Trickle charging from solar - can it damage the battery


I’m looking into getting a portable solar charger - I came across a cheap foldable amorphous camping charger.

Will this work with the FP2 and if so is there any chance it can damage the battery to have a slow charge going into it?




I can’t answer in a technical way, but I can tell you that I have been using one for almost two years and that it did not damage ma battery (at least not as I can see). Other Fairphone users also regularly use a solar charger. Check these pages:


Damage should be prevented by the charge controller in the phone, so as long as the device provides 5V it should be safe to use.
