There are numerous portable battery backup solutions out there that come in various sizes, shapes and function. iTech makes one that falls into the ‘green’ category. How? By being rechargeable via solar energy. The SolarCharger 906 is a compact iPhone-sized (approx 4″ x 2.5″ x 0.6″) solar panel that holds 1,260mAh of power.
You can either charge up the 906 via a USB cable but of course, its star power (pardon the pun) is to be recharged via the sun’s rays. The 906 comes with a clear plastic cradle that is very securely connected and suction cups that you can use to attach it to your car’s windscreen. There’s also a car-kit.
The SolarCharger 906 has 4 blue LED lights on it that shows the degree to which it is charged up. Unfortunately, it takes over 20 hours to get fully charged up via sunlight, but iTech claims that it can keep a full charge for up to a year. So far, we’ve found that it does keep a charge for a week.
It also comes with 10 different power adapter tips including ones for LG, Nokia, Nintendo, Samsung, and Sony phones, Sony PSP and a few different USB tips (supports iPhone, iPods, Motorola and Blackberrys).
You can simultaneously charge a device while the 906 is charging via sunlight. Theoretically, you can keep the 906 running indefinitely if it gets enough sunshine.
We really liked iTech’s SolarCharger 906, but have to say that it is ideal for those folks that have their cars outside for a significant amount of time daily and use their portable devices enough to warrant an emergency backup. People that don’t fit this description may not get their money’s worth from the SolarCharger, although the 1 time you absolutely need your phone recharged, you may think just that!
When I first got a solar charger for my Nokia N95 all those years ago now it seemed that it simply couldn’t sustain the phone’s energy consumption for any decent period of time, but the new JOOS (pronounced ‘juice’) Orange solar charger is planning to change that.
Dell is one company that is at least trying to tackle the climate problem in whatever capacity they can. For example, here’s what I feel is a great idea: solar cell-lined shaded parking structures.
