I would like to get WiFi from our home to an RV a 10th of a mile away using two CPE510's with a clear line of sight between them.  The problem is the RV has only 12 volts power.  I'm thinking I will get the TP Link TL-WR902AC mobile router which is USB-powered, but I will need a 12v-to-24v POE adapter for the CPE510.  Any recomendations?
