I think you misread the article.Interesting stuff, I like a mix of tech to go with the basics too, I've often wondered if Solar Tech had come along, I didn't really fancy the dinky handheld sized panels as I suspected they were little more than useless. It's still a sign that Solars got a way to go as even with that all spread out, in most conditions it will still only output the same as an average mains charger. That's a little disappointing considering the size of it, although it puts the claims of the smaller units into question.
IME the voltage remains pretty close to 5 volts but the current can fluctuate wildly depending on the conditions.
