Review on 📱 Mini Portable Micro USB OTG Adapter with 4-in-1 SD Card Reader - USB 2.0 Port & SDHC/TF Card Slot for Android or Windows Phones (Micro USB Card Reader) by Marcus Amillion

I bought this to use with my Samsung Verizon Tab S. I've used it a few times without incident and all the parts attached have worked flawlessly. I recently had the opportunity to leave the stick plugged in, but I also had to plug the power cord into the micro-USB port to allow the battery to charge. It did not work. After that I just plugged the power cord into the adapter and it still wouldn't charge. Removing the adapter and plugging it in directly started charging, confirming that the problem was with the adapter. Having had the adapter for several months before discovering this problem, I can't ask to return it for a replacement, so I'll just buy another one, hoping everything works properly. I will write my review after I receive and test it. I just got a second one and I have the same problem, it doesn't allow charging when the power cord is connected through this adapter. Downgrading to three stars only because I can't tell if other mini USB devices are recognized or not.
