Energy usage of Pengagram Cerberus P6369?

Some time ago I described power consumption of Linksys WRT54GL. Pengagram Cerberus P6369 is cheap router with 4 Ethernet LAN ports and 150 Mbps Wi-Fi (802.11n). This one wasn't mine, so just a quick measurement when on idle router was performed (WAN cable plugged in). The result was 2.2W, so it uses over 3 times less energy than old Linksys, providing faster connection.
