Details about  Battery pack & Solar Charger for Raspberry Pi <ver2>

Here is a Solar and Battery unit suitable for the Raspberry Pi. 

Its a neat way to power your Raspberry Pi:

1. You can power your Pi directly from the sun using the solar panel and 4 x nimh batteries which act as a 'buffer' if the sun goes in

2. or... You can let the sun charge the batteries using the solar panel and then just plug in your Pi when you want to use it. - great to use free energy.

Of course, you can use the solar battery pack to power other Micro USB devices but the size of this panel is just perfect for the Pi and would form the nice basis for making a Solar Pi Project box.

This is a hand made unit not a professionally made device! - I made one for myself and find it very handy that I thought others might be interested. As you can see it includes a nice box to put the pi into - a great snug fit with holes made for the external connectors.

The panel supplies a little over 300ma (so for 3000mah nimh batteries means that it is charging at C/10) and has blocking diodes to prevent battery discharge. 

Typical Pi users are finding that they are using about 300ma-350ma an hour with various keyboards, mice, network and TV plugged in and running.  So the panel is large enough to run a number of typical configurations.  Of course if the sun goes in then with a fully charged (3000ma) battery pack you could get 8 hours Pi use with all that stuff plugged in and running, or if you are using less stuff plugged in and running, a lot longer.  The panel is large enough to charge the batteries in 10 hours.

The Raspberry Pi and Batteries are not included, but the micro USB lead obviously is.

Happy bidding and have fun with your Pi!!
