Energy saving? Nah...about the same as using 3 different cradle docks, also not every one uses an all Wahl set up. I'd give it a point for organisation though.
This is way nicer though, I've got a KrazyGood box and the inserts, especially for Wahl clippers, are not nearly as nice as these. The KrazyGood is essentially just a cord end you're plugging in, this looks like it has the contacts, so the clipper sits in instead of being plugged in. Plus KrazyGood is 3d printed, these are molded
