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. The b-box 3 of Proximus is in this last category.


So I measured the power consumption of a b-box 3 starting up. Below is the result. I’ve stopped measuring once the device was fully operational.
bbox3 power consumption
Note that the steady state power consumption is 8.5W, which costs around €15/year at current prices.

    It sure takes forever, doesn’t it? It might be interesting to check how much of a difference disabling wifi makes, although you have to leave it on if you want to enjoy Fon access elsewhere.

    From my experience with other routers, WiFi itself doesn’t consume that much (around 0.5W). It’s mostly the CPU and modem chips that consume power.

    True, it might consume a few Watt while transmitting but mostly it’ll be idle anyway.

    Hi,

    What hardware do you use to measure and log those consumption values?
