Review on Charger Vympel 57 black by Mateusz Wysokiski ᠌

I would like the manufacturer to make the case of the device, well . more aesthetic or something. The same wires can be softer and thicker, in the cold "oak" . Has some pros: The device as a whole is not bad. There are knobs for adjusting current and voltage, while displaying their respective values ​​on a backlit digital display. Ability to work both in automatic and manual mode. Also, the advantages include the possibility of using the device as a power supply. Its cons: Initially, the adjustment knobs were deeply recessed so that the front panel on their side was deformed and they spun with considerable effort . It was not possible to pull them back without risking damage to the board on which they were soldered. I had to ignore all the guarantees and open the device. When turning the adjustment knobs on the opened device, it is visually noticeable how the board on which they are soldered “plays”, which could subsequently result in a breakdown of the contacts of the additional board on which the variable resistors are installed. After simple manipulations, I installed the control knobs in their place. After that, the ease of adjustment and deformation of the front panel was restored. The swing of the board in the contacts also disappeared.
