Question:

What makea a fast charge cellphone charger?

I have heard of fast charge cellphone chargers and was wondering what makes them faster? Im guessing the higher the output current (mA) the faster the charge? Am i right? The charger that came with my phone outputs 5V 700mA (0.7A) would a 5V 1200 mA (1.2A)charger charge it faster? does the cellphone have a max current it can draw? or will it blow if it is too high current?

Answer:

Fast charging requires a combination of things: The battery must be designed to tolerate fast charging (all rechargeable batteries can be charged slowly). The charger must be capable of much higher output current than a normal charger. The charging circuitry in the device (phone) must also be designed to provide fast charging, and since it, rather than the power supply, ultimately determines the charging current, using a 1.2A charger in place of a 700mA charger will probably make no difference at all in the rate at which your phone charges its battery. No damage should occur.

In case ur charger helps charging by applying way of USB and additionally you have an information cable in the %., connect the telephone to the computing device by technique of the documents cable and it will initiate charging.
