I, also, tried making coffee with our electric coffee maker using our onboard inverter. Nope.
Long about then we got a Keurig for the house. OMG, who knew!!! So THAT's what all the fuss is about. We're ruined for life. No more brewing pots of coffee for us.
So.... we buy a Keurig for the motor home. Tried it on the inverter. Nope. Grrrr.... Remember, we're ruined for life and MUST have our K-cup fresh coffee in the am.
A couple of years ago, I bought one of
these gizmos at Costco. It's a Goal Zero, Yeti 1000 Lithium battery with built in inverter, set up to be recharged using solar or 110 house current.
My wife gets the bright idea to plug the Keurig into the 110v receptacle on the front of the Goal Zero. EUREKA!! That thing loses all of 2% of available power to brew a cup of Starbucks finest dark roast in complete silence, and without touching the house battery storage.
This Yeti thing probably saved my marriage... just say'n
Excuse me.... I'm going to go brew another cup of coffee now....
