This board has a good efficiency. Out of stock I measured maximum 92% at input voltage at which switch mode starts (3,5..4V depending on Vf) and minimum 76% (at 9V).
It's easy even to improve this good efficiency to 95..82% with two cheep SMD capacitors on ...
1) The output current is NOT regulated and depends strongly upon the input voltage.
2) Additionally the output current depends ...
