The product instructions listed a USB input but the device received had mini USB, USB-C and I believe a lightning connector (don't have any cool ones yet drunk help). Depending on your input, up to two amperes are distributed to four charging stations. I've tried each of the four and they seem to give consistent results. There is a meter that reads input values from 1/2A to 2A. The display will cycle (or can be manually cycled through) each battery slot, showing the total charge time, milliamp capacity of each battery, and percent charge. Either the charger or the battery was regularly not showing a capacity that matched the battery's advertised capacity. I can't believe some battery manufacturers lie about capacity. /Sarcasm font is disabled. Each battery looked fully charged when finished. The device cost a little more than I wanted to spend, but the technical details are (almost) worth it. highlighted.
