It should have it. If it’s the same converter I had been using, it may actually be the pot you cited as the current pot. I can’t quite remember…
Either way, they’re multi-turn pots, and so from fully off, it’ll take some turns to get to the tuning range. For current, I suggest starting from fully off, and then going up. The XR takes I think like 7-9 amps, I can’t exactly remember.
The low voltage cutoff throttles the current back as the voltage hits the cutoff, and continues to drop. The effect on the output is that the voltage drops continuously if load is still applied, until it hits zero or near that.
For the power bank I use, I generally shut it off near 90-95% or so to avoid it having to deal with an entirely full charge on its own.
