Have you had your ipod battery die on you literally minutes into a long train ride ? Looks like you'll have to find some other means of entertainment. Or maybe it's your cell phone that is low on charge and you talk to someone important. Suddenly it's silent at the other end and you look to see the display is blank. That sucks, you'll have to find a public telephone that works.
I'm guilty as charged. These days I want my entertainment or business ready at the touch of a button. That's probably why I have more gadgets and hand held devices than I care to think about. However they all need power and quite often I forget to charge them fully leaving me stranded. The solution to this problem is to use a portable solar power generator.
With the interest in solar power and the increase in hand held devices, there a number of good portable solar power generators around at the moment. The standard design is similar for most of them. A solar panel or cells will react with the photons in sunlight to create direct current electricity. This is passed to a battery that stores the electricity. The generator has a power point where various devices can be plugged in to use the current of the battery as if they where plugged into a wall socket.
The plus point for the solar generator is that if the battery is ever low the generator will use sunlight to recharge it. As long as the sun is shining the battery will be topping up or be full. Thus any mobile or portable appliances that you have will have a power supply. You will never have that flat battery experience again.
If a portable solar generator sounds like something you need then here are a few pointers on selecting one. You should consider the efficiency of the solar cells in the generator. Larger panels will be able to charge a battery quicker. However you don't want the generator to be cumbersome. You need your solar power generator to be similar with regards to size with the portable devices it will be charging. It should be easy to carry round on a belt or in a backpack.
Another factor is the length of time the battery will power a device. A good test of this would be to determine how long a portable dvd player would last using the battery. Obviously the longer time this is the better but again size will be a factor if you want it to be truly portable.
Finally, you should check out what portable appliances can be plugged into the generator and how easy this is. At a base level, it should be compatible with your cell phone and any of personal digital appliances you may have (including a gps device if you do a lot of car traveling). You will probably use it most often with entertainment devices like PSP's , portable dvd players and mp3 players so it should be compatible with these devices too.
