Review: MPPT-M20 Solar Charge Controller #1 - It's a Fake

I was half expecting this controller to be real MPPT - or at least have an inductor and do a modest amount of DC/DC conversion. But no, it's an out-and-out fake, a fraud, a con, a rip-off. It looks like a PWM controller though, so it's worth checking how well it works.
