When the vehicle ignition is switched to off, the RAM Tough-Hub continues to provide power to the connected peripherals for a pre set duration of time. This unique RAM feature keeps your connected devices powered for quick vehicle stops, avoiding any possible connectivity issues. The timed shut off can be preset for: 5, 15 and 45 minutes. Although the technical documentation does not mention this, we have confirmed with RAM that this device also supports a 24 volt ignition source.
