I've been following the advice I gave for lots of years. It's safe and reliable. I probably have 20 tablets at any given time and about 8 ereaders and a number of MP3 players, phones, portable media players, etc. I live in a retirement home where my neighbors have a lot more devices. They also follow this same advice. Their devices and mine tend to last for years.

I agree in the general case, if you are careful and avoid crap or fake (dollar store) chargers, it is almost always okay to mix and match chargers. However, when charging expensive devices (like my $700 cellphone), I am careful to use its own charger whenever possible.
However, when charging my kindles in batches of about 50, I even used USB hubs as power-splitters, and whatever else I could scrounge up, to recharge the batch.
My post was not just because you said "every charger provides 5 volts, or very close to it" after I had already explained dangerous exceptions to that case, but also because absolutes makes me raise an eyebrow so high it hurts.
