Review on Charger Vympel 57 black by Janis Ziemelis ᠌

In terms of the quality of plastic, assembly and wires, the device does not resemble a laboratory device . But the price and functionality are excellent! Satisfied. Pros below: Lightweight yet powerful. In addition to smart charging, it can be used as a voltmeter and as a powerful power source for devices with constant power supply in a wide range of voltages and currents (7.4 - 18 V, 0.8 - 20 A). When charged as a percentage, it shows the charge level of the battery. Very comfortably. As a "start-up" device, you can quickly revive a run-down battery with a high current of up to 20A. Has cons: Wires and terminals - so-so, but sufficient for safe charging. They get warm at high currents. I remind myself of a safecracker who opens the safe when I try to set the necessary parameters with an accuracy of tenths with very sensitive knobs of potentiometers.
