An automatic powering device includes a dielectric layer, a driving layer, a plurality of electrodes and a droplet. The dielectric layer includes a first surface and a second surface opposite to the first surface. The driving layer faces toward the dielectric layer thereby forming a channel between the driving layer and the dielectric layer. The driving layer includes a plurality of hydrophilic surfaces facing toward the first surface and a plurality of hydrophobic surfaces facing toward the first surface. Each of the hydrophilic surfaces is staggered from each of the hydrophobic surfaces. The electrodes are disposed at the second surfaces. The electrodes each are electrically connected to and spaced from each other. The droplet is flowable within the channel. The droplet is affected by the hydrophilic surfaces and the hydrophobic surfaces so as to flow in the channel.
