Oh No ! I bought a Mppt Solar Controller
I don't believe it ! I bought it and I don't really even want it ! I was sure this would go for more than 12 bucks. Fooled me, oh well. Whats w/ links not working ?

Ok, now I get it. The dispute whether this is a fake MPPT vs a real one AFAIK from that video guy linked earlier in the thread, was that these cheapo so-called MPPTs did not have the whatever part on the circuit board when he opened it up.
IIRC, the real ones have a sort of doughnut with wire coiled around it and the fake ones didn't? And he said the fake ones used some other thing instead that didn't do anything "air--something" Not clear to me what he was saying.
Is that round thing with the wire the buck converter? Is there a different way to do that which could still be "real?" If I take it apart and don't see the round thing, is it game over and it is just an ordinary PWM?
Thanks.
