Power output at 3V is roughly equal to power input at 12V, so the input current is much lower than the output current. Minimal dissipation compared to a linear converter. **Q: So, if i have a device that takes 3v .225a, even though this outputs a max of 3a it should work fine?** A: Yes, absolutely. This module is voltage-regulated, meaning it regulates the output to 3V, and will provide whatever current the load draws, up to 3A maximum. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Needed to power a candle timer without batteries. *by R***9 on Reviewed in the United States on 8 June 2024* I used this device to convert a solar panel 12 vdc to 3 vdc and remove the batteries.
