How much electricity does an Airport Express 802.11n use (approximately)?

Is turning it off at night to save money a good idea or a bad idea?

AirPort Express 802.11n (1st Gen), Mac OS X (10.6.8)

That's exactly the data I needed to know. Thank you very much!

I was concerned because the Express is always quite warm, which sometimes can mean big energy bills.......🙂

I've just measured it using a digital wattmeter, and it draws 4 watts when idle. This means about 3 kWh/month, or 0.60 €/month (at my current 0.20 € / kWh), so it is not the culprit of my huge energy bill...


Surely it is not worth the hassle of unplugging it everyday, with the accelerated ageing it causes to the device.
