In these days of ever increasing reliance on expertise & devices lots of people have taken the choice to buy a universal solar charger. With more people purchasing web connected devices, the necessity for keeping these devices powered is more important than ever.
Solar energy works by converting the energy provided by the sun in to electricity. Solar panels are made from photo-voltaic cells, these cells were first made by Bell laboratories in the early 1950's. Briefly, photo-voltaic cells work by using the power of light itself. Light is chiefly consisted of photons which generate an electric imbalance within the photo-voltaic cells on striking the surface. This electric imbalance then causing an electric current to flow within a circuit created in the tool. This current flow can then be used to either power a tool directly or, more often in the case of a solar charger, be used to charge a battery which can then be used to provide power to another tool.
A lovely universal solar charger will be able to attach to a variety of devices. They connect either by the use of different tips for the devices or they can alternatively physically attach to the batteries which the tool may contain. A lovely quality charger will even be able to fully charge the tool using its internal battery.
It’s simple to come to the main advantage of a solar charger, chiefly that it does not need outside power to charge a tool. This is handy in the event you are going to be spending some time away from mains power. Examples include when camping or exploring the great outside or when spending time in a music festival which has toilets not to mention electric!
Solar energy is also environmentally friendly. Most domestic power is either generated by coal/gas powered power plants or through nuclear power. Both of these types of power generation produce harmful byproducts which can harm the environment. Coal/gas burning power stations produce giant quantities of greenhouse gases while the risk from radiation produced by nuclear power can never be dismissed.
In contrast, solar energy is a kind of renewable power. Along with wind & tidal power generation it is a tidy kind of power which creates no greenhouse gases & no radiation risks.
The next giant advantage is cost. Time you buy a solar charger there is no more cost involved in charging your gizmo, unlike mains power which seems to increase in cost every six months!
The largest disadvantage of solar chargers is that they need light to work. The efficiency of the photo-voltaic panels has increased greatly over the last decade or so, reaching the point where they do not need direct sunlight to work but will now generate a satisfactory current even under overcast conditions. But it is still something you ought to be aware of depending where in the world you are based.
Charging your gizmo by a solar charger may even be a lot slower than using a mains charger. This is due to the current generated by the solar panels being a lot less than what you would find at home. Universal solar chargers try to overcome this by utilizing a lithium-ion battery within it. These types of battery are excellent at releasing a higher charge than conventional ni-cad batteries, thus they generate a higher current in their charging circuit.
