Hello,

I have discovered a project online that I want to improve on for a survival scenario. It's called the "Minty Boost" mobile charger. however i want mine to me more unique than theirs i want it to have:

* A solar cell
* 4x rechargeable AA battery module
* a DPDT Center off Switch
* a Female USB connector so i can plug in any device that has a USB cable to it to charge

The things I have a problem with in this idea is I have no idea how to go about doing this. Weather or not I need something that tells me when my solar cell has charged up my batteries fully, weather or not I need a few resistors or how many ohms I need in them, and what size/kind of solar cell I need to charge the batteries within a reasonable time.

I also want it to be highly mobile because I live on the go. so, I need it to fit in a good fitting container that opens and closes with the solar cell on the inside of the container so it is less likely to get damaged while I'm moving.

I will be highly thankful to who ever comes up with a way for me to do this,

- John-Michael Williamson

There are any number of solar device chargers for sale. Which ones have you looked at that do not meet your needs?

Well, it is more of a project that I want to do and construct my own that is different and compact. I don't want any major name brand product because of their cost. I really haven't tried any products but I have seen a concept that I liked that I wanted to modify so I could use it wherever and whenever. the product was called a Minty Boost (because it was constructed in an Altoids can) and the problem i had with their design is that they only utilized 2 AA batteries and the Solar panel was on top of the can.

Well, in light of this statement:
"The things I have a problem with in this idea is I have no idea how to go about doing this. Weather or not I need something that tells me when my solar cell has charged up my batteries fully, weather or not I need a few resistors or how many ohms I need in them, and what size/kind of solar cell I need to charge the batteries within a reasonable time. "

...it would seem you need some classes in electrical engineering and user interface design.
You don't just take a Minty Boost and slap a couple of solar panels on it.

But I urge you to go for it.
