I understand that simply charging is fine, while video output is the riskier action because of unofficial docks that use a Switch-incompatible voltage for signalling. The wrong voltage can burn out a specific chip and require resoldering.

For what it's worth I sold the official charger/dock that came with my Switch more than a year ago and have been using only third-party chargers/cables plus a Covert Dock since then. No issues :)
