This is a truly handy and unique item in my opinion. Wish I had thought of it.

2. Adapter works well. For the fan connectors only 2 pins (out of the 4) are used and available, so fans are always running, no ability to control the fan speed but that is not what I personally need.
3. Adapter is universal; Input: 100-240V; output 12V@1A. Keep in mind that having 2x fans connected will split the amperage (500mA each).
4. Has a nice green LED indicator to indicate that there is power applied
5. Construction seems solid enough. Decent thickness cables (30mm, ~1.18")
6. Sticker mentions model 1210
7. As shown in the pictures this is actually two devices. A 12V@1A power supply with a female 2mm connector, AND a male-adapter with a 2x PC fan header. Both devices have future potential use.
