The battery life on smartphones is one of their biggest pitfalls these days, and being able to charge it via sunlight is something we've been dreaming of for a long time. Over the years many project have popped up, promising to do so, but none has delivered so far (solar cases can't do much, with its small solar panels). Now, SolarBook hopes to do better.
The SolarBook has just launched on Kickstarter, and is indistinguishable from a regular journal... except for the fact that one of its pages is actually a high-efficiency solar cell (23% efficiency) able to generate 5W of power (960mAh at 5V), which can charge up an iPhone in about 2 hours. We sure hope this time is for real.
If you're fast enough you can still caught the early bird package, for just $38 CAD. If everything goes according to plan, delivery should start in September.
