I went to a Apple store trying to get a "their fault free recall replacement" as this one was newer than all my other ones. they told me they could swap it with a factory refurbished one for $45-50 or I could buy a new one for $80. so what you think I did? I bought a ...
You can. All you need is an app such as NoSleep.
I have been getting tingling shocks from my Mac for a while, but only when I use the shorter cable i.e the converter is the plug itself. The problem stops when I use the extension cable. Must be design fault, with the shorter plug adapters not earthing properly.

If you device is not "identified", and did not make the request, it will get the 500mA.

A Thunderbolt port can provide up to 10W. That's enough to charge a phone or a tablet but definitely not a notebook. A Macbook (Air/Pro) needs between 45 and 90W.
The MBP is not a thunderbolt device; it is a laptop with its own power source, and a thunderbolt port. If you need to replace the power adapter for your MBP, then take care to obtain the correct wattage.
