Purchased: 2025-09-03

Received the 12s Di2 charger that was discussed many pages back when it was a mixed bag quality. This one is branded RRSKit. Looks like a serious factory has taken up this design: no more 3d printing, the casing is cast from ABS plastic, all contacts and ports look solid. Works perfect both with a mains charger and my power bank. Definitely recommend.
