Portable Mobile Charger

This document outlines a portable mobile charger project. It aims to build a charger that can be easily carried and used to charge mobiles in emergencies or when the battery is low. The charger would consist of a battery source of 9V or above, a regulator circuit to provide a stable 5V output, and a USB port for charging phones. It would allow phones to be charged wirelessly from up to unlimited distances, providing flexibility to charge anywhere needed. The portable charger could be useful for emergency calls and the public.

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
