Drone Docks and Charging

dock-in-a-box · battery swap · nests · BVLOS

A drone dock is a hangar, charger, radio site and data link in one box. Flight rules and trade policy, not charging power, decide how many docks get built.

Battery per drone on a log scale, all DJI models: Mavic 3 Enterprise 0.08 kWh, Matrice 350 RTK with two packs 0.53 kWh, Agras T50 agricultural drone 1.6 kWh, FlyCart 30 cargo drone with two packs 4.0 kWh. What a dock-in-a-box contains: a weatherproof hangar with heating and cooling, charging contacts or a robotic battery swap, navigation aids such as an RTK base station and weather sensors, backhaul over 4G or 5G, fiber or satellite, and edge compute for mission upload and video and data offload.

Finding

Drone docks draw so little power that energy never limits a dock network; beyond-visual-line-of-sight rules, airspace approvals and the US exclusion of new Chinese drone models do

An enterprise inspection drone such as DJI's Matrice 350 RTK flies on about 0.5 kWh, and a dock-in-a-box charges it at under 1 kW, so 20 docks draw less than one car fast charger. In December 2025 the FCC added foreign-made drones and key components to its Covered List, blocking authorization of new DJI models, while the FAA's proposed Part 108 rule (August 2025) would replace case-by-case waivers for flights beyond visual line of sight.

Most of a dock's cost is the box, not the charger: enclosure, climate control, RTK positioning, weather sensing, backhaul and the software that lets one remote pilot run many docks. DJI dominates the hardware with Dock 2 and Dock 3 (the latter vehicle-mountable for the Matrice 4D series), and Autel sells the EVO Nest. US alternatives are Skydio's Dock for the X10, whose battery supply was hit when China sanctioned Skydio in 2024; Percepto; and Ondas, whose Optimus system uses a robotic arm to swap batteries and payloads inside the base and was the first drone to receive an FAA type certificate. Swap trades mechanical complexity for turnaround in minutes; charging takes roughly half an hour per cycle.

Delivery drones use a different model: fleets of identical aircraft charging on pads or poles at a nest beside a store. Zipline (Platform 2) and Wing fly from Walmart stores in Dallas-Fort Worth, Wing is expanding to Houston and other metros, and Meituan runs drone delivery routes in Shenzhen with automated landing stations, plus Keeta Drone services in Hong Kong and Dubai. China's low-altitude economy policy and CAAC rules from January 2024 give Chinese operators a standard approval path that US operators expect from Part 108.
