Einova Wall Wart vs. ThermoJoe Heated Cup

I tried to charge my TJ power base yesterday from the USBC and then by the regular USB on my computer at work. After 3 hours it was about half charged.
Today I brought in my Einova wall wart I bought from Meh.
I drained the cup down to zero in a 3-4 hours. I plugged it in to the 100W jack on the Einova at 11:45. It is now 12:30 (45 mins) and it is basically fully charged.
The base is not warm. I was worried it would overheat charging too fast. I guess the circuitry draws only the current it needs.
I’ll post again if it explodes or starts smoking and leaking lithium goodness all over my desk.
