Just bought a Coolpix S9900 which has a EL-EL12 battery installed. When travelling I like to take a single charger. I have an Anker 60W 6 port USB charger which I use to charge my iPad, iPhone, GoPro, GoPro remote etc. and it all works well.
I'd like to use the Anker for the new camera too but there are dire warnings in the instructions about using a non-Nikon charger (although it does say I can charge it from a PC's USB port).
I went on to Nikon support's on-line chat this morning and all I got was a warning that no third party chargers have been tested but using anything other than a Nikon branded charger could cause a fire!
Can't really believe that but would be interested to know whether anyone else has used a third party charger on a similar camera before I have a go (the wife would get very annoyed if I burned the house down).
