Power consumption of wireless router

Found 22nd Feb 2010
We have noticed that since we got a land line and broadband our power bills went up by ~£35.

ukpower.co.uk/too…ty/

Using this calculator I worked out that it costs us £19 a month to power our wireless router costs.

It reads 230V ~50Hz 0.5A, works 720hours a month (always on), the electricity costs us 23p pkw ( ~6p at nights but I dont include that in this calculations)

Same with phone wichs runs at 0.45A

Both plugged in all the time would work about £30 a mot (thats including lower night rate)

Are my calculations right?
Do you experince the same 'problem' ?
Why don't you turn it off over night at least, as that will save you what 7+ hours a day of electricity from it
really cant see how a router can cost £30 a month just to run. our leccy bill an month is around £40 and ive got mine on all the time aswell as having the dishwasher, washer, dryer all at least twice a week....

some leccy guru may be able to clarify tho....
I just relalised that the router and the phone are consuming that much power.

If I were to turn the router off during the night, that would save me 5-6 pounds a month. :thumbsup:
Same with phone :thumbsup:

But It is still a lot :oops:
We used to spend about £40 a month.
Now it costed us £68 for December and £72 for January :oops:

My calculation shown that including the night rate the router cost £17.5 to run. (30 is the router and phone together)

Our dishwasher runs daily on low programe (30*), Washing mashine 3 times a week and we have 2 big TV's and other stuff. And it used to cost us £40 a month to run it all. Now it is around £70.

Can you check the values on your routers power supply?
God i hope this is wrong!! my ruter will be going in the bin and back to that long cable again
Does it not have a transformer that steps the voltage down to something like 9-12 volts?
I lol hard at someone thinking their router / phone costs £35 a month to run

more like 35p!
btw, my router is 15w so about 30p per month assuming 24/7 hr usage

it aint a microwave lol
router will probably cost about 1-2p a day to run. think you need to recalculate.

This is about right. A router is a low power consumption unit. I have an electricity monitor and it hardly shows that the router is there. So I think the calculations are wrong at £35.00

[FONT=arial]Assuming you do not turn your router off, this would equate … [FONT=arial]Assuming you do not turn your router off, this would equate to 0.24kWh / day and 87.6kWh annually, costing approximately £10 per year to run .

I own D-Link DSL 2640R/TT router (free with 8mb talk talk broadband plan)

The router itself runs at 12V 1.2 A
The step down transformer reads 230V 50Hz 0.5A thus 115W (W=V/A) can also be worked out with this calculator crownaudio.com/app…htm )

24h X month (30) = 720h (total including night rate)
night rate 7h X month (30)= 210h (night rate only)

720- 210= 510 (total for standard rate only)

510h at standard rate
210h at night rate

price per kWH at standard rate = £0.23
price per kWH at night rate = £0.06

510 X 0.115kW = 58.65kWh
58.65 X 0.23= £13.49

210 X115kW = 24.15kWh
24.15 X 0.06 = £1.45

TOTAL for 30 days for router only= £14.94

This can aslo be worked out with this calculator ukpower.co.uk/too…ty/
your router is 14.4watts, I would be worried about my health if a router was using 115 watts

I stopped using wireless land line phones, stick to wired as it's free to use then.
"The step down transformer reads 230V 50Hz 0.5A"

This is the maximum not the rate at which the transformer runs,

I have no idea if i'm correct, but you have it as 115W by dividing 230(V) by 0.5(Amps) surely it's 12(V) by 1.2(Amps) = 10W?

115w....you would be cooking food on it!

remember your plug is a transformer so you are not using 240v electricity but 12v, so recalculate and see what you get!
My Netgear plug says 240v/50hz/100miliamp so that's 24 watts/day, 8760/year or 730/month.

Electricity is about 10p/kw so it works out at 2 to 3 pence a day.
Someone needs to go back to school if they honestly believe that a router costs more than a few pence a month to run.

Hi @Christian_knox
Thanks for posting but this thread is 8 years old now so I would hope the OP has this sorted by now
