This buck converter seems robust and good but it has a high power consumption without load that depends on source voltage: 0,10 W at 9 Vdc to 0,4 W at 24 Vdc. I don't know if it's a fault or it's the normal functionality

Excellent DC/DC converter, output up to 25watt 5v USB charging. very efficient with 30 watt solar cell. Charging laptops possible.
