FYI: avoid using this on a laptop's USB ports. On USB 2.0, max current is 0.5A at 5V, making this a very underpowered 2.5W fan (USB 3.0 goes up to almost 5W). For reference, the slightly larger "air circulators" that typically go on sale here for about $8 consume about 90W of power. So if you want a lot more cooling power for slightly less $$$ and you have access to a power outlet, you're better off with one of those units.
