I forgot my 5V/2.1A charger at work and I only have a 5V/1A charger at home. I tried plugging in the device and it seems to work (battery is loading).
Theoretically speaking, what bad things could happen? (E.g. could the charger start to burn because more current is being drawn than it can handle?)
Practially speaking, what problems should I expect and what can I do to avoid them? (e.g. check if charger is getting hot?)
(In case it matters, the device is a Galaxy Tab 2, the 2.1A charger is the original charger and the 1A charger is my iPhone charger. Both convert 220V AC to 5V DC (USB).)
