The Charging Bench allows you to charge multiple items at a time. Simply right-click to access the GUI and place items to be charged in the Charging Bench's inventory. It will automatically unstack empty RE Batteries as they are charged.

The Charging Bench's capabilities can be enhanced using upgrades. It can also be powered with Redstone, instead of EU
