Customer Review

Volts and amps are displayed alternately with the KW-202. I ordered, two, to check the charging current of my solar panels can. When voltage indicator which still works reasonably, but the amps display like a random generator, the numbers bounce wildly. A clear result is not legible.

I have two instruments from other manufacturers under the same conditions show both correct. Apparently, the KW-202 with the variations of the solar panels is not clear, because when you connect to a PC, the display remains readable.

Another drawback is that max. 0.5A to pass through. So if for example, its battery, mobile phone, which also wants to always watch when charging, a charging brake is built in with the KW-202. (Unfortunately also applies the KW-203).

Conclusion: Whether one is happy with the KW-202 depends greatly on where and what you use it. In combination with solar panels I advise against it. In general, the display shows fewer (volts and amps) as compared competitors' products.
