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)

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.

Works as described - I use my Dewalt batteries on EVERYTHING.

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 works very very well. I have Makita tools and the Dewalt batteries work great in them. I saw some bad reviews but I have not had the same experience- battery life is the same as using a Makita battery.

This fit and adapts my dewalt batteries to other brand tools I have, saving me bucks on new batteries.As others have stated, do not leave your batteries plugged into the tool with this or it will drain them. Not sure why this happens and it is a little concerning that there’s something causing this, but I don’t leave them in and therefore I’m with the batteries and tools at all times when they’re together, so it’s a none issue for me.

It works good

Used a brand new 6ah dewalt battery on my makita trimmer and it would start to rotate for a split second then cut off. Started to smell like burnt wires so I pulled the battery before I damaged it and sent this junk back. I'd heard OK things about the adapters but I just decided it wasn't worth risking my batteries.

They fit great and are of higher quality than some other ones of purchased I use them with my Milwaukee batteries on a makita vacuum everyday and haven’t had one issue with them. Also being able to use my dewalt batteries with them and being able to charge my phone with them is awesome! For the money you can’t go wrong great to have around the house or garage or work van if you have several different tool brands like me!
