Review on DAOKI Step Down 4 75V 12V Regulator AMS1117 3 3 by Chad Baio

Revainrating 5 out of 5

Good enough for my needs

Everything tested. Five of these are in the 3.35 range and the other five are in the 3.2 range. Ideal for replacing 3V lithium batteries by soldering wires from the battery terminals to the tanks and from the tanks to a powered USB hub. Now I can draw about 1 amp from each "battery" and never have to worry about batteries ever again.

Pros
  • Note: AMS1117 3.3V Step Down Voltage Module Solder Kit only supports 3.3V 800mA output, so the load current cannot exceed 800mA.
Cons
  • Long delivery time
