correspond a mes attentes;
It's a 10 pcs packages, 8 are OK and one under voltage, one short circuit. The first part of the video shows the good one output about +5V. The second part shows the under voltage one output about +4.3V, is too low for video TX and others. The third part shows the short circuit one, and component separated after first power on. https://youtu.be/kfE5GDzHCPc https://www.youtube.com/watch?v=kfE5GDzHCPc&feature=youtu.be
9 of the 10 units all functioned within acceptable voltage limits 1 seemed to just give input voltage straight through minus a diode drop. None of these units can supply the 3 amp current suggested in the description.
