    The information given here is only valid for the following article purchased from BANGGOOD: ------------------------------ ID: 1582035___XY-UDP CNC USB color screen Power supply downward module Constant voltage Constant current 5V to 9 V 12 V 24 V USB voltage regulator USB tester ------------------------------ USB- power supply unit with recognizable potential for improvement ( noticeable weak points after the first 2 hours of playing around with this thing) (1) Disturbed DAB Receiving ...when supplying a DAB- portable radio, which is usually powered by a 231VAC/9Vdc power supply, low antenna levels cause massive interference with the receiving with the loss of a complete transmitter band (here: Germany; the complete WDR band), if the power bank, including this USB power supply, is located in the immediate surroundings of the DAB radio (up to 1m ... maybe even beyond ?). (2) The S-LVP switch-on problem ...to get to know the setting elements I had - just for fun - preset 12.0V output voltage (CV- Set Value) and 1.1A output current (CC Set-Value). The charging protocols were generally deactivated by "NOT-USE" and there was no load at the output ! I set the S-LVP (under-voltage-protection) threshold to 10.8V. But the module could not be switched on(?) Only after I reduced the S-LVP threshold to the basic value of 2.5V, the USB power supply could be switched on.If you now try to raise the S-LVP threshold to 10.8V, the USB power supply switches off again (?). (3) Fiddly setting switch SET-UP-DOWN ...(Imho) the haptics of this adjustment element is very much in need of improvement. Again and again it comes to a fiddly choppy adjustment situation. It's not so nicely solved.

    I bought this item as I wanted to have a really pocketable power supply. Together with a common battery bank, will allow to power small projects, breadboards, etc. without the need to be next to my lab bench power supply. It's also better that power a project with a battery, as it can e.g. set current limit (which can help avoiding damaging circcuts)

    very nice and good quality feeling, used just few minutes, but I already like it. the nice part is that you can add also the temp sensor. ;)
