30 amp with adapter to110 outlet

You can run only basic things with the adapter to 110. The furnace blower is fine as its actually 12v so the 110 is just powering the converter to keep battery fully charged to power the blower and the circuit boards that operate the furnace and fridge. You might also be able to run the fridge but not anything else due to the limitation of the amps that can be drawn through the normal 110 outlet. Randu
