I knew the DC-AC power inverter connected to the cigar lighter socket, but I thought that was too expensive to buy.
I went to the "Life-improvement commitee"'s off line meeting in Akihabara and went shopping to past T-zone minami and found this...
Small body, black sharp design and more, very cheap price of 4,980yen....(It was a matter of course, because it was in the junk corner)
I have no reason to hesitate to buy.
From then I have used it for a long time. I changed PC such as:530>>110>>535....but this "little power supply under the floor" worked without a break for long years....
When I changed notebookPC for TransNote, I saw the label of AC-DC daptor....
"Input:100-240V 1.4-0.7A"
It's very short of power for this adaptor...
"But, it may be all right..."
So I used it for half an year....one day I found the fuse of this inverter was cut off.
I changed it and connected it to the cigar lighter....there are lightning and came "smoke"....
I think he died for overwork....
