Do the dock stations Dell WD15 and thunderbolt 3 are compatible with my XPS13 (9333) ? And do they charge the laptop?
No -- your system does not have Thunderbolt or USB-C.
Do you know any dock station compatible with my XPS13, that would bring power to the laptop?
There won't be any -- the system lacks the USB C port needed.
The only way to power the system is by means of the DC in connector from the AC adapter.
ok, thank you, too bad then. It would have been very useful
