Clamshell type of charger can last longer as they have protective covering over the solar cells.

1. Solar Phone Charger - Create Your Own Reliable Source of Energy
Solar phone charger is used for charging batteries without depending on electricity. These
chargers work when placed under the sunlight and it can charge both lead and Ni-Cd batteries.
The principle with which the charger works is very simple. It absorbs the solar energy and
converts it into electrical energy which is transferred to the battery through the charger.
There are three major benefits for the users while using solar chargers.
 They can be used in emergency situations like when there is a power outage or while
traveling. Batteries can be charged from anywhere and at anytime as long as there is
some sunlight.
 Solar power is renewable source of energy and hence it is environment friendly. There
are no fuel wastes or byproducts while using this energy source.
 There are cost effective chargers. Even though the initial cost for the chargers may be a
little expensive, repair and maintenance costs are reduced significantly for these chargers.
The Solar Powered Iphone Charger can be created with the help of few simple components that
are available in the market.
 Solar panel is the most essential component for making these chargers. The panel consists
of two wires at the back, positive and negative.
 Voltage regulator is a circuit that contains one IC7805, two 100µF and one 10µF. The
input from the solar panel should be connected to the voltage regulator. All the
components of the regulatory circuit should be smoldered together.
 This circuit is connected to the USB for receiving the output.
The circuit can be tested by placing it in the sunlight and measuring the output which has to be
about 5V. Mobile phones can be connected to the charger through the USB port with the USB
cable for the process of charging. The Solar cellphone charger should be placed towards the
sunlight in order to get continuous input.
The solar cells are available in a wide range of sizes and shapes. Some panels flip open while
some can be folded and rolled. They are small and lightweight for people to carry around with

2. them. As a matter of fact, portability is one of major advantages for choosing these solar
powered chargers over electric chargers.
There are a few tips for choosing the right solar panel phone charger.
 The phone should be compatible with the plug of the solar charger. Most of the phones
have USB connectivity which can be used for connecting the solar charger.
 The solar panels should contain more number of solar cells in order to produce more
watts power for charging the phones quickly.
 Clamshell type of charger can last longer as they have protective covering over the solar
cells.
It is necessary for the users to compare the technical specifications and the prices among the
various Solar Powered Lanterns before deciding to purchase the best one available.
