Cheap USB Fan Speed Controller Test & Review - from AliExpress for less than $1

This is a cheap 80p(!) fan speed controller I bought recently from AliExpress. It connects between a power source (like your laptop USB socket) and a desktop fan. It's limited to 5W output, but that should be more than enough. If you're looking for this, the listing is titled: 'DC 4V-12V 5W XY-FS USB Fan Stepless Governor USB Fan Speed Controller Multi-Gear Auxiliary Cooling Tool'. If you're in the UK, you should visit TopCashback before placing an AliExpress order.. they're currently offering 8% cashback! https://www.topcashback.co.uk/ref/mat... UPDATE; one thing to note is that I plugged in a neat little USB power monitor (also bought from AliExpress some time ago) and you can see the voltage change.. it can be so low that it doesn't power the meter, and the voltage can actually go way over 5v, so you have to be careful not to damage whatever you've got connected. As noted by 'bummers' in the comments, this means it's using a voltage potentiometer (rather than pwm). I only recommend products I buy & would use myself, and all opinions expressed here are my own.
