This or the Nightcore UMS4? I know the UMS4 is $10 more, but for something like this the cost is less of a factor as hopefully it will have years of service. I am leaning toward the UMS4, seems to have more modes and be more advance but curious what those who are up in all the battery tech think.
ThatWeiThat looks like a good choice too, though it can’t charge 20700 or 21700. I don’t have any of those, but who knows what the future brings so I would lean toward a charger that supports a maximum number of battery sizes. Thank you for sharing.
