Light dimmers. One mechanical and several electronic ones with touch panels. None known to not work.
3 x Mini USB mobile phone charging bases.
3 x Apple AirPort A1088 Expresses and 2 x USB chargers and 1 other USB charger.
I think the USB chargers have failed as has one of the AirPorts (these may or may not be recoverable, I've not tried) but the other 2 AirPorts seem to work fine.
Would prefer all collected together. Available almost any time.
A number of household/electronic items (Old Slade KT16)
