Why Do Mobile Chargers and other electronic chargers have strange pins, unlike plugs?
So that APPLE can charge $30 for a charger that should cost $3.99! Its purely MARKETING.
can i use it to charge the Gadget?
The current is the MAXIMUM current it can give, so you can use a 5.7v 500mA charger instead of a 5.7 350mA charger.
If the voltage is less, then it can't be used (probably, depending on the application).
A
Too low current, and the charger will probably overheat.
Too low voltage, and the gadget probably won't work, although a low voltage is not going to damage it.
If the current rating of the new charger is 350/500 of the original charger, then it will take 500/350 ~= 1.5 times longer to charge the appliance.
though 6V might be used? what do u say?
Then the battery may not charge at all. The voltage requirements for properly charging a battery are determined by the electrochemistry of the battery. If the voltage doesn't reach the potentials required by the chemical reactions, no charging takes place.What if the Voltage is 5V/ 5.7 IS OF ORIGINAL CHARGER?

Another Ques: Is the Voltage of Slightly Discharged Battery same as that of Charged Battery?
I ask this because i found no difference b/w them; then how does charging take place without the difference in Voltage (Back EMF).
