Electrical convertor for my wireles router is extremely hot when in use.

Is this normal? I'm in the UKand have three things plugged into the electrical socket on the wall. The first is the actual power supply adapter of the router which is fine in terms of temperature. This power supply is plugged into the a travel adapter convertor block and this is one that is really hot...I cant touch the black area on of the convertor for more than a few seconds. Its a brown travel adapter block thing Its what converts the voltage or something tor the UK, I dont think it should be this hot right? Although it only is hot on the back strip of the actual adapter and not all of it is this hot. I guess the black part of it is covered in some kind of coating to help reduce the temperature? But I'm still worried that it way too hot as the black part cant be touched for more than a few seconds. The travel adapter convertor is plugged into a socket convertor because UK uses three inputs for the electrical socket rather than two like everywhere else.The rotuer is a D Link 108ag wireless and probably from america. Its working fine and the comp has been on 24/7 for three weeks now since getting the router. But is it dangerous?

You'd probably want to pull the covers off it and check the circuitry. Many of the Linksys boxes can run from near 4 volts to nearly 25 volts (the limits are the drop-out voltage of the 3.3V regulator and the power supply input capacitor rating). No idea how Netgear is configured.

The nice thing about the Linksys boxes is that power supply current drops as the voltage rises, so line losses can be correspondingly lower.

Remind me sometime and I'll write up my "Power Over Cat5" conversion. Also, look for a thread titled "Linksys Lies!" 8*)

I know, that's why I asked if the actual current draw has been measured.

Lose the transformer, use a SMPS instead :)

Incidentally, did you mention somewhere that you'd run much more than the stated 5V into a Netgear ME102? Maybe it was a Linksys, can't remember now. I've just got hold of an ME102 but no PSU, I have plenty at home, particularly 9V ones but no PSU. My choices are either to buy a PSU or alternatively just bung a 7805 inside the unit somewhere.

Nor me yet. Like I said, I might just bung a 7805 in a spare 9V PSU and have done with it. :)

It's the early USB one, if I can't find a connector around the house then i'll just hard wire my bodged and 7805 equipped adaptor. :) Anything else and i'm liable to end up paying more for the thing than it's worth.
