Router 12v

[billynomates37]

Hello.

Im having my broadband installed tomorrow.  The router cable will not be long enough to reach the power source.

Have seen extensions on Amazon. Anyone out there know what the male/female size is need.

It's the black router.

@billynomates37 What are you having installed tomorrow that requires the change to the power source length for the low voltage cable.

You would be quicker to run a single socket mains extension than try to find a barrel adapter cable of BOTH correct sizes to fit, but looks like it is a 4mm x 1.7mm but do not hold me to that fact....

Hi

The router sits on a corner shelf above a power socket.  I'm short by a few inches(story of my life).

Its either an extension lead or move the shelf down which will be added faff.

The supplied ethernet cable is also too short but I have a longer one I can use.

@billynomates37 As i say do not hold me to the sizes but have a look, try and measure the plug for yourself....

4.0mm x 1.7mm Female to 4.0mmx1.7mm Male DC Power Plug Extension Cable DC Power Adapter Cord 5ft 1.5...

I've tried to measure but 2.1 and 2.5 look very close.

Will order one of each i can always return them.

Thanks for your help

@billynomates37 Never even thought to ask, but i was looking at the adapter on the SR203 hub, just so you know. My bad....

Once you know the correct do post it up will take away any future guessing.

Will do

Old techy's tip.  You can use metric drill bits as a gauge.  If a 3.0 doesn't fit try a 2.5, if that doesn't fit it will be a 2.1.  Simples!

Excellent tip.👍

 So, was it 2.1 mm or 2.5 mm in the end?

[Kash15]

What size is it?

@Kash15 different Sky hubs have had different power supplies while you maybe lucky there is no standard regarding barrel connectors. Using a mains extension is far safer. The white Sky hubs up until recently had a USB-C connection which can be used to provide power.

If you do insist on a low voltage extension, the easiest way to size the plugs is to use a set of metric drill bits as gauges.

If a 3mm bit fits, it’s a 3.0mm plug.  If not try a 2.5 bit.  If that doesn’t fit, it’s almost certainly a 2.1mm plug.
