![]() There is a business decision too: If people need more run time, they'll buy more batteries, which is more money for them. They would still need a DC converter as well for all of the other little stuff! Milwaukee has shown and said they are sticking with M18, and a design change would go against that pledge. Well then how about have it so the electronics that convert directly from single-phase AC to 3-phase AC be in the device itself, bypassing the need for the big DC converter? That is a good idea.but that drives up the production price of every unit, and would need a whole different connector design with more pins. 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.
