PORTABLE MOBILE CHARGER
VISION OF OUR PROJECT : Our objective is to build a portable USB
charger for mobile phones. A fully charged phone may last its
battery up to 5 to 8 hours depending on how it is used. There is an
alternate method to charge up the mobile battery when the power
source is not available. USB was very useful in replacing the wired
interface ports.
DESCRIPTION : A good charger has an output of 4V DC to 8V DC and
a current capacity of 100mA up to 500mA.With this charger capacity,
standard 3.7V at 850mA battery can be charged up to 2 hours to 4
hours. Now we have come up with a solution new portable mobile
charger which we can carry easily and charge our mobile in
emergency conditions or whenever mobile is running out of
charge.
PORTABLE MOBILE CHARGER
The wireless charger will convert the RF/microwave frequency
signal into a DC signal, and then store the power into an mobile
phone battery
PORTABLE MOBILE CHARGER WORKING : Portable mobile charger
consists of battery source usually of 9V and above followed by a
regulator circuit of 5V at the input to the circuit it consists of
a Capacitive filter to avoid any repels from the battery. Pin1 is
input where 9V is applied and pin2 is common for both input and
output and pin3 is output pin which gives an constant output
voltage of 5volts. An LED indicator is provided for indication of
output. The circuit diagram is shown in figure. This charger is
provided with a U.S.B port which is suitable for any mobile which
makes comfortable and ease of usage.
Advantages: Lower risk of electrical shock or shorting out when
wet because there are no exposed conductors
Do not depend on Power from outside
Unlimited distance means flexible to move anywhere where we want
at that place charge the mobile
Applications: Public
For emergency calls
Conclusion:
The device application can be used for wireless charge up the
batteries which can save power,time and money in a long run for the
general public
