The Fujifilm X-T3 is Fujifilm’s most feature filled camera for using an external battery with it and Fujifilm has released some guidelines for which battery banks to use. Fujifilm recommends the Anker PowerCore Speed 20000 PD and PowerCore+26800 PD, but you should be able to use any USB-C charger.
The Anker PowerCore battery banks are currently 50% off, but there are other more affordable options at this time so they might have their prices permanently reduced. You can read more about how the Anker battery banks perform with the Fujifilm X-T3 below.

the mobile battery supplies power to the camera, so that the power
consumption of the battery in the camera becomes less. It is very
useful especially for a continuous shooting like a movie, time lapse shooting
and so on. If the camera turns off, a battery charge automatically starts.
