Tools and Supplies:
Radio Shack Adaptaplug M
Radio Shack AC-to-DC Power Adapter 5voc to 3.5A 

The Ninja Cooling Fan works very well. The body is an all aluminum and has two cooling fans that provide enough air to cool down this laptop. The one problem is with powered by USB (Universal Serial Bus) via provided T-adapter cord. The T-adapter breaks during constant use. The T-adapter can be purchased for $7 but if it keep breaking than this is not a solution. Once the T-adapter can be ordered but it comes from China. The solution is to plug the power cord directly from the back of the cooling fan and not use a USB port. 

In this post another alternative use of the power outlet adapter instead of the USB T-adapter port plug. 

This post shows the four steps to power the laptop using an Radio Shack AC-to-DC Power Adapter and an Adaptaplug-M.
