A mini electric bicycle pump packs battery-powered inflation into a compact body for a ride kit or small storage pouch. The ROCKBROS AS110 has a maximum pressure rating of 100PSI and a 7.4V, 300mAh battery. Its acrylic body measures 63.7 x 61.7 x 31mm, giving you concrete dimensions to compare with the space available in your bag.
USB Type-C charging uses a 5V, 1.5A input. Charge the pump before taking it on a ride and check the valve connection and the tire pressure required for your bicycle. This model does not have a display screen, preset pressure settings or automatic shutoff, so inflation needs your attention rather than an unattended preset cycle. Use a separate tire-pressure gauge to check the result. The compact format is the main difference here; do not choose it on the assumption that it includes the digital controls of a different pump.
