No, it won't. Basically, plugs are one-way streets. Electricity frow out of them, but you can't "charge the power company." So the phone can charge, but if the power goes out, and it's still plugged in, it won't discharge any faster than normal, since the power has no where to go except to power the phone.
To charge an RC helicopter using a mobile charger, you need to ensure that the helicopter's battery is compatible with the charger's output voltage and connector type. Use a USB adapter that matches the helicopter’s charging requirements, often a USB to micro USB or similar connector. Connect the mobile charger to the helicopter's battery charging port, and make sure the charger is plugged into a power source. Monitor the charging process to avoid overcharging, and disconnect the charger once the battery is fully charged.
When you're charging a battery, you're pushing electric energy back into the battery. But not all energy is taken up by the battery. Some turns into heat.
One of the newest ways to recharge a mobile device or a battery is to use a battery charging pad, although it might not be obvious how it actually works. Basically, a battery charging pad creates an electromagnetic field that is oscillating at a specific frequency. The device or battery on top of the pad has a small coil inside that is attuned to this frequency, and generates electricity when exposed to the field the pad is generating. Using this method makes it possible to charge a battery without requiring it to be physically plugged into an outlet.

I believe you are referring to charging a mobile phone. If this is the case, mobile phones change their charging technique at something like when they are 90% full. Instead of being in full charging mode, they switch to trickle charging mode. This is an effective means to charge a battery over a long period of time without hurting the battery- i.e. if you accidentally leave your phone charging all weekend, instead of the required 2 hours.
Two pins for charging the battery, using the electricity and one acts as a temperature sensor; which indicates battery's temperature.
The time it takes to charge a 3.8V mobile battery depends on its capacity (measured in mAh) and the charging current provided by the charger. For example, if you have a 3000mAh battery and use a 1A charger, it would take approximately 3 hours to fully charge, assuming 100% efficiency. However, factors like battery health, charger efficiency, and charging speed limitations can affect the actual charging time.
There is no secret code. Simply plug in the appropriate charger.
a charger for the battery is provided along with the car it almost same as charging your mobile phone
Most say 24 hours for the first initial charge.
