These are the units:
Douk Audio U3
Which USB charger brand should I purchase for these ? Amazonbasics, Anker, Samsung or Ugreen ?
I already have a Samsung and a LG charger, Should I purchase additional ones ? Do I get any benefits by purchasing better chargers than I already have ?
Does it matter if I use a very cheap charger bought from a dollar store ?
Will there be a significant improvement in sound quality if I buy more expensive chargers ?
very cheap might have problems, I personally didn’t notice a difference between a reasonable one and a $100 “audiophile” one
Ugreen and Anker have been really good in my experience
I have an OEM Samsung 5V-2A and two OEM LG 5V-1.8A USB chargers…Would you say that these have enough power quality ?
if they are somewhat new and support the power you need should be fine, I was using one that came with my old phone (2013ish?) for a while to power a Douk U2 pro and a Toslink splitter without issue
The Samsung one was for a S9 phone…The LGs I don’t remember but they should be post 2011 ?
If the chargers have low power quality, what are some of the signs or audible signs that I should look for ?
more background noise/ less volume at the same level would be the most likely issues
