Charging Benches are devices that allow you to charge up to 12 electrical tools and items at one time. There are 3 tiers; each designated with a specific mark version. They can generally charge items faster than placing them into the charge spot on a MFE or MSFU. Also if you place a stack of items in it will separate them into invidual spots until all are full. If there are still some items stacked, they will unstack as individual items are removed from the bench.
To charge an item place it to the right grid, power sources can go in the left box, or be powered by cables. Some items will not charge in the lower mark charging benches (i.e.: Mining Lasers, LapPacks) The reason for this appears to be too low of a current, which may mean it does charge the item, just incredibly slow. The exact specifics on what EU charging benches have coming from them is not known quite yet.
If the bench is redstone powered it will discharge the items inside to emit power.
