We've upgrade the XTAR MC6C from micro-USB Li-ion charger to USB-C Li-ion & NiMH version. If you want a multiple slot universal charger, then this MC6C is a good choice! https://www.xtar.cc/product/XTAR-MC6C-Charger-111.html In 2022, we also upgraded some other micro-USB chargers to USB-C versions: MC1, MC1S, MC2, FC2, SC1 This change makes these small travel chargers more convenient to use on the go.
