Which is better for a stroller?

The FrSara. It is much smaller and lighter, so it clips on without weighing the stroller down. The Ateroll works but is a bulky 0.8 kg.

Which lasts longer on a charge?

The Ateroll by a wide margin. Its 10,000 mAh battery is rated up to 58 hours; the FrSara's 2,000 mAh is rated 3 to 8 hours.

Is the Ateroll worth stepping up to?

Yes if you need overnight or all-day cooling, a remote, or hanging mounting. If you only need short bursts of personal airflow, the FrSara covers it in a smaller package.

The Ateroll publishes a 24 dB rating. FrSara only claims ultra-low noise without a figure, so the Ateroll is the safer pick for a bedroom or office.

Can both rotate and change speed?

Yes. Both offer 3 speeds and 360° rotation.

Which is easier to charge?

The FrSara uses USB-C and charges in about 3 hours. Ateroll does not state its charge time.
