Mulskinner [Hi-]Tech Review 3/2009
From the front-line of recommended hi-tech, here's now solar charger for mobile phones and small electronic devices.
The product, Solar SJ-2080, isn't quite as stylish and trendy as Solar-mobile would be, but it has many good qualities; fx it can be used to charge most phones on the market - The product comes with USB-cord that suits for the newest phones, for any other there's also various clips and pieces to user's particular phone. Additional benefits are that it can also recharge the battery (simply just open the cover and leave in sunlight) and phone simultaneously. The colour in led-light tells how much the battery is loaded and when its finished. Additionally the battery can charge from electricity grid if needed.
Their advertising it as an travel-charger, but more regular use is recommendable too. Since it shines only occasionally to my particular sanctuary, I try to take most benefit from that when it does. The paper within mentions charging time being about 10 hours, but naturally that's for the optimal conditions, and when cloudy or gloomy the time will be somewhat longer.
But I also noticed at first use that it didn't quite charge as soon as my phones battery run out, but when (solar) charger's battery was ready it permitted recharging phone about 1.5 times (the phone isn't particularly energy-hungry one). Of course, one needs also to find a proper place for the device and in most spots it shines only part of the day.
Even with these few 'barriers' for the lazy customer its useful invention, though the charging remains dependable on weather conditions. Best, of course is that the solar energy is produced carbon-free. Second important point is that the electricity generated with the device also is completely free (of charge). But, I found most reassuring thing that it also frees user from the 'false guilt' from the recklesness doings (and not doings) of the energy companies concerning the renewables development.
Of course, it may be only small effort on behalf the renewables in house-hold energy-use. But, couple decades solar will probably be available for more various electronics (and have become more efficient, too). While waiting for that development to reach MSW, it makes us finally also to wonder about the possibility to add an external solar panel in the device (that would reduce the charging time needed by some hours?). And afterwards it also makes me consider other suitable use for solar panels, though it remains less common in home electronics. But they're becoming more common even in kitchen cooking...
