Tech on the Go Meets the Cooler Master SNA 95 Notebook Adapter

Performance
Performance testing for the SNA 95 was accomplished by substituting the regular power supply for the following portable computers.

• MSI Wind U100 [MS-N011 netbook]
• HP Pavilion tx1000 [12.1-inch tablet PC]
• Dell Latitude D930 [15-inch notebook]

I used the SNA with each of these for a total of one week and measured the SNA 95's ability to charge, maintain power and also for convenience over the standard charger. To add an interesting extra to this test I used the SNA 95 to maintain the charge in an iPhone 3G for each week of testing. The iPhone was connected during operation [while the laptops were running] Each laptop was run on battery until it went into hibernation/standby mode.  I then plugged in the system and continued to run it while allowing the SNA to charge the device. At the same time I plugged in the iPhone 3G. I also tested and compared the SNA 95 to USB charging from a PC and from the Apple provided Adapter.

As you can see the SNA 95 performs very well and  in many cases out performs the stock charger that is provided with the actual device. It is good to see that the USB charger was able to charge the iPhone 3G while charging the notebook with less than one minute delay after the stock charger. But the efficiently of SNA 95 is also proven with the fact that it took a regular USB port on a high-end motherboard 14 minutes more for the same work.
