This is a solar charged battery backup for My HP mini 1032NR. The solar panel is quite small so charging is less than fast, I have not tested it yet but I assume it will take in the neighborhood of a week or so. It's all OK, the entire thing cost less than $50. For a comparable manufactured product you will be spending well over $300.00 according to my research. A quick note on the Life PO4 batteries "wally world" has them in a pack of 4 for $10.00 you will need 2 packs. They can be quite fickle so be careful with your connections. Nobody wants these things to start a fire. If you like this instructable let me know via comment I wiil post some more of my gadgets. For gods sake use a miltimeter and know the voltage of your pc. This project can be applied to any laptop not to mention a large assortment of portable devices IF YOU KNOW THY VOLTAGE!
