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 Duane Mann

I am very satisfied with my purchase of the Drok USB3 multifunction tester. I also bought the DROK Micro Load Battery Tester Board USB 0.15-3A 15W Adjustable DC Electronic Load, Aging Tester with Smart Detector, which I highly recommend if you want to do any type of analysis on your chargers and batteries. That's why these excellent tools cost me so much money. I started testing all my USB chargers and power adapters and found that about 70% of them were useless and couldn't maintain an adequate charge level. My findings necessitated the replacement of all "bad" (weak) power supplies and power supplies. It wasn't cheap, but now I charge my phone and iPad in record time, and my power adapters charge faster and can maintain good output power.
