Hi all,
I am not charging a battery. I have a circuit that I would like to power with a 12.6VDC power supply (wall wart), not 12.0V. (why I want that is not germane to this question). My current draw will be in the 100 - 250 mA range. Although many 12VDC wall warts are readily available, the 12.6V variety that I can find are all listed as "chargers" (for example: https://www.amazon.com/MTYTOT-Universal-Adapter-100-240-Transformer/dp/B09X477NVB/ref=sr_1_3 ). They support Li-ion charging phases with an LED indicating:

I don't know what circuitry is typically in these to provide that functionality. My question is: Can this be used simply as a constant voltage power supply (no battery) if my load condition stays in the 10% to 25% of the rated capacity of the "charger"? Are there drawbacks to this relative to a standard power adapter? Might I have start up issues? Are things like ripple worse (or better?) with the charging variety? TIA!No-load status LED is green; Charging, the first phase of constant current charging, LED indicator is red. Charge to the rated voltage into the second phase of constant voltage charging, the current slowly decreases. When the battery power reaches 90-95%, LED lights turn green. At this point the charger will continue to charge with a small current until it is full.
