Battery powered DS help

No.

Fuses do not protect devices. They protect wires from a device failure. Note that the only way to blow a fuse is to draw too much current. The only way for the router to draw too much current is for it to fail. A fuse cannot protect the router from itself.

A fuse might protect against the application of too high a voltage, but only if the device's power input was designed to survive overvoltage and to draw lots of current in the process.

Anyone else lost a router?

We lost a protective switch earlier this year. We were using a cellphone power supply with the correct voltage rating, but a lower amperage rating. The switch tried to pull too much current, the cellphone power supply fried, and that fried the switch in turn.

It was a deperation move when we were at West Michigan and they announced they were out of DS's, and we only had 1 working port.

We'll be working on something a little more robust and easier to lug around than one of the 12V batteries...
