This air pump can be used for motorcycle tires — it’s easy to carry and can be powered ... you say to remove the three screws when there is actually a fourth screw hiding under the pop off cover.

The Presta-valve-only device is small enough to fit in a jersey pocket, weighs 190 g (6.7 oz), and can inflate a single 700 x 23C tire up to a maximum pressure of 120 psi (8 bar).
