We had a two-hour power cut this morning, which also affected the only local cell tower. There was no mains power and no cell signal, so I couldn't use tethering as I can when the power cut is less widespread. Fortunately, I had a Maplin universal charger which has a mains input and a 12V input. I had recently bought a small, 7AH motorcycle battery. My modem/router uses about 14 to 18 Watts and this would have given me about 5 hour's use. The Maplin device can output voltages of 12, 15, 16, 18, 19, 20, 22 and 24. I guess it will maintain the 12V my router needs, even as the battery voltage falls below 12.
Unfortunately the N40HJ is no longer sold and the similar model does not have a 12V input.
This has inputs of 12V dc, 120V and 240V dc.
