Better than nothing, but I've twisted quite a few prestas when filling my gravel 50-622 and my SUV's larger 29" mtb tires. These days, it's a complete backup pump for electric ones.

Awesome little pump. High volume / high pressure switch is very useful. Mount for bicycle frame is badly designed and hard to use though.

You can put air in a 26*2.4 tire.

A quality-feeling mini pump. You won't be able to mount any tubeless on the rim with this, but it will fill the tire in an emergency. Two inflation modes (above and below 40 PSI). Functional locking, but firm and stiff head.
