Now then! I have a few supersonic cat scarers in the garden to stop them from laying landlines on my lawn. Currently each scarer eats through 2x 9v batteries every month or so.. Which is getting expensive! They do have an option for powering then with a 9v DC, 500ma mains adapter. The problem being that their official adapter only supports one device per adapter, and I don't want a bank of low draw devices taking up all my spare sockets!!
Apparently they draw way less than the 500ma.
Will it be possible to buy a 3rd party adapter, and wire several of them up from it in parallel? If I did, would I need more than 9v or more milliamps?
I have a relatively large garden too, so we're talking 40m of wire taking the 9v to them. I was thinking bell or alarm wire. Will I also need to account for these long runs in my calcs.
I'm pretty sure it's a simple calculation, but can't remember enough of my A-level physics!!
Cheers
