Which power supply for GT Power X-Charger B620 1-6S 400W Balance Charger

I bought the following charger but it turned out that I’ll need a power supply unit as well.
GT Power X-Charger B620 1-6S 400W Balance Charger

Can someone recommend me one? I have Tattu 10000 mAh batteries.

Thanks

We have a charger 60W power supply, but just check what size connector your GT power X charger supports as it might not be compatible.

Thanks for the answer!

I’m not at home now but as far as I remember the charger does not have that type of connector but 2 big red and black cables as input. In that case what do you recommend?
Or what if I buy the one you mentioned with a converter for the connector?
