ThermaPAK's catch phrase is "Be Green. Be Cool." After testing out their product and checking out their press conference, their heat-shifting laptop pad does seem like a much greener solution for hot laptops. I was sent a sample about a month ago and have been testing it out. Basically, it's a simple mat with a sort of egg-carton texture that you stick under your laptop. The mat absorbs heat from your laptop and helps it dissipate. The idea is to keep your laptop cooler so it lasts longer, without requiring yet another plug-in device.
I noticed a definite difference in how cool my laptop stays when using the mat, especially in the first few hours. While I haven't measured the degree change to know precisely how well it's working for my laptop, I have to say I'm pretty satisfied with it. ThermaPAK says it can cool a laptop by as much as 11 degrees Fahrenheit. For my rather old, over-used, and usually hot laptop, it seems to work well, which is good for me because I want this thing to last a lot longer.
You don't have to refrigerate it, you don't have to plug it in, and you don't have to worry about it wearing out for a long, long time.
My biggest question was, "What's inside?" ThermaPAK uses sodium sulfate decahydrate in its interior, which is a relatively safe substance as long as you don't try to eat your mat, and the fact that you don't need to plug it in, don't have moving parts that break, don't have a battery or anything else that creates e-waste means that it's a greener solution for cooling laptops and helping to extend their life spans. Check out more of how it works here, along with more extensive reviews.
