First, don't let your voltage get low because rather than cutting off like you might hope they will simply keep trying to supply power at below the voltage level. This could damage some electronics, so use some sort of limiter (like a CJKIT-20462) to protect from low voltage if it matters for your application. (and the life of your battery!)
Second, they will audibly oscillate when drawing more than about 1A from a higher voltage source. You can hear the high pitched whine if you have sensitive ears. This annoying feature can be mitigated by lowering the input voltage.
* Third, and critical if you are operating on battery power: if your voltage source is substantially higher than the output voltage, this may burn a lot of amps even when the load draws little to nothing. My setup involves converting 25-28V down to 12.25V and sometimes (but not always) by my measurement this wastes 1.5A in the converter, with the actual load drawing only 50mA. Bringing the voltage down to 20V or lower will drastically curtail this waste.
So you might think to wire these into a 24V system in series to deal with that issue, but they don't seem to tolerate being wired in series with each other. Only one or the other seems to work at any given time in my installation.
This order came straight from China, so it took two weeks to fulfill, but the price was good.
I will use another one in the next project. Those regulators are tiny, yet efficient, so they do not dissipate too much heat.
I suggest you hang a directional diode on the output + terminal to stop any bleeding back. Find those here,
Amico 10 Pcs Molded Plastic Case 1000V 10A Rectifier Diodes 10A10. Also cheap but very good quality.
I used a dab of liquid electrical tape to semi-permanently hold the potentiometer in my desired position.
One small downside... not really a downside, more of a note is the response time of the unit, apply a load and the device has to churn around a little bit before it stabilizes the voltage. I have not measured it but it may be confusing something I am powering with it. I have measured similar 'sag' when using one as a battery pack replacer in a hand held marine vhf radio when I hit the send key.
