TS100 - max 65W, TS80 - max 18W.
TS100 wins.
If they release a new TS soldering iron that supports USBC-PD of a much higher power rating, id grab it.
I’ve been using the TS100 for about 6months now and it’s amazing how well it works, even on thick 8awg wires. It heats up incredibly fast (in about 6 seconds to each 330degC), when paired with my 21V 4.62A laptop charger. Even made a 4S lipo pack for portability’s sake.
The only thing i hate about the charger is the lack of compatibility with USBC-PD. I would love to be able to use it with my 65W USBC charger.
