Connect SLA batteries in parallel, get a proprietary smart charger. connect up...done. I also added a diode in the supply to the router to drop the voltage a tad, but not absolutely necessary. The second photo shows the charger, the grey thing with an orange light showing.

1372715 2014-04-15 01:19:00 So hypothetical situation here (Coz I don't understand power-math).

If I had this:

Power dies. It's only powering this:
pbtech.co.nz

How long would you expect it to run for before it dies?

Cheers


Chill.

You might run into another issue: some routers will turn themselves off on a very small load, like a router.
