Preset pressure cut-off is the feature, not the maximum bar rating · review
A portable inflator with a built-in hose, a 150 psi maximum, a 7.4 V 2.5 Ah battery and 4+N modes with auto-stop, sold mainly for compact cars.
Our conclusion A garage inflator that works on bikes as a side job.
Fanttik sells the X9 Pro mainly as a car tool, but it has what a bike owner wants at home: a set pressure, an auto-stop, and no pumping.
A 150 psi maximum, a 7.4 V 2.5 Ah battery, up to 23 minutes of continuous use, 4+N modes, auto-stop, a built-in hose you pull out, and a weight of 1.2 lb. Fanttik says it refills a compact car tire from 30 to 35 PSI in a minute.
Bike tires have small volumes, so a car inflator fills them quickly. The risk is overshoot: a fast pump can run past a target of 30 psi on a small tire. Set the target slightly below, stop, and check with a gauge the first few times.
Check the valve adapter in the box against your bikes. Presta needs an adapter on many car-focused inflators, and the bullets we read do not list the accessories in detail.

Fanttik states a maximum of 150 psi, which is above road bike pressures.
It weighs 1.2 lb and measures almost 8 inches long, so it suits a car or a garage better than a jersey pocket.
