When I buy electronic devices, I always keep an eye on their power consumption. Especially the power drain that you’ll get 24/7. For most devices, this is their “standby” power consumption, but some devices are left on all day long. My broadband router, a TP-Link Archer C7 running OpenWRT 15.05 Chaos Calmer, is in this last category.


So I measured the power consumption of the Archer C7 starting up. Below is the result. I’ve stopped measuring once the device was fully operational.

Note that the steady state power consumption is 3.5W, which costs around €6.1/year at current prices.
