Charger killed my monitor

Yes, I'm foolish. I've been warned about plugging in chargers directly into devices. One almost killed my laptop last year and today, as I screwed in my 510 into its charger, there was a hiss, pop and my beautiful 24" LCD died.

I'm not exactly bothered by the loss of the monitor, its 4 years old and I've been trying to find a replacement. But what does bother me is an observation I made about the charger itself.

I have 4 chargers. 1 in a draw that doesn't work and 3 that were great.

Today though after the incident, I noticed that one of the chargers has a small metallic piece missing from the center, which left behind a very small hole where it has previously been. It was an easy comparison to make. Also, to my surprise, the broken charger in the draw has that exact same piece missing.

Guess I have couple of questions now, to ensure future safety.

#1. What do you suppose the charger would have done to the monitor? (Besides shortening some connection) - and is it something that likely to be repairable?

#2. Are all usb wall chargers created equally? Do they all carry the same charge?
I figure I'll run down to radioshack and purchase an additional wall charger, but I want to ensure I don't need to Joye specific one.

#3. I was reading about the battery safety overall. It's possible for the battery to explode or catch fire. Sounds kind of sketchy when its 2 inches from your face. But while the lithium ion is housed in a metal case, what's the likelihood that it would cause injury?

Please link. If this is a different somehow than a basic USB hub (which usually is just used as a single port extender and multiplier) then I'm not sure what you're referring to exactly. And I'm an IT guy! :)

Here is an example of a 2amp mains to usb adapter that can be used for passthroughs:

2 amp AC to USB Adapter, ideal for Passthroughs

But for a charger you would need to make sure you have the proper DC out voltage for your model of charger. There is a very good chance you can buy something that fits the specs locally. Alternatively you could contact your vendor and ask about getting a mains plug for your charger.

You should take oldsoldiers advice. That wall plug should work fine with your charger as it is a usb charger so it will be 5v and it will draw the current it needs which will be under 2A.

What is happening with connecting it to your monitor and laptop is the usb charger is drawing more current than the usb connection you are using is designed to provide. This results in bad things happening - generally a burnt circuit board that provides the usb power in the monitor or in the case of the laptop or a desktop computer probably burning out components on the motherboard. Most computer usb ports are not designed to supply more than .5mA.

Yis, a computer/monitor USB port is designed to output 500ma.
Us ace backwards americans would refer to a "mains charger" as a wall charger (one that plugs into the wall outlet, like your ipod charger, or similar). I can say that I have many wall chargers lying around (ipod, cell phone, e-cig, etc), and none of them have a problem charging my riva. I even have cheap car adapters that haven't had a problem yet.

And your monitor can probably be fixed fairly affordably, if your tv repairman isn't a rip off artist. I know my tv guy would charge me $75-$150 including parts and labor to fix something like that, probably less.
