Yes, I know that was mentioned many times, but no one gave any specific information except some enigmatic ‘protections’ etc. If I have 7.5V, 1.2A power supply, with good current rectifier and current limiter, what else that original have inside?

If you are an electrical engineer with the ability to build or otherwise have a very expensive power supply that is regulated, has protections, and never ever varies ONE BIT.  Then yes maybe.  But again it is NOT worth the risk.  We have seen MANY people over the years think they have a solution only to blow a newton a few days to months down the road.  So I repeat: it is NOT worth the risk.

Is not about risk. I’m asking, because I have a plan to build special power adapter to power 5 Newton by one power adapter.

Yeah, I will ask Frank. Thanks.
