There was a low price Toocki charger I ordered and it already shipped when I found Russian youtubers showing it's shit. High ripple voltage. >200mV ripple at 5V. Multiple guys have shown such results.
I have measured 250mV ripple on the cheapest USB supplies with no output filter. Just a little SMPS chip and then straight out the USB port. That's is bad. The Toocki charger has to be as cheaply made.
This knocks Toocki down to low tier brand in my book.
