Introducing the Tether Power Unit for the Elios 3!
The market leader in confined space drone inspections has announced the Flyability Tether Power Unit for the Elios 3. This is an all-new ground power system that delivers continuous power for uninterrupted inspections. By removing the need for mid-mission battery changes, the tether unit lets pilots focus entirely on the inspection.
The tether power unit connects to a wall outlet, generator, or compatible portable power station, converting 100–240 volts AC into high-voltage managed DC. Power is transmitted through a 50 m (164 ft) Kevlar®-reinforced cable with a tensile strength of over 50 kg, built for durability in demanding industrial environments.

Building on the existing user-friendly and collision-tolerant nature of the Elios 3, the Tethered Power Unit includes:
- A quick-swap air unit for seamless tether-to-battery transition
- Tension-decoupling swivel to eliminate cable stress and preserve flight stability
- Integrated backup battery for safe landings in case of unexpected power loss from the energy source
- Full compatibility with existing Elios 3 payloads
“Power tethering is highly complementary to flying with a battery to maximize the efficiency of our customers' inspection, surveying, and monitoring operations,” explains Patrick Thévoz, CEO and co-founder of Flyability.
“Following the launches of our new high-capacity battery and Smart Return-to-Home, the tether power unit reflects our focus on making inspections effortless, so our users can concentrate on gathering data over flying the drone, and in an increasingly autonomous way.”
