5A DC-DC Step Up Power Module Boost Volt Converter 3.3V-35V To 5V 6V 9V 12V 24V XL6019 Adjustable Output Regulator

Consider using a 12v dc fan with it for the maximum best performance possible otherwise it will overheat and dropp voltage. Working fine for me and the board quality and voltages are stable . Very small and compact size . Worth buying it.

The m7 diode burn when I give input i gave 3v and even try 10v both burning the diode and yes I correctly fit the positive and negative

Good product

working perfectly used it with 7.4 3500 ma Liion cells for a 12v Electromagnetic lock load varies from 700ma to 2000ma and this unit works perfect between 4.5v to 8.4V without turning hot. if given less input voltage than 4Vand taking out more than 12v output; if unit running at more than 2 to 3amps it starts becoming hot. so keeping in mind its limit this circuit will work in satisfactory manner in most projects.

Ok

Best one when compared with other options,The components and board are of very high quality. Does it's work as described.

Product is NOT working properly at lower than 5v input supply.However it works just fine at 5v+ input voltage.

Purchased 2 pieces. One is working fine. The other was damaged (a potentiometer lead was broken).
