Solar Charger for M8 mini charger

Ever since I unpacked the M8 and found the charger had a 12v plug I have wanted to charge using a solar battery of sorts..

I played with the carabiner with a solar panel style gizmos from solio etc... those proved a bit to lightweight for the job.. some could start the charge but nobody could finish the job.

So I talked with a factory I work with in china and got them to modify a laptop strength charger for me, adding a 12v out and a USB port. after all what is a good day without a few tunes from the iPod.

This week I received a box with 3 copies of prototype number 1. it works just as hoped, the battery charges in a full day of California sun. and it is able to deliver a full charge to the leica battery. actually I am pretty sure it will do several charges, but did not have a bunch of flat batteries to toss at it yet.

The battery is 400g 2700mAh a bit lightweight for a laptop, but very portable, and it will put a charge on my netbook just fine. The solar panel 37x26cm 9v 0.6a
