The Sun is known across cultures as the life giver. It is ultimately the source of energy that gives us light in the morning and whose setting in the evening symbolises the plunge into darkness of night. The sun is so important for our very existence we sometimes take it for granted. The sun produces 3.8 x 1026 Joules every second whilst we, on Earth, consume about 5 x 1020 Joules per year. There is plenty sunshine resulting from it’s reliable thermonuclear reactions to provide us with a steady generation of electricity. In just one hour the sun emits energy with the capacity to power 2,880 trillion light bulbs.
So we are agreed, the sun is a good source of energy. We know we have the means; and the technology has become increasingly available allowing us to create electricity at every opportunity. This post will look at the different options available.
Portable Solar Charging Systems:
There are even many sub sets of chargers within this category mainly being:
Pocket / hand sized chargers
The main difference between these being the surface area which is for generation. Obviously, the more area you have available to receive sunlight, the more power you can generate.
The reason you are using a charger, the sort of appliance or gadget you are charging will largely dictate what type of system you will want to use.
These include systems which are laptop or brief case size and which are intended to be unpacked quite simply to be propped up or free standing. This kind of charger is usually low voltage enough that you can wire directly into small gadgets like your cell phone or tablet without batteries and charge controllers.
Their size means they can be attached to a rucksack or placed in a window to enable quick charging in most environments.
A pocket charger is a small handheld charger which will mainly just power a cell phone / mobile. They are easy to carry around as they don’t require much space. Their uses are limited due to their size but are effective in what they are designed for. They tend to be the cheapest.
I personally recommend the OLEBR 24,000 mAh portable solar charger power pack for great functionality and value, which I reviewed in November 2017.
If you are planning a long journey or are regularly on the move and need solar power to be a big part of your energy requirements then a system intended for camping or hiking is more suitable. The difference between these kits and the foldable chargers being that the panels are more sturdy and do not fold.
A battery, charge controller and more wiring will be necessary to supply enough power for raised demand, usually beyond just 5 V and 12 V applications.
