Does the mounting have a steady power connection? The manual says: “The mount also includes a 5 volt charger“ – Is this the only charging option?
Yes, it provides 5v of charging as long as the unit is wired for power and the breaker is pushed in. The device is provided with a wiring pigtail to attach to 28V DC aircraft power and a converter inside the unit draws that down to 5 volts for charging. Frequently customers cut off the connector and wire it without a connector, just using 2 splices, as the installation requires only two wires and they prefer to run them inside of the yoke column to their breaker. There is also a non-powered version of this product available.
