” of tool brands, this adapter saves money and reduces the need to buy duplicate batteries. It’s practical, versatile, and incredibly convenient. Five stars for making my battery collection finally cooperate. Total power move

I was skeptical to buy this adapter at first. After a much needed self talk I took a chance and got one. Probably a very wise decision. This little guy works as good as hoped and probably alot better than I e pected. I personally recommend getting one. It's helped me out drastically.

I have a battery operated leaf blower which uses its own brand of 21V 2AH Li-Ion battery, which is not enough capacity (lasts only 10-15 minutes per battery) to finish the job. Of course, there is extra battery, but I would rather use a higher capacity battery that lasts longer time. One of the reviewers mentioned the Makita battery works in the same leaf blower even though the Makita battery is 18V. Since most of my power tools are DeWalt, I have several high capacity 20V DeWalt MAX batteries. This ZLWAWAOL battery converter is exactly what I needed for converting 20V DeWalt battery to 18V Makita battery. The DeWalt battery fits reasonably well (it’s not smooth, but manageable) into the adapter and the adapter fits (again, not smooth but manageable as well) my leaf blower. Most importantly, the leaf blower worked with this adapter. The quality seems fine and it look durable. Only problem is the insertion direction of both the DeWalt battery and the adapter are the same, which causes tight clearance (I mean really tight) between the leaf blower and the DeWalt battery. I wished the insertion direction of the DeWalt battery is the opposite. I am still happy with this purchase for my application. Now, I can use 6 -9AH DeWalt batteries to finish the job maybe with only one battery. I am not sure about the extra USB charging ports since I have no reason to use the ports for charging purpose, but I am sure it can be a useful feature.

This battery adapter allows the use of Milwaukee M18 batteries or Dewalt 20-volt batteries in Makita 18-volt devices - at least the one I have. It is annoying to be locked into one family of tools or having to buy different batteries and chargers for different tools. This is like jailbreaking. The converter worked without a hitch using either Dewalt or Milwaukee batteries. It slid on snug and off the batteries and onto the Makita device without difficulty. I recommend disconnecting the adapter from the battery when not in use, as some people have complained of their batteries becoming discharged or even ruined by leaving similar battery adapters attached to their batteries.

If you have the cheeper versions of the power tools that use the Makita style batteries, this makes fitting DeWalt batteries fit, and run longer. Instead of getting an expensive tool that you rarely use, I got a cheep one, and used this necause the original batteries dont last so much.

Worked great with a makita skil saw and impact wrench, also worked with a knockoff makita shop vac

Perfect for my NAVAC vacuum pump

Keep an eye on your battery power. This thing killed a cell the 1st use and the other battery I tried with it only no longer works with my DeWalt drill or charger. The battery fits but not great and my DeWalt battery is backwards when installed. Haven't tried the usb. Over all this thing wasn't worth 2 3.5ah batteries.
