Very good and stable product. This is the second i bought, because it is really oke
Very nice product and very stable output. I tested with an input ranging from 4.9 to 25 volts. Tested with a load: of 2 Amps, unfortunatley i did not have other suitable resistors to test with higher load. Input, Output 4.94, 11.90 5.01, 11.86 6.99, 11.83 10.00, 11.81 15.00, 11.80 19.9, 11.79 25.0, 11,78 Very easy to set to another output voltage. I wll set the output voltage to 14.4 volts, to charge my boat battery by solar panel. Very happy with the product.
