The atmosphere contains ≈1.3 billion tons vapor that can be condensed to obtain water, which has the promise of alleviating the water crisis. However, condensed droplets are difficult to shed from the condensation surface that means a low surface refreshing frequency, showing the low water collection rate and efficiency. Here, this limitation is successfully overcome by proposing a novel superhydrophobic condensation absorber (SCA). All surfaces of the SCA are superhydrophobic but covered with a series of superhydrophilic through pores and superhydrophilic points which enabled the SCA with a rapid droplet nucleation capability. The whole condensation processes exhibit that the SCA has  the extremely small droplet shedding volume and the highly frequent surface refreshing, which are 0.00003 and 1.1× 10
