Charging Bench

Charging Benches are an addon to Industrial Craft that allow multiple tools to be charged simultaneously. This box will also unstack empty batteries automatically. Redstone current applied to the bench will reverse functionality, discharging batteries to produce power instead.

Recipes

Charging Bench Mk1

Charging Bench Mk2

Charging Bench Mk3

UI and use

Simply place what you would like to charge/discharge in the large area on the right. Connect IC2 cables to the sides or place a battery source in the box on the left to give/get energy.

This machine also accepts upgrades in the same slots used to charge items. Up to 16 Overclocker Upgrades can be applied, yielding up to 301x increase of throughput. Storage Upgrades each yield 10,000 extra EU storage (only limited by the grid slots in the device) and any Transformer Upgrades work the same way as in any other IC2 machine.

Differences between tiers

Name of bench	Maximum input/output voltage without upgrades
Charging Bench Mk1	32 EU packets
Charging Bench Mk2	128 EU packets
Charging Bench Mk3	512 EU packets

Note that while transformer upgrade components can increase the maximum safe input, the maximum output (when powered with redstone) will never change.
