Output power varies depending on the country code set and also radio hardware. Here with ETSI (PT) country code:
* 5180 MHz [36] (23.0 dBm)
* 5200 MHz [40] (23.0 dBm)
* 5220 MHz [44] (23.0 dBm)
* 5240 MHz [48] (23.0 dBm)
* 5260 MHz [52] (20.0 dBm) (radar detection)
* 5280 MHz [56] (20.0 dBm) (radar detection)
* 5300 MHz [60] (20.0 dBm) (radar detection)
* 5320 MHz [64] (20.0 dBm) (radar detection)
* 5500 MHz [100] (26.0 dBm) (radar detection)
* 5520 MHz [104] (26.0 dBm) (radar detection)
* 5540 MHz [108] (26.0 dBm) (radar detection)
* 5560 MHz [112] (26.0 dBm) (radar detection)
* 5580 MHz [116] (26.0 dBm) (radar detection)
* 5600 MHz [120] (26.0 dBm) (radar detection)
* 5620 MHz [124] (26.0 dBm) (radar detection)
* 5640 MHz [128] (26.0 dBm) (radar detection)
* 5660 MHz [132] (26.0 dBm) (radar detection)
* 5680 MHz [136] (26.0 dBm) (radar detection)
* 5700 MHz [140] (26.0 dBm) (radar detection)
* 5720 MHz [144] (13.0 dBm) (radar detection)
* 5745 MHz [149] (13.0 dBm)
* 5765 MHz [153] (13.0 dBm)
* 5785 MHz [157] (13.0 dBm)
* 5805 MHz [161] (13.0 dBm)
* 5825 MHz [165] (13.0 dBm)
* 5845 MHz [169] (13.0 dBm)
* 5865 MHz [173] (13.0 dBm)
So only channel 100...140 have full power (here for me, it may well be different for you if you are located in a different regulatory domain)
