Alex... thanks for the information on the adapter... I'm pretty sure that I did not get one, as I typically put everything like that in the pocket.. will check with GZ... mine is not a "plus" version... I typically charge the Guide 10 with the "solar" plug, not the USB... I wanted to see what adding the second charger would do to the operation of the Fujicell charger... it has a graphic charge status window...the other thread was on the AR15.com site.. sunshine today was brutal
