EDIT: If it doesn't get hot enough, make sure to use a USB adapter rated for at least 5+ V, 1A is rated ie 10 watts and it should get pretty hot. I've used the S10+ adapter with a USB power meter and it takes more than the 5 watt adapter can provide. toolbox. Powered by USB 5V, including power adapters. The third setting works well for lead solder, 15 seconds and you're done. I tried the tip on a friend's vape pen and apart from the auto shut off feature it works well. I will update if anything changes with further use.
