21 Century Hands-on Production Of Solar Cell Phone Charger

DIY solar power is surprisingly simple to apply in making your own solar powered mobile phone charger. With the increasing popularity of alternate energy sources, solar powered phone chargers are a lovely option for green living. Commercial solar mobile phone chargers can be pricey, so this do-it-yourself project is an economical money-saving option. You can simply put together this type of do-it-yourself charger with common items found around the house and at the local hardware store.

Tools and Materials

• 6 volt solar cell battery
• Small metal box, about 5x2 inches 
• 12 volt cell phone charger
• Electrical tape 
• Voltage meter
• Velcro with adhesive backing 
• Soldering iron (at least 15 watts)
• Small paint brush 
• Solder 
• Flux

Step 1 - Prepare Solar Cell Battery
in the event you run in to difficulty finding the correct solar cell battery, you can simply recycle one from a little LED light. Be certain to remove all plastic backing from the battery in the event you choose to go this route. Check the solar cell battery with the voltage meter for positive and negative polarity, and mark each + and - with a little piece of tape.

it is important to accurately gauge the voltage with this meter to keep away from shorting out your mobile phone. in the event you aren't sure how to make use of your voltage meter, ask your hardware retailer for a demonstration, and be certain to read all the meter instructions. Also mark the positive battery wire with another piece of tape, and then cut this wire in half so that one finish can be fitted to the mobile phone charger.

Step 2 - Prepare Metal Box
A little metal box that works perfectly for this project is an Altoids tin. Cover the inside of the tin with strips of electrical tape to prevent feasible shorts. Carefully solder the charger wires to the solar cell; attaching positive to positive and negative to negative. Since these you are working with electrical parts, using lead based solder is a commonly accepted practice. Be certain you brush the wires with a lovely flux before soldering as well.

Step 3 - Attach Solar Cell Battery
Use the Velcro pieces to attach the solar cell battery to the top of the tin lid. Stick one piece of Velcro to the middle of the lid and one piece to the middle of the solar cell. The Velcro pieces allow for simple replacement if the solar cell battery ever needs it. Be certain to cover any exposed wires and contact points with more electrical tape. Velcro your solar cell battery and tin box lid together and plug in your mobile phone at the other finish. Leave it to charge in a sunlit area for several hours.

An advantage of this solar phone charger is that it is simply transportable and will fit in to a purse or bag right along along with your mobile phone. This solar powered charger has even been found to work under strong indoor light. In case of a power failure, you will still have mobile phone power and won't be cut off from relatives and friends due to a dead phone that cannot be charged from an electrical outlet.

How to Choose a Solar Iphone Charger

With the rapid growth in the environment-conscious, solar chargers are growing in popularity. More and more people want to know how to choose a good solar charger for your small electronic devices. The following are some tips to learn from my experience
There are many solar chargers on the market. They vary in size, shape and function. For this reason, choosing the correct charger for your devices can often be difficult and confusing. There are several factors to consider before buying a charger. Some of them are discussed below.
The size and power
There is usually a correlation between the size of the charger and the amount of energy it can generate. The larger the solar panel, solar cells that can hold more, and the more power it can produce.
When deciding on the size of your boot, you must take into account the devices to be loaded. If only iPhone battery charging, the battery of your camera, or other small mobile device, then a small charger will suffice. But if you charge your laptop or your refrigerator, you will need a bigger boot.
Charging time
The charging time depends on the size of the charger. In general, though not always, smaller shippers will generate less energy than large shippers given an equal amount of time.
Support
Your mobile phone, camera and laptop require different plugs and different supply voltages. Portable chargers usually come with various plugs and adapters. In determining that the charger is best for you, check plugs and adapters different charger each can contain.
Trip Plans
Your travel plans will also influence the type of charger you can use. If you are traveling on foot, camping or hiking, for example, a large magazine it difficult. A charger small, light weight is the best option for you in these conditions. Conversely, if you travel by car you can afford to carry a larger charger.
Water resistance and heat tolerance
This is also determined by their travel plans. If you are planning to use the charger in your car, you will require a charger with a high tolerance for heat as temperatures inside cars can become very hot. On the other hand, if there is a possibility that you and your charger may be exposed to water, then you should opt for a waterproof boot.
Cost
Choose a charger that fits your budget. You’ll need to compare different options, weigh the pros and cons of each magazine to make an informed decision.

How to select a solar charger for your mobile phone

A popular eco-friendly  way to keep your mobile phone charged is with a solar charger.
Most of us are confused by the available variety of these solar powered battery chargers, so what do you need to know before you choose one?
There a two important considerations

How powerful does the solar charger need to be?

Look at the nameplate data on the original charger, the one that came with the mobile phone. Read the part that states the output DC volts and milliamps, for example it may have OUTPUT DC 5.0 volts  900mA. This tells us the charger  provides a voltage of 5 volts, so the solar charger must be capable of providing 5 volts output as well.
You can use a charger that puts out a bit more voltage, say 5.5 volts or 6 volts but not less than 5 volts.
Why? ok here's a basic lesson in electricity: Volts is the pressure of the electricity in the wire. Let's compare electricity to water. Imagine you have long garden hose and you are trying to fill a water tank on a hill high above the  tap, now if the pressure of the water system is too low you won't be able to fill the tank because the system water pressure is too low to push the water up the hill, it's the same thing with electricity if the voltage (electrical pressure) is too low it wont flow through the circuit.
Amps is the current flow. Getting back to our garden hose, this can be compared to water flowing through the hose, A high water flow will fill the water tank sooner. Therefore a higher  amperage will recharge your battery sooner. A solar charger that supplies more amps is preferable to one that might supply the same voltage but a lower amperage.
A very high amperage can burn out the electronic circuit, but with solar cells that's not a problem because they are too small to provide a high current flow.
Ok, here's a quick lesson in photovoltaics:  All solar cells provide about 0.5 volts, that's a matter of physics, so to get 6 volts twelve cells are connected together like beads on a string. This string of cells might only provide 0.1 amps (100mA) The solar cells are glued to a backing board and there you have solar panel. The power (Watts) this solar panel can generate is calculated by multiplying the volts times the amps. so 0.1 x 6 = 0.6 watts (600mW)
Remember our garden hose? that's like the quantity of water it can provide in certain tome so water pressure times water rate of flow equals the quantity of water in given time and Volts X Amps = Watts, same thing! simple Hey!

What cable and connectors do you need

All solar chargers come with several adaptors to fit various mobile phones and also other popular personal electronics like Ipods, iphones and MP4 devices. Look at the wide range of solar charger adaptor tips that are available. The good news is the later model mobile phones are standardizing their power adapter tips, this will make your selection easier. The modern trend is toward the micro- USB plugs like those used with the latest Nokia phones.
But always confirm the compatibility of the adaptor tip with your mobile phone because some tips look identical but may have different pin configurations.
