Review on 🔌 DROK USB 3.0 Hub Multi Tester with OLED Screen: Pocket Digital Multimeter, DC Voltmeter Ammeter, Capacitance Meter, Thermometer, Energy & Time Battery Monitor, OTG Connector Output with Auto Off by Tio Kotaki

This is my second purchase of this product, the first was given to a colleague as a gift. This multi tester is great, I checked all my USB network connections to check the output and even tracked the battery levels of devices (phone and tablet). I haven't installed or used the alerts feature, but this can be useful when doing long-term trend analysis. I never knew how much I needed something like this until I bought it. You know, I can't imagine not having it.
