Systems and methods for charging unmanned aerial vehicles (UAVs) using ultra-low frequency wireless power transfer technology are disclosed herein. In some embodiments, a UAV can carry a wireless power transfer (WPT) unit configured to transfer power from a utility powerline to the UAV. The WPT unit can include a first field guiding portion configured to wirelessly couple to the powerline, a second field guiding portion operatively coupled to the first field guiding portion, and an induction coil operatively coupled to the UAV and at least partially wound around at least one of the first field guiding portion or the second field guiding portion. The first and second field guiding portions can be configured to guide a magnetic field generated by current passing through the powerline toward the induction coil for inductive charging. In some embodiments, the WPT unit can include a capacitor plate and a dielectric material for capacitive charging.
