Introduction: A Quick Video Showing My Latest Usb Charger

in this video you will see my latest usb portable charger. it is complete overkill, the solar outputs 25 volts regulated to 5 to charge anything usb, it can also recharge the double a batteries i use with a flick of a switch. there are two battery options, either two or one 9volt batteries or the 4 double a batteries. there is a SPDT switch that allows you to choose either the solar or a battery source, without accidentaly choosing both. so in short you can charge any usb device using solar power or battery power. you can recharge the double a batteries or pass the chagre to the usb device! the case i used is also water proof and durable as it can be.

So you have all your solar panels in series to get 25V?
If so, you should change it to parallel, as voltage regulators (like your 5v one) are a lot more efficient when the input voltage is closer to the output voltage. Just as long as it doesn't go below maybe 6 or 7 volts
