This document describes a solar powered mobile phone charger. It consists of a solar panel that converts sunlight into direct current (DC) which is then used to charge the internal rechargeable battery of the charger. This battery can then be used to charge mobile phones when needed, allowing phones to be charged using solar power even in locations without electricity. Some benefits of this solar mobile charger are that it provides a clean, renewable energy source to charge phones and can be used in emergencies or locations where electricity is not available.

2. INTRODUCTION
Though the years, technology has allowed the cellular phone
to shrink not only the size of the Ics, but also the batteries.
However, as technology has advanced and made our phone
smaller and easier to use we still have one of the original
problem that we must plug the phones into the walls in order
to recharge the battery. Most people accept the reality as
there is no other option to this problem so they carry extra
batteries with them.

3. Every time it is not possible to charge mobile batteries
everywhere at any time so we design this mobile charger
from which we can charge the mobile battery anywhere at
any time. In this project we are using the concept of
energy harvesting by using solar energy for battery
charging purpose. By using this we can charge our mobile
battery in remote areas where there is a problem of
electricity. Cost of this circuitry can be reduced to certain
extend so that common man can easily purchase that and
get benefit from that.

4. What is a Solar Mobile Charger?
A solar mobile charger is a device that is empowered to
charge a mobile phone using solar energy. The device is
produced with a solar panel that charges its battery.
This battery is rechargeable. It stores the power that is
needed to charge a cell phone when needed.

5. How solar-powered cell phone charger works?
This charger has a solar panel that receives sunlight and
converts it into a direct current (DC).
You need direct current to charge your phone so you
can charge your phone using the direct current
produced by solar panels without any hassle.

6. OBJECTIVES
• Describe the purposes and power of solar panel
• Explain how solar works
• Identify the benefits of this experiment

7. PURPOSES
This feature makes it possible for the charger to power
any phone, all you need is some sunlight and some of
these handy devices on our experiment.
When using a solar phone charger it does not require
any other power source. All it takes is sunlight. So we
can get a lot of benefits from using a solar power
charger.

8. MATERIALS
• Solar Panel
• DC Buck Converter
• DC Female Jack
• Wires
• Connector

9. BENEFITS
What are the benefits of using a solar powered mobile
charger?
Mobile phones can be a real lifesaver in emergency
circumstances.
There are many benefits of this experiment, this are the
following:

10. •Durable and lightweight
•Clean Renewable Energy
Source
•safe and reliable to use
•Reduce the electricity bill
•Ability to charge your
phone where electricity is
difficult to obtain
•Solar power depends on
the weather
•Expensive than the
standard charger
•The charging capacity
depends on the size of the
panel in the charger
DISADVANTAGES
ADVANTAGES

11. CONCLUSION
Solar chargers are a must-have item for everyday use
and can provide some of the best experiences out
there. They can charge your devices while at the same
time giving you the opportunity to help the
environment and contribute to a greener world.
The best part about solar chargers is that they are
lightweight and durable, so they can easily be taken on
trips or to work.

12. Clearly, using solar energy as an alternative to
electricity is a great idea due to the many advantages
that come into play. Solar mobile chargers are
convenient, portable, easy to use, and versatile.
