Universal Solar Chargers Advantages and Disadvantages

In these days of ever increasing reliance on technology and gadgets many people have taken the choice to buy a universal solar charger. With more people purchasing web connected devices, the need for keeping these devices powered is more important than ever.

Solar strength works by converting the energy provided by the sun into 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 strength of light itself. Light is mainly consisted of photons which create an electric imbalance within the photo-voltaic cells upon remarkable the surface. This electric imbalance then causing an electric current to flow within a circuit produced in the device. This current flow can then be used to either strength a device directly or, more commonly in the case of a solar charger, be used to charge a battery which can then be used to provide strength to another device.

A good universal solar charger will be able to attach to a variety of devices. They connect either via the use of different tips for the devices or they can alternatively physically attach to the batteries which the device may contain. A good quality charger will also be able to fully charge the device using its internal battery.

Its pretty easy to come to the main advantage of a solar charger, mainly that it does not require external strength to charge a device. This is extremely handy if you are going to be spending some time away from mains strength. Examples include when camping or exploring the great outdoors or when spending time in a music festival which just about has toilets let alone electric!

Solar strength is also extremely environmentally friendly. Most domestic strength is either generated via coal/gas powered strength plants or by nuclear strength. Both of these types of strength generation produce harmfull byproducts which can harm the ecosystem. Coal/gas burning strength stations produce large quantities of greenhouse gases while the risk from radiation produced by nuclear strength can never be totally dismissed.

In contrast, solar strength is a form of replaceable strength. Along with wind and tidal strength generation it is a clean form of strength which creates no greenhouse gases and no radiation risks.

The next big advantage is cost. Once you buy a solar charger there is no more cost involved in charging your device, unlike mains strength which seems to increase in cost every six months!

The biggest 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 create a satisfactory current already under overcast conditions. But it is nevertheless something you should be aware of depending where in the world you are based.

Charging your device via a solar charger can also 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 conquer this by utilising a lithium-ion battery within it. These types of battery are very good at releasing a higher charge than traditional ni-cad batteries, consequently they create a higher current in their charging circuit.

This sums up the main pro’s and con’s of a universal solar charger.
