Heated USB Keyboard

Posted on September 21, 2011 · Posted in Computer Accessories

Some weeks before Fathers Day, my father inlaw and I were on the couch talking about IT Techy type things. He mentioned, that an old laptop he had was still very good because of how warm it was for his fingers to type on. Then we decided how great it would be to have a heated keyboard, not even knowing if one existed. But Google came to our rescue and sure enough a heated keyboard exists. See this link for the Heated Computer Keyboard

As the USA supplier wouldn’t ship to Australia, and their isn’t a supplier here in Australia that I could purchase from, we decided to purchase the keyboard from the USA Supplier using the services of http://priceusa.com.au which were excellent to work with.

Plugging the keyboard USB cable into a computer allows the keyboard to work as any other multimedia USB keyboard would. But on the left top side of the keyboard is a socket for a plug pack and a switch to control the 2 level heating function.
Power to the heaters that are embedded in the keyboard comes from a plug pack that is plugged into the Mains Power socket. The plug pack that comes with this heated keyboard is a 120 VAC plug pack, and not suitable for Australian 240 VAC mains power.
So my Plan A was to buy a new 240 VAC plug pack to replace the 120 VAC from the USA but with the same output specifications. Unfortunately there was no info on the Internet to suggest what the output power specifications would be. When it arrived I found that the plug pack had a output specification of 20 VAC @ 1.8 A. An Australian equivalent of this plug pack is difficult to find. So much for Plan A.

I now had to come up with Plan B. I soon discovered that Jaycar sell a 50 VA Stepdown Transformer with a USA style socket to supply the needed ~120VAC for the plug pack.

So finally got it all plugged up, and thankfully it all works. The stepdown transformer plugged into the 240 VAC wall socket, the heated keyboard plug pack into the stepdown transformer and into the keyboard itself.
The heating function takes about 10 minutes to warm up and when it is running a LED is lit on the top left of the keyboard. There are 2 switch settings, for different heat levels. When the keyboard temperature reaches the correct temperature level for the selected setting, the light will switch off. The user instructions included with the keyboard don’t appear to be very clear, but it seems that heat level 1 is 93 degree Fahrenheit and heat level 2 is 100 degree Fahrenheit.

The total cost to us of this gift is about $200 AUD. As a business, Computer Troubleshooters Croydon do not intend to resell this keyboard to our customers. However if you want one of these keyboards we can provide a service to help you through the process of ordering it, obtaining the stepdown transformer and installing the keyboard for you.
