Review on πŸ”Œ 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 Warrick Infinite

It's a great value for a handy, portable USB 3.0

. It's a great price for a handheld USB 3.0 portable tester, but a bit pricey ($29) for use as a constant charge controller, in my opinion. Li-Ion batteries last longer if you don't fully charge them, so I use the UC (Low Current) auto shutoff to stop charging my tablet when the charge current drops below 1.2A - at which point it is my tablet charged to 80%. Without this device, it would charge at 100% and draw around 0.4A indefinitely. My only functional complaint about the DROK is that once it's turned off, the device won't turn back on unless I press a button on the device or momentarily remove power from the charger to allow it to restart. Therefore, it will not automatically maintain a charge. Not a big deal, because at this price I still don't want to leave it permanently installed as a charge controller, as I have my doubts about its durability under continuous use conditions.

Pros
  • . Excellent overall performance.
Cons
  • . Doubtful.
