Review on Charger Vympel 57 black by Michal Cedronski ᠌

Revainrating 4 out of 5

A good product at a good price, I advise you to try it.

Chinese pulsers for powering 12-14 V LEDs and for a current of 30A inside on VID are much more reliable, not only they look: both the 390 uF capacitor at 400 V and the filters over the network are full-fledged, they give less interference and are much cheaper, but it's not about the price . I thought that in RUSSIA our designers would still be made more reliable, with a margin, so to speak . WRONG!

Pros
  • The functionality for the charger is normal - everything works, but as a power supply it “sucks”: it’s difficult to use when setting up radio equipment for a car: there are no separate terminals, impulse noise, mom don’t cry . unless you turn on the autocompressor in the garage, vacuum cleaner or check the light bulb. Conclusion: you can use it, but CAREFULLY, CONSIDERING THE FOLLOWING FAULTS!
Cons
  • It looks flimsy - immediately sacrificed the guarantee and dismantled it. the manufacturer did not lay out the diagram, but after reading the reviews he decided to check the reliability himself: there is no surge protector, which is mandatory for an impulse switch, there is no mains switch (when using dancing with tambourines), thin wires for 20 A, "flimsy" crocodiles, the power cord is not very short, it’s also unreliable, and it’s not even fixed inside, only on soldering, you pulled it a little harder to tear it out, however, the output wires are not fixed, only on soldering, they will fall off over time, it’s like giving a drink. It could have been more impressive, for example, take a standard one from a computer with its own socket on the case and a switch, output for screws and solder. The capacitor in the primary rectifier is 100 uF x350 V to no avail: the capacitance is small (it will dry out over time), it will only withstand voltage up to 240 V in the network, but it can be much more in the network (for example, 260 V, and this is max- 366B) . explodes, as it happens with many. And what? Before switching on, measure the mains voltage ? Eliminating all this is not difficult, but apparently no one needs it. You'll have to "finish" yourself.
