Preset pressure cut-off is the feature, not the maximum bar rating

The reason to own one is not the maximum pressure — it is the preset cut-off: you set a target in bar or psi, and the pump stops there without a gauge to watch, which matters most on the small-volume tires where a few seconds of overshoot is a large pressure error. We compare cut-off accuracy as stated, maximum pressure, battery capacity and how many tires a maker claims per charge, and which valve adapters are supplied for bike, car and ball use.

The stated capacity per charge decides what can be done before recharging. Across several bikes, that is the real constraint.
Many compact inflators top out below what a narrow road tire demands. Maximum pressure is a hard limit.
Many compact models top out below. The stated maximum pressure is a hard limit to check before buying.
Sharply on successive high-pressure inflations. Manufacturers impose pauses, which are not optional.
It gives an impression of precision the sensor does not always guarantee. A comparison with a known gauge is worth doing.
Most stop at the pressure set. That is the format's main convenience against a pump.
The flow rate is generally not enough to seat a bead. It re-inflates an already-seated tubeless tire perfectly well.
Many models allow it, with a long inflation time. Check the maximum pressure and the permissible volume.
Battery partly charged rather than empty, in the dry. A battery left flat for months may never recharge.
The device measures in its own circuit, and the gap with the tire sometimes reaches half a bar. A check with a separate gauge afterwards is still worth it on a road tire.
Many compact inflators top out below road tire pressure: that is a hard limit, not an order of magnitude. They get very hot in succession and the imposed pauses are not optional — and the flow rate will not seat a tubeless bead.
There is no table here, and the reason is in the listings. The figure published most often across these 4 products is modes, given by 3 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
