I've got a reMarkable 2 whose USB-C port just decided to break one day. Tearing the unit down, I see the USB connector puts all of its strain on some very tiny pads. The pads were torn off. Apparently this is a common problem.
Based on this, I don't think their hardware is great, either.
Yeah, that's a known problem The solution is to get one of those usb-c to qi adapters, keep it always plugged in, and use a qi charger to recharge. This minimizes insertion cycles and stress on the connector.
