The output from this counterfeit charger is really a wall of noise. In an effort to healthy the waveform while in the Exhibit, I needed to double the size over the still left and enhance it by an element of five on the best, Hence the yellow curve is actually A lot even worse than it seems.

The graphs in this area have to have a certain amount of explanation, that's presented while in the diagram under. The voltage/present load curve demonstrates the functionality with the charger beneath unique masses.
