Charcher for batteries

The instruction indicates that max 1 Ampere should be used to charge the FP2. Would 1,2 Ampere create a problem - is the FP2 protected to prevent overcharging (like most/all other phones)?

I’m usually charging with a 2 A charger (since a year), everything works fine. I think 1 A is rather recommended as minimum.
