This looks pretty cool and I wish I knew about it last month.
Though I'm not sure heating up in 7 seconds is fast and I wonder if it can keep a constant temperature during use, since they don't mention the wattage.
I just got my first decent soldering iron, a GVM T245 for 90 EUR, and it heats up in about a second.
Wattage depends on the power supply. USB PD gives you up to 60W. Barrel plug lets you bump the voltage (and power) up 20%. New firmware apparently let's you use EPR, which brings you up to 124W max, but you need a EPR power supply and cable.
The beauty of something like this is that its easily battery powered. It won’t be the fastest or most powerful option, but it’s an awesome tool to have on hand for repairs that aren’t easily done at a desk.
