I received it works fine. Thanks.

Good and cheap 👍

Same parcel

It really increases everything. Both input and output. When 12V is supplied, we have 19V at the output. This is the minimum. More is possible, less is not adjustable. After 5 minutes of trying to adjust, the adjusting screws broke. More precisely, the thread in the potentiometers was covered. Not at all what I wanted.

The problem with the camera is no focus. The converter is good --- But. Initially, the output is supplied with 220/63V electrolytes at the output. I replaced them with two 680/160 ones, and the pulsations became much less. I RECOMMEND THIS PURCHASE. I took it for autonomous lighting.

Thanks

The product was received in a good package, without damage. I haven’t checked it yet, but I’m ordering it not for the first time, because it works perfectly within the specified limits.

The 15A current does not pull through the interference, it jams the radio; the 36V 60-watt light bulb is connected, and immediately one radiator begins to heat up quickly.

I didn't understand anything about adjusting the current. It works at XX and then short-circuits the input source. This is weird

Smooth adjustment! Everything corresponds to the description!

Thanks, got it, will test.....Works well
