  80. R***v

    Received within 3 weeks. One has already been tested. The accuracy of voltage readings is about 50 mV at levels up to 10 V., and about 120 MV at levels above 10 v. Pleasantly surprised USB output: Keeps the load up to 2.5 A (ran for 15 minutes), while the voltage fell only to 4.89 V. (no load about 5.15 v.). The LED voltage line displays from ~ 10.5 to ~ 13.5 V. In step about 0.45 V. For me there is one Minus: The fact is that with the help of the LED line I was going to track the voltage sagging on the battery when starting the engine. So this thing is very inertial, because of which it does not even have time to respond to a short-term voltage reduction… Otherwise, I’m happy…

    Took in return мен (worked a month), which took in the local store and the hole that cut in the panel had to be something worker to shut down, when found on the ališka yes another 3 times cheaper pleased, ordered it. The goods reached 25 days before kostanya. The result got, set everything earned, but the next day stuck and ceased to charge (before it skipped when charging did not heat at all). The conclusion of the idea is excellent, but the quality of the product (reliability)-absolutely no money for the wind

    Today, the volt meter readings are more or less accurate. the escape of about 0.2 V. is not critical. The main thing is that the voltmeter readings are not replaced with current and temperature readings, as this often happens in annical devices for a cigarette lighter. Therefore, even a short-term change in the voltage of the onboard network can be traced.
