It looks like this former uBeam engineer exposed Energous too.

The FCC does not allow you to transmit at the full 1 watt (30 dBm) if you focus the energy with more than 6 dB gain.  If you want to use a phase array to get 21 dB antenna gain, you must drop your transmit power to 25 dBm or 0.316 watts.  Every 3 dBi of antenna gain must be accompanied by 1 dBm decline in transmit power.
