Okay.. I did it.. I made a fully functioning field charger for my
Suunto X9mi
Things you should know. The standard USB Pin arrangement does not work for
Suunto watches. I called to see about getting some help and someone at
Suunto USA Technical help sent me to
SUUNTO X9i Compendium
So I will not take any undue credit. But I followed his instructions and ended up with a fairly good results
I am using a Brunton
Solar Roll which provides 18V (on a sunny day) of power that is brought down to 5.5V with a standard Car USB adapter.
So looking at the initial results. I am pretty pleased with the results..
