Shorting the Ends of a Mobile Phone Charger

[QwertyXP]

What would happen if I shorted the ends of a mobile phone charger (in both the cases when input is 110V or 220V)?

I was considering using the terminals of a charger as a dc source for any experiment I might want to do at home (batteries would be too expensive), and wondered whether it was a good idea.

Google is your friend. Here's a discussion (among dozens) that I found in about 2 seconds:

It's not good to short them. Some might deal with it fine, some may burn out, some may burn up. Personally I think using them for experimental power sources is fine, but keep within the limits on the case. I've never had one fail "violently", but I generally use them on reference design and evaluation test boards. I expect they will handle a momentary short without burning up if they have a UL or other safety rating, but they may fail. Others here may disagree about their safety.

Perhaps Google the specs and safety features of whatever model you are planning to use. Everyone is different.
