Charger Automation
Note that since this uses a ME Pattern Provider, it is meant to integrate into your autocrafting setup. If you just want to automate a Charger standalone, use hoppers and chests and stuff.
Automation of a Charger is fairly simple. A ME Pattern Provider pushes the ingredient into the charger, then a pipe subnet or other item pipe pushes the result back into the provider.

Configurations
- 
The ME Pattern Provider (1) is in its default configuration, with the relevant Processing Patterns. It also provides the Charger with energy because it acts like a cable.

 - 
The ME Import Bus (2) is in its default configuration.
 - 
The ME Storage Bus (3) is in its default configuration.
 
How It Works
- The ME Pattern Provider pushes the ingredients into the Charger.
 - The charger does its charging thing.
 - The ME Import Bus on the green subnet pulls the result out of the charger and attempts to store it in network storage.
 - The only storage on the green subnet is the ME Storage Bus, which stores the resulting items in the pattern provider, returning them to the main network.
