Make teleporter have more two teleporting modes. [by opening a gui on teleporter and choosing mode]
Energy teleport mode:
It would send ALL energy on adjacent MFSU/MFE to
other teleporter (the power would go to its adjacent mfsu/mfe) at the cost of 10-25% [Distance cost]
Item teleport mode:
it would send any items that are thrown on portal particles at the cost of item teleportation (IC² wiki).
Edit: inside any adjacent chest to destination teleporter.
