Mono Monday - power

Still backblipping and have now uploaded photos of my last day at Parcevall Hall on 15/7 if you care to look.  Hot today and I found a box of items I brought from work when I retired - amongst them this small USB fan.  It was very cheap, but packs a fair bit of power so I thought it would be good for the Mono Monday challenge.  Having looked at the photo I am now going to take it apart and clean off all the accumulated dust!!  Thanks to Laurie for hosting.
