Nowadays, we have so many technologies like mp3, handphones, iphones which we use so much until the battery runs out very quick. Wouldn't it be better to have a battery charger which we can charge for most of our technologies?
Actually, evergo oxygen concentrators can solve the problem. I just saw it, it can be used to provide battery power for up to 8 hours. Wait, I am not that sure. I must check again to find more about it.
But it would be nice to have something like that.
