Default 7210A-MPPT charge controller / step up only

First on the list wishing all a peaceful love filled day !

Next is this MPPT labeled controller that can be found for a suspiciously low price of $40 to $50.

Its marketed as a Solar lithium battery charger that will only step up the voltage as its designed to charge high capacity lithium battery packs.

It has a know bug when clouds first pass over it will stop charging for 10 - 15 seconds

Have a plan to test its input / output watt levels with a sine wave multi meter

Has anyone tested this against a actual mppt controller panel efficiency ?
