Those percentage losses between each step isn't a big deal for a 50w power requirement for a fan or something, but when you have a big motor which needs a hit of 75A 18v (~1350w) for max power, that's no joke for an AC to DC power supply (See how big 1000w+ PC power supplies are?) There are efficiency losses in each one of those conversion steps. * 1-phase 120v AC - > 18v DC -> lights/circuitry
* 1-phase 120v AC -> 18v DC -> (not sure voltage) 3-phase AC -> motor If there was an AC converter to plug it in, that would require the following conversion paths to get the power the tool needs: They also use the DC for all the lights and smaller things in the device. The current set of FUEL tools have brushless motors, which accept DC and then gets converted to 3-phase for the motor. Yes, some of the tools are made with universal motors, which could be ran off of DC or AC, but that would still require an AC transformer to step it down to 18v. They do allow some devices to be plugged in, but that requires an external power source with its own electronics and that's only for stationary tools such as fans or lower amp requirement devices. Not trying to defend Milwaukee (I do bleed team red, ha), but I believe there is a technical and design reason why they haven't done this.

Do you have another issue not talked about here going on with you adapter? If so please let me know in the comments section. One great thing about Dewalt is that most of there products come with a 3 year warranty. If you have tried all of these fixes and the adapter system is still not working, you should reach out to Dewalt at: 1-80. Hard to connect/disconnect battery from adapter.Dewalt’s switch from 18v to 20v battery system.Sometimes the fix is much easier then you would expect. If that is the case for you, be sure to run through the checklist before reaching out to Dewalt. There are many different reasons why your Dewalt 18 volt to 20 volt adapter may not be working. That means you have to have a 20v charger. Or is the tool the issue?Īnother common complaint that I hear is that you cannot use an 18v charger. Remember this is a 3 part system: the adapter, the battery and the power tool. If you are positive you have done everything correct when using the adapter but it still does not work, it is time to look elsewhere. You may be able to adjust the angle of the tool to fit but sometimes this can significantly limit your project. The height of the adapter cannot be changed. Unfortunately there is not much you can do about this issue. Therefore they will not fit on the adapter. Anything above 5 ah has an extra seam on the battery. I have found the adapter only works for 5 ah and below.
The premium and FLEXVOLT batteries are higher ah (ampere hour). It will not work on the newer 20v or 60v FLEXVOLT series.ĭewalt also states on there website when purchasing the adapter: “Do not use with Premium Batteries (DCB200, DCB204, DCB204BT, DCB205) in 18V Compact drills DC970, DC759 (use DCB201, DCB203, DCB203BT)” When purchasing this adapter from Dewalt they make it clear that it only works on the 20v max batteries. Unfortunately this adapter does not fit for all of the new batteries that Dewalt has released. Battery does not fitĪnother fairly common complaint is that the battery does not fit. As you press the button you should be able to slide the battery right off the adapter. To disconnect the battery from the adapter you must press this same button. If this is not done properly the connection will not be strong enough for the tool to work. If it is done right, you should hear an audible click, this will indicate that the battery is on the adapter properly. You MUST press this button when sliding the battery down the adapter. This is the same button you press to remove the battery from a tool. As seen in the picture, there is a yellow and black button on the battery (color will vary depending on battery).
