I recently bought a new Fairphone and official charger.
At first use the charger broke apart when plugging it out and the power connector was still left in the outlet (see photo). This is extremely dangerous as you can now touch the mains power. The power connector is also badly designed as this could be prevented by switching the male and female connector inside of the charger (see photo). Then you wouldn’t be able to actually touch the power if the charger broke apart.
I bought the power supply at 9/28/2020 so take care and check if your power supply is loose or something. DO NOT DO WHAT I DID ON THE PICTURE!!! Get somebody professional if this actually happens to you and turn off the fuse immediately.
My son has the same charger but bought it earlier and it seems completely fine.
