Does anyone know how the USB adapter and cigarette lighter adapter (under the armrest) can be powered continuously without having to start the engine?

Mine only works when the key is in the ignition or engine running. I'd like to have it powered continuously while I am out doing errands while the phone is being recharged. Any suggestions?
