If the 12volt power outlet only comes on when the key is turned, then no. If the power outlet is on all the time, even with no key in ignition, then yes.
I had the same problem, went with a Victron "energy smart battery sense" monitor with a bluetooth connect to cellphone. see "Easy way to monitor 12V battery voltage" discussion for more.
