Seriously...How often does that happen
LOL!!!
More often than we'd like, unfortunately. All it takes is some high wind and the power can be knocked out for hours. We usually get hit several times during the winter storm season.
During the summer heat when everyone's cranking the A/C it often goes out as well. The power companies have a "flex your power" ad campaign to discourage people from running appliances unnecessarily during peak usage times (e.g., wait til off-peak hours to run your washer, dryer, dishwasher, etc.).
Then there are "rolling blackouts" where they cut power to certain areas for a few hours to keep a grid from being overloaded when demand is particularly high. They give no warning or notice. Sucks to get stuck in an elevator when one happens.
Our house is 100 years old and the electrical infrastructure in the neighborhood is even older. We seem to be in a particularly bad spot on the grid, as often when it's dark here you can see that lights are on a block away.

Oh, yeah, and the Eno 3000 tuner does both clip and mic with settings for chromatic, guitar, bass and violin. The only negative comment I've ever seen about it is that it's a tad bulkier than some of the more expensive clip-only ones that don't even offer a mic feature. At $20 I think it's a real bargain.
Edit to say:
Pros - Even though it may be slightly bulkier than a tuner that doesn't even have a mic funtion, it's still a fraction of the size/weight of my old trusty Boss TU-12, which is like a brick in comparison. Plus, it's straight on accurate when compared to the Boss. Mine also came with a spare battery.
Con - I wish it came with some kind of protective covering or carrier case to keep the display from the possibility of being scratched, but I had an extra drawstring Oakley sunglass pouch which is perfect for it. The fabric is made to not scratch a delicate surface, so you can use the pouch to wipe off any accidental fingerprints.
