FP is a small company and doesn’t have the resources to test all chargers. But there is a community list of working chargers.
You can get a charger in FP’s shop, but not shipping chargers automatically with every order reduces e-waste alot.
That is true. Some companies even try their best to make sure that their phones and chargers are not compatible with other phones and chargers. Just so you have to buy their charger/cable after the first one broke (which it was designed to do after warranty ran out).
I’ll put the link to the list of chargers in the first post to make it easier to find.
