Istick qc 200watt charging question plz explain

Okay I just got the new istick QC 200w it says it's a trickle charge or Quick Charge but it only came with a 2A USB charger do I need a 2A wall unit to plug it into to be a quick charge, or can I plug the 2A USB into any wall charger and is it supposed to get warm when it charges idk I don't want to plug it into the wrong thing and ruin it or anything to go wrong, understand what I'm asking? Or is it jus supposed to plug into a computer
