Learn how easy it is to construct a cell phone charger, which could charge your cell phone battery from the comfort of your vehicle itself anytime, anywhere.
Cell phones are getting to be so indispensable that it really is so difficult to steer a life without these smart gadgets. We have already brought up the working of cell phones in our previous article. But one big drawback (for pessimists) with these mobile phones is their battery, with a limited supply some time and eventually gets discharged from a certain period of usage. Thus it should be recharged each time it gets flat.
eval(ez_write_tag([[468,60],'brighthubengineering_com-banner-1','ezslot_6']));Normally all cellular phones are provided using a charger of their own from the manufacturer itself. But these mobile phone chargers usually are meant to be used with the domestic AC outlets only, and cannot supply outdoors where an AC supply just isn't available (as an example during picnics, long tours, trekking, or even in the middle of your highway).
The present circuit with the dc to dc cellphone charger is particularly designed to provide in conjunction with a 12 volt automobile battery, or alternatively it can be permanently placed in your car or motor cycle as an emergency mobile phone charger.
The circuitry inside cell phones is sophisticated and advanced, therefore the internal parameters are very strict and sensitive, and also POC Resistance Mid the margin of error is narrowly confined. It absolutely won't charge unless and before charging voltage and current matches exactly with the internal guidelines.
Normally battery used in cell phones are of a 3.7 volt lithium-ion type and the current (AH) are vastly different with different models.

It is wired across the well-known 7805 voltage regulator IC, which single handedly performs the function of a perfect cellular phone charger.
Keeping the printed side of the IC facing us
The 7805 IC as well as configuration as described above are shown inside the picture with the IC inside the adjacent image. It will provide a clear idea for the reader in regards to what is being brought up.
This resistor does an important function of current limiting and restricts the flow of excess current in the phone. Without this the cellphone may not except the charge and can read "not charging." Connect 100?? /25v and a100nf capacitors to the input and the output with POC Resistance Mid the IC respectively to remove the voltage spikes and transients even though the vehicle is in motion.
Finally the entire circuit can be enclosed in the suitable plastic enclosure with two outlets for inputs and outputs each.
Though the circuit of the DC cellular phone charger described POC Resistance Mid 3-Qtr Jersey - 3/4 Sleeve - Men's Online Cheap above using the 7805 IC might appear to be over simple, however the charger created from this circuit is surely full of several salient features. They are as follows:
1) Excellent voltage/current regulation.
2) Current limited to a safe value,
3) Cell phone battery can't ever be overcharged,
4) The IC 7805 is thermally and short circuit protected thus your entire circuit is virtually indestructible.
