Broke my charger pin, what are the pin specs for replacement charger? (Priority current)

[ebikerr]

I am finding lots of very good reviewed battery chargers on amazon for 54.6V
The pin sizes are DC5.5 x 2.1mm, DC5.5 x 2.5mm


What should I choose for the priority current

Okay I found ones with adapters, i.e. both. Will order
