I got a small 3-speed cordless fan for around $14 which perfectly satisfies a need to quietly ciculate a little extra air under my laptop.
It is driven by a lithium ion batterywhich is rechargeable by connecting the fan to a USB charging station or a USB port on the laptop. The cable used is an "80CM USB."

A single pushbutton control gives on, off, low, medum, and high speeds. There is a power on light and a charging light which blinks while recharging and glows steady when fully charged.
Can I keep the charging cable plugged in to the computer (or line-to-USB charging device) at all times, or do I have to be aware of the charge state while it's plugged in and unplug it when fully charged? In my ignorance, I'm leery of anything with lithium in it, including hydrogen bombs, but especially lithium batteries.
