I have a Mavic Pro.
I have just acquired a CrystalSky 7.85” with a WCH2 Charing hub (input17.3v-26.2v) and WB37 battery.  I assume the Mavic Pro F1C50 charger which  I have  (output 13.05v), is unsuitable if used with the Mavic2 to CrystalSky adaptor lead I have seen for sale (due to the low output voltage).
If so, where can I get a charger for this hub in the U.K. ?

Hello there. Good day and thank you for reaching out. The DJI WCH2 Charging Hub's charger need to have an input voltage of 17.3 - 26.2V and an output voltage and current of 8.7V, 6A; 5V, 2A. For reference I will post the list of compatible battery charger bellow. In addition, you may try checking our DJI Where To Buy platform on this link ( https://www.dji.com/where-to-buy ) to see the charger is available. Thank you.
