In his review of the Nitecore UMS2, HKJ indicated that he selected a charging current of 100mA while he charged an 18350 battery. The measured current was about 150mA.
Me too. My UMS2 can have a selected minimum charging current of 100mA. Nitecore in its user instructions for UMS2 reported a minimum selected charging current of 100mA, with or without Quick Charge. When I watched the charging current being changed rapidly on the YouTube video by “Nitecore Store,” I saw “100mA” on my screen at time about 2:10
