Powering a router During a power cut, using USB from a laptop.

post #1 of 6
Thread Starter 
What converter would i need to do this?
got the council coming round to do rewiring work and i still want to keep access to the internet.
i'm think that a USB adapter exists to go to the relevant plug needed to power the router (a bt homehub)
anyone got any ideas on the what the plug type for that would be?

And what about keeping your modem on? Are you DSL or cable? When your power is cut, is your cable linked? The router isn't what confers internet, it's the modem. Not to mention you are hardly giving us enough information. What type of router?

I assuming they are rewiring power and not data lines?

USB only outputs 2.5w.... that may not be enough to power router.

Just get a UPS.
Once again...

bt home hub 1.5




Ducky you sure about that?
unless i've read something wrong http://en.wikipedia.org/wiki/USB#Power says its 1.8A*5.25V which equals 9.45W which is enough to power the bt homehub 1.5 (7 watt)

I'd agree with Duckie...just invest in a UPS for the router/modem and remove a questionable part from the equation.

Does your router also terminate your WAN connection? Or do you have a device infront of it? If you can power a modem and/or a router I guess it would work assuming there is no issue with the ISP coverage. You should get the proper power equipment.

You will have to make sure that if you try this your matching the input spec for amperage and voltage so you may/most likely have to craft your own power adapter. While you may be ok with the wattage, if it only expects .5A (example) and you give it 1.8, thats probably not going to fly. Same for voltage, you need to make sure it within the rated spec other wise it might now power up, you might fry it, or it might operate strangely.
