This question has some controversy on how to charge a Power Tool from the Modular Powersuits mod. While it is commonly known that both EU, MJ, and UE can be used to charge it, I want to know how something can be charged with MJ.
Unlike a Batbox/MFE/MFSU/AESU/IDSU which has a slot in its GUI to charge stuff with, Redstone Energy Cells and whatever engines do not have a slot to do this.
IndustrialCraft has the Charge Pads addon, which charges stuff with EU while a player stands on it. BuildCraft/Thermal Expansion/RailCraft… do not have anything of the sort.
So, how can you charge items with MJ?

From the wiki:
It would seem @Fredley is right (although I never doubted) and that it's much harder to turn MJ to Eu than it is to turn Eu into MJ. This makes it quite difficult to charge tools using MJ.
However, it would also seem Thermal Expansion offers an item that does just this. It is called the Energetic Infuser.
