I have a lot of old mains adapters, accumulated over the years, that might be of use to someone, plus some other bits and pieces.
NOTE: I have not measured the sizes (outside diameter and pin diameter) of any barrel connectors: there are many possible combinations!
So if you think you might want a particular item and know what size connector you need I will try and measure it. Or just come and take your chances.
Phone chargers:
Nokia 5V with micro barrel connector.
Nokia 3.3V with mini barrel connector. 2 of these.
SonyEricsson 5V with the weird SE connector.
Laptop PSUs:
LITEON 19V x 3.42A (65W) with barrel connector. 2 of these.
HIPRO 19V x 3.42A (65W) with barrel connector.
HP 19V x 4.74A (90W) with HP style large barrel connector with central pin. Unlikely to fit anything but an HP machine.
HP 19.5V x 2.05A (40W) with barrel connector.
Miscellaneous plug top adapters:
Thomson 15V x 1.2A with barrel connector.
Netgear 12V x 0.5A with barrel connector.
Unbranded 5V x 1A hard wired to an old smart meter display. Someone competent could cut that off and attach a connector of their choosing.
Powerbase 3V x 0.3A with barrel connector. This came with a Homebase electric screwdriver, which has gone the way of all old tech.
D-Link 5V x 3A with barrel connector.
Unbranded 6V x 0.8A with barrel connector.
Other hardware:
Netgear DG834G v4 ADSL router, with mains adapter.
D-Link DSH-5 5-port + uplink Ethernet switch, with mains adapter.
USB-A 4-port hub, self powered
USB-A keyboard. Cheap, small and lightweight
Various USB cables - no USB-C. If there's something particular you're after, ask and I'll see if I have it.
