Amen. No AC charger includes a good enough AC/DC converting stage. AC/DC chargers are really DC chargers with a cheap transformer slapped in the box. To do a top-of-the-line AC/DC charger you would need a top-of-the line power supply IN the charger itself. This does not exist on the market today, AC/DC chargers just have a good old transformer in them for cost and space reasons. With the heat generated, their performance collapses, esp at 10A. This is not specific to LiPo, it's pretty much the case for all chargers as far as I can remember. Even my Tekin BC112AC/DC would collapse after 20mn at 4A back in the days.
Get a good PS, and on top get a good DC charger.
