マイティミニファン

Bought this for my desk at work and it's surprisingly strong for how tiny it is. The Type C charging is convenient since I already have those cables everywhere, and it lasted my whole afternoon meeting on one charge.

Took it on a hot commute and that hour and a half of battery got me through the whole train ride without breaking a sweat. The little fan is surprisingly strong for its size, and being able to charge it with my phone's Type-C cable is honestly a lifesaver.

Ended up keeping this in my backpack for a week of city wandering, and that 1.5-hour runtime got me through every sweltering train platform just fine. The Type-C cable makes topping it off a total non-issue, even with my laptop charger.
