Question :

I have an old Umax SOHO 1OHO8 ethernet switch that I would like to use in my LAN-network, but the power adapter has a very strange problem : one of the pins that go into the wall power outlet has come loose, and now ‘retracts’ whenever I plug the power outlet.

I already tried gluing the pin back into the power adapter with superglue, but I can’t fasten it, so it keeps coming loose. I also tried using an adapter plug, but I couldn’t find one that enabled me to keep the pin from retracting…

What can I do to fix this ?

Answer :

Just buy a new one.

You probably won’t be able to find the original one, but you will be able to find a new generic one with the correct specs.

The specs of the Umax SOHO 1OHO8 power adapter are :

• AC input 230V (so 100-240V will do)
• DC output 7.5V 1A (= 1000mA)
• output plug/pin 5.5×2.1mm (= 5.5mm outside diameter & 2.1mm opening diameter inside)
• output plug/pin polarity : MINUS outside & PLUS inside

You can get a US-version replacement here : US power adapter 7.5V 1A 5.5×2.1mm

You can get a UK-version replacement here : UK power adapter 7.5V 1A 5.5×2.1mm

You can get a EU-version replacement here : EU power adapter 7.5V 1A 5.5×2.1mm  (note that this one actually has a 5.5×2.5mm plug that is compatible with 5.5×2.1mm)

enjoy !
