Issue Description:

Want to insert energy to EnderIO's item cap bank ,tools ,armor and other hold energy item.
But can't find the energy capability for items.
I find this https://github.com/SleepyTrousers/EnderIO/blob/1.10/src/main/java/crazypants/enderio/power/ItemPowerCapabilityBackend.java

where the capability exactly is.

Affected Versions (Do not use "latest"):

• EnderIO: 3.1.193
• EnderCore: 0.4.1.66
• Minecraft: 1.10.2
• Forge: 2422

Thank you! Solved this.
