Review on DROK Converter Mobile Battery Indicator by Todd Amarsingh

At first I had problems with this converter. When I first tried to connect my phone to it, my circuit kept turning off. At some point I realized that my phone was drawing too much current for the converter. On my phone, I was able to fix this by going into battery settings and disabling fast charging, which caused the phone to only draw 1 amp from the charger, albeit at a slower rate. Other than that, the rest of this charging circuit is built pretty well. . I tested its output at 5.17V which is perfectly safe for phone charging. It gets a little warm during operation, but that doesn't bother me. All in all it's pretty good.
