Review on Sabrent Portable Worlds Smallest HB MNBW by Joseph Rasmussen

Just received and tested. I love how tiny this thing is, but I don't like that it doesn't work on any of my current devices. So far I've tried charging: LG Stylo 4, Samsung Galaxy S5, ZTE MaxPro, as well as a "wireless" USB travel light. ALL 3 phones were already 70-80% charged but refused this charger and slowed down the charging time instead of speeding up the charging time. After 15 minutes, phones were up just one percent despite being the only device connected at the time! The lightbulb didn't recognize it at all. I'll be leaving it for a few more days hoping it actually works for other USB devices I have around the house, but so far it's been a failure. I will either update this post positively or undo. :-(
