    Arrived quickly. The quality of the soldering has become worse poorly washed with the flux. And other revision than in the photo. and the Green LED is almost no light when working.

    Ordered from the Russian government for more than from China, but very quickly! Delivered by cleat. The module works although the assembly in appearance leaves much to be desired!

    Hello Bratva. received this device assembly quality normal only potentiometers are not very good to move the current jumps you need to change them. Measures from 1.25 volts to 25.3 V. (power supply 25.4v) Slightly different from the picture, the picture shows the circle of this pribluda under the throttle of white paint. Came quickly, the store is sociable. Recommend

    9 days to Voronezh. Looks like in the photo, checked-it works. I use 4v 4.5A to power the LED, it does not heat up when 19V is powered.

    As in the photo. Checked it works. Let 18 V set 12 V outlet

    All the correct adjustment is does not push the unit to a large current to check but adjusts everything correctly and there is an indication if the current is limited, the flux remains in some places but not critical

    Thanks for the order made. Fast shipping and delivery. Adjustable and voltage and current, there are differences in the revision from the store’s photos. Installation is neat, the flux is washed.

    The work was not checked perfectly for the store. Thank you

    Arrived in a week. The input and output capacitors are confused. Thermal gaskets between radiators and power elements stand. The output voltage and current are slightly dependent on the input, but generally stabilize. Noise is not noticeable. Heating during long-term operation with current 5A is tolerable. 6A is already hot. This converter pulls the load 3-4 times more than the right.

    On the board there are flux residues and do not disappear until it turns on.
