No, but we have tested an inexpensive adapter that we can recommend. POE Texas’ Adapter can be purchased directly at or from Amazon.
Note: It’s important to order the Micro USB version. This adapter has also changed connectors since our initial purchase. You may want to consider the UCTronics adapter below. One of two of these POE Texas adapters we tested failed after 9 months. The other is still running since May of 2000. Full disclosure: The adapter failed while powering an alternative StingBox platform we were testing. The platform still works, but the POE doesn’t. This isn’t a sufficient data set to say for certain that the power supply was the cause of its failure.
There are several other manufacturers on Amazon 7/2022
Update. StingBox customers are giving positive reviews of this POE splitter from UCTronics
