How much electricity does the Wi-Fi router consume - even 100-200 euros

What is the tutorial about How much electricity does the Wi-Fi router consume?

In this video tutorial (How much electricity does the Wi-Fi router consume) we will see how much it consumes in the Wi-Fi router and at what costs to expect, especially since the router is connected to the outlet non-stop.

Not all routers are the same - some consume a lot, others less

Low-power routers:

These are simple routers and generally quite simple.

They only have 2.4 Ghz wireless bandwidth, 100 Mbps wired connections (Lan and Wan), less coverage. These routers do not do well with crowded places with many connections.

Highly consuming routers:

These routers have many features, 2.4 and 5 Ghz bands, support multiple connections, 1 Gbps or even 10 Gbps wired connections.

In addition, on routers that consume a lot, we find VPN servers, FTP, USB ports, we also find antivirus, network streaming media functions, complex parental control, etc.

In addition to a simple router, some users have other devices connected to the network

My configuration, for example:

Huawei ONT Router (from Digi)

Asus AC56U Router

Router Mikrotik HAP ac

Zixel POE switch

Hikvision surveillance camera

Consumption of the above configuration is around 50 Wh

How much power does the Wi-Fi router 1 consume?

How much does a non-stop plug-in router cost?

In the tutorial I did the most optimistic scenario, with a router that does not consume too much, but is not too powerful.

That consumes around 3 Wh which means 3 Wh x 24 hours x 365 days = 26 Kwh per year, and in lei it means 52 lei at today's Enel price

In the case of my complex configuration above, with a lot of network stuff plugged in, the consumption reaches 50 Wh, ie 50 Wh x 24 hours x 365 days = 438 Kwh per year, and in lei that means 876 lei per year

How do we choose the router to consume less

How much power does the Wi-Fi router 2 consume?
How much power does the Wi-Fi router 3 consume?
How much power does the Wi-Fi router 4 consume?

On each router power supply you can see the maximum current and voltage of the power supply, where it says "Output"

There we see the voltage and current, expressed in Volts and Amperes.

For example, in the first image at Output we have 12.0V and 2.0A. Multiply 12 V by 2 A and we have 24 W maximum possible consumption.

This does not mean that the router will consume so much, but theoretically it could draw a maximum of 24 W from the power supply.

Even if the value we calculated above does not indicate consumption, it will at least help you get an idea of ​​how much you can consume.

However, from experience (empirical observations) I realized that the router generally consumes about half of the maximum power that the power supply can output.

Huawei from Digi consumes around 12W with Wi-Fi on and under 10W with Wi-Fi off.

Balanced router recommendation - consumes little and has enough features

    In order to reduce consumption, I switched to programmable and, more recently, smart outlets. At night, various consumers are automatically switched off, as well as when no one is home.

  2. Very good idea. Even better than using the Wi-Fi signal at night.

    I sit and ask myself: apart from the devices he presents for example, does Cristian have to buy other devices in order to be able to answer all the questions? It wouldn't be easier for someone interested to buy a wattmeter. At least that's what I did.

  4. Golden rule no. 1:
    To make real savings on electricity, unplug all light bulbs and appliances.
    Golden rule no. 2:
    You buy a system with a photovoltaic panel, if not for the operation of large appliances, at least to charge small appliances (phone, tablet, laptop, USB power battery with USB charger, USB shaver, flashlight, USB rechargeable batteries, etc.). With the photovoltaic panel you will save 30% of the house's monthly electricity by charging these small appliances (between March and November and the maximum solar energy is from July 15 to August 15).
    Golden rule no. 3:
    Unplug one or two devices as long as you use them, then unplug them. The exception is the refrigerator, which must be plugged in 24/24.
    Golden rule no. 4:
    Buy only usable battery-powered electrical appliances. These USB charging devices represent the future because they will charge from photovoltaic panels, so zero consumption.
    The rest are stories!
    The programmable socket is a device that also consumes energy.

  5. Cristi, if you would like to do a tutorial on how to set up Automatic Wi-Fi Shutdown on your DIGI router. I set the stop and start time and nothing happens. That is, the wireless signal does not stop. There would be another problem, if you watch TV at a certain time just when the wireless signal is interrupted, it means that the TV does not work anymore because it has no signal.
