It would be beneficial to include for home miners which models have low power settings.  A 2.5-3 kw miner can be used in home/hobby setting with a low power mode.  Power input voltage is also handy as quick reference on a list since some mfg's require 220v and other list 185~285V. 

With that being said, I would request a separate thread on voltage regulation.  I recall Phil had mentioned, think it was s15 thread Norstar Power Converter with Voltage Stabilizer and a Larson Buck/Boost Step-Down Transformer as options but have seen a follow up as far as functionality or durablity.
