Okay well I sort of volunteered to investigate this for a workmate. They don't have a computer at their house and want to be able to charge the nano.
So I said I'd look into it. Now there is the ever so simple option of a plugpack that is terminated with USB. Now 2 problems I have with that, 1 can't easily get inline sockets so making one up out of a PCB mount one would be somewhat dodgy although quite doable. More important problem to me is that I'm concerned with noise and spikes going to the nano and also what happens if something goes wrong. I know the plug packs usually have short circuit, thermal protection etc. but what if the plug pack itself bit the dust.
So then that got my thinking of making up a little filter/protection circuitry in a project box. Maybe an inductor, cap, MOV etc. One protection I've heard of is a 5.1V zener with a 5.6 or 6V plugpack then a fuse. Maybe substitute in a polyswitch instead of the fuse as this person isn't tech savvy at all.
Any thoughts ?
Ideally it will be using components that won't get too hot as it will have to be in a fairly sealed up box, to reduce the chances of things breaking. I was thinking about a regulator but then thought it may get toasty and isn't really needed
