Reply to "ZW vs Modern Transformer Power Useage"

Ive been thinking you might be able to check with an inductive amp meter ("amp clamp", meter with the carabineer like hook)

Like a wallwartIwallwart,t the windings would have a vampire draw on both too. So wattage (which is input watts) would be the difference in use.  (unplug when off and using a battery to save the battery for more use).  I think the efficiency of the new one is in distribution, not draw, if both have pure sine windings. (the MRC pure sine as well, but not the other MRCs. Those may draw less at a low voltage/balf throttle.  

Kinda wiped out, gotta sleep on it.
