That charger is 16 Euros or so? cripes, cheap or what.
I have the 10A version of this https://www.ebay.de/itm/314504751423...75.c101224.m-1 and I'm pleased at the versatility it has.
When you say older chargers were lower voltage how much older are you thinking? I also have several expensive Ctek chargers I'm not willing to scrap or sell as they are robust, tank built, reliable, IP67x and I have never had an issue in the 13-15 years I have owned them.
I'll use google translate to read the DE page, thanks
