<div dir="ltr"><div class="gmail_default" style="font-family:garamond,serif;font-size:large">Kinda off topic: I had a power outage at home that lasted about 6 hours. After the power came on, I discovered that three wall warts (the ubiquitous plug-in transformers) were dead. As I hadn't used the devices that these wall warts powered all that often, it was days or weeks after the power outage that I found out so I'm not sure that the power being turned back on was the cause. Is it possible that it was? Note that several other transformers, notably Apple device chargers, were not affected. However, the ones that died were connected to devices (they were not powered on at the time) but the Apple chargers were not connected to anything.</div><div class="gmail_default" style="font-family:garamond,serif;font-size:large"><br></div><div class="gmail_default" style="font-family:garamond,serif;font-size:large">One of the ones that died powered my doorbell... which is why this is so curious.
